As technologies advance and market challenges continue to pose new pressures for operators, the decommissioning and retrofitting of facilities is inevitable. This article provides guidance on how to tackle projects of this nature safely and efficiently As with many industrial…
Agglomeration and granulation are used to achieve a wide range of objectives in solids-handling processes, including to ensure a desired particle-size distribution, minimize segregation, and improve solids flow, as well as to control de-aeration and compaction behavior and attrition resistance…
The size and size distribution of particles are important determining factors in the design and operation of many process operations involving dry particles and powders. Follow this guidance to understand the impact of these key characteristics Bulk solids are dry…
The relationship between valve selection and safety certification still causes confusion. A focus on functional safety can help to elucidate Among the many varied viewpoints on the topic of emergency shutdown (ESD) valves, there are several aspects that continue to…
General guidelines for selecting the appropriate power-plant cooling system are presented here The main purpose of a power plant is to convert a source of energy into electric power. Most power plants rely on heat as the energy source (thermal…
This column is based on “Calcium Hypochlorite Production via Sodium Method – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/calcium-hypochlorite-production-cost. Calcium hypochlorite, Ca(OCl)2, is among the few metal hypochlorites that is stable enough to be…
Cake filtration is a common operation across many sectors of the chemical process industries (CPI). In cake filtration, the solid being filtered acts as a screen so that particles of the suspension are retained by the medium, resulting in the…
Stonchem 444 is a spray-applied vertical lining system (photo) formulated to resist corrosion and abrasion and protect underlying substrates from a broad range of chemicals, including most petroleum-based products, salts, acids and alkalis. Approved for potable water storage tanks of…
