The oil refining unit in petrochemical industry is for the purpose of processing crude oil, producing different varieties of gasoline, diesel, kerosene and other fuel oils, lubricating oils and chemical raw materials.
The basic requirements of the oil refining plant for the valve: meet the process requirements, ensure the service life of the valve, easy to operate and maintain, compact structure, safe and explosion-proof.
1. Requirements for sealing
Stem seal: The packing used in the valve must meet the requirements of the process medium and adapt to the temperature and pressure of the medium. Valve stuffing boxes often leak during operation of many units, so many refineries replace all packing before commissioning.
2. Requirements for materials
Valve materials used in oil refining plants mainly include carbon steel, alloy steel and stainless steel. For the development of the refining process, the changes in the properties of crude oil, the deep processing of crude oil, and the increase in temperature and pressure of operating conditions, there are new requirements for valve materials, such as corrosion-resistant materials SS316 and polymeric linings.
3. Safety requirements
The oil refining industry is prone to flammable and explosive accidents during transportation, so the safety requirements for valves are strict, and explosion-proof and combustion-proof must be performed. For example, explosion-proof electric ball valves and explosion-proof electric butterfly valves can be well used in this medium.
4. Specification requirements
The oil refining industry plays an important role in the national economy, and the economic benefits of oil refineries are closely related to their scale. Therefore, the large-scale refinery is a future development trend. The advantages are to save investment, reduce land occupation, reduce costs, and reduce energy consumption, so the trend of automated valves is getting more and more attention.
