Selecting personal protective equipment (PPE), including safety eyewear, for the chemical process industries (CPI) depends on the hazards present in the facility where it is used. The following describes considerations for selecting eye and face protection based on the potential…
Contracting a pilot plant is a viable approach for any organization. However, it can be fraught with potential issues, which need to be understood and addressed in advance Reduced in-house resources have limited the options many organizations have for designing…
Controlling the temperature of a process using a thermal loop is important in many applications. The importance of a power controller is discussed here For any process where temperature needs to be monitored or controlled, a thermal loop is required.…
Vinyl acetate (also known as vinyl acetate monomer; VAM) is important in the manufacture of many polymers and resins. The greatest demand for vinyl acetate is associated with the production of polymers and copolymers, mainly poly(vinyl acetates) used in papermaking,…
Perfluorinated ion-exchange membranes are developing beyond legacy applications to find use in a wide variety of emerging markets, including renewable energy Ion-exchange membranes are used in numerous industrial processes, including seawater desalination, electrodialysis and the production of commodity chemicals via…
In some situations, it might be necessary to remove or replace a bolt during operation. This article shows how to determine the proper bolt load to prevent leaks Bolted flange joints (Figure 1) are part of pressure vessel and piping…
Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…
Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…
Linear alpha olefins (LAOs) are hydrocarbons with the chemical formula CnH2n, characterized by linear chains and one double bond at the alpha position (Figure 1). Such hydrocarbons are important chemical intermediates, widely used in several industrial and consumer products according…
Storage tanks containing hazardous materials require safety instrumented systems (SIS) to prevent overfills. Digital technology in the latest level-measurement devices used in SIS enables remote proof-testing, which provides significant advantages At industrial facilities with tanks containing hazardous, flammable or explosive…
