Description
Technical field
The utility model relates to a kind of device using in petroleum production engineering field, relates in particular to a kind of utility unit of removing pernicious gas hydrogen sulfide in oil well associated gas.
Background technology
As everyone knows, hydrogen sulfide (H
2s) harm of gas is very large, and in environment, hydrogen sulfide reaches certain concentration, and the lighter makes eye blind, causing death in the severe one short time.In the associated gas (main component is natural gas) of oilfield, often contain certain density hydrogen sulfide gas, well station staff is caused to very big security threat.
The technology of the associated gas of existing processing oilfield and existing shortcoming are as follows:
1) part well station, because associated gas yields poorly, does not have value, directly associated gas high altitude discharge, thereby arrives the object of diluting sulfureted hydrogen gas concentration.The shortcoming of the method is: waste natural gas energy resource, contaminated environment.
2) for most wells station, oil well associated gas centralized recovery, for the burning of oil field well station heating furnace, not only can make full use of the energy, can also avoid directly discharge and the environmental pollution that causes.But from scene, if associated gas hydrogen sulfide content concentration is higher, directly at the burning of well station heating furnace, the SO of generation
2gas is equally harmful to well site (station) staff, and environment is caused to new pollution.
Utility model content
Main purpose of the present utility model is the technological deficiency in order to overcome above-mentioned existing processing oilfield associated gas, provide a kind of device of removing hydrogen sulfide in oil well associated gas, for solving current oil well associated gas poisonous and harmful, waste energy and the problem of contaminated environment.
In order effectively to remove oil well pernicious gas hydrogen sulfide, the utility model provides a kind of device of removing hydrogen sulfide in oil well associated gas, this device comprises: for the closed box of accommodating working solution, for oil well associated gas is introduced to the admission line that reacts to remove hydrogen sulfide in closed box with working solution, and for removing associated gas after hydrogen sulfide and draw the pipeline of giving vent to anger of closed box; Wherein:
In casing, be the space of accommodating working solution, admission line interface, escape pipe line interface are set on casing, and casing top arrange dosing mouth, lower box arranges leakage fluid dram;
Described admission line stretches in casing by the admission line interface on casing and to extend to bottom half horizontally disposed, on the horizontally disposed admission line of bottom half, is provided with venthole;
The inlet end of the described pipeline of giving vent to anger stretches in casing by the escape pipe line interface on casing, and is positioned at operating fluid level top.
According to specific embodiments of the present utility model, in removal oil well associated gas of the present utility model, the device of hydrogen sulfide comprises two described closed boxes that are arranged in parallel.In the utility model, the concrete shape of closed box is not done to special requirement, simply there is the cuboid of certain length.
According to specific embodiments of the present utility model, in removal oil well associated gas of the present utility model, in the device of hydrogen sulfide, described admission line interface, escape pipe line interface lay respectively at the two ends of casing length direction.Be appreciated that described length direction refers to horizontal direction on ordinary meaning but not vertical direction.
According to specific embodiments of the present utility model, in removal oil well associated gas of the present utility model, in the device of hydrogen sulfide, described dosing mouth is positioned at casing central upper portion position.
According to specific embodiments of the present utility model, in removal oil well associated gas of the present utility model, in the device of hydrogen sulfide, described venthole is equidistant on the horizontally disposed admission line of bottom half evenly to be arranged.
According to specific embodiments of the present utility model, in removal oil well associated gas of the present utility model, in the device of hydrogen sulfide, described working solution is sodium hydroxide solution, potassium hydroxide solution or cesium hydroxide solution.
Device of the present utility model, is mainly mounted in oil well associated gas and leads in the pipeline flow process of heating furnace when application, add working solution as sodium hydroxide solution, potassium hydroxide solution, cesium hydroxide solution etc. by dosing mouth.Because hydrogen sulfide and working solution can react, as occurred to react as follows with sodium hydroxide solution:
H
2S+2NaOH＝Na
2S+2H
2O
So when oil well associated gas enters in casing, hydrogen sulfide content reacts with alkali metal soln, just can arrive the object of removing hydrogen sulfide.After heating furnace burning, both can't smell pungent SO
2smell, does not need by high altitude discharge yet, wastes energy, and contaminated environment.
The beneficial effects of the utility model are:
Structural design advantages of simple of the present utility model, can conveniently remove toxic gas hydrogen sulfide in oil well associated gas effectively, protects well station staff, can also solve the problem of natural gas waste and contaminated environment.Further, the casing of two sealings by parallel connection, is used alternatingly when can changing medicament and processing hydrogen sulfide gas, practical.
