CN106810414A Chinese invention patent application《A kind of isooctane production line》A kind of production system is disclosed, it includes cryogen
It is pump, raw material surge tank, depropanizing tower, return tank, dehydrator, reactor, flash tank, pickling expansion chamber, alkali cleaning expansion chamber, de- different
Butane tower and de- normal butane tower, raw material surge tank include ladle bowl and a component dividing plate, in above-mentioned production system, one in surge tank
The time that component dividing plate increase gas flows in surge tank, liquefaction efficiency is improved, spherical demarcation strip is separated into tank body up and down
Two parts, spherical demarcation strip increase mixed gas and the contact area of condensing agent, improve cooling effect, are flashed by changing
The area and time of pot liquid and air contact improve flash evaporation effect.
However, industrialization isooctane device is generally used as catalyst using the concentrated sulfuric acid at present, it is useless caused by reaction system
Acid needs continuous discharge, while supplements fresh acid, to ensure sulfuric acid concentration.The spent acid of discharge delivers to spent acid storage tank after processing
Storage, pressure inside the tank is controlled by tank deck Self force valve.Although spent acid before sending outside by processing, with remove hydro carbons therein and
SO2Deng impurity, but still there is a small amount of SO after placement for a long time2Separated out Deng sour gas, air is directly discharged into from tank deck Self force valve
In.Especially in spent acid processing system exception, the SO of release2The corruption of peripheral facility more, can be not only exacerbated Deng sour gas
Speed is lost, and environment is polluted.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, there is provided one kind can reduce periphery and set
