Pipeline installation for the hydrogen-ammonia unit supporting the nylon chemical industry project at Henan Shenma Hydrogen Chemistry Co., Ltd. was completed. Author/Source: Huahua Net Coal Chemicals. Date: May 14, 2023. Clicks: 17. At 10:30 a.m. on May 10, a ceremony was held at the site to the west of the gasification unit for the hydrogen-ammonia project as part of the nylon chemical industry project at Henan Shenma Hydrogen Chemistry Co., Ltd. The project owner from Shenma, the supervisor, Huisheng Engineering, and the construction team were all present to witness the completion of pipeline installation at the gasification unit and the successful completion of the flaw detection tests, thus fulfilling a key milestone outlined in the commitment given by Huisheng Engineering on February 26. At the node completion ceremony, Mr. Pan, Deputy General Manager of the owner’s company Hydrogen Chemistry, highly praised Huisheng Engineering for its efforts and achievements in construction organization, safety management, and quality control. It is also hoped that Huisheng Engineering will, as in the past, meet the milestones for mechanical completion ahead of schedule during the subsequent pipeline pressure testing, cleaning, and airtightness testing processes, while ensuring safety and quality. The total welding length for the gasification unit of the Shenma project, including any modifications, is 130,000 inches; 127,000 inches have been completed so far, representing a completion rate of 97.7%. Except for the changes and optimizations to the weld joints, all of the originally designed weld joints have been completed. The non-destructive testing for all completed welds has been completed simultaneously. While the installation work is being carried out, pipeline pressure testing and purging are also taking place simultaneously. There are a total of 172 pipeline pressure testing kits for the gasification unit, 89 of which have been completed, giving a completion rate of 51.7%. The pipelines for utility media such as process water, demineralized water, and instrument air have been purged successfully and put into use. The hydrogen and ammonia production project of Henan Shenma Hydrogen Chemistry Co., Ltd. is designed to have an annual production capacity of 400,000 tons of ammonia and 400 million cubic meters of hydrogen. The total investment for this project is 2.768 billion yuan. Advanced coal-water slurry gasification technology is used in place of fixed-bed gasification technology. Construction of the project began in mid-November 2021. It is a large-scale chemical project undertaken by Pingdingshan City and the group in order to develop \"China’s Nylon City\", to strengthen the upstream part of the nylon industry chain, and to address the shortages of raw materials such as hydrogen and liquid ammonia.
