The first 100% petroleum coke-based hydrogen production complex in China, utilizing GE gasification technology, began producing qualified hydrogen. Author/Source: Gasification World Date: November 16, 2022 Clicks: 19 On November 16, the petroleum coke hydrogen production complex at Guangdong Petrochemical, which was designed and constructed by Huanqiu Company, successfully produced qualified hydrogen. It marks the complete success in the commissioning of the country’s first 100% petroleum coke-based hydrogen production complex. The petroleum coke hydrogenation unit at Guangdong Petrochemical is the largest in terms of floor area, the most numerous in terms of structures, the greatest in terms of concrete pouring volume, and the highest in terms of the number of equipment units within the entire Guangdong Petrochemical refining and chemical integration project. It is also China National Petroleum Corporation’s first petroleum coke hydrogenation unit. The plant utilizes GE’s 6.5 MPa rapid cooling gasification technology; it uses petroleum coke, a by-product of oil refining units, as raw material. Through conversion and purification processes, it supplies hydrogen and fuel gas to the entire plant. The annual production of hydrogen amounts to 1.6 billion standard cubic meters, while the annual production of fuel gas is 3.1 billion standard cubic meters. The plant consumes 231.09 tons of petroleum coke per hour. On June 2, 2022, the petroleum coke hydrogenation complex was successfully handed over. On July 9, 2022, all commissioning work for the coal coke storage and transportation system in the gasification unit of the petroleum coke hydrogen production complex was completed ； On August 1, the chemical cleaning of the high-pressure oxygen and nitrogen pipelines was approved ； On August 15, all tasks related to the no-load testing of the 4 reciprocating compressors were completed ； On September 11, the circular stockyard successfully received the first batch of raw coal ； On September 28, the coal grinder in the slurry preparation unit was tested with feed input, and it operated normally, meeting the conditions for formal slurry production. On October 8, the commissioning of all 8 compressors was completed, meeting the requirements for starting up the plant ； On October 21st and 30th, methanol material and propylene were successfully fed in sequentially ； On November 16, the facility began producing hydrogen that met the required standards, becoming the first 100% petroleum coke-based hydrogen production complex in the country to operate successfully! Guangdong Petrochemical uses GE gasification for hydrogen production, domestic wide-temperature sulfur-resistant shift technology, domestic low-temperature methanol washing, and PSA for hydrogen production; these processes supply the plant with 1.6 billion standard cubic meters of hydrogen and 3.1 billion standard cubic meters of fuel gas per year. Project Overview: The petroleum coke hydrogenation complex of Guangdong Petrochemical was put into operation on December 16, 2019. Covering an area of 220,000 square meters, the project involves the installation of 1,238 sets of equipment, the welding of 1.2 million inches of process pipelines, the pouring of 260,000 cubic meters of concrete, and the installation of 17,000 tons of steel structures. It is the largest single unit among all the facilities in Guangdong Petrochemical’s integrated refining and chemical processing complex, with the most buildings, the largest amount of concrete poured, and the highest number of equipment units installed. It is also China National Petroleum Corporation’s first petroleum coke hydrogenation facility. The entire facility comprises 6 gasification units that utilize GE’s 6.5 MPa rapid cooling gasification technology. Using petroleum coke, which is a by-product of oil refining processes, as raw material, these units carry out conversion and purification processes to supply hydrogen and fuel gas to the whole plant. The annual production of hydrogen amounts to 1.6 billion standard cubic meters, while the annual production of fuel gas reaches 3.1 billion standard cubic meters; the plant consumes 231.09 tons of petroleum coke per hour.
