Signing of EPC Contract for Wastewater Treatment of Yunnan Pioneer Chemical’s Coal-to-Oil Project Author/Source: Huahua Network, Coal Chemicals Date: 2018-04-23 Clicks: 41 Recently, the EPC project for wastewater treatment of Yunnan Pioneer Chemical Co., Ltd.’s pilot project for the clean utilization of lignite was signed in Kunming. Leaders and experts from both parties, including Luo Biao, General Manager of Yunnan Pioneer Chemical Co., Ltd., Xu Yu, Deputy General Manager, Sun Wenquan, General Manager of Nanjing University of Technology Environmental Technology Co., Ltd., and Dr. Lu Xi, attended the contract signing ceremony held in Kunming, Yunnan. Luo Biao, General Manager of Pioneer Chemicals, and Sun Wenquan, General Manager of Nanjing Engineering Environment, signed the agreement on behalf of their respective parties at the ceremony. Yunnan Pioneer Chemical Co., Ltd. is a large state-owned enterprise under the Yunnan province. To promote the clean and comprehensive utilization of lignite resources in Yunnan, Pioneer Chemical invested 4.525 billion yuan in the Jinsuo Industrial Park in Xundian County, Kunming, to build the \"Pioneer Lignite Clean Utilization Pilot Project\", which features a coal-to-oil facility with an annual production capacity of 470,000 tons in terms of oil equivalent. Since its commissioning in 2014, the Pioneer Chemicals project has strived to achieve compliant emissions of waste gas and a \"zero discharge\" target for wastewater, achieving relatively significant results. However, due to the high toxicity and difficulty in degradation of the gas, water, and wastewater generated by this project, existing wastewater treatment processes are unable to meet the new environmental requirements. To completely eliminate the problem of foul odor pollution during the production process, Pioneer Chemical decided to shut down the plant for repairs. In December 2016, Pioneer Chemical commissioned Nanjing University of Technology Environmental Science & Technology Co., Ltd. and Nanjing University of Technology to develop a plan for environmental remediation at Pioneer Chemical. Through repeated tests and verifications, it was determined that the main sources of waste gas at Pioneer Chemical were volatile organic compounds present in wastewater, as well as foul-smelling gases generated during wastewater treatment. LNG Environment, leveraging its years of experience in developing mature process technologies and extensive engineering implementation skills in the field of wastewater treatment for the coal chemical industry, and taking into account the technical challenges associated with Pioneer Chemical’s phenol-containing wastewater – such as high concentrations of COD, ammonia nitrogen, total phenols, and volatile phenols, high biological toxicity, unstable quality of the coal used as raw material, and significant variations in water quality – has proposed solutions such as classified collection, treatment based on water quality characteristics, and hierarchical reuse to optimize water quality balance. We will fully cooperate with Pioneer Chemical in the renovation of the project facilities to enable the plant to resume operation and production as soon as possible. The successful signing of this contract marks the official launch of the Pioneer Chemical Wastewater Treatment Project. The successful implementation of this project will effectively ensure zero wastewater discharge and compliance with standards for exhaust gas treatment, thereby resolving the environmental issues within the factory premises and in the surrounding area that have plagued the enterprise for many years. It holds significant demonstrative value for the treatment of high-concentration wastewater in industries related to the clean utilization of lignite. Yunnan Pioneer Chemical Co., Ltd. was established on September 24, 2009, with a registered capital of 1.25 billion RMB. Its two major shareholders are Yunnan Jiehua Clean Energy Development Co., Ltd. and Yunnan Provincial Industrial Investment Holding Group Co., Ltd. Pioneer Chemical uses lignite as raw material to produce products such as methanol, gasoline, and liquefied natural gas; it is the largest investment attraction project in Xundian County, Yunnan Province. In March 2014, the 200,000 tons per year methanol-to-gasoline (MTG) industrial demonstration plant of Yunnan Pioneer Chemical Co., Ltd. successfully completed its trial operation with a single batch of feedstock and began operating at full capacity, becoming the fifth industrial demonstration project for \"coal-to-oil\" conversion in China to operate successfully. This facility is the largest methanol-to-gasoline conversion plant in operation in China, and it pioneered the \"one-step methanol-to-gasoline conversion\" technology.
