The term “Rules of Thumb” is thought to originate with carpenters who used the length of the tip of their thumbs (i.e., inches) rather than rulers for measuring things, cementing its modern use as an imprecise yet reliable and convenient standard (Wikipedia).

How do Rules of Thumb relate to the chemical engineering profession? While imprecise standards may seem the opposite of what engineers need in this computer and data driven world, the fact is that we use approximations all the time. For example, we size control valves to take about 20% of the pressure drop through a pipeline, and plug that goal value into expressions carrying five “significant” figures. In another example, we design CIP systems to deliver detergent to process vessels at a rate of 3 gpm per foot of circumference. Where did that value come from and what is its meaning?

Mr. Hall will discuss plant design and rules of thumb with examples, advantages, and pitfalls.

About the Presenter:
Stephen Hall brings proven and trusted expertise to drive engineered capital projects for pharmaceutical manufacturers. He leverages his technical know-how with his management background and broad regulatory compliance experience to benefit the engineers, scientists, and operators who are tasked with executing the design, construction, start-up and qualification of new or renovated manufacturing facilities. His book, Rules of Thumb for Chemical Engineers, gives practical advice, information and mathematical formulas that are used by process and project engineers throughout industry (Butterworth-Heinemann, 2012).

Steve earned his B.S., Chemical Engineering, from the University of Pennsylvania and his MBA from Drexel University. He authored numerous articles for Pharmaceutical Engineering, Chemical Engineering, Chemical Engineering Progress and others, and presented at various professional meetings.

Hall is currently a Sr. Process Engineer at Genesis Engineers, Plymouth Meeting, PA.
