Comprehensive review of drawings for 600,000-ton/year coal-based ethylene glycol production at Sanning Chemical Industry – Author/Source: Huahua Network, Coal Chemicals Sector; Date: 2018-07-16; Clicks: 2. On June 28th, a meeting to review the equipment drawings for the gasification section of Sanning Chemical Industry Co., Ltd.’s project aimed at adjusting the raw material structure for ammonia production and producing 600,000 tons/year of ethylene glycol was held at China Wuhuan Engineering Co., Ltd. The meeting mainly reviewed the drawings for equipment such as gasifiers, water scrubbers, evaporative hot water towers, lock hoppers, and cyclone separators. The designers at Wuhuan Company provided technical explanations regarding the design concepts of the equipment drawings and the key points that needed attention during the construction process. The equipment manufacturing unit and the company’s technical staff suggested modifications to some of the unreasonable design elements. It is understood that this review meeting for the equipment drawings in the gasification area is the first of its kind for the entire ethylene glycol project. Its purpose is to improve the design drawings through reviews conducted by the design team, the manufacturing team, and the construction team, thereby enabling the manufacturing team to produce high-quality equipment. At present, the construction drawings for the equipment in various areas have been gradually completed, and drawing reviews are also set to begin in full scale to ensure the quality of project construction. The Hubei Sanning Ammonia Synthesis Raw Material Structure Adjustment and 600,000 tons/year Ethylene Glycol Production Project (Phase I) is based on the 520,000 tons/year ammonia production capacity of Sanning Company’s urea plant and Tiantian Company’s plants. Without increasing this capacity, the existing urea production facilities that use bituminous coal as raw material and rely on atmospheric-pressure batch fixed-bed gasifiers, atmospheric-pressure desulfurization processes, and high-pressure ammonia synthesis, as well as the downstream urea and ammonium bicarbonate production units, are to be phased out. A new facility will be built using Shenhua’s high-quality coal as raw material to produce 400,000 tons per year of ethylene glycol and 520,000 tons per year of synthetic ammonia ； Using sulfur as raw material, 800,000 tons per year of industrial-grade sulfuric acid is produced. The total investment for the project is 7.5 billion yuan. In April 2017, Hubei Sanning Chemical Co., Ltd. and China Wuhuan Engineering Co., Ltd. signed a contract for design, overall management, and technical services regarding the \"project to adjust the raw material structure for ammonia synthesis and produce 600,000 tons per year of ethylene glycol.\" On February 9, 2018, the groundbreaking ceremony for Hubei Sanning Chemical Co., Ltd.’s project to adjust the raw material structure for ammonia production and to produce 600,000 tons per year of ethylene glycol was held in the Yaojiagang Chemical Industrial Park in Zhijiang City. The total estimated investment for the project is 10 billion yuan, with a planned construction period of 24 months; completion and operation are expected by December 2019. The project utilizes Yankuang’s pressurized gasification of water-coal slurry, with the core process being the technology for producing ethylene glycol from high-purity chemical synthesis gas. Donghua Institute is responsible for the overall project management, and a contract for the air separation unit was also signed with Air Liquide. Hubei Sanning Chemical Co., Ltd. was formerly known as Zhijiang County Fertilizer Factory, and was established in 1970. In 1993, it was restructured as a state-controlled joint stock company on a pilot basis, and in 2001 its ownership was privatized through the \"two swaps\" reform. In 2007, it came under the control of Shanxi Jincheng Anthracite Coal Industry Group Co., Ltd., a large state-owned enterprise.
