Sour gas transport issues
Thread Content
Dear sea friends, let’s discuss the long-distance transportation of low-temperature methanol-washed acid gas. What are the special requirements for transporting ingredients such as sour gas, hydrogen sulfide, 28% carbon dioxide, and 65% carbon dioxide over long distances? (about 4KM)
The pressure is too low. Is it wrong? Without pressure, there is no motivation. If you want to transport it over a long distance, you need to use a compressor to compress it.
2# baozhu200499 The pressure is very low and a compressor is needed. Are there any special requirements for materials? Can carbon steel be used?
When transporting acid gas over long distances, safety factors must be taken into consideration
Carbon steel is not suitable. Under pressure conditions, acid gas will cause serious corrosion to the compressor.
Generally speaking, there should be no requirements. There is basically no moisture in the outlet gas, and there is basically no corrosion to the pipeline. However, if the torch pipelines are connected together, if other gases in the torch flow back, it may have an impact. Therefore, it is generally necessary to conduct pipeline drainage and prevent other moisture-containing gases from flowing back.
It is best to make sulfuric acid by wet method nearby. The transportation distance is too long. The main reason is hydrogen sulfide leakage. No one dares to take responsibility for safety.

If the pipeline is long, your pressure is indeed low, which can be solved by using a pressurizing device. As for the material of the pipeline, I think carbon steel is fine. The requirement is to strictly control the water content and temperature at the inlet. It is best to add a check valve at the outlet to prevent the acid gas from flowing back into the equipment. It is also necessary to ensure that the outlet pressure is higher than the pressure of the pipe network. Do not add diversion exhaust in the pipeline to prevent harm to people.
