Abstract
The invention relates to a method for recovering tail gas methanol in thioether rectification. A gas-state discharge pipeline after a thioether rectification tower condenser is provided with a cyclone separator, part of gas-state or vaporous methanol enters the cyclone separator along with tail gas flow, and the vaporous methanol is thrown to the separator wall under the action of the cyclone separator; the vaporous methanol contacts the separator wall, enters a liquid discharge pipe to be separated out, and is recovered to a methanol storage tank; and the unseparable gas-state part is discharged from the top of the cyclone separator, and enters a tail gas treatment system to be treated. The method provided by the invention is used for recovering methanol in the thioether rectification technique, and can save the resources.
Description
Technical field
The method of tail gas Methanol Recovery in a kind of thioether rectifying of the present invention.
Background technology
Utilizing methyl alcohol and carbon disulphide production thioether, and carry out in azeotropic distillation process to thioether, the vaporific methyl alcohol of part and gaseous state tail gas can together be taken as vent gas treatment and fall after overhead condenser process, cannot reclaim, cause the wasting of resources aborning to methyl alcohol.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for tail gas Methanol Recovery in a kind of thioether rectifying, reclaims the methyl alcohol in technique in thioether rectifying, economizes on resources.
Above-mentioned purpose of the present invention is realized by such technical scheme: a kind of method of tail gas Methanol Recovery in thioether rectifying, comprises the following steps:
Step one: the delivery pipe after thioether rectifying tower condenser arranges cyclonic separator, exhaust temperature after condenser is lower, part gaseous state or vaporific methyl alcohol enter cyclonic separator with exhaust gas flow, and under cyclonic separator effect, vaporific methyl alcohol gets rid of to wall.Step 2: vaporific methyl alcohol contacts with wall, just loses mass force, and lean on the momentum of inlet velocity and downward gravity to fall along wall, thus be separated, be then recovered to methanol tank; The gaseous parts that cannot be separated, from cyclonic separator top discharge, enters exhaust treatment system process; Tail gas Methanol Recovery in thioether rectifying is completed by above-mentioned steps.
Described cyclone inlet is connected with condenser exhaust emissions pipeline, and cyclonic separator leakage fluid dram is connected with methanol tank, and visor installed by cyclonic separator, and be convenient to observe, the venting port of cyclonic separator is connected with exhaust treatment system.
In a kind of thioether rectifying of the present invention, the method for tail gas Methanol Recovery, for reclaiming the methyl alcohol in thioether rectifying in technique, economizes on resources.
Embodiment
A method for tail gas Methanol Recovery in thioether rectifying, comprises the following steps:
Gaseous exhaust pipeline after thioether rectifying tower condenser arranges cyclonic separator.Cyclone inlet is connected with condenser exhaust emissions pipeline, and the leakage fluid dram of cyclonic separator is connected with methanol tank, and visor installed by cyclonic separator, is convenient to observe.The venting port of cyclonic separator is connected with exhaust treatment system.Exhaust temperature after condenser is lower, and part gaseous state or vaporific methyl alcohol enter cyclonic separator with exhaust gas flow, and under cyclonic separator effect, vaporific methyl alcohol gets rid of to wall.Vaporific methyl alcohol contacts with wall, just loses mass force and leans on the momentum of inlet velocity and downward gravity to fall along wall, entering liquid discharge pipe, thus be separated, be then recovered to methanol tank; The gaseous parts that cannot be separated, from cyclonic separator top discharge, enters exhaust treatment system process, completes tail gas Methanol Recovery in thioether rectifying.
Claims (1)
1. the method for tail gas Methanol Recovery in thioether rectifying, is characterized in that comprising the following steps:
