To help meet new regulations governing wastewater treatment at Chinese coal-to-chemical plants, a facility in Yulin City will install GE’s zero liquid discharge (ZLD) technology. GE’s ZLD evaporator and crystallizer system will reportedly eliminate liquid discharge of waste and enable water reuse at the Shaanxi Future Energy Chemical Co., Ltd. coal-to-chemical plant in Shaanxi Province, China.
Under China’s new regulations, including the Water Pollution Action Plan, the New Environmental Protection Law and China’s 13th Five-Year Plan, coal-fired power plants must eliminate the liquid discharge of wastewater into the environment and a ZLD system must be installed to obtain a permit for these plants. The Hongdun facility is a coal-to-liquid project where Shaanxi Future Energy Chemical converts coal into a variety of oil products
GE’s wastewater treatment system includes a vapor recompression brine concentrator followed by a crystallizer. The equipment should be delivered in mid-2016, with commissioning in March 2017, according to the company. Once operational, the HongDun Wastewater Treatment Facility will reportedly treat wastewater feed at a rate of 40 m3/hr.
