The process for the solid waste treatment via coal-to-hydrogen production in Shandong has been fully operational, producing qualified hydrogen. Author/Source: Jinhua Furnace; Date: 2020-06-19; Clicks: 7. The coal-to-hydrogen project at Qinghe Chemical in Shandong was successfully put into trial production on June 15. The entire process chain of the facility is operational, the equipment is functioning well, and the qualified hydrogen has been integrated into the hydrogen pipeline network. Coal-to-hydrogen plants utilize a new type of coal gasification technology, which, compared to traditional coal-to-hydrogen processes, offers better process stability, greater adaptability to different types of coal, higher system operational efficiency, and lower hydrogen production costs. The successful commissioning of this device has provided an additional high-quality hydrogen source, which is of great significance for further enhancing the company’s overall competitiveness. The facility received approval for trial production on June 4, and the startup procedure for trial production began on June 9. On June 14, the quality of the hydrogen met the required standards; after a day of optimization adjustments, all parameters stabilized and the facility reached normal operating conditions, marking the successful commencement of its trial production. At 13:28 on June 10, the gasifier of the coal-to-hydrogen project in Qinghe, Shandong, was successfully fed for the first time. The technicians from Qinghe Chemical Company and Qingchuang Jinhua Company resolved the issues that existed prior to the trial run at the project site, as well as those that arose during the trial run, ensuring that the gasification furnace was successfully fed material on the first attempt. The coal-to-hydrogen project of Shandong Qinghe Chemical Technology Co., Ltd. (formerly known as Shandong Jincheng Chemical Co., Ltd.) utilizes the water-cooled wall waste-heat gasifier technology of slurry coal gasification (Jinhua Furnace 3.0). The gasification pressure is 6.5 MPaG, with each gasifier producing 60,000 Nm3/h of usable gas (CO + H2). The gasification unit consists of two gasifiers, one in operation and one as a backup. The coal-to-hydrogen project of Shandong Qinghe Chemical Technology Co., Ltd. involves feeding solid waste from the Qinghe plant, as well as from companies such as Shandong Jincheng Heavy Oil Chemical and Jincheng Petrochemical Group, into gasifiers for use as raw material in hydrogen production. 21,945.7 tons of hazardous waste and 1,089 tons of general solid waste are recycled annually. The types of waste are as follows: 1. Sludge and scum from Shandong Jincheng Heavy Oil Chemical Co., Ltd. (with a moisture content of 80%), 1,875 tons per year; these are classified as hazardous waste (HW08). 2 Shandong Jincheng Heavy Oil Chemical Co., Ltd.: biochemical sludge, 1,089 tons per year. 3 Shandong Jincheng Petrochemical Group Co., Ltd.: aged sulfolane solvent, 75 tons per year, classified as hazardous waste (HW06). 4. Shandong Qinghe Chemical and Shandong Jincheng Heavy Oil Chemical waste ion exchange resins, 97.7 tons per year, classified as hazardous waste (HW13). 5 Shandong Qinghe Chemical Technology Co., Ltd. – floating oil, 19,710 tons per year; classified as hazardous waste (HW08).
