Abstract

Accidents in the chemical process industry can not only result in loss of life (fatality) and property but can also cause irreparable damage (assets and the environment) to the external environment. For companies whose industrial activities are processing, storing, distributing, transporting and using hazardous chemicals to carry out a Risk Analysis of the potential hazards of chemicals, and the stages of Hazard Identification against Chemicals are steps to prevent industrial accidents and also as a form of prevention. against work accidents and occupational diseases. The purpose of this study is to analyze the risk of chemical hazards in the Methanol transfer process in each operating process based on the P&ID Diagram document and to determine the potential hazards of chemicals in the process so that hazard control can be applied. This study focuses on the methanol transfer process in biodiesel companies using the Hazard and Operability Study (HAZOP) method. The results of the analysis after it was done that the value of before reduction after the application of safeguards on each item of the Methanol and Sodium Methylate Daily Tank process, the results of the after reduction risk assessment on the risk value changed from a Risk score of 20 to a Risk Score of 16. Based on the results of the Risk Analysis it can be seen that the risk analysis using the hazop method after safeguarding is obtained with an average risk level of moderate risk of 40%, low of 32% and high of 28%.
