In tower T2, T3, T4, T5, active principle is adsorbed by adsorbent, and gas not to be adsorbed etc. flows out from tower top, slow through second
Discharged after rushing the voltage stabilizing of tank 8.After absorption terminates, KV101, KV102 program-controlled valve on the absorption tower are closed.
2nd, it is suitable to put pressure reduction：Adsorbed state absorption tower T1 is completed, tower pressure interior force is equal to adsorptive pressure, the hydrocarbon worked off one's feeling vent one's spleen
Content is low, opens absorption tower along suitable put of decompression valve 11KV104a, regulating valve 17KC102, tower group is put and is depressured valve 16KV108,
Decompression processing is carried out to the absorption tower, discharges certain excess pressure, improves the concentration of hydrocarbon.After the completion of, close regulating valve
17KC102, tower group are suitable to put decompression valve 16KV108.
3rd, between absorption tower equal pressure drop and pressure rise a process：Adsorbed state absorption tower T1 is completed along after putting decompression, is also had in tower
Gases at high pressure, continue, along being put into out-of-bounds, hydro carbons can be taken out of, reduce gas recovery ratio, if being directly placed into suction port of compressor, hydrocarbon can be reduced
The concentration of class, increase follow-up heat exchange load；And it is in negative pressure state in the T6 of state absorption tower in vacuumizing, it is impossible to directly
Adsorbed.So pressing lift valve door 12KV105f between opening tower, state is vacuumized by being put into be in along the gases at high pressure after putting
In the T6 of absorption tower, so as to improve the concentration for completing hydrocarbon in adsorbed state absorption tower T1, taken out of with decompression gas and complete adsorption-like
State absorption tower T1 hydro carbons is continuing to adsorb in vacuumizing in the T6 of state absorption tower, improves the rate of recovery of hydro carbons.Complete
Suitable put in absorption tower is closed afterwards presses lift valve door 12KV105f between decompression valve 11KV104a, tower.
4th, it is vented process：Between absorption tower after the completion of equal pressure drop, complete to also have higher than normal pressure in adsorbed state absorption tower T1
Gas, opens absorption tower emptying valve 15KV107a, and gas is inversely discharged and takes some hydrocarbon out of, pressure is dropped into normal pressure, put
The adjusted valve 17KC103 of air body enters the first surge tank 4, finally by the cooled recovery of tubular heat exchanger 6.
5th, vacuum：After emptying process terminates, open and complete vacuum-pumping valve corresponding to adsorbed state absorption tower T1
14KV106a, vavuum pump 3 is opened, the desorbing gas being adsorbed in adsorbent is come out by vacuumizing mode, delivers to next ring
Section.
6th, final boost process：In after boosting terminates of state absorption tower T6 is vacuumized, absorption tower most final rise is opened
Pressure valve 10KV103f and regulating valve 17KC101, at the absorption tail gas introducing in adsorbed state absorption tower T2, T3, T4, T5
In vacuumizing in the T6 of state absorption tower, it will slowly be in and vacuumize in the T6 of state absorption tower boost in pressure to adsorptive pressure, etc.
Treat the absorption in next stage.
7th, Product recycling process：The gas mixture that vacuum is released first passes around the first surge tank 4 and carried out
Buffering, is then forced into 0.5MPa by compressor 5, then is cooled to 25 DEG C or so by tubular heat exchanger 6, by hydro carbons and water cooling
Liquid is congealed into, condensed mixture, oil water separator 7 is collected into and carries out stratification, remove moisture, opens valve 18, it is right
Product is recycled.
The organic gas processing unit based on absorption with pressure of the present invention, package unit are broadly divided into Adsorption and desorption, drying
Three links, absorption with pressure is carried out to tail gas first with NACF, decompression processing is carried out after adsorption saturation, when pressure is low
When steam pressure, steam desorption is carried out to the absorption tower 1, condensation separation recovery finally is carried out to stripping gas.Using adsorbing
Processing is dried in the absorption tower 1 that normal pressure qualified discharge gas caused by journey finishes to desorption, after drying, passes through the row of absorption
