Any chemical company manager will have to admit that order fulfillment isn’t over until the product is in the hands of the customer.  Chemical manufacturing isn’t just about running reactions in big pots.  It’s about attracting a skilled, reliable, and safe work force. It is about building a supply chain for the timely delivery of raw materials. It is about executing the manufacture of products in spec the first time through. It is about warehousing raw mats and products and keeping the stream of wastes moving through the system.

Chemical manufacturing requires the careful management of cash flow by minimizing costs and maximizing profits. The business office must attend to receivables and collect payments in the most expeditious way that customers will tolerate. This is no different that any other manufacturing arena- sprockets, fur caps, or rocket motors.

One of the key jobs required of any chemical company is the matter of managing logistics.  That is, managing the timely transport of raw materials onto the site and the transport of products off the site. So how does this affect the chemist??

The tender shoot studying chemistry in their junior year of college may not know it yet, but if their path is in the fabulous world of business, then some aspect of logistics may be in their future.  What kind of chemist would need some knowledge of shipping? Well, project managers, sales managers, business development managers, plant managers, procurement managers, etc.  All these positions are often filled with chemists and all have to have some knowledge of this topic.  And how does one get this knowledge? Why, on-the-job training, of course.

If you have read many of my posts, you know that I tend to prattle on about this. There is a reason. It is not uncommon for a sales person or a business development manager to spend no small amount of time with a customer trying to work out how the product will be delivered.  The transport of materials is complicated in proportion to the hazard and the chemical sensitivity to decomposition. 

Let’s say that you are in the chemical business and you are just starting the custom mfg of a trialkylphosphine.  The customer will state that they want say, 100 kg, of their R3P with a list of specifications (e.g., 99% in R3P, oxides < 0.1 %, etc, Karl Fisher water 200 ppm) for their new product. The customer has accepted the quoted price and the delivery date. Hmmm. Price, delivery, and specs. Sounds like everything is in place.

So, the question then arises: How are you going to ship it? Glass bottles? Drums? Polyethylene totes? Whoops, the material is excruciatingly air sensitive, so charging and discharging the product will have to be done airlessly. Sounds like a cylinder is just the thing. But what are the materials of construction? I seem to recall that phosphines are ligands, so can we really use a steel cylinder? Soft steel? Stainless steel?

But there is yet another question.  Do we offer the phosphine neat or as a solution? If the neat R3P is a liquid, we can move it around airlessly and charge a cylinder with it. If it is a solid, then it could be a serious problem to transfer it from a filter to a shipping container. How will you or the customer actually handle it? This is the kind of detail that chemists might find themselves groping with. If it is a solid, the customer might have to consider receiving it as a solution in a non-interfering solvent.

Then the matter of transporting it arises. In the present epoch of security theatre, air transport of any quantity might be banned. So, surface shipment will be needed. The matter of heated shipment may arise if freezing or precipitation is an issue. The last thing anybody needs is a cylinder full of precipitated solids in it.  Remember, if you are shipping product in a heated trailer in the winter, you may have stiff competition from other customers who need to ship their lettuce or strawberrys. In some locations, reefer trucks as they are sometimes called may be in short supply.

OK. So you’ve specified a reefer trailer for heated transport of the goods. Let’s say that the product solution will crash out precipitate at 15 C. In the trailer everything is just fine. Fine that is until the shipper reaches a transfer point and moves the product out onto the loading dock where it sits in the freezing weather for a few hours waiting to be put into another trailer. Or it sits in unheated warehouse space for a while.

Eventually, the cylinder of R3P solution arrives and, sadly, has precipitated and won’t come out of the cylinder. So there you are. The customer is unhappy and you now face having to haul it back and recover the product. These are the kinds of problems that chemists on the business side (the plow horses) can find themselves dealing with. Of course, the R&D chemists (the show horses) are rarely bothered with such things.
