With typical operations running around the clock, the chemical process industry (CPI) demands high performance from its instrumentation. Today's flowmetering solutions include tools for the entire life cycle of a flowmeter. From engineering, commissioning and start up to…
Occupational dangers in the chemical process industries (CPI) are many, with falls, respiratory hazards, and explosion risks confronted daily. One hazard, however, causes no pain nor visible scars. Its effects accumulate with each overexposure and can go unnoticed,…
The use of shell-and-tube heat exchangers is widespread in the chemical process industries (CPI). In applications where contact between shell- and tube-side fluids is not tolerable, it is important for the engineer to understand some of the design…
The pressures and challenges placed on the chemical process industries (CPI) have been heralded so often that even a person on the street can articulate most of them; and the list continues to grow - cost containment, lawsuits,…
Pipe flanges are used to mechanically connect pipe sections to other pipe sections, inline components, and equipment. Flanges also allow pipe to be assembled and disassembled without cutting or welding, which eliminates the need for those two operations when…
Spend the necessary time on unit status evaluation and onsite work preparation for optimum return on investment and payback period The preparation of a unit for restart requires complex and systematic approach. A plant restart project is traditionally composed of…
With energy costs rising, the value of most powders and bulk solids has been rising steadily as well, giving manufacturers ample reason to improve production efficiency. "Companies not only want to reduce their consumption of power, they also…
Why do governmental bodies regulate VOC (volatile organic compounds) emissions? Because these compounds react with nitrogen oxides to produce ground-level ozone. VOC emissions have many names: hazardous air pollutants (HAPs), non-condensable gases (NCGs), or just plain “organic vapors.”…
There are a variety of reasons to consider the purchase of a new tank or silo1. As organizations grow, so does the need for increased storage capacity. Meanwhile, an old tank may become corroded or worn and require…
This is the first in a series of articles that will cover a wide range of piping topics. The topics will cross process-industry lines, pertaining to, for example, the chemical, petroleum-refining, pulp-and-paper and pharmaceutical and other industries.The main…
