Abstract
The utility model relates to chemical equipment and in particular relates to equipment for making sodium hydrosulfide from acidic gas in a refinery plant. According to the technical scheme, the equipment comprises an acidic gas inlet, a gas outlet, a liquid phase inlet, a liquid phase outlet, a cooling medium outlet, a transmissible pressure gauge opening, sight glass openings, a transmissible thermometer opening, transmissible liquidometer openings and a tank body, wherein the acidic gas inlet, the gas outlet and the transmissible pressure gauge opening are formed in the top of the tank body; the transmissible liquidometer openings are formed in one side of the tank body, and the liquid phase inlet, the sight glass openings and the transmissible thermometer opening are formed in the other side of the tank body; the liquid phase outlet and the cooling medium outlet are formed in the bottom of the tank body. The equipment disclosed by the utility model has the beneficial effects that due to the arrangement, acidic gas from the acidic gas inlet can be uniformly distributed in a liquid phase of the equipment and is in reversible contact with alkaline liquid from the liquid phase inlet, so that high-efficiency recycling of the acidic gas can be realized; the investment cost of the equipment is low; the operation is simple; the product cost is low; secondary pollution is avoided.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, and particularly a kind of sour gas system is got NaHS equipment.
Background technology
Along with the increase of China's sour crude processing capacity in recent years, in refinery exhaust, the output of sour gas is also increasing.The main component of sour gas is hydrogen sulfide, and hydrogen sulfide can not only cause corrosive pipeline, also can seriously cause environmental pollution, is detrimental to health.Along with the enhancing of people's environmental consciousness, and guarantee making full use of of resource, hydrogen sulfide must be recycled.
The recoverying and utilizing method of sour gas is mainly to produce sulphur, NaHS, sulfuric acid, ammonium sulfite at present.For medium and small refinery, sour gas total amount is little, build sulphur, sulfuric acid, ammonium sulfite plant investment large, and key equipment still relies on foreign technology, therefore what be applicable to medium-sized and small enterprises is to build NaHS device, wherein key equipment is NaHS producing equipment, and can its performance is directly connected to sour gas high efficiente callback and production cost thereof.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of sour gas system to get NaHS equipment.
Its technical scheme is: comprise sour gas import, gas vent, liquid phase import, liquid-phase outlet, cooling medium outlet, teletransmission pressure gauge mouth, visor mouth, teletransmission thermometer mouth, far transmission level meter mouth, tank body, the top of tank body is provided with sour gas import, gas vent and teletransmission pressure gauge mouth, one side of tank body is provided with far transmission level meter mouth, the opposite side of tank body is provided with liquid phase import, visor mouth, teletransmission thermometer mouth, and the bottom of tank body is provided with liquid-phase outlet, cooling medium outlet.
The beneficial effects of the utility model are: by above setting, the sour gas coming from sour gas import can be uniformly distributed equipment liquid phase, and the alkali lye coming with liquid phase import realizes reverse contact, realize the high efficiente callback of sour gas.This equipment also can be connected a plurality of same equipment according to hydrogen sulfide content in sour gas and to discharging the requirement of sour gas in tail gas, can realize sour gas and contact with the full regression of alkali lye, produces 48% high-quality NaHS product.Final tail gas of discharging is back to oil refinery dry gas pipe network; Equipment investment expense is low, simple to operate, and product cost is low, non-secondary pollution.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is three structural representations that equipment is in series;
In upper figure: sour gas import 1, gas vent 2, liquid phase import 3, liquid-phase outlet 4, cooling medium outlet 5, teletransmission pressure gauge mouth 6, visor mouth 7, teletransmission thermometer mouth 8, far transmission level meter mouth 9, gas blowout 10, tank body 10.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises sour gas import 1, gas vent 2, liquid phase import 3, liquid-phase outlet 4, cooling medium outlet 5, teletransmission pressure gauge mouth 6, visor mouth 7, teletransmission thermometer mouth 8, far transmission level meter mouth 9, tank body 10, the top of tank body 10 is provided with sour gas import 1, gas vent 2 and teletransmission pressure gauge mouth 6, one side of tank body 10 is provided with far transmission level meter mouth 9, the opposite side of tank body 10 is provided with liquid phase import 3, visor mouth 7, teletransmission thermometer mouth 8, and the bottom of tank body 1 is provided with liquid-phase outlet 4, cooling medium outlet 5.
This equipment also can be according to hydrogen sulfide content in sour gas and to discharging the requirement of sour gas in tail gas, a plurality of same equipment is connected and (seen Fig. 2, three situations that equipment is in series), alkali lye enters from the liquid phase import 3 of III equipment, sour gas enters from the sour gas import 1 of I equipment, tail gas is discharged from III equipment gas vent 2, and product NaHS is from liquid-phase outlet 4 extraction of I equipment.Sour gas and sufficient reverse contact the in alkali lye equipment inside and outside can be realized like this, high-quality product can be produced.
