Proper gas sampling is essential to meet operating and regulatory objectives Flares are used extensively in chemical process industries (CPI) facilities and petroleum refineries, to combust flammable hazardous gases. When designed and operated properly, they provide a proven mechanism to…
Mixing and blending of bulk solids is common in pharmaceutical and food manufacturing, specialty chemicals, explosives, fertilizers, glass and ceramics, detergents and resin industries. This column provides information on batch versus continuous blending mechanisms. Batch versus continuous Batch blending processes…
This column is based on “MTBE production from Raffinate-1 - Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/mtbe-production-cost. Methyl tertiary-butyl ether (MTBE) is an organic compound used mainly as a fuel additive to enhance octane…
Plant layout is as important a part of process plant design as it ever was, but it is rarely taught as part of chemical engineering courses While process plant layout is a critical aspect of chemical process industries (CPI) operations,…
Be vigilant about parallel pumping conditions that can lead to catastrophic failures During my career, I have seen several massive centrifugal pump failures caused by pump users attempting to operate pumps in parallel without the proper equipment review, procedural review…
Whether to remove solid contaminants from a liquid or separate a solid product from a solvent, solid-liquid (S-L) separation is a common unit operation across the chemical process industries (CPI). This one-page reference provides an overview of S-L separation methods,…
A better understanding of what pressure instruments do and how they work can help improve measurement performance, especially in troublesome applications Effective use of process instrumentation is critical in any chemical manufacturing environment. These instruments are strategically located throughout various…
Users should consider both options when selecting a DP device. Understanding the differences can help make the decision for a given set of process conditions Differential pressure (DP) measurements are used in many branches of the chemical process industries (CPI)…
This column is based on a report published by Intratec titled “Carbon Fiber Production from Pitch — Cost Analysis.” The report can be found at: www.intratec.us/analysis/carbon-fiber-production-cost. Carbon fibers (CF) are defined as fibers containing at least 90% carbon by weight,…
Dust management can be divided into three main categories: prevention, containment and suppression. Understanding the key considerations for each can help bulk solids handlers arrive at an optimal dust control solution Dust management is an ongoing issue faced by virtually…
