【Ten Years of Rapid Development in Chemical Engineering Equipment】Utilization of Low-Rank Coal through Rotating Bed Low-Temperature Pyrolysis at a Capacity of 5 million tons per year from 2011 to 2023
Thread Content
Looking at the development of chemical engineering technology over the past decade, we celebrate the prosperity and strength of modern China. This is just a starting point to encourage further discussion among everyone; with more participants, the discussions will be even more lively. HAICHUAN becomes even better with you here. [A comprehensive overview of the ten-year development of chemical engineering equipment] – updates are available regularly. Feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. Prevention first, life above all. ----------------------------------------- The Longcheng series of technical equipment for the low-temperature pyrolysis and selective utilization of low-grade coal, with an annual processing capacity of 5 million tons, has been included in the **third batch of major technical equipment projects in the energy sector**. In order to promote the demonstration and application of such major technical equipment in the energy field, accelerate innovation in this area, and ensure the security of the supply chains related to key technical equipment, on October 24th, the **Energy Administration issued Announcement No. 6 for 2023**, which listed the projects belonging to the third batch of major technical equipment in the energy sector. The Longcheng series of equipment was successfully selected as the only project in the category of selective utilization of low-grade coal. The first set of major technical equipment in the energy sector refers to those key technical devices in this field that have achieved significant technological breakthroughs in China, possess independent intellectual property rights, and have not yet seen widespread market adoption; these include the first three sets or batches of such equipment, complete machines and their core components, control systems, basic materials, software systems, etc. The Longcheng Dan series of 5 million tons per year low-rank coal rotary bed equipment is a technological system for the selective utilization of materials obtained through low-temperature pyrolysis. After low-temperature pyrolysis of low-rank coal, it enables efficient conversion of the resulting materials into coal, oil, gas, and chemicals on a selective basis. This equipment boasts advantages such as strong adaptability to different feedstocks, high yields of oil and gas, good product quality, and large scale per unit. Additionally, it overcomes three major technical challenges related to pyrolysis: high-temperature rotary dynamic sealing, intelligent temperature control for staged heating, and the recovery of solid particles larger than 4 microns along with the separation of oil and gas. Currently, this equipment is part of the Xinjiang HuiNeng 15 million tons per year coal clean and efficient utilization project.
Xinjiang 15 million tons/year coal grading, quality differentiation, and hierarchical utilization project. The main components of this project include a coal pyrolysis unit with a capacity of 15 million tons per year, a facility for the comprehensive utilization of coal decomposition gases to produce hydrogen along with liquefied natural gas as a by-product, a combined unit for the lightening of coal tar with a capacity of 1.5 million tons per year (including a coal tar hydrogenation unit with a capacity of 1.5 million tons per year and a coal-based distillate oil dehydrogenation unit with a capacity of 400,000 tons per year), as well as production support facilities. The project utilizes the clean, efficient, and comprehensive utilization technology for the fractional conversion of low-temperature low-rank coal via a rotary bed, which was developed independently by Henan Longcheng Group. In addition to producing upgraded coal, the coal decomposition gas generated is processed to yield coal tar and hydrogen; simultaneously, LNG, LPG, condensate oil, and sulfur are also produced. Through the hydrogenation of coal tar, naphtha, lightened coal tar 1#, and hydrogenation tail oil are produced, and naphtha is further processed via a coal-based distillate dehydrogenation unit to yield benzene and C7+ distillates. Xinjiang HuiNeng Coal Clean and Efficient Utilization Co., Ltd. is a wholly-owned subsidiary of Beijing LongCheng HuiNeng Technology Co., Ltd., which in turn is part of Henan LongCheng Group Co., Ltd. The company was established in May 2021 in Yiwu County, Hami City, Xinjiang. After years of development, it has grown into a modern enterprise group that spans multiple industries such as special steel, the graded and quality-based utilization of coal, machinery manufacturing, steel structures, and metallurgical materials. It employs over 10,000 people, has total assets of 23.8 billion yuan, and oversees more than 20 wholly-owned subsidiaries as well as 4 holding companies.

“\"Clean and efficient utilization,\" \"graded and quality-based utilization,\"... No matter how fancy the wording is, it cannot change the fact that the project itself is characterized by being \"high in energy consumption, high in emissions, and resource-intensive.\"
