Process engineers understand how to harness the power of closed-loop multi-variable control in their plants. The evolution of digital control in the chemical process industries (CPI) has provided that power. Yet digital control represents just one facet of optimization and…
The need to conserve water is becoming a common concern throughout the world. Whether this is due to the cost of water, availability of water, or environmental concerns, water conservation is becoming a major focal point, both in the public…
Crystallization is a method of solid-fluid separation in which pure chemical crystals are formed. Crystallization kinetics consists of three major phenomena: nucleation (the birth of a crystal), transfer of the solute from the supersaturated solution to the crystal surface, and…
Today, companies in the chemical process industries (CPI) are faced with increased operating expenses, reductions in the number of qualified workers, strong competition and the need to do more with less. To meet these challenges, many companies are making use…
Each compressed air system is typically composed of one or more compressors with a power source, control system, intake air filter, after cooler and separator, air receiver, air dryer, interconnecting piping and a distribution system to deliver air to points…
There are many criteria that the engineer considers when optimizing: maximization of product yield or quality; minimization of recycle flow or energy consumption; and economic indicators, such as maximization of profits, net present worth (NPW) and minimization of payback period…
