Summary: | The invention relates to a method for depriving hydrogen sulfide from sulfur-containing oil well products. A one-stage gas-liquid separation and two-stage subpressure flash vaporization method is adopted to deprive the well products, i.e. crude oil, natural gas, hydrogen-sulfide-containing natural gas in water and hydrogen sulfide dissolved in the crude oil and the water. According to the method, the deprivation ratio of the hydrogen sulfide in the crude oil and the water reaches over 95% through optimizing the operating pressures and the temperature parameters of subpressure flash vaporization towers. |
