High-Sulfur Crude Oil Processing Process H2S Leakage Grading Warning and Protective Measures

Abstract: As one of the major risks in high-sulfur crude oil processing, the H₂S exposure could be reduced by early warning of H₂S leaking. Based on the source and distribution of H₂S, the four-level warning mechanisms of H₂S leak is developed by using HSE risk identification system, which makes the H₂S concentration values as the grading index. The appropriate emergency measures are formed. To provide guidance for H₂S poisoning protection during high-sulfur crude oil processing, the safeguards to prevent H₂S poisoning are presented according to the cause of H₂S poisoning and "Human - Machine - Material - Regulation - Environment".
