Yuneng Chemical signed a contract with Hangzhou HollySys. Author/Source: Energy & Chemicals News. Date: November 15, 2021. Click-through rate: 10. Recently, Shaanxi Yuneng Chemical Materials Co., Ltd., a subsidiary of Shaanxi Yulin Energy Group, signed a contract with Hangzhou HollySys Automation Co., Ltd. regarding the procurement of a distributed control system and gas detection system for its 400,000-ton/year ethylene glycol project, which is part of the larger 1.2 million-ton/year coal-to-ethylene glycol project. Hollyland will provide an integrated solution based on the DcS+GDS system for the entire process of the joint plants in this project, enabling integrated control of all units, from utility systems to main processes such as gasification and ethylene glycol production. It is reported that this marks the first application of HaliCo’s gasification technology in a practical setup, following the establishment of a simulation laboratory jointly by HaliCo and Collin. The project construction includes a gasification unit, a purification unit, an H2/CO separation unit, an ethylene glycol unit, etc. The utility systems and supporting auxiliary facilities include: 3×350 t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30 MW extraction-backpressure steam turbine generator sets, six sets of 60,000 Nm³/h air separation units, a circulating water station, a demineralized water station, storage and transportation facilities, a sewage treatment plant, etc. The gasification unit employs the Corin powder gasification technology and includes 2 powder gasifiers. The first phase of the project to produce 400,000 tons per year of ethylene glycol via coal conversion at Shaanxi Yulin Energy Group Co., Ltd., with a capacity of 120,000 tons per year, is part of the initiatives undertaken by Yulin Energy Group in the Clean Fuel Production Base and High-End Chemical Materials Base located in the Qingshui Industrial Park of the Yushen Industrial Zone. The total planned land area for this project is 711 mu, with an estimated investment of 6 billion yuan; the construction period is set at 30 months, and completion and operation are scheduled for 2022. The project construction includes a gasification unit, a purification unit, an H2/CO separation unit, an ethylene glycol unit, etc. The utility systems and supporting auxiliary facilities include: 3×350 t/h high-temperature and high-pressure circulating fluidized bed boilers + 2×30 MW extraction-backpressure steam turbine generator sets, an air separation unit, a circulating water station, a demineralized water plant, storage and transportation facilities, a sewage treatment plant, etc. The gasification unit employs the Corning powder gasification technology and includes 2 powder gasifiers; the ethylene glycol unit uses the Zhongke Yuandong ethylene glycol technology. Carbon monoxide and hydrogen are used to indirectly synthesize ethylene glycol through carbonylation, coupling, and hydrogenation, with by-products including dimethyl carbonate, crude ethanol, mixed alcohols, sulfur, liquid oxygen, and liquid nitrogen.
