With uptick of natural gas exploration and “recovery” happening, you have to wonder if anyone is bothering to look for helium in it? And I’m referring to the Marcellus shale formation in particular. Wouldn’t it be nice for some forethought here and try to recover some of the helium that may be lost. Helium is a non-renewable resource and is critical to many industrial sectors, including superconductor applications.
The US has held helium in reserve since 1925. Helium extraction has been most fruitful from gas wells in the western states. The Helium Privatization Act of 1996 has resulted in the release of the helium reserve to the private sector at a federally mandated price. The FY2011 price is$75.00 per thousand cubic feet.
According to the BLM, the agency that manages the strategic reserve, their enrichment facility in Amarillo, TX, can produce 6 million cu ft per day of crude helium at ca 80 % purity. The Amarillo plant provides crude He to refiners who polish it to the necessary level of purity for the end user.
Saw Bassam Shakashiri do his “Chemistry is Fun” demonstration last night. On the way home in a rain storm my radiator blew out while tooling along the interstate in Denver. On phase two of the trip with the tow truck driver, I heard his stories of driving a tow truck in Telluride. And his travails with his ex-wife. And why he stopped drinking. And being in traction after a car crash. And about his ex’s brother the cop.
Seems he towed Tom Cruise’s Range Rover and one of Oprah Winfrey’s cars in Telluride. According to the driver, Oprah came running out the door and paid him handsomely to leave the car. Even the fabulously wealthy have to get towed now and then. Heavy is the head that wears the crown.
Spring 1980. I arrived at the airport at 6:30 on a calm morning along the front range of Colorado. Judson Flying Service was open for business with a modest fleet of Cessnas. Two 150’s, a fairly new 152, a 172, a 182, and a 210. I had 48 hours of time logged in preparation for my checkride.
My flight instructor, Fred, had signed me off for the checkride after my successful short and long solo cross country flights. We had practiced a bit on the short and soft field landings. I loved landings. If there is a time that you feel that the machine is an extension of your limbs, it is during the landing phase.
I nearly had to cancel the checkride. I had contracted a bout of conjunctivitis following a visit to the opthamologist. My eyes had cleared up sufficiently so I decided to proceed with the flight test. Scheduling with the FAA designated examiner was hit and miss so I didn’t want to miss my slot.
The examiner gave me a destination- Yuma, Colorado. My job was to put together a flight plan and call it in the flight service station (FSS). While on the line with the FSS, I got a thorough weather briefing. I plotted a course based on radio navigation stations (VORTAC), estimated time enroute and fuel consumption, identified several alternate airports enroute, and collected the various radio frequencies and ground references for dead reckoning.
We were ready. We walked out to the airplane where I did a thorough preflight check and answered questions on aerodynamics. Satisfied, the examiner and I strapped into the Cessna 150 and began the engine startup procedure. He pulled a few tricks including leaving his belt unconnected and didn’t completely latch his door. Having the door pop open on takeoff is startling for everyone, pilot included.
The 4-cylinder horizontally opposed Lycoming engine lit up after a few turns like it always did. After checking to see that the oil pressure was in the green and that the fuel gauges indicated what we observed by visual inspection, we taxied to the runup area on the taxiway near the start of runway 29. Pointing the nose toward the approach airspace of 29, we went through the pre-takeoff checklist. Breakers look fine. Radio check. Adjust the mixture. Run the engine up to 1600 rpm and alternately switch off the two magnetos one at a time to look for function and for a worrisome loss in rpms. Verify that flight controls are operating properly and that the flaps are set to the recommended position.
It’s settled. The machine wants to fly. We’re going aviating. A serious scan for incoming traffic and, noting none, we radio to what traffic there might be that we intend to depart on runway two-niner and leave the traffic area to the east.
I release the foot brakes and taxi onto the runway. After we turn onto the active runway the throttle goes to the firewall and the engine promptly revs up to full power with that righteous unmuffled roar from the engine. We’re a little on the heavy side with two adult men on board, but N63110 still accelerates smartly down the runway.
As we begin to accelerate with my left hand on the yoke and my right hand on the throttle, I’m busy keeping the nosewheel on the centerline of the runway with the rudder pedals while glancing at the airspeed indicator. The airspeed indicator seemed sluggish. As we get close to what appeared to be rotation speed the airspeed indicator still didn’t register any airspeed.
To actually launch into the air without airspeed indication would be a huge mistake. Not only would it be terribly dangerous, but I would fail the checkride if we survived the ride around the patch and the landing ordeal ahead. So, I pulled back the throttle and applied heavy braking. We taxied off the active and made for the shop. No available 150’s that morning, so the checkride was canceled.
Turns out that some bugs had nested inside the pitot tube overnight and blocked it.
Flying very much depends on making sure that the airflow moves over the wings above a minimum velocity and within a range of acceptable angles. Without airspeed readings, the approach to landing would be very sketchy. The landing phase requires that the pilot slows the airplane so that a glide is established to the ground. The glide speed is easily controlled by adjusting the pitch of the airplane. In a normal landing it is nose down. The sketchy part is that the airplane is close to stall speed during this phase and so any kind of loss of controllability or lift near the ground will have dire consequences.
A week later I arrived at the airport at 6:30 on a cool windy morning along the front range. This brisk morning the winds were out of the west at 12 kts gusting to 14-16 kts straight down runway 29 with a broken ceiling at about 9000 ft above sea level, or 4000 ft above the ground. The winds were squirrely for a 150 but not bad enough to cancel.
I repeated the flight planning of a week ago and we walked out to the airplane and strapped in. The FAA examiner had a hood with him for use in simulated instrument conditions. I looked at the hood with some dread. Performance anxiety, really. But I had a fair amount of hood time and had always done fine.
We take off and point the nose to the east and climb to 7500 ft MSL. The winds were strong at altitude and turbulence was making the flight somewhat strenuous. I had precise flying to do with a strong silent-type examiner. After I lock onto the VORTAC and verify the station’s Morse code identifier, the examiner hands me the hood and announces that I just flew into a cloud.
Being prepared for this I put on the hood which resembles a welding helmet except it has a narrow blinders protruding forward to block the view outside the airplane but still allow view of the instruments. It is used routinely for simulated instrument flying.
I tell the examiner that the flight to our destination is aborted and that we were returning to the airport by doing a 180 degree turn. The idea is to turn around promptly to the reciprocal heading to exit the clouds most expeditiously.
Being a cocky 23 year old male I smartly roll the airplane into a left 45 degree bank and try to intercept the reciprocal heading. While executing this and while fighting turbulence I overshot the heading. So I roll the airplane into a right 45 degree bank and try to intercept it again. Again I overshot it. By this time some dizziness had set in to complicate my cockpit chores while I try to remember what the desired heading was and get back to my designated altitude.
With the excessively steep turns and the turbulence I had managed to lose control of the aircraft under simulated instrument conditions. I didn’t realize it at the time, but I also had vertigo. As I wrestled with the flood of seemingly contradictory instrument readings, a tumbling gyro, and distracting g-forces I continued to try to wrestle the machine into level flight.
The examiner just sat there. Legally he was just a passenger. I was the pilot in command.
My mind was overloaded with fear. My brain was trying to reconcile the what my inner ear was telling it with what the turn and bank indicator, altimeter, and airspeed indicator were telling me. I had fallen into a classic and fatal combination. It’s called the “graveyard spiral” or the spiraling power dive. I should have done a gentle standard rate turn and avoided the g-forces and higher skill needed to maneuver like that.
When it became obvious that I wasn’t going to recover, the examiner took the yoke and corrected the turn as he told me to take off the hood. As I removed the hood I saw in front of me a great circular corn field with center pivot irrigation slowly wetting down the field. We were perhaps 500 ft above the ground and still in a dive.
Grateful that the examiner had left something for me to do to save the flight, I retarded the power and carefully pulled out of the dive. The airspeed needle was was adjacent to the red zone.
I climbed back to a cruise altitude and flew back to homebase. The examiner wanted to do some other test items, but I was so humiliated that I wanted to get back on the ground. Once back in the traffic pattern I set up a short soft field approach and executed the best landing I had ever done. The wheels kissed the ground and came to a stop without wasting even a foot of ground. The pride was wounded but the skills were there.
A week later and after a humbling hour of remedial hood time, I retook the flight test and easily passed it. The same examiner signed my ticket. He never chided me or said anything to humiliate me. I think he knew that a major life lesson had happened and was glad that it was under supervision. I have never forgotten the corn field that should have had a smoking crater in it on a blustery day in June, 1980. When I close my eyes I can still see it.
So it turns out that I am the family atheist and liberal. The social awkwardness and philosophical incompatibility of this condition was evident the other day in a discussion with a family member that diverged into a shouting match. In fact the immiscibilityof my liberal atheist proclivity with my family’s generally Christian conservative foundation has severed ties with a few family members outright and distanced others. My father, deceased nearly a decade ago, never reconciled with his son’s atheism. In his view, it was a choice inevitably resulting in existential tragedy and damnation into the darkest recesses of infinity.
My wife is a Methodist and our kid is being raised under that umbrella. I have taken the position that I will not indoctrinate my child in the analytical consequences of atheism. Rather, the adoption of a philosophical position on existence is a self-guided adventure everyone is entitled to. Whether one is lead deep into the doctrines of the Abrahamic religions, eastern philosophy, or the uncertain swamp of agnosticism, it is the right of all people to come to their own conclusion on the matter of ones place in the cosmos.
I claim that this is a right. But many otherwise liberty-loving people disagree. They view indoctrination into the religious fold as a kind of rescue. It is a dash across the finish line that must to happen well before death to ensure that the soul is channeled into the chute leading to paradise. Once in this enviable condition, the ethereal community of souls can eternally heap praise upon the diety directly rather than across that impenetrable supernatural discontinuity that is resistant to all but the force of prayer. Or so goes the core theory of the Abrahamic religions as I understand them.
To many religious followers, the very fact that their religion is ancient seems to validate the accuracy and veracity of their ideas. The mere continuity of these doctines seems to confer some hopeful message about the vital truth of the doctine.
But I would counter that what continues over time is not the cosmic accuracy of the idea, but rather the psychological consequences of brain physiology. Architectural features of the brain and the behavior of neurons therein have produced self-awareness. The self-aware brain enables much possibility for an organism. An effect of our self-awareness is that we come to experience time.
But the very familiarity of self-awareness of the human brain might lead it to assume or calculate that self-awareness is a common condition in the external world. It seems to easily conclude that the apparent organization of the world was conducted by a central organizing influence- a diety. Moreover, it is not unreasonable for the self-aware brain to assume that it’s own self-awareness is part of a continuum of awareness or consciousness. The notion that self-awareness might extinguish would be inconceivable.
I think what the ancient religious texts and doctrines convey is a kind of familiarity. It is a shared experience of mystery, uncertainty, and fear through the common experience of consciousness. The brains of our ancestors communicated through the agency of language their chronicles of hope and fear to our brains which share the the same strengths and weaknesses. It is this commonality that rings the bell of truth in our self-awareness. It reinforces the mystical experience as a physiological experience because it is fundamentally that.
What is inevitable about our self-awareness is extrapolation. Religion soon mutates from a personal mystical experience to a theory of physics and politics. This is what I cannot accept- Religion as a political template or as a ToE (Theory of Everything).
Many people come to value alignment to doctrine as a higher calling than the application of love and charity to their fellows who have lost their way or have experienced bad luck or tragedy. I would offer to the reader that what makes a person liberal is the priority choice of people over the politcal doctrine of social Darwinism.
We in the USA have confused economic theory with reality. Economics and business are a subset of sociology. The alleged congruence of economics to morality or metaphysics is a political theory some people have asserted because it serves their purpose in the allocation of wealth. It’s a part of their ToE. And I’m here to say that some of us can see what they’re doing.
In the last 6 months I have learned a bit of what extractive metallurgy is about. One of my projects involves isolating an element from an ore where the desired element is one of many minor constitutents. What is important here is the term “minor constituents”. When the desired element is a minor constituent, then one necessarily faces the prospect of processing large quantities of mass.
Processing large quantities of mass requires that the material and energy inputs used in the process must be very inexpensive. Except for gold, you have to start thinking of heat as a kind of reagent that can be applied to make things happen. The lucky circumstance with gold is its affinity for cyanide in an oxygenated aqueous environment.
It is a very interesting and worthy challenge to start with rock and contrive to remove purified products from it. Half of the fun is working with the engineers and metallurgists. They have a very different perspective of industry than a stiff like me who has always relied on Aldrich for “raw materials”. I have had to recalibrate a bit. You don’t meet people like this at ACS meetings.
I have spent more than a little time digging into extractive metallurgy from the 19th century. A good deal of fairly sophisticated technology was worked out long ago for many metals on the periodic table. Mostly, what has changed between the metallurgy of yesteryear and today is that we now consider fairly low grade ore as economically viable.
The tailings of yesterday will become the ore of tomorrow. It just depends on the value. When you drive around the gold and silver mining districts in the Colorado Mineral Belt, the tailings that you see from the road have most likely been worked over at least once.
I don’t know where others sit in the chemical industry, but the view from my chair seems encouraging. The market is abuzz with activity. The chemical industry and the people who run it are, well, rather stodgy. So to see lots of rfq’s flying around the ether is encouraging.
Every day I wake up and thank whomever will listen that I did not go into pharmaceuticals. There is a vibrant world outside of pharma and I’m glad to be in it. Those of you in pharma, I’m honestly happy for you. I’m relieved that so many bright people dig that brutal business. But for me, I’m glad I let that bus go right on by. The public corporation GMP life is not for me.
I have a PhD and a post doc in asymmetric organic synthesis. It was interesting at the time and admittedly hard to let go of, but I have few regrets today. If I’d have stayed in academics, I be teaching my 18th year of 2nd semester organic or (*gulp*) general chemistry and doing battle over meager and diminishing departmental budgets. That is, if I had survived student evaluations. What dipshit thought of student evaluations as a tenure and promotion metric? The little punks should be grateful to be sitting in the classroom. Well, ok. That was a bit harsh.
I think the best part of having a background in synthesis is that you become very mechanistically oriented. Latent and blatant functional groups bristle and are pregnant with possibility. The ability to make a good stab at what happens when two molecules interact is a very powerful thing and I’m grateful for what little I can do. And if you think that is false modesty, just try to go back and make sense again out of ligand field theory or lanthanide chemistry. Chemistry is a big field and much of it remains unfamiliar.
Now that my abstract for a talk at the upcoming ACS meeting in Denver has been accepted, the reality of it has sunk in. I still have lots of data to collect and sense to be made out of it.
I resolved a few years ago that I wouldn’t go to an ACS meeting again unless I had something to present. It is very depressing to go to one of these extravaganzas and not be able to participate. One of the down sides of generating proprietary information is that you rarely get to present it at meetings to the scientific community. A negative side effect is that it appears to students and our academic colleagues that nothing much is being done in industry if the lion’s share of results are being presented by the university research establishment.
Had the chance to visit a lab today with an XRF and a GDMS. It was very interesting. Even though I’m an organikker by training, I have to say that I really dig haunting other parts of the periodic table. Organic chemists are spoiled by the splendid richness of multinuclear, multidimensional NMR. But when you stray from C,H,N, & O, composition and structure can become much more problematic.
The XRF samples were prepared as a lithium borate fusion in a Pt mold in the muffle furnace. The vitreous buttons were then placed in the instrument sample station. One of the problems with XRF, like any other kind of spectroscopy, is the occasional interfering peak. But, like the famous British philosopher M. Jagger once said, you can’t always get what you want.
The GDMS was a sight. This instrument is sensitive to sub ppm levels all over the periodic table. At this level, just about everything shows up to some extent. The concept of purity becomes muddied a bit, at least for mining samples. For most things there aren’t good standards at this level. You have to trust in the linearity of the instrument and be happy with 30 % error.
SpaceX has announced their Falcon Heavy lift rocket. It consists of two liquid fuel rockets astride a longer center rocket. Each of the three rockets has 9 Merlin rocket engines. SpaceX claims it will lift 53 metric tons into low earth orbit- twice the payload of the Space Shuttle and more than twice that of the Delta IV. Depending on configuration a launch will cost between $80 and $125 million.
This seems to be real progress for the space business.
