Today, validation is no longer an afterthought for the design and construction of a new or renovated process or facility. It is, in fact, recognized as an integral part of the total project. Fully integrated services are now available to ensure a...
Search firms and executive recruiters can be powerful allies in a competitive employment environment.This article puts their role in context and provides guidelines on how to work effectively with them.
Efficient and reliable pumps can significantly improve a plant’s bottom line. This article reviews important concepts that a chemical engineer must understand and the factors that need to be considered when selecting radial-flow centrifugal pumps.
In a petroleum refinery, viewing hydrogen as an asset rather than a liability can lead to increased profits. The key is in the mindset. A typical investor uses money to make money. This article shows you how to use hydrogen to make money.
Although the sparsity of effects principle is still good advice, we need to be careful of emphasizing it too much -- to the point that it becomes an assumed practice, rather than a useful rule of thumb.

Proper design and scaleup of a membrane filtration system requires an understanding of the availability of membrane material, pore size and module configurations. These practical guidelines will help in the selection process.
Sustainability encompasses green chemistry and green engineering, among other concepts. This article explores some of the principles of sustainability and provides a framework for developing a lifecycle approach to chemical engineering.
Most chemical engineering curricula do not adequately address mixing as it is commonly practiced in the chemical process industries. This article attempts to fill in the gaps by explaining flow patterns, mixing techniques, and the turbulent,...
Finding the throughput of a multiple-unit, multiple-step operation, even when it is relatively uncomplicated, is not always an easy matter. Several equations and graphical aids are provided to help determine yearly capacity.
If your plant's utility system is experiencing problems, the culprit may be the clarifier. Understanding how to diagnose and correct off-spec clarifier operation will allow downstream units to function more efficiently and reliably.
Work-style and communication differences often result in a disconnect between managers and engineers. Bridging this culture gap will allow managers to make better business decisions and bring engineers the understanding and recognition they deserve.
The production of stem-cell-based therapeutic products in large quantities is more complex than manufacturing molecular drugs. Scale-up and scale-out challenges arise related to the type of stem cell, cell expansion and banking, sterile handling,...
Build safety into your process by substituting less-hazardous materials and chemistry, minimizing inventories and equipment sizes, moderating operating conditions, and simplifying unnecessarily complex operations.
The keys to building a talented workforce: benefits that enable employees to balance their work and personal lives; stimulating and challenging assignments; and a culture that allows all employees to reach their full potential.
Changing maintenance and/or operating procedures can significantly increase cooling tower performance without major capital expenditures. Here are some tips for ensuring proper design and operation of major tower components.
This is the time of year when thousands of undergraduates are completing their degrees and beginning their careers and chemical engineers. As I travel to chemical engineering schools to attend AIChE's spring regional student conferences, the...
This method uses a numerical solution to the McCabe-Thiele diagram to find the theoretical number of stages for binary and pseudo-binary systems,then calculates the actual number of stages, reflux ratio and column dimensions.
