Xinjiang Tianye’s ethylene glycol project: Jinhua Furnace 3.0 operates at high efficiency for 130 days in a row, setting another record Author/Source: Jinhua Furnace Date: 2021-12-14 Clicks: 19 On December 14, Unit 2 gasification furnace (Jinhua Furnace 3.0) of Xinjiang Tianye Group Co., Ltd.’s plant with an annual production capacity of 600,000 tons of ethylene glycol operated at high efficiency and steadily for 130 days in a row, breaking the previous record held by Unit 3, which had operated for 111 days; this marks another new world record for such gasification furnaces. This achievement is a significant milestone in the application of large-scale water-coal slurry gasification technology worldwide. It signifies that the domestically developed “Jinhua Furnace 3.0” gasification technology has taken another major step forward on its journey to becoming a global leader. The 600,000-ton-per-year ethylene glycol project of Tianye Group utilizes the “Jinhua Furnace 3.0” gasification technology. Each furnace can handle approximately 1,500 tons of coal per day, with an operating pressure of 6.5 Mpa. It represents a highly efficient combination of “coal slurry, water-cooled walls, and a radiant steam generator”. To ensure the optimal performance of the \"Jinhua Furnace 3.0\" system, a coal blending database was established, **improving the furnace’s adaptability to different types of coal, and enabling reliable switching between three operating units and one standby unit as well as stable operation of the Jinhua Furnace 3.0. It has broken the foreign monopoly on the technology for recovering waste heat from syngas in coal-water slurry gasifiers; it is currently a leading-edge, environmentally friendly, and highly efficient gasification unit in the industry. Project Overview: Xinjiang Tianye Huihe New Materials Co., Ltd. uses locally sourced coal from Xinjiang as raw material to produce ethylene glycol in the Shihutan New Materials Industrial Park (Unit 147) in Shihezi City, Xinjiang. There are a total of four sets of 6.5MPa Jinhua furnace 3.0 gasification units, operating in a three-in-one-backup configuration; each furnace produces 100,000 Nm3/h of usable gas (CO+H2). The waste heat from the gasification furnaces generates 9.8MPa G saturated steam, which is fed into the pipeline network. Construction began in August 2017, and the project was completed with construction and commissioning finished in July 2020, meeting the conditions for starting up chemical production. The Jinhua Furnace 3.0 gasification unit was successfully ignited on July 28, and coal water slurry was fed successfully on July 29, resulting in the production of useful gases (CO+H2).
