Embodiment 1

[0036] This embodiment provides an acid gas sulfur recovery system in a natural gas purification plant, including a reaction unit, a sulfur granulation unit, and a tail gas incineration discharge unit, and the sulfur granulation unit and the tail gas incineration discharge unit are connected to the reaction unit;

[0037] Such as figure 1 As shown, the reaction unit includes an acid gas separator 1, an acid gas booster fan 2, an air blower 3, an acid gas heater 4, an adiabatic reactor 5, a sulfur condenser 6 and a sulfur separator 7, and the acid gas separation The acid gas booster fan 2 is connected to the back of the device 1, and the gas outlet of the acid gas booster fan 2 and the air blower 3 are merged to connect to the acid gas heater 4; the adiabatic reactor 5 is connected behind the acid gas heater 4, The sulfur condenser 6 is connected after the adiabatic reactor 5, and the sulfur separator 7 is connected after the sulfur condenser 6;

[0038] The sulfur granulatio...

Embodiment 2

[0050] This natural gas purification plant acid gas sulfur recovery system and method of the present invention is suitable for natural gas purification plant acid gas Content is lower than the situation of 5%, above-mentioned embodiment 1 can be in low concentration The described function is implemented in the case, but for the Content is lower than the situation of 1%, and embodiment 1 is more applicable, and sulfur recovery rate is higher, and tail gas emission also reaches discharge standard, but When the content is higher than 1%, although the structure in Application Example 1 is improved compared with the prior art, the effect is not very obvious. For this reason, further improvements are made in this embodiment.

[0051] This embodiment is on the basis of above-mentioned embodiment 1, as figure 2 As shown, the reaction unit is also provided with an isothermal reactor 15 and an intermediate gas heat exchanger 16 connected with the isothermal reactor 15. Between t...

Abstract

The invention belongs to the field of sulfur recovery and flue gas purification, and particularly relates to a natural gas purification plant acid gas sulfur recovery system and method. The system comprises a reactor, a sulfur condenser, a sulfur separator, a tail gas purification tank, a tail gas incinerator, a chimney, a liquid sulfur transfer pump, a sulfur granulator, a semiautomatic packaging machine and the like. By using the devices, H2S in the acid gas is converted into the elementary substance sulfur, the elementary substance sulfur is condensed into liquid sulfur, and the liquid sulfur is discharged to the liquid sulfur tank or liquid sulfur storage tank; after the tail gas is heated to 650 DEG C by the incinerator to convert H2S in the tail gas into SO2, the SO2 is discharged through the chimney; and the liquid sulfur is pumped to the granulator, subjected to granulation and packaging, and transported to the sulfur warehouse. By using the sulfur recovery method and system, the SO2 concentration in the discharged flue gas is lowered, high-purity sulfur can be obtained, and the natural gas purification plant low-concentration acid gas treated tail gas can be discharged after reaching the standard; the byproduct is high-purity sulfur which is easy for sales; and the system and method greatly lower the investment and operating cost of the devices.

Description

technical field [0001] The invention belongs to the fields of sulfur recovery and flue gas purification, and in particular relates to a system and method for recovering acid gas sulfur in a natural gas purification plant. Background technique [0002] The acid gas in the natural gas purification plant comes from the natural gas desulfurization device in the plant, and the desulfurization device adopts the alcohol amine desulfurization process. contain After the natural gas is desulfurized, it comes out of the top of the amine liquid regeneration tower, and the acid gas at about 100°C is cooled to 40-45°C by the acid gas air cooler, and then the acid gas after the acid condensed water is separated by the acid gas separator enters the Sulfur recovery unit. The main components of acid gas are with , and contains a small amount of free water and alcohol amine solution. [0003] for After the raw natural gas from the gas reservoir with low content passes through the des...
