A sulfur separation and removal device for high-sulfur gas fields

Abstract

A sulfur separation and desulfurization device for a high-sulfur gas field mainly includes a liquid-solid separation tank, a sulfur screw conveyor, a sulfur tank truck, and a data acquisition and control module. After the sulfur and water mixture enters the sulfur accumulating chamber, it relies on the density difference of water and sulfur to separate by natural sedimentation, and the sulfur barrier is used to prevent the deposited sulfur particles from entering the water phase. The data acquisition control module monitors the height of deposited sulfur at all times. When the thickness of deposited sulfur reaches a critical value, the motor of the screw sulfur conveyor drives the spiral blade to rotate. The pipe goes into the sulfur tank car. Compared with the existing technology, the present invention does not need to shut down the separator during the desulfurization process, does not affect normal production, is airtight throughout, has high safety, uniform sulfur discharge speed, and the device has simple structure, low construction cost and maintenance cost low and has broad application prospects.

Description

Technical field: [0001] The invention relates to a sulfur separation and desulfurization device for a high-sulfur gas field, in particular to a device for separating deposited sulfur and produced water in a high-sulfur gas field, and discharging the separated sulfur out of a separator, which belongs to high-sulfur natural gas production area. Background technique: [0002] In sour gas fields with high sulfur content, elemental sulfur dissolves in sour natural gas in the form of polysulfides. When the gas well is exploited, the amount of dissolved elemental sulfur in the gas will also decrease due to the decrease in temperature and pressure, and the supersaturated sulfur It will be precipitated in the gathering and transportation system, and then deposited. Sulfur deposition is a huge hazard, mainly reflected in the following aspects: [0003] (1) The equipment and pipe network of the gathering and transportation station are complicated, and elemental sulfur is easily depos...

AI Technical Summary

Problems solved by technology

[0003] (1) The equipment and pipeline network of the gathering and transportation station are complex, and elemental sulfur is easily deposited on the throttle orifice, tee, etc., which seriously affects the safe operation of the equipment

[0004] (2) Blocking the downstream gathering and transportation pipeline, resulting in a decrease in the efficiency of the gathering and transportation pipeline

In the process of gathering and transportation, as the temperature and pressure drop, the solubility of natural gas to sulfur will decrease, and sulfur will be precipitated, which will deposit on the pipe wall, reduce the effective flow area of ​​the pipe, and increase the energy consumption of transportation. , the accumulation of sulfur crystals can block fluid passages and lead to well shut-in and shutdown

[0005] (3) Increase the risk of corrosion in the gathering and transportation system

This method affects normal production, the labor intensity of the staff is high, there is a risk of poisoning, and safety is difficult to guarantee
