Sedin Engineering Co., Ltd.

Sedin Engineering Co., Ltd. (SEDIN) is a Chinese engineering company headquartered in Taiyuan, Shanxi Province, and a wholly owned subsidiary of China National Chemical Engineering Co., Ltd. (CNCEC), the listed arm of the state-owned China National Chemical Engineering Group. Founded in 1958, Sedin describes itself as a national high-tech enterprise whose core business is engineering design and engineering, procurement and construction (EPC) contracting, supported by research and development capabilities. It holds a Grade A comprehensive engineering design qualification issued by China's Ministry of Housing and Urban-Rural Development, the highest level in the Chinese engineering construction sector, along with qualifications in engineering consulting, supervision, tendering, geotechnical investigation, environmental impact assessment, pressure vessels and pressure piping. The company is best known for its leadership in coal chemical engineering. It states that it was the first Chinese engineering company to introduce coal-to-natural-gas (SNG) technology projects and that it has undertaken the engineering design, EPC contracting and technical services for all coal-to-SNG projects under construction in China. Its proprietary technologies include crushed coal pressurized gasification and low-temperature methanol wash purification. Sedin also claims internationally leading positions in MTG (methanol-to-gasoline), phenol/acetone, TDI and coke-oven-gas-to-methanol technologies, and high market share in coal-to-SNG, coking engineering, tar deep processing, nitric acid, ammonium nitrate, polysilicon, ethylene oxide, aniline and polyoxymethylene technologies. Sedin's engineering scope covers coal chemicals, organic chemicals and synthetic materials, coal coking and by-product processing, methane-rich gas and natural gas utilization, nitric acid and ammonium nitrate, ammonia and urea, nitrobenzene and aniline projects, power engineering, petroleum and chemical storage, environmental engineering and municipal engineering. It has completed more than 1,500 large and medium-sized domestic and international key construction projects and has received more than 200 national, ministerial and provincial awards for excellent design and scientific and technological progress. Since 2005 it has consistently ranked among China's Top 100 Engineering Survey and Design Enterprises. The company employs more than 1,200 people, including one national engineering design master, four petroleum and chemical industry engineering survey and design masters, over 440 senior professional title holders, and more than 260 personnel holding qualifications such as first-class structural engineer, first-class architect, national supervision engineer, first-class construction project manager, cost engineer, safety engineer and registered consulting engineer. Sedin has pursued strategic transformations, including the establishment of a Ministry of Chemical Industry coal chemical design technology center in 1986, a market-oriented diversification strategy in 1999, and a 2015 partnership with Siemens to develop Industry 4.0 solutions for the coal chemical sector, alongside the establishment of offices in Indonesia and India. It maintains international business contacts and has participated in projects in countries such as Vietnam and Kazakhstan.

Sedin Engineering Co., Ltd. was founded in 1958, according to its official company profile. It describes itself as a national high-tech enterprise recognized in 2006 and was restructured into a wholly state-owned one-person limited liability company in 2008. In 2011, it obtained the Grade A comprehensive engineering design qualification from China's Ministry of Housing and Urban-Rural Development, the highest-level qualification in the engineering construction field. The company is a wholly owned subsidiary of China National Chemical Engineering Co., Ltd. (CNCEC), with registered capital of 1.5 billion yuan. The company's development has included several strategic transformations. In 1986, it established a coal chemical design technology center under the Ministry of Chemical Industry, marking its first strategic transformation. In 1999, it implemented a second strategic transformation with a strategy of "facing the market, diversified operations, strengthening the main business, and extending to both ends." In 2015, it pursued a third strategic transformation by partnering with Siemens to create Industry 4.0 solutions for the coal chemical sector, and it established offices in Indonesia and India. Sedin has built a comprehensive engineering service system covering technology research and development, technical consulting, engineering design, procurement and construction, project management and general contracting. It has completed more than 1,500 large and medium-sized domestic and international key construction projects and has received more than 200 national, ministerial and provincial awards for excellent design and scientific and technological progress. Since 2005, it has consistently been ranked among China's Top 100 Engineering Survey and Design Enterprises. In the coal-to-natural-gas field, Sedin states it was the first domestic engineering company to introduce coal-to-SNG technology projects and that it has undertaken the engineering design, EPC contracting and technical services for all coal-to-SNG projects under construction in China. Notable projects include the Xinjiang Qinghua Energy Group 5.5 billion cubic meters per year coal-to-SNG project, the Inner Mongolia Datang International Keshiketeng 4 billion cubic meters per year coal-to-SNG project, the Liaoning Datang International Fuxin 4 billion cubic meters per year coal-to-SNG project, and the Xinwen Mining Group Yili 2 billion cubic meters per year coal-to-SNG project. These projects use Sedin's proprietary crushed coal pressurized gasification technology and low-temperature methanol wash purification process. The first phases of the Xinjiang Qinghua and Inner Mongolia Datang Keshiketeng coal-to-SNG projects were put into operation in 2013. Sedin's technology portfolio also includes internationally leading positions in MTG, phenol/acetone, TDI and coke-oven-gas-to-methanol technologies, and high market share in coal-to-SNG, coking engineering, tar deep processing, nitric acid, ammonium nitrate, polysilicon, ethylene oxide, aniline and polyoxymethylene technologies. It has completed more than 60 nitric acid plant designs and EPC projects of various scales, and has worked on major ammonia and urea projects including the Guodian Chifeng coal chemical phase one project with 300,000 tons per year of synthetic ammonia and 520,000 tons per year of urea, the Yunnan Dawei ammonia project with 500,000 tons per year of synthetic ammonia, the Vietnam Chemical Corporation Ninh Binh coal-to-ammonia/urea project, and the Shenhua Ningmei GSP gasification unit, China's first large-scale pulverized coal pressurized gasification unit, which was designed by Sedin and put into operation in 2011. In the nitrobenzene and aniline field, Sedin worked on the Ningbo Wanhua project with 270,000 tons per year of nitric acid, 480,000 tons per year of nitrobenzene and 360,000 tons per year of aniline. In environmental engineering, Sedin obtained an environmental impact assessment certificate from the former State Environmental Protection Administration in 1991. Its current qualification is Grade B, covering chemical, petrochemical and pharmaceutical, light industry, textile and chemical fiber, and general project report forms. It has 24 full-time environmental impact assessment personnel, including three professor-level senior engineers, ten senior engineers and four engineers, with 14 holding environmental impact assessment professional qualification certificates. It also has one construction project assessment expert from the Ministry of Environmental Protection's assessment center and several provincial assessment experts. In more recent years, Sedin has continued to undertake major coal chemical and petrochemical projects in China and abroad. Its news center reports on projects such as the Xinjiang Xinye coal-to-natural-gas project, the Zhundong 2 billion cubic meters per year coal-to-natural-gas project, the Xinjiang Zhongrong chemicals project, the Datang Keshiketeng 70,000 tons per year crude phenol refining project, and the Enchuan nano-silica new materials project.
