The environmental impact assessment for the fourth coal-to-natural gas project of the year has been approved. Author/Source: Date: 2016-12-12. Clicks: 11. According to a report dated December 9, the environmental impact assessment report for Yili Xintian Coal Chemical Co., Ltd.’s project to produce 2 billion cubic meters of natural gas per year from coal has been approved by the **Ministry of Environmental Protection, under document reference No. Huan Shen [2016] 162. This project became the fourth coal-to-natural gas project to receive approval for its environmental impact assessment in 2016. It is reported that the 2 billion cubic meters per year coal-to-natural gas project in Yili Xintian is now fully prepared for commissioning tests. All joint operation tests have been completed, and commissioning with feedstock is expected to begin this month. On April 25, 2016, the environmental impact assessment report for Inner Mongolia Beikong Jingtai Energy Development Co., Ltd.’s coal-to-natural gas project with an annual production capacity of 4 billion cubic meters was approved ； On April 25, 2016, the environmental impact assessment report for Su New Energy and Feng Co., Ltd.’s project to produce 4 billion standard cubic meters of coal-based natural gas per year was approved ； On March 4, 2016, the environmental impact assessment report for CNOOC’s demonstration project on the clean utilization of low-metamorphic bituminous coal in Datong, Shanxi (CNOOC’s 4 billion cubic meter coal-to-gas project) was approved. Ili Xintian Coal Chemical Co., Ltd. is the developer of the 2 billion cubic meters per year coal-to-natural gas project. It is a state-owned joint venture established through joint investment by Zhejiang Energy Group and Shandong Energy Xinwen Mining Group. The company is located in Yining City, Ili Kazakh Autonomous Prefecture, Xinjiang Uygur Autonomous Region; Zhejiang Energy Group holds 55% of the shares while Xinwen Mining Group holds 45%, with Zhejiang Energy Group exercising control over the company. On June 26, 2015, the **Ministry of Environmental Protection issued the ‘Notice on Not Approving the Environmental Impact Assessment Report for the 2 billion cubic meters per year coal-to-gas project of Yili Xintian Coal Chemical Co., Ltd.’ (Document No. Huanban Han 1046), deciding not to approve the environmental impact assessment report for this project. The project began with site preparation in 2010, the construction of the main structure started in April 2011, and it was essentially completed by 2015. Since the Ministry of Environmental Protection issued a notice on June 26, 2015, denying approval for the environmental impact assessment of the Xintian Coal Chemical Project, construction of the project has essentially come to a halt. On September 30, 2016, the **Ministry of Environmental Protection once again accepted the environmental impact assessment documents for Yili Xintian Coal Chemical Co., Ltd.’s coal-to-natural gas project with an annual capacity of 2 billion cubic meters. Solutions to the issues identified in the Ministry of Environmental Protection’s refusal notice: In response to the problems raised by the Ministry of Environmental Protection and its evaluation center, the project owner has actively carried out renovations in accordance with the latest environmental protection standards; an additional 921,600,000 yuan has been invested in environmental protection measures, on top of the initial investment of 1,844,500,000 yuan. It is planned to construct a rigid temporary storage tank with an effective volume of 210,000 cubic meters on the northeast side of the factory site, north of the sewage treatment workshop, to replace the No. 1 and No. 2 homogeneous soil dam storage tanks in the original plan, **thereby reducing the environmental risks to the Ili River ； The integrated ultrasonic desulfurization and dust removal technology is employed, with 4 flue gas bypass systems for the desulfurization units being removed. The SCR (three-stage catalyst) technology is used for nitrogen oxide removal, and the on-site thermal power plant implements the strictest ultra-low emission standards four years ahead of schedule ； Two new regenerative oxidation units have been installed in the low-temperature methanol washing and gasification areas to capture and treat volatile organic compounds, thereby reducing uncontrolled emissions ； Add 6 sets of dust-containing tar three-phase separation systems ； 1 new sludge drying line with a daily processing capacity of 30 t/d has been added ； At the same time, taking into account the problems that have arisen during the trial production of existing coal chemical enterprises, the process plant area was designed for optimization: The vent gas emitted by approximately 2,000 vent valves is directed to flares or RTO units for treatment, **in order to reduce uncontrolled emissions of waste gases ； Cancel the gasification cold flare; connect the startup exhaust gases to the gasification startup flare ； One additional set of biological deodorization units has been installed; moreover, a photocatalytic unit has been added to these units to improve the removal efficiency of volatile organic compounds ； An additional sulfur recovery unit has been installed to prevent accidental release of acidic gases directly into the acidic gas flare ； The three-tier prevention and control system has been improved; 4 new accident buffer tanks with a total capacity of 39,100 cubic meters have been added. The existing wastewater storage tanks with a capacity of 2.45 million cubic meters are being used as emergency tanks for addressing fire risks in the park. http://img.yf116.cn/image/img/20161212/97413286180.jpg
