Liquid separates, and adjusts gas temperature by corresponding heat exchanger；
3. controlling first class purification liquid temperature degree and alkalescence, ensure to be ensured in temperature by the liquid gas that level-one liquefied room comes out
It is down to -4-4 DEG C；
4. -40-80 DEG C of second level scavenging solution is atomization in the second reative cell of second level purifier, afterwards will be upper
State gas to be passed into second reative cell, C3 gas liquefactions；
Mixed gas is behind first class purification room and level-one gas-liquid separation device, water and water-soluble gas impurity and part height
The hydro carbons of boiling point is down to -4-4 DEG C by isolation of purified, temperature.Two level using cold liquid spray, control microlayer model in seal cavity with
Mixed gas is sufficiently mixed heat exchange, controls in gas liquid ratio 1:2--1:10, larger heat exchange specific area is big, and heat exchange efficiency is very high,
When gas temperature is reduced to -60 DEG C or so, the gas liquefaction such as C3, a variety of lighter hydrocarbons are absorbed.
5. by the gas-liquid separation device in the purifier of the second level to through the second reative cell purified gas into promoting the circulation of qi
Liquid/gas separator, and gas temperature is adjusted by corresponding heat exchanger.
In an optional embodiment, above-mentioned spraying device preferably uses gate-type spray chamber as shown in Figure 2, ensures
360 ° of square sprayings are very contacted with intake air；Meanwhile liquid pipe and the overflow port of first order reaction room connection are (while with one
The liquid level of level scavenging solution) ensure in sustained height.
It should be noted that above-mentioned second level purifier includes second order reaction room, two are loaded with the reative cell
Level scavenging solution, and be equipped with secondary purification liquid in the atomization spraying device of reative cell.Second be atomized in second reative cell
