Abstract
The oil and gas industry has a high level of risk, especially related to process accidents. Consequences arising from process accidents can include gas release, fire and explosion. Losses arising from process accidents can include fatalities, injuries, environmental damage, property or asset damage, company reputation and financial loss. The H2S removal unit is a unit that has a high potential for process accidents. Therefore, prevention and mitigation measures, such as implementing buffer zones, are needed to improve process safety in H2S removal units. This research uses a buffer zone identification method by first reviewing the risks of the H2S removal unit using HAZID, HAZOP and a risk matrix to identify the most likely and fatal process accident scenarios in the H2S removal unit. Analyze the consequences of gas release, fire and explosion by modeling with Shell FRED software. The results of the consequence analysis and modeling are translated into a buffer zone H2S removal unit design. Thus, it is hoped that the identification of this buffer zone can be a hazard mitigation for the H2S removal unit.
