Hualu’s technology for treating wastewater and exhaust gases from coal gasification has been included in the 2022 Directory of Suitable Technologies for Green Chemical Parks. Author/Source: Gasification World. Date: May 12, 2023. Clicks: 27. It was recently reported that the “technology for pre-treatment and comprehensive utilization of wastewater and exhaust gases from coal gasification,” developed independently by Hualu Engineering Technology Co., Ltd., has been successfully included in the China Petroleum and Chemical Industry Federation’s 2022 Directory of Suitable Technologies for Green Chemical Parks. “The \"Pre-treatment and Comprehensive Utilization Technology for Gasification Wastewater and Exhaust Gases\" achieves a pH level of around 8.3 in the graywater system through process improvements and optimizations, thereby significantly reducing the likelihood of scaling in the equipment and pipelines of this system. It also enables the utilization of waste heat from high-pressure and medium-pressure flash steam, which greatly improves the overall energy efficiency of the facility. This technology plays a positive role in facilitating the efficient utilization of coal resources in our country, promoting technological advancement in the coal chemical industry, and helping traditional coal chemical enterprises to save energy, reduce carbon emissions, and improve efficiency. As one of the first international engineering companies in China to enter the coal chemical industry, Hualu Engineering Technology Co., Ltd. has completed the design and technical services for nearly 80 large-scale coal chemical projects. It deals with a wide range of coal gasification technologies, offers various gasification pressures and furnace specifications, and has achieved numerous breakthroughs in this field.
