China: ECH-G Plant KVT Bags Technology Contract for World’s Largest Epichlorohydrin Unit
Haiwan Chemical has awarded a technology contract and license agreement to KVT for the world´s largest Glycerine based Epichlorohydrin production complex. Scheduled to be built in Qingdao, China, KVT will license its Epiprovit closed loop technology to the facility.
Graz/Austria – Kanzler Verfahrenstechnik (KVT) has signed a major technology contract and license agreement for the delivery of the world´s biggest Glycerine based Epichlorohydrin production complex to be built in Qingdao, Shandong, China. KVT has announced that it has been awarded a contract by Qingdao Haiwan Chemical Co. (Haiwan Chemical) to license KVT's leading Epiprovit closed loop technology for a new Epichlorohydrin production plant.
Under the terms of the contract, KVT will provide the technology license, process design package, key equipment as well as technical and training services to Haiwan Chemical for building a greenfield 150,000 tons per year ECH-G plant in Shandong Province in China.
The Epichlorohydrin unit is supported by a 200.000 tons per year Glycerine refining unit and the related treatment unit for purification and recycling of waste brine resulting from saponification.
KVT has implemented the concept of green chemistry and circular economy into its design principles by utilizing renewable feedstocks and securing the internal reuse and recycling of waste streams. The Epiprovit cycle reflects this concept by utilizing crude Glycerine, a waste stream from the biodiesel production and excess Chlorine from Chlor-Alkali Units, for the production of Epichlorohydrin. The waste brine streams resulting from Glycerine and Epichlorohydrin production are purified in the integrated Seabrine unit and completely recycled to the Chlor-Alkali unit as feedstock for the production of Caustic Soda and Chlorine.
Compared to the conventional fossil-based route, the Epiprovit concept leads to a 50 % increase of renewable feedstock in Epichlorohydrin production, a ten-fold reduction in waste water generation and a significant reduction in CO2 emissions. Besides that, the generated waste water can be directly recycled and reused for the production of Caustic Soda and Chlorine without further treatment.
