天然气胺法脱硫过程中的溶剂发泡防治方法与装置
摘要：
本发明涉及天然气胺法脱硫过程中的溶剂发泡防治方法与装置，提供了一种天然气胺法脱硫过程中的溶剂发泡防治方法，该方法包括：(a)在原料天然气进入硫化氢吸收塔中与脱硫溶剂接触之前，采用气-液微旋流分离技术除去原料天然气中夹带的固体微粒杂质和C4及以上的重质烃，得到净化天然气；(b)在净化天然气离开硫化氢吸收塔前，采用气-液微旋流分离技术将净化天然气中夹带的溶剂回收。本发明还提供了一种天然气胺法脱硫过程中的溶剂发泡防治装置。
摘要（英）：

The invention provides a solvent foaming control method in an amine desulfuration process of natural gas, and relates to a solvent foaming control method and device in the amine desulfuration process of natural gas. The method comprises the steps that (a), before raw natural gas enters a hydrogen sulfide absorption tower and is contacted with a desulfuration solvent, solid particulate impurities, C4 and above heavy hydrocarbons entrained in the raw natural gas are removed by a gas-liquid micro hydrocyclone separation technology, and purified natural gas is obtained, and (b), before the purified natural gas leaves the hydrogen sulfide absorption tower, a solvent entrained in the purified natural gas is recovered by the gas-liquid micro hydrocyclone separation technology. The invention also provides a solvent foaming control device in the amine desulfuration process of the natural gas.
