The cause of the accident is still under investigation.
The reporter learned from the Management Committee of the Mengxi High-Tech Industrial Park in Etoke Banner, Ordos City, Inner Mongolia that at 8:30 a.m. on April 30, an explosion and fire broke out due to a gas pipeline leak at Huaye Coking Plant in the Mengxi Park of Etoke Banner, Ordos City, Inner Mongolia. As a result, one person died at the scene, two others died on their way to the hospital, and one person is currently under treatment in the hospital. Immediately after the accident, the Etoke Banner Party Committee and **activated the emergency rescue plan, making every effort to provide treatment for the injured, conduct investigations into the accident, and handle related follow-up matters. At present, the relevant officials from the Emergency Management Department of Inner Mongolia Autonomous Region are heading to the scene to handle the accident, and the cause of the accident is under further investigation. It is reported that Huaye Coal Coking Co., Ltd. in Ordos City, Inner Mongolia, has a registered capital of 22 million RMB; its main business areas include petroleum processing, coking, and nuclear fuel processing.

The chemical industry has been in a turbulent state since the pandemic
There were so many accidents in April; the goal for 2020 – to stay alive
Performing hot work at the pipeline leak? Or was it a pipeline leak caused by hot work? Incredible
Essentially, this company operates in the coking and metallurgy industry.
Huaye Coal Coking Co., Ltd. in Ordos City, Inner Mongolia, has a registered capital of 22 million RMB. Its main business areas are petroleum processing, coking, and nuclear fuel processing. What does nuclear fuel processing entail?
Is it the gas pipeline of an electrostatic tar catcher in the image?
Fire accident in electrostatic tar catcher caused by welding work Time: February 29, 2012, 14:46 Source: Internet Views: 290 Comments: 0 On April 16 of that year, a fire suddenly broke out at the top of Electrostatic Tar Collector No. 1 in the recycling workshop of Huaibei Coking Plant in Anhui Province; thanks to prompt action, a major fire disaster was averted. I. Accident Overview At 8:05 on April 16, gas leakage occurred at the flange of the thermocouple connection at the top of Electric Tar Collector No. 1 in the recycling workshop of the Coking Plant in Huaibei, Anhui, but it went unnoticed by anyone. Equipment maintenance was being carried out simultaneously in both the coking and chemical production workshops. When the welder connected the welding machine’s ground wire to the gas pipeline and started welding, current flowed through the gas pipeline to the thermocouple connection at the top of the electrostatic tar collector, causing mechanical vibration and sparks, which ignited the leaked gas and led to a fire. II. Accident Analysis The direct cause of this accident was the connection of the grounding wire to the gas pipeline during welding work. The indirect cause of the accident was a gas pipeline leak. Similar accidents have occurred at this plant, where welding was carried out with the grounding wire connected to the process pipelines, resulting in sudden pump shutdowns and motor damage. III. Lessons from Accidents and Preventive Measures Chemical plants are characterized by high-temperature and high-pressure operations, the presence of many flammable and explosive substances, and harsh operating conditions. Process pipelines and containers can be found everywhere. To save time, welders often connect the grounding wires of their welding machines to these pipelines and containers, which can easily lead to fires caused by the reactive materials involved. In severe cases, this can result in explosions, causing catastrophic accidents with loss of life and property damage. Therefore, some chemical manufacturing enterprises have explicitly stipulated that during welding operations, the grounding wire must not be connected arbitrarily to pipes, in order to prevent such accidents from occurring. To prevent such accidents from occurring again, the factory has taken proactive preventive measures. Safety training for welding workers has been strengthened, and strict operating procedures have been implemented; welders are prohibited from connecting the grounding wire of the welding machine to process pipelines and the equipment itself during welding operations.
