Process Analytics Water Detection in Liquid Gas
“We developed the Processlab Gas Analyzer specifically to determine water content,” explained Jochen Schäfer, Marketing & Sales Support Business Unit Manager at Deutsche Metrohm.
Water content is a critical parameter which determines the quality of liquid gas. “We developed the Processlab Gas Analyzer specifically to determine water content,” explained Jochen Schäfer, Marketing & Sales Support Business Unit Manager at Deutsche Metrohm. Rugged design, ease of use, Tiamo control and database software, and strict separation between the gas handling system and the electronics are some of the impressive features of the system.
The Karl Fischer coulometer makes it possible to detect trace levels of water. The system is designed for a maximum pressure of 40 bar. Besides a built-in evaporator for liquid gas, the system also has an oil filter and an inlet filter to keep out particulate matter. A mass flow controller is used for precision measurement of the gas stream. Software-controlled magnetic valves ensure fully automatic operation.
The analyzer is supplied with predefined software methods. Typical applications include the detection of water content in propane, propene, LPG, butane, butene, ethylene oxide and dimethyl ether. The analyzer can also be used to detect water content in permanent gas and other liquid gas.
