The chemical industry has seen significant development over the past decade; let’s praise the prosperity and strength of modern China. By sharing our insights, we can encourage more people to participate and make the discussions more lively. HaiChuan becomes even better with your involvement – we welcome everyone to join in the forum discussions. As July progresses and the weather gets hotter, be careful to prevent fires. ---------------------------------------------- Gasified syngas is characterized by high temperature, high pressure, flammability, explosiveness, and toxicity. If valves fail to seal properly and large amounts of high-pressure syngas leak out, it can lead to serious consequences such as fires, explosions, and poisoning. It can also affect the operations of the entire coal chemical industry as well as the surrounding environment. Additionally, such leaks result in significant economic losses. Therefore, it is crucial to ensure that the valves in these areas are safe and reliable. On May 29, 2022, the 2.2 million tons per year methanol synthesis unit of Ningxia Baofeng Energy Group’s 600,000 tons per year coal-to-olefins project successfully produced qualified methanol. Metal hard-sealed C-type wear-resistant ball valves, independently developed by Avafa Fluid Control Co., Ltd. and featuring independent intellectual property rights, were successfully applied in the pipelines for black water, gray water, quench water, and syngas in the gasification unit; some large-diameter C-type wear-resistant ball valves (600LB, 900LB, 24”; 600LB, 32”) were used in key sections of the system. Among them, the 600LB, 32\" large-diameter C-type wear-resistant ball valve was successfully applied to the main pipeline in the synthesis zone of the gasification unit in this project. The successful application of this C-type wear-resistant ball valve further confirms the advantage of using such valves as a replacement for conventional gate and butterfly valves in syngas main pipelines. It effectively addresses the problems associated with the use of gate and butterfly valves, such as difficulties in opening and closing, poor sealing, high leakage rates, and short service life. This innovation provides a convenient, fast, efficient, and reliable solution for operating syngas pipelines in coal gasification processes.
