Abstract: With the comprehensive optimization of domestic refining and chemical resources, the plant scale is showing a trend of large-scale and integrated development. The utilization value and potential economic benefits of refinery dry gas are becoming increasingly significant, and the effective utilization of dry gas resources has gradually become a research hotspot. This article introduces the sources and properties of refinery dry gas, summarizes the main methods for recovering refinery dry gas, including cryogenic separation, adsorption separation, oil absorption, membrane separation, and cascade coupling recovery processes, and compares the advantages and disadvantages of different technical routes. In practical operations, companies should conduct sufficient technical evaluation and economic analysis of different schemes based on the characteristics of the equipment to determine the optimal process route, achieve maximum benefits, and improve the competitiveness of the enterprise in the market.
