Puyang Yongjin Chemical Improves the Safety of Plant Operations Author/Source: Puyang Yongjin Chemical Co., Ltd. Date: 2022-04-01 Clicks: 6 On March 29, Puyang Yongjin held a meeting in the second conference room to discuss the investigation report on the boiler water wall tube rupture accident that occurred on January 26 at Hebi Coal Chemical. Leaders from various departments of Puyang Yongjin as well as engineering and technical staff attended the meeting, which was chaired by Cao Honggang, the head of the Production Technology Department. At the meeting, a study was first conducted on the accident case titled “Accident involving boiler flameout caused by rupture of the boiler water wall in the Power Plant”. In this incident, ruptures of the boiler water walls occurred in both Boiler B and Boiler A of the Power Plant, leading to boiler flameouts. The root cause was a leak in the heat exchanger of the gasification unit, which allowed acidic water to enter the demineralized water system; this resulted in a low pH level in the boiler water. Due to untimely emergency responses by relevant personnel, the boilers operated for an extended period under conditions of low feedwater pH, causing corrosion of their water walls. Eventually, this led to sequential ruptures of the water walls in Boilers B and A. Currently, the plant is in the preparation phase for commissioning, and each branch factory is focusing on several key areas: first, strict management of process and equipment changes, with enhanced and thorough risk analysis for such changes. Second, strictly implement the control of the three types of abnormalities, streamline the processes for handling abnormal data, and enhance employees’ sensitivity to key process parameters as well as their awareness of safety risks associated with their roles. Third, strengthen emergency management work. Improve emergency response plans based on actual conditions, develop drill plans, organize drills, and promptly address any issues identified during the drills. Fourth, strengthen safety education and training. Strengthen various safety training programs for employees, enhance their safety awareness and professional skills, and improve their ability to handle emergencies ； Carry out safety production awareness campaigns in a thorough manner, draw profound lessons from accidents, apply those lessons to similar situations, and strengthen the sense of responsibility among all employees to prioritize safety.
