Silo Design And Selection
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…
Piping for Process Plants Part 1: The Basics
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…
Adiabatic-Temperature Rise: An Awkward Calculation Made Simple
Predicting an adiabatic-temperature rise is useful to chemical engineers for a number of purposes. One use is with combustion reactions whereby it is useful for determining the adiabatic-flame temperature. The adiabatic-temperature rise can be calculated for any reaction…
Damper Technologies for Regenerative Thermal Oxidizers
Regenerative thermal oxidizers (RTOs) are commonly used for controlling volatile organic compound (VOC) emissions from a broad spectrum of industries. An RTO is basically a thermal oxidizer that uses ceramic media as the heat exchanger medium, providing high…
Design Safer Solids Processing Plants
Chemicals, plastics, pharmaceutical, food, agricultural chemicals, coal and bio-chemical industries have a wide array of processes where the raw materials, intermediates and products are in particulate form. Hazards associated with particulate solids are unique, and in most cases…
Cartridge Filtration Principles For the CPI
Improvements in cartridge dirt-holding capacity has led to new designs, as well as to new equations for filter selection and specification, which are linked to dramatic improvements in the time between turnarounds and filter changeout. Cartridge filtration serves…
Assess Your Plant’s True Water-Savings Potential
For companies in the chemical process industries, water is an indispensable utility. But the growing scarcity of quality industrial water, combined with stricter environmental regulations and the rising cost of wastewater treatment, have encouraged the conservation of water…
Designing for A Safe Process
Accidents do happen. While not everything can be predicted, addressing safety concerns throughout the design of a process can help to prevent accidents from occurring. Designing with safety in mind can also help to minimize potentially serious consequences…
Troubleshooting Field Failures of Rupture Disks
Understanding why rupture disks fail can help ensure that they don’t Even with the best process design, the unexpected can happen. Anticipating this, rupture disks are often installed as the last line of defense against the over-pressurization of equipment used…
Factors Affecting Screening Performance
Consider these points when selecting and specifying equipment that separates material according to particle size Screening is an integral part of many dry material processes, ensuring an end product that is free of fine or oversized material, or in some…
