A well designed and operated heat-transfer-fluid system is a key feature of a safe, reliable and cost-effective heating design. However, problems can arise if the heat-transfer fluid becomes heavily degraded or the system is allowed to accumulate solids and other…
Gas-liquid reactors in the chemical process industries (CPI) have increasingly been designed to handle larger manufacturing scales. Since gas-liquid reactors can represent substantial capital and operating costs for the user, optimizing mixing and maximizing productivity are critical. The need for…
Reciprocating pumps are often used in the chemical process industries (CPI) because of their ability to generate high pressures at low velocities. A subcategory of positive-displacement pumps, reciprocating pumps act through the recipricating motion of a piston, plunger or diaphragm.…
Storing solid materials in hoppers, bins and silos is ubiquitous in the chemical process industries (CPI), as are challenges associated with dispensing them. In many cases, using vessels with steep cones and smooth walls is enough to provide reliable flow.…
Contact-based temperature sensors, such as thermocouples and resistance temperature detectors (RTDs), have demonstrated accurate and cost-effective operation throughout the chemical process industries (CPI). However, there are many applications and settings where they are simply not practical. In those cases, engineers…
The precise monitoring and control of valve position is essential for efficient automation of both discrete and continuous processes. Measurement of valve position provides the data required for the use of advanced control strategies and predictive maintenance algorithms. More effective…
In recent years, a number of factors have further emphasized the importance of solvent selection in the chemical process industries (CPI). These include the increasing regulatory scrutiny leveled on industrial solvents, and an effort by CPI companies to reduce the…
Most of the more than $100 billion in capital spending and $1.2 trillion in prodution costs spent annually by the chemical process industries (CPI) is committed by decisions made in the early phases of process development and plant design. A…
Measurement of fluids’ viscosity in the chemical process industries (CPI) can represent a useful “product dimension” for manufacturers. Understanding a material’s flow characteristics is valuable in predicting several parameters relevant to many CPI processes, including pumpability, pourability, performance in a…
Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time and highly specialized crystallizer designs have been developed, especially in long-established industries. Solution crystallization is an…
