Coal is milled and dried in preparation for gasification. The SERVOTOUGH Oxy 1900 1 and SERVOTOUGH SpectraExact 2500 2 provide percentage safety measurements for oxygen( O 2) and carbon monoxide( CO) to prevent combustion.

The milled coal is then gasified with steam( H 2O) to produce hydrogen( H 2), CO, carbon dioxide( CO 2) and methane( CH 4).

KEY APPLICATION TYPES:

The clean coal gas produced in the gasifying process is monitored for O 2 by the Oxy 1900 3, CO, CO 2 and CH 4 by the SpectraExact 2500 4 and H 2 by the SERVOPRO MonoExact TCD 5.

The CO is then converted into H 2 + CO 2 to raise the H 2 content, with the SpectraExact 2500 6 closely monitoring the CO level to optimize the process.

Methanol washing removes most of the CO 2 and sulfur, with the SpectraExact 2500 7 measuring CO and CO 2, and the MonoExact TCD 8 measuring H 2 to ensure gas components are present at the correct proportions.

Finally, the H 2 and CO are reacted to synthesize methanol, with the SpectraExact 2500 9 measuring the CH 4 to monitor the recycle gas.
