The news comes from online sharing? From June 17th to 28th, the HAZOP (Hazard and Operability Analysis) review meeting for the ethylene glycol production unit of Yulin Chemical Company’s 1.8 million tons per year ethylene glycol production facility was successfully held at Donghua Engineering Technology Co., Ltd. Relevant leaders and technical personnel from Shaanxi Coal Group Yulin Chemical Co., Ltd., Donghua Engineering Technology Co., Ltd., and Kako Chemical Technology Co., Ltd. attended the meeting. To ensure the reliability and accuracy of the HAZOP review for the ethylene glycol plant, the three parties jointly established a HAZOP review team composed of professional engineers from areas such as production management, process engineering, safety, equipment, electrical systems, and instrumentation, along with the HAZOP lead.
During the meeting, the HAZOP review team carried out system and node segmentation of the ethylene glycol plant based on the PFDs, P&ID drawings, and related technical documents of the ethylene glycol process package. They defined deviations and trigger words, and by utilizing the Shaanxi Coal Group Yulin Chemical Safety Risk Matrix, analyzed the causes of parameter deviations within each node, the possible consequences, as well as the likelihood, severity, and risk level of such risks. Using LOPA analysis and verification, and based on the existing safety measures in the design as well as the recommended protective measures, the likelihood, severity, and risk level of the mitigated risks are rated again. The HAZOP review team also conducted a SIL (Safety Instrumented Function) level assessment for the ethylene glycol plant. The HAZOP review team followed the established HAZOP review process to analyze and assess whether the current safety measures meet the requirements regarding the maximum acceptable level of risk as defined in the company’s safety risk matrix; finally, it provided suggestions for improvement based on the actual production operations.
Giving attention to HAZOP reviews during the design phase greatly facilitates subsequent work.
“Safety first, prevention foremost, comprehensive management.” For enterprises, conducting safety assessments of production facilities that are under design, construction, or in operation using scientific and rigorous methods in accordance with international standards has become a top priority for ensuring safe production.
It seems that designers also need to understand safety
Well said. In design, consideration should be given to the safety and feasibility of construction, as well as the feasibility of operation
Designers must participate in the preliminary HAZOP analysis for the project
