Problems solved by technology

However, since hydrogen sulfide is soluble in water and insoluble in organic matter, when encountering heavy oil production and oil transportation, due to the high viscosity of heavy oil, poor fluidity and wrapping effect, a large amount of hydrogen sulfide exists in heavy oil Inside, this causes hydrogen sulfide to escape from the wrapped heavy oil again in the process of oil extraction, oil transportation and oil refining, and its high toxicity will pose a threat to the staff and seriously pollute the environment

Abstract

The invention relates to a method for removing hydrogen sulfide from thickened oil. According to the technical scheme, one end of an emulsifier is connected with an oil conveying pipeline, the other end of the emulsifier is connected with an oil-water gravitation flow separator, the lower portion of the liquid outlet end of the oil-water gravitation flow separator is connected with a reactor liquid inlet pump through a reactor liquid inlet pipeline, and the reactor liquid inlet pump is connected to a chemical reactor through a negative pressure ejector; the chemical reactor is connected to a precipitation filter through a transition connecting pipe, and the precipitation filter is connected into the emulsifier through a liquid outlet circulating pipeline and a reaction circulating pump; the method has the beneficial effects that a mixture of thickened oil and water can be emulsified, hydrogen sulfide wrapped in the thickened oil is dissolved in the water while emulsification is conducted, then the water containing hydrogen sulfide is led out of the chemical reactor through an oil-water gravity flow separator to react, and ferric salt and elemental sulfur which are generated throughthe reaction of hydrogen sulfide are filtered and removed; in addition, the implementation space is large, the device can be installed on one side of a gathering and transportation station or a fieldoil transportation pipeline, and the process application is convenient.

Description

technical field [0001] The invention relates to a device and method for removing hydrogen sulfide, in particular to a method for removing hydrogen sulfide from heavy oil. Background technique [0002] In the process of oil extraction, the hazard of hydrogen sulfide is accompanied by the whole process of oil extraction and exploitation. However, with the deepening of oil extraction, there are more and more wells containing hydrogen sulfide. Therefore, the work of preventing hydrogen sulfide and eliminating hydrogen sulfide, no matter It is very important in oil recovery, oil transportation and oil refining process. For example, in the gathering and transportation of oil, the extracted oil is transported to the general gathering and transportation station through the gathering and transportation pipeline, and then transported from the gathering and transportation station to the refinery for processing, and then produces gasoline, diesel, chemical products, etc. However, in oi...
