Ten years of rapid development in chemical processing equipment; praise for China’s prosperity and strength. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* On June 6, 2023, Tieshanpo Gas Field, China’s first self-developed ultra-high sulfur content gas field, whose 8 core pieces of equipment were manufactured by Lansi Heavy Equipment, reached full production capacity. The corrosion-resistant alloy composite material equipment developed by Lanshi Heavy Equipment has played a role in helping China make new breakthroughs in the technology for developing ultra-high sulfur content gas fields. The Tieshanpo gas field is located in Dazhou, Sichuan Province. With a maximum hydrogen sulfide content of 16.59%, it belongs to the category of ultra-high sulfur content gas reservoirs, and it is currently the gas field in China with the highest hydrogen sulfide content that is in operation. Due to the complex geological origins of high-sulfur gas reservoirs and the intricate patterns of fluid phase changes, coupled with the highly corrosive and toxic nature of high-sulfur natural gas, the development of such acidic gas reservoirs presents significant technical challenges and stringent safety requirements. Throughout history, the safe, clean, and efficient development of ultra-high-sulfur gas fields has remained a global challenge. Among them, the material selection for the surface gathering and transportation systems in ultra-high sulfur content gas fields, as well as overall corrosion control, represent critical challenges. The equipment for the surface engineering project aimed at developing the Feixianguan Formation gas reservoir, developed and manufactured by LANSHI Heavy Equipment, includes 8 core units such as TEG absorbers, metering separators, inlet separators, filtration separators, gravity separators for feed gas, and coalescers for feed gas. During the development of this equipment, Lanshi Heavy Equipment actively responded to customer needs. Drawing on its experience in manufacturing nickel-based alloy equipment such as N08810 and N08120, it determined the optimal solution for product fabrication. For the first time, it utilized the NS1402+Q345R (R-HIC) corrosion-resistant alloy bimetallic composite material, thereby creating new products, technologies, and manufacturing processes for overall corrosion control, and achieving their practical application in engineering projects. During the manufacturing process, Chongzhuang Refining & Chemical Company worked in close collaboration with relevant departments, kept a close eye on key milestones, formulated reverse schedules, strengthened responsibilities for safe production, refined various measures and implemented strict controls. By improving work methods and optimizing process plans, the company ensured high-quality delivery of products, thereby providing the necessary equipment support for the smooth operation of the project.
