The ever important aim of energy efficiency in the chemical process industries (CPI) is brought closer to its target by the practice of energy recovery in heat exchanger networks (HENs). When heat exchangers are designed to work together to exchange heat between hot and cold streams, the required utilities are effectively reduced. The HEN designer usually applies the assumptions of fixed operating...

The Witte Co. This salt-drying system recycles hot exhaust air Among a host of advantages, the bulk salt-dryer system (photo) from this company captures half of its hot exhaust air for recycling, which both reduces energy requirements and cuts the volume of exhausted air. Designed for drying road salt, rock salt, sea salt, food-grade table salt and other salt products, the system combines a vibrating bed...

Water systems are common in the chemical process industries (CPI). Mixing, heating, concentrating and evaporating water in these systems will often result in an accumulation of inorganic scale, which can markedly decrease process-system efficiency. Scale inhibitors are chemical substances that, when added to industrial water at very low levels, act to reduce or prevent the formation of scale. Over the past...

Manufacturers of specialty chemicals are routinely required to reduce costs and increase the production of their high-value products. Specifically, competitive pressures from the developing world, increases in raw material costs and volatility in energy costs are putting significant pressure on manufacturers to minimize processing costs and maximize product yields. The economic impact of optimization...

Many individuals and organizations have made important contributions to the creation of inherently safer (IS) products, processes and process plants [1–3]. A brief survey of successful case histories shows that most reported applications relied on only a few of the core IS principles. This paper emphasizes the opportunities presented by three particular — and often-overlooked —...

A variety of factors — including a shift in the median age of workers worldwide and the impending skills shortage due to attrition and early retirements — have created a need to find fast and reliable methods and tools for mapping the technical competencies of professionals in the chemical process industries (CPI). Typically competency-mapping projects in the CPI begin with some form of task or...

Traditionally, most students have learned about chemical reactions in laboratories using test tubes, beakers and flasks. Those who have gone on to discover and develop new products have typically done so using these batchwise techniques. This mind-set has continued through the piloting and scaleup phase, so that today, many chemical products are produced batchwise in large, continuously stirred reactors...

This book examines global patent law as it affects the chemical, biological and pharmaceutical industries. Rather than taking a legal case-study approach, it provides a practical discussion of everyday issues and decisions faced by global patent practitioners in these complex industry segments. Focusing mainly on the patent systems in the U.S., U.K. and Japan, the five-section book effectively summarizes...
