[Chemical Knowledge]：Matters needing attention of hydrogen sulfide in crude oil dehydration

Read： 488 Time：14months ago Source：Transform the World with Simplicity

In the petroleum processing industry, crude oil dehydration is a very important link, which can effectively improve the quality of crude oil and reduce the corrosion and blockage problems in the subsequent processing. However, in the process of crude oil dehydration, we need to pay special attention to the presence of hydrogen sulfide.
Hydrogen sulfide is a colorless, irritating gas, highly toxic, highly flammable, and corrosive to metal equipment. Therefore, in the process of crude oil dehydration, if not paid attention to and handled, it may cause serious safety hazards to operators and equipment.

For crude oil containing hydrogen sulfide, it is necessary to carry out sufficient gas phase treatment before dehydration to minimize the content of hydrogen sulfide. At the same time, during the dehydration process, it is necessary to ensure that the sealing performance of the equipment is good, and the dehydration equipment is regularly inspected and maintained to avoid hydrogen sulfide leakage or corrosion of the equipment.

operators in the dehydration operation, the need to strictly abide by the relevant safety procedures, wear the corresponding protective equipment, to ensure personal safety. At the dehydration site, a gas detector should be set up to monitor the hydrogen sulfide content in the air in time, and regularly conduct safety inspections and hidden dangers on the equipment and the site to ensure the safety of the dehydration process.
In addition, it is necessary to carry out special treatment for the dehydrated wastewater to reduce the pollution to the environment, and to set up the corresponding accident emergency plan, so that the hydrogen sulfide leakage accident can be quickly and effectively dealt.
In general, it is important to pay attention to the presence of hydrogen sulfide in the crude oil dehydration process. Only by making relevant safety protection measures and strictly abiding by the operating procedures and safe operating procedures can we ensure the safety of the dehydration process, protect the operators and equipment, and at the same time, it is also a performance of being responsible for the environment.
