Abstract: Provided is a method for treating an oil gas, which can realize high-efficiency separation for and recovery of gasoline components, C2, C3, and C4 components. The method first conducts separation of light hydrocarbon components from gasoline components, and then performs subsequent treatment on a stream rich in the light hydrocarbon components, during which it is no longer necessary to use gasoline to circularly absorb liquefied gas components, which significantly reduces the amount of gasoline to be circulated and reduces energy consumption throughout the separation process. Besides, in this method, impurities, such as H2S and mercaptans, in the stream rich in the light hydrocarbon components are removed first before the separation for the components. This ensures that impurities will not be carried to a downstream light hydrocarbon recovery section, thus avoiding corrosion issues caused by hydrogen sulfide in the light hydrocarbon recovery section.

Abstract: The present invention relates to the field of petrochemical information processing. Provided are a petrochemical equipment corrosion treatment method, apparatus, and system. The petrochemical equipment corrosion treatment method comprises: adopting a corrosion environment parameter analysis method, first acquiring a query request, and determining a corrosion type of petrochemical equipment according to a corrosion environment parameter of the petrochemical equipment in the query request (S101); further retrieving a corrosion record corresponding to the corrosion type (S102); and sending the corrosion record to a specified terminal (S103). Thus, related personnel can receive and read a corrosion record by means of a specified terminal, such that the related personnel can obtain corresponding references during corrosion treatment on petrochemical equipment.
