[Haichuan Chemical Salary Updates] Zhenhai Refining & Chemical’s coal-coke hydrogen production unit was successfully handed over
Thread Content
On December 28, 2018, the coal-coke hydrogen production unit at Zhenhai Refining & Chemical completed its handover successfully. Currently, the hydraulic testing of the external pipeline network is in progress, and qualified products are expected to be available by January 28, 2019. The coal coke hydrogenation unit is the main facility in Zhenhai Refining & Chemical’s project portfolio for restructuring, upgrading, and improving the performance of its existing facilities. The project consists of process production units, utility systems, supporting auxiliary production facilities, storage and transportation systems, as well as peripheral facilities for the units. The normal hydrogen production capacity of the device is 120,000 standard cubic meters per hour. Since the commencement of the pile foundation work in June 2016, and going through several key phases such as pile foundation construction, civil engineering work, heavy equipment lifting, and equipment installation, the entire process took 2 years and 6 months. The project management department coordinated the efforts of various specialized project teams to overcome the challenges posed by tight deadlines and heavy workload during construction. The relevant operation departments and construction units adopted a working attitude of considering both parties as one team, working together to ensure the safe and high-quality completion of the project. Once put into operation, this project will further optimize the hydrogen balance at Zhenhai Refining & Chemical Co., significantly reduce the production costs of industrial hydrogen, enhance the company’s overall economic efficiency, and improve its resilience to risks.

This is an advanced technology worth promoting. Petroleum coke from refineries has always been a difficult-to-manage by-product; it accumulates in large quantities, and apart from being used in asphalt production, the only option left is to dispose of it through burning, which poses a serious threat to the environment. Coal coke hydrogen production involves crushing petroleum coke and mixing it with water-coal slurry, which is then fed into a gasifier to produce hydrogen, CO, and syngas; these substances serve as the main raw materials for oil refining hydrogenation processes as well as feed gases for downstream chemical plants, offering significant economic benefits.
At 10:17 on June 2, 2017, with the sound of a whistle, under the direction of the crane operators, the 1,250-ton main crane and the 280-ton auxiliary crane worked together: the main crane grasped the top part of the equipment while the auxiliary crane held onto its bottom, and thus Converter No. 1 was slowly raised to an upright position, aligned with its base, and settled in place vertically and steadily. The successful installation of the first unit in China’s first industrial application project based on proprietary slurry coal technology marks another milestone for China’s refining technologies, and it provides further assurance for the improvement of oil product quality at Sinopec Zhenhai Refining & Chemical Co., Ltd. The Zhenhai Refining & Chemical Co., Ltd. coal coke hydrogen production project boasts three advantages: technology, cost, and environmental protection. The coal-based hydrogen production project utilizes the SE water-coal slurry gasification technology. It was included in Sinopec’s “Ten Dragon” scientific and technological research projects in 2015, with joint efforts from Zhenhai Refining & Chemical Co., Ningbo Engineering Company, and East China University of Science and Technology; a total of 19 patents have been developed for this project. Currently, the patented technology of General Electric is widely used in China; the application of the SE coal-water slurry gasification technology will fill this technological gap and further enhance China’s reputation in the field of refining and chemical processing technologies. Second is the advantage in terms of efficiency: by utilizing low-cost raw materials such as petroleum coke from upstream facilities, high-purity hydrogen can be produced, thereby laying the foundation for a low-cost source of hydrogen in the overall process. Third is the environmental advantage: this project makes clean use of coal and petroleum coke, enables the green recycling of biochemical sludge from wastewater treatment plants, reduces the burden on environmental treatment efforts, and creates a circular economy industry chain. High-purity hydrogen is an important resource for improving the quality of oil products; therefore, the completion of the coal coke hydrogen production project is a prerequisite for upgrading the quality of oil products at Zhenhai Refining & Chemical Co., Ltd. The coal coke hydrogen production project consists of production units, utility systems, supporting auxiliary production facilities, storage and transportation systems, as well as peripheral facilities around the units. On August 16, 2016, the first pile was driven for the project, with commissioning scheduled for mid-2018. By then, 120,000 standard cubic meters per hour of hydrogen will be supplied to the Zhenhai Refining & Chemicals oil quality upgrading facility. The coal coke hydrogen production project at Zhenhai Refining & Chemical is the first major project in the restructuring project portfolio of the old area there to reach the hoisting phase. Zhang Yuming, General Manager of Zhenhai Refining & Chemical Co., He Jianbo, General Manager of Ningbo Engineering Company, along with representatives from the EPC and construction parties, attended the lifting ceremony.
It would also be a significant contribution if any research institution could develop methods for dealing with the alkali sludge generated during oil refinery operations.
This is also currently an issue with industrial waste salts
Happy New Year! I recommend Haichuan to your friends. More friends from Zhenhai Refining & Chemical are welcome to come and communicate
