Let’s give praise and support to the achievements in China’s chemical technology and equipment sector. **********************[A Decade of Progress in Chemical Equipment] A continuously updated summary thread; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** On October 29, 2019, the 4,000 tons per day multi-nozzle gasification furnace at Yanzhou Coal Industry Ordos Energy Chemical Rongxin Chemical Co., Ltd. was successfully put into operation. This device is the world’s first gasifier of its kind that can process coal on a large scale, marking another significant advance in China’s large-scale coal gasification technology. A responsible official from the company stated that the company’s annual production capacity for coal-based ethylene glycol is 400,000 tons, while that for polydimethyl methoxymethane (DMMn) is 300,000 tons. The total investment required for this circular economy demonstration project amounts to 7.68 billion yuan. The project was launched in November 2017 under an EPC turnkey contract model. Building on the first-phase coal-to-methanol project, this initiative involves scaled-up construction in phases two and three to extend the coal chemical industry chain, ultimately establishing a coal chemical demonstration base capable of producing 5 million tons of coal-to-methanol per year as well as a range of downstream fine chemical products. The project employs multi-nozzle gasification technology, and its main construction components include 3 water-coal slurry gasifiers with a capacity of 4,000 tons per day, purification units, sulfur recovery units, an ethylene glycol plant with an annual production capacity of 400,000 tons, a DMMn plant with an annual production capacity of 300,000 tons, and 2 air separation units with a capacity of 92,000 standard cubic meters per hour each.
The HuiNeng coal-to-natural gas project is located in the Shengyuan Coal Chemical Industry Base in Yijinhuoluo Banner, Ordos City. The project produces synthetic natural gas and liquefied natural gas using coal as raw material; it is the first demonstration project for coal-to-natural gas in the country to be funded and built by a private enterprise. The construction of this project is carried out in two phases: Phase 1 required an investment of around 7 billion yuan; it began operations in October 2014, with all 400 million cubic meters of natural gas being liquefied ； The second-phase natural gas liquefaction project (LNG) is a load-driven natural gas liquefaction plant. The planned investment for this project is 12 billion yuan; the construction will include natural gas purification, liquefaction, storage of liquefied natural gas, transportation, as well as related supporting facilities. It will enable an additional production capacity of 1.6 billion cubic meters of coal-derived natural gas, all of which will be liquefied, with a processing capacity of 2.7 million cubic meters of natural gas per day.
News came from the site of the second phase of the coal-to-natural gas project at Inner Mongolia HuiNeng Coal Chemical Co., Ltd. (referred to as “HuiNeng”). The super-large multi-nozzle opposed water-coal slurry gasification unit, capable of processing 4,000 tons of coal per day per furnace, which was developed jointly by our university and Yankuang Group Co., Ltd. (Shandong Energy Group Co., Ltd.), successfully carried out its first feeding operation at 12:35 on September 7, 2021. Designed with a maximum gas production capacity of 247,500 Nm3/h (CO+H2), it is the gasifier with the highest operating gas production capacity among those in use internationally at present. The successful commissioning of the HuiNeng Phase II coal-to-natural gas project marked the first application of our university’s coal gasification technology in the field of coal-to-natural gas production. This project involves the construction of 3 multi-nozzle opposed water-coal slurry gasifiers with a pressure of 6.5 MPa and a diameter of 4000 mm (2 in operation and 1 as backup). This type of furnace is an ultra-large-scale gasification furnace (capable of processing 4,000 tons of coal per day per unit) developed as part of a key research and development project under the **13th Five-Year Plan**, undertaken by our university and Yankuang Group Co., Ltd. It is currently the largest operating coal-water slurry gasification furnace in the world in terms of unit size. This successful commissioning also marks the first time that this super-large gasifier has been successfully applied outside of a demonstration facility. With the establishment of China’s goals for carbon peak and carbon neutrality, the clean and efficient utilization of coal is a top priority for energy conservation and emission reduction. The enlargement of the gasifier, the core unit in modern coal chemical plants, is one of the effective ways to improve energy utilization efficiency and reduce the total investment in such projects. Since the operation of the first 1,000-ton-class demonstration unit for multi-nozzle opposed water-coal slurry gasification in 2005, our university has been at the forefront of international research and development in the area of scaling up gasification facilities. We have successively achieved advancements from a capacity of 1,000 tons of coal processed per day per furnace to 2,000 tons, 3,000 tons, and 4,000 tons. To date, a total of 197 gasification units from 66 projects have been promoted and put into use; 37 of these projects are currently in operation, with 102 gasification units operational. This has effectively promoted the transformation and upgrading of China’s energy and chemical industries, laying a technical foundation for achieving the dual-carbon goals at an earlier date.
