COAL TO METHANOL
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 .
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 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.
The milled coal is then gasified with steam
(H 2 O) to produce hydrogen (H 2 ), CO,
carbon dioxide (CO 2 ) and methane (CH 4 ).
METHANOL TO OLEFINS
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. Methanol is converted into methylene
and ethylene glycol (MEG), then
cracked to produce olefins under high
temperature. The crystalline catalyst must
be regenerated regularly, so an optimized
gas regeneration process is crucial.
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. The Oxy 1900 1 provides O 2
measurements while, depending on
individual suitability, the SpectraExact
2500 or SERVOTOUGH LaserSP 2930 2
can monitor CO or CO 2 , or the
SERVOTOUGH Laser 3 Plus for CO.
The olefins are dried and separated to
produce products including ethylene
and propylene.

separation tower, the revolutionary
