As level is a critical parameter for those in the chemical process industries (CPI), level measurement instrumentation has been around for some time. But as processors scramble to become more efficient, reduce waste, control inventory and abide by environmental regulations, level measurement has become even more important. As a result, device manufacturers are improving existing technologies with...

Chemicals in production and laboratory environments alike have three distinct lifecycle phases: the first is procurement and inventory storage; the second is use in a manufacturing process or research program; and the third is post-use, including onsite handling, removal and beneficial reuse, recycle or disposal. A number of considerations including regulations, safety, material utilization efficiency...

Reciprocating compressors — the most commonly used type of compressor throughout the chemical process industries (CPI) — are flexible and efficient, and they can generate high head (from several bar to several thousand bar) independent of gas density. Worldwide, the installed reciprocating compressor horsepower is approximately two times that of centrifugal compressors. However, the maintenance...
