Propylene Production via Propane Dehydrogenation

Propylene is the second most important intermediate in the petrochemical industry after ethylene, and its global demand is dominated by the production of polypropylene. However, the growing use of natural gas from shale deposits as a raw material for steam…

Pressure-Vessel Quality Control Requirements

Pressure vessels are common in the chemical process industries (CPI) and they range widely in size and complexity. Process engineers may be tasked with inspecting a new pressure vessel or with witnessing hydrostatic testing of a vessel. In addition, engineers…

Pressurized Piping: Sampling Steam and Water

Corrosion and deposition in boilers, steam turbines and many types of process equipment are among the most expensive causes of outages in utility and industrial steam plants. Deposits and scale buildup on heat-transfer surfaces reduce efficiency, and when allowed to…

Dust Hazards

Dust is a critical consideration in the chemical process industries (CPI) from both a process safety standpoint — as a potential fire and explosion hazard — and from an occupational safety standpoint — as a potential worker exposure hazard. Reinforcing…

Remote Thermal Sensing

By making it easy to detect heat anomalies, thermal cameras and infrared thermometers support preventive and predictive maintenance Rising temperatures and rapid or excessive heat buildup are useful markers for determining the operational health of many types of machinery and…

Filtration Testing and Slurry Conditioning

Testing in filtration processes is critical for determining the properties of solids being filtered and the ease or difficulty of the filtration. In addition, laboratory testing is important in specifying filter media, filter aids, filter area, cake space needed and…

Plant Revamps and Turnarounds: Some Lessons Learned

A plant turnaround is always challenging in the chemical process industries (CPI). But with proper planning and reliable procedures in place, last-minute time crunches and failures can be prevented. When haste combines with faulty methods, costly problems result. This article…

Butene via Ethylene Dimerization

Olefin dimerization is a reaction where two molecules of a monomer combine to form a dimer. It can be utilized to produce normal butenes from ethylene, which can be provided by a steam cracker. Dimerization of ethylene is generally applied…

The Globally Harmonized System

When the U.S. Occupational Safety and Health Administration (OSHA) revised the U.S. Hazard Communication Law, U.S. 29 CFR 1910.1200, in May of 2012, it set off an avalanche of change in the environmental, health and safety (EH&S) circles of American…
