Previously, a significant amount of pressure energy was wasted during the depressurization and distribution process of high-pressure natural gas long-distance transmission lines. OHZEC participated in the core engineering design of this project from start to finish, completing the entire process—including scheme review, construction drawing design , on-site construction coordination, and commissioning— within just one year , while also optimizing the technical solutions to reduce costs and increase efficiency. Ultimately, through multi-party collaboration, the unit was successfully connected to the grid, achieving automatic distribution and facility backup operation without affecting the safe operation of existing stations , thus realizing a unity of technological breakthrough and value creation.

The project is designed to generate 3.5 million kilowatt-hours of electricity annually, saving approximately 430 tons of coal and reducing carbon emissions by 3,480 tons per year, demonstrating significant environmental benefits. OHZEC, as the design firm, achieved a breakthrough in this field, providing a domestically developed benchmark solution for the efficient recovery and utilization of natural gas pressure energy. In the future, the company will continue to innovate , build a new ecosystem for green and low-carbon development , and continue to deepen its expertise in the new energy field, achieving even greater success.
