There are many differences between gas detection systems used for process monitoring and those used for protecting the safety of personnel Some types of gas detectors keep an eye on production processes. Others, relying on a number of different technologies,…
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…
A thorough understanding of enclosed combustion technologies will help engineers to select the proper equipment to balance emissions-control performance with efficiency, costs and complexity Selection of an enclosed combustion solution is a complex process that involves various environmental and operational…
Development of robust preparation and response procedures can help chemical plants to weather disaster events and return to normal operations in a safe and efficient manner Having a well-defined and understood approach to disaster preparation and response will ensure that…
With proper planning, spills can be managed properly and the risk of secondary events — which may be more dangerous and costly — can be reduced Spills are probably one of the biggest problems any laboratory or pilot plant operation…
Chemical engineers bring many essential skills to the diverse teams required for successful control room design In any continuous manufacturing plant in the chemical process industries (CPI), engineers need to consider control room architecture and design as part of their…
In order to correctly size pressure relief valves (PRVs), a robust understanding of discharge coefficients for vapor, liquid and two-phase flow is crucial A pressure relief valve (PRV) is used to prevent the pressure in a process vessel from exceeding…
Compliance with air-pollution regulations requires ongoing effort. Follow these recommendations to assess competing options and optimize system design while minimizing cost and risk The goal of air-pollution control (APC) is to limit the amount of pollutants entering the environment. These…
The numerous flame sources in CPI facilities necessitate the installation of advanced flame-detection technologies Fire is a primary and very real threat to people, equipment and facilities in the chemical process industries (CPI), especially in the refining and storage of…
Activated sludge processes are inherently complex. Proper system design, operation and maintenance are essential to adequately break down target organic materials Since its discovery more than 100 years ago in 1914 by Ardern and Lockett [ 1 ], the activated…
