[Sea and Rivers: Insights from Other Places] Jinan Refining & Chemical’s low-temperature waste heat recovery heating project begins supplying heat to the grid
Thread Content
Recently, 5 heat pump units at the energy station of Jinan Refining & Chemical’s 4th circulating water plant were brought online one after another and successfully connected to Jinan’s heating network. This marks the official commissioning of Jinan Refining & Chemical’s low-temperature waste heat recovery heating project, which now provides heating for 1.5 million square meters of buildings in the eastern part of Jinan city. To alleviate the long-standing pressure on heat supply in the eastern area of Jinan and make full use of the waste heat from the circulating water at the Jinan Refining and Chemical Plant, the plant has partnered with Sinopec Lvyuan Geothermal Energy Development Co., Ltd. to carry out a project for recovering low-temperature waste heat from circulating water for heating purposes. This project utilizes heat pump technology to improve the quality of thermal energy, and constructs 2 heating power stations along with associated facilities. To ensure the successful commissioning of the project this winter, Jinan Refining & Chemical has carried out reconstructive renovations to the relevant circulating water facilities, built two new large-scale cooling towers, reorganized the layout of underground pipelines, and provided full support for GreenSource Company’s activities related to the construction of the energy station, the connection of pipelines, and hydraulic testing. It is estimated that once the project is fully operational, its total heating capacity will reach 200 megawatts, allowing for a reduction of 75,000 tons of standard coal to be consumed per heating season, thereby resulting in a significant reduction in carbon dioxide emissions.
