Design and Specification of A Compressed Air System

An industrial compressed-air system is expected to supply air of defined quality, required pressure and desired quantity to all the plant air and instrument air consumers. With air being one of the most critical utilities of a chemical plant, a…

This steam trap has scale removal capability

The LEX3N-TZ is a high-performance, temperature-control trap for steam service that has a built-in scale-removal function. An auger is built into the steam trap to remove scale and solids buildup from the valve seat during operation, preventing steam leakage and…

A new way to obtain hydrogen from heavy oil

The volume of heavy, sour crude oil processed by North American refineries is steadily increasing, and along with it a commensurate demand for hydrogen to upgrade that oil. A steam-reforming process that would allow refiners to produce their own H2…
