Influence product quality pre- cut, by control pre-rectifying tower backflash liquid level by influence product quality pre- cut swim in liquid
Face upper strata is produced by overflow line.
The extraction tank of this reality application is arranged on three layers of rectifying framework, by controlling pre-rectifying tower tower top methanol steam temperature to exist
40 DEG C or so so as to by most light components（Dimethyl ether, acetaldehyde, acetone etc.）Removing is clean, and the light component of only a few passes through again
Extraction tank addition extraction water is extracted, and the pre- cut of influence product quality swims in liquid level upper strata and produced by overflow line.
Purification is gone to be vented by the fixed gas after pre-rectifying tower condenser B.
Letdown tank is used for the cut of miscellaneous equipment in collection system, is not present invention point, excessive elaboration is not done.
This programme will influence the pre- cut of pre-rectifying tower, the recovery tower of methanol product quality by setting fusel oil sump tank
Fusel oil etc., which is collected separately, delivers to fusel oil sump tank, and other anti-surge coolers condensation methanol and servicing motor-pump discharge methanol are still
So collect and carry out rectifying again in underground tank, methanol production is improved to greatest extent in the case where meeting product quality so as to reach
Amount reduction consumption, can ensure that product quality adds yield again.
