Producing a perfect batch is easy for some products but harder for others. Using analytics to dig into production data can help operators identify where variability might be creeping into a process For many batch manufacturers in the chemical process…
The ability to achieve an optimal steam balance can help to improve the overall thermal cycle efficiency of any steam-production system In any chemical process plant that produces steam, carrying out a steam balance is the most efficient way to…
Understanding boiler performance calculations can allow engineers to improve the operation of their facility’s steam system and better engage with boiler-system vendors Chemical plants, petroleum refineries, power plants and cogeneration systems use oil-and-gas-fired steam generators, fluid heaters and waste-heat boilers…
A general overview of industrial photochemistry and the design of large-scale stirred-tank photochemical reactors Photochemical processes complement or may even substitute conventional (thermal) processes. The radiant energy initiates the reaction, for example by forming radicals, and in most cases, no…
The activated sludge process (ASP) is designed to speed up the rate of decomposition of waste material in water. First developed in 1914, it remains an important means of treating both municipal and industrial wastewaters. This one-page reference provides information…
This column is based on “Propylene Oxide from Propylene and Chlorine – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/propylene-oxide-e11a. Propylene oxide (PO) is a highly reactive commodity compound that serves as a starting material…
Follow the guidance provided here to avoid many of the problems that can arise during the relocation of laboratory facilities The decision to move a laboratory from an existing space to a new research facility is often warranted. A merger…
Corrosion is an obvious factor to consider when selecting materials of construction for process equipment. However, the chemical environment of the process is only the starting point in selecting an acceptable material. A set of other factors can complicate corrosion-resistance…
There are many factors to consider when selecting a flare system for CPI sites that can impact safety, operating costs and environmental performance Flaring has long proven to be an effective technology for disposing of gases that cannot be used…
This column is based the report “LDPE via High-Pressure Tubular Process – Cost Analysis,” published by Intratec. It can be found at the following URL: www.intratec.us/analysis/ldpe-production-cost. Polyethylene (PE) is the world’s largest-volume commodity polymer, due in large part to the…
