Introduction

Natural gas streams may contain H2S and organic volatiles (i.e., mercaptans) that have toxic health effects. Refrigerants (e.g., ammonia and propane are often used for lowering process temperature in LNG facilities) can also have both toxic and flammable effects when released to the environment. The American Industrial Hygiene Association (AIHA) has issued Emergency Response and Guidelines (ERPGs) for air contaminants such as H2S, NH3 and methyl‐mercaptans. An exposure of H2S at a concentration level of 100ppm up to an hour is considered as life threatening for human beings. Process Safety is the science, technology, and management system to prevent, and mitigate unwanted events such as exposure of H2S.

The application of process safety principles begins with the identification of hazards. A hazard can be a material, or an activity, or a procedure that can cause harm to human, or environment, or incur economical loss. ...
