[Ten years of major development in chemical equipment] From 812 to 2022, China’s first independently designed high-sulfur natural gas purification plant was put into operation in Sichuan
Thread Content
Looking at the great development of chemical equipment in the past ten years, I wish you all a happy new year and a safe and healthy family. The ocean is more exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. ------------------------------------------------------------------ In June 2022, the product gas of the ground engineering purification plant for the trial production of the reef shoal gas reservoir in the Jiange block of Guangyuan City, Sichuan was qualified for export, marking the first domestically designed high-sulfur natural gas purification plant that was successfully put into operation at one time. The project was successfully put into operation, setting a precedent for the first independent design of a high-sulfur natural gas purification plant in China. It is reported that the reef-shoal gas reservoir in the Jiange block is a gas reservoir with high sulfur content and high organic sulfur content. The ground project for trial mining of the reef-shoal gas reservoir in the Jiange block is currently * * It is a key project against the background of upgrading the quality index of commercial natural gas and further strictly controlling the SO2 emission concentration of tail gas. The project includes a new natural gas purification plant with a daily processing capacity of 1.4 million cubic meters, three new or renovated single well stations, and 56 kilometers of supporting gathering and transportation pipelines. The project adopts sulfur-containing gas dehydration and flash gas pressurized recovery processes.
The Southwest Branch of China Petroleum Engineering & Construction Co., Ltd. undertook the design of the entire project and the EPC work of the exhaust gas treatment device, evaporation and crystallization device, and integrated gathering and transportation skid. Faced with the risks brought by high H2S content and complex temperament conditions, as well as the continuous upgrading of commercial gas indicators and tail gas emission standards, the company organized industry experts and a capable design team to repeatedly demonstrate the applicability of the purification process. ； Use three-dimensional collaborative design to ensure accurate and efficient connection between majors. It is understood that this project adopts the construction concept of "skid-mounted station construction and modular factory construction". The exhaust gas treatment modules are built in an integrated skid factory and quickly assembled on site, which saves the construction period, reduces environmental impact, and ensures that the project construction is fast, safe, and reliable. After the completion of this project, it will help our country deepen our understanding of the characteristics of similar gas reservoirs, scientifically evaluate the productivity and stable production capabilities of gas wells, and accumulate experience in the development and production safety management of ultra-deep and high-sulfur gas reservoirs. At the same time, it will effectively ensure the supply of natural gas and green and low-carbon development in the old revolutionary areas in northern Sichuan. Up to now, the purification plant of this project has a stable daily processing capacity of 700,000 cubic meters, all parameters are normal, and the equipment is running smoothly.
