Project to Demonstrate Clean and Efficient Conversion of Coal by Differentiation – Pyrolysis Phase of Yulin Chemical’s Project; Author/Source: Huahua Net Coal Chemicals; Date: June 22, 2020; Clicks: 70. At 17:05 on June 17, the pouring of concrete for the first batch of materials used in constructing the large-scale foundations for the pyrolysis phase of Yulin Chemical’s project, which has a capacity of 15 million tons per year for clean and efficient conversion of coal by differentiation, began. This represents another important milestone in the construction of this project, following the completion of the construction of secondary piping systems across the entire plant. What is being poured this time is the foundation slab for the coal grinding frame of the pyrolysis startup project’s coal pyrolysis unit. This frame is 70 m high; the portion below 53.5 m is made of concrete, with a required concrete volume of around 12,000 cubic meters. This constitutes a key task on the critical path for the project’s construction. All members of the Pyrolysis Project Initiation Department at Shengbang Technology Co., Ltd. have been actively preparing since early June. Working in close collaboration with Sinochem Third Construction, the contractor responsible for the construction of the coal powder pyrolysis unit, they overcame various challenges. With strong support from the Yulin Chemical 120 project team and the supervision unit, they created favorable conditions for the construction of the coal grinding frame foundation, resulting in positive progress in the project’s development. The pyrolysis phase of the 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products at Yulin Chemical, belonging to Shaanxi Coal Group, is under the general contracting management of Shengbang Technology Co., Ltd. It includes a coal pyrolysis unit with a capacity of 1.2 million tons per year (based on the dry weight of raw coal), a catalyst production unit with a capacity of 35,000 tons per year, a suspended-bed hydrogenation unit with a capacity of 500,000 tons per year, as well as a combined hydrogenation unit for hydrogen supply solvents and light oil (including a unit for producing hydrogen supply solvents with a capacity of 270,000 tons per year and a unit for hydrogenation to improve product quality with a capacity of 400,000 tons per year). There is also a gas desulfurization unit, a process wastewater treatment unit with a capacity of 420,000 tons per year, as well as coal pyrolysis tanks and related supporting facilities. This project is constructed simultaneously with Yulin Chemical’s first-phase ethylene glycol plant with an annual production capacity of 1.8 million tons. It utilizes Shengbang Technology’s own patented pyrolysis technology, and is scheduled to be completed and put into operation in June 2021. To date, aside from the complete construction of the foundations for the coal grinding frames in the coal pyrolysis unit, the foundation reinforcement work for 6 storage tanks in the raw material and finished product tank areas has been completed. For 3 of these 5,000-cubic-meter storage tanks, the formwork for their foundations has been set up, and concrete pouring as well as tank installation are about to begin ； Except for some areas restricted by factors within the site, the secondary ground pipelines across the entire plant have been basically installed and backfilled ； Excavation work will soon begin on the system utility tunnels and the main roads within the plant.
