Problems solved by technology
[0004] The purpose of the present invention is: in order to solve the problem that the existing associated gas recovery process does not strictly carry out gas-liquid separation before desulfurization, and most of the existing associated gas recovery processes use desulfurization towers for desulfurization, and the desulfurization effect is not good. Provide Recovery method of associated gas on offshore oil production platform

The invention discloses an offshore oil production platform associated gas recovery method, and relates to the field of associated gas recovery, and the method comprises the following steps: step 1, purification: connecting an associated gas recovery pipeline with a preprocessing bin, and after preprocessing is completed, enabling the associated gas to enter an impurity removal bin for impurity removal; and 2, dehydration: removing impurities from the associated gas, and dehydrating the associated gas through a pre-separation pipe, a cooler, a low-pressure separation pipe, a supersonic vortexseparator and a pressurizing pipe. According to the invention, the pre-separation pipe, the cooler, the low-pressure separation pipe, the supersonic vortex separator and the pressurizing pipe are arranged; the associated gas can be subjected to gas-liquid separation before entering a desulfurizing tower; the impurities and oil stains in the associated gas are separated step by step, then water vapor in the associated gas is separated, and the supersonic vortex separator is mainly adopted, so that the water vapor separation effect is better, a desulfurizing agent is prevented from being blockedduring later desulfurization, and the desulfurization effect is better.
Description
technical field [0001] The invention relates to the field of associated gas recovery, in particular to a method for recovering associated gas on an offshore oil production platform. Background technique [0002] Associated gas, usually refers to the natural gas that coexists with petroleum. According to the oil generation theory of organic hydrocarbon formation, the evolution of organic matter can generate liquid hydrocarbons and gaseous hydrocarbons. The gaseous hydrocarbons are either dissolved in liquid hydrocarbons, or exist in the upper part of the oil and gas reservoir in the state of gas cap , These two gaseous hydrocarbons are called oilfield associated gas or associated gas. From the perspective of oil recovery, it refers to the natural gas produced when oil fields or oil reservoirs are exploited. [0003] Desulfurization is required in the existing associated gas recovery process, but the existing associated gas recovery does not strictly separate the gas and liqui...
