To help meet new regulations governing wastewater treatment at Chinese coal-to-chemical plants, a facility in Yulin City will install GE’s advanced zero liquid discharge (ZLD) technology.

The ZLD evaporator and crystallizer system will 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.

China is one of the world's largest producers of coal, and coal-fired power plants provide the majority of the country’s electricity. Coal also serves as a vital feedstock and is converted into a wide variety of chemical and petroleum products.

Under China’s new regulations, including the Water Pollution Action Plan, the New Environmental Protection Law and China’s 13th Five-Year Plan, these 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, providing a proven and cost-effective ZLD solution.

The equipment is expected to be delivered in mid-2016, with commissioning in March 2017. Once operational, the HongDun Wastewater Treatment Facility will treat wastewater feed at a rate of 40 m3/hr.
