To help meet new environmental regulations governing wastewater treatment at Chinese coal-to-chemical plants, a facility in Yulin City will install General Electric’s advanced zero liquid discharge (ZLD) technology.
GE’s ZLD evaporator and crystallizer system will eliminate liquid discharge of waste and enable water reuse at the Shaanxi Future Energy Chemical Co. coal-to-chemical plant in Shaanxi Province, China.
The ZLD market, estimated to be worth $200 million, is growing as countries enforce stronger environmental regulations. GE says this ZLD project is the sixth of this kind that the company has completed in China in recent years.
In addition to providing the majority of the country’s electricity, coal 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. GE expects to deliver the equipment 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.
In October, Aquatech won a contract to provide its ZLD water treatment technology for a Chinese coal-to-liquid-fuels conversion project being developed by Shenhua Ningxia Coal Industry, a division of Shenhua Group, China’s biggest coal producer.
