摘要
Abstract
A technical investigation ,including process and system design ,equipments and facili‐ties ,and operations etc .,was carried out in a refinery to find the reasons of SO 2 emission in the tail gas beyond the standard .The results showed that the direct reason was oil and light hydrocarbon car‐rying with rich amine solution .Further ,investigation and analysis indicated that a series of reasons resulted in the oil and light hydrocarbon carrying with rich amine solution .The reasons included small size of gas‐liquid separator ,lower temperature of lean amine solution ,higher temperature of recycle hydrocarbon gas in up‐stream units ,faulting design of oil skimming in amine flash drum of up‐stream units ,and insufficient design flow rate of the torch gas from rich amine flash drum .To solve the a‐bove problems ,some corresponding solutions were put forward including the design of system and process flow design ,process indexes ,operation ,and equipment modification .关键词
