Particulate buildup and other material flow problems are common hurdles wherever dry materials find application in the chemical process industries (CPI). Since manual intervention is costly in terms of downtime, and can be quite hazardous for the personnel involved, dedicated…
Pipe sizing calculations include certain values that are time dependent, such as costs. While some costs rise, others decrease over time. It is the designers task to ensure that the total cost is minimized. For fluid flow calculations, heuristic criteria…
The chemical process industries (CPI) invest large amounts of capital each year and spend even more to produce the goods they sell. In 2007, CPI companies large enough to be in the Fortune 500 list invested more than $100 billion…
Typical wastewater-treatment plants (WWTP) — both industrial and municipal — consume large amounts of energy, which can represent 50% or more of the facility’s variable operating and maintenance costs. Most employ biological processes that rely on energy-intensive aeration systems whose…
Relief system design is an important engineering activity throughout the chemical process industries (CPI). The main purpose of this task is to design a system that protects process equipment and piping against all possible causes of overpressure. It should relieve…
As bulk-solids processors look for ways to save money, manufacturers of screening equipment are concentrating on maximizing the efficiency of the equipment they offer. Screening has been prominent in solid-solid separations in the chemical process industries (CPI) for decades. It is…
Faced with increased workloads and time and budget constraints that often restrict external training support, many chemical process operators are forced to get the most out of their heat transfer system with less help. This article offers recommendations for how…
