[Ten years of major development in chemical technology] 021-2023 Energy-saving technology coupled with low-temperature and high-efficiency distillation of DMF wastewater and two-stage MVR compressor
Thread Content
The "low-temperature and high-efficiency distillation of synthetic leather DMF wastewater coupled with two-stage MVR compressor energy-saving technology" developed by Shaanxi Blower (Group) Co., Ltd. was recently listed on the list of the Ministry of Ecology and Environment,* * The National Development and Reform Commission and the Ministry of Industry and Information Technology compiled * * Catalog of advanced technologies for cleaner production. This is the only one selected in Shaanxi Province * * Advanced technologies for cleaner production will be promoted to the whole society. According to reports, based on its advantages in distributed energy solutions and the strength of the "Energy Interconnection Island" smart green system solution, Shaangu innovatively adopted a new process technology route of low-temperature high-efficiency distillation and two-stage MVR (steam mechanical recompression technology) compressors in series and coupling the distillation process with green energy-saving recovery, which will contain DMF. Wastewater is distilled and separated, and the steam generated after waste resource treatment is reused in the distillation system, filling the domestic gap. It has built the industry's largest single set of processing capacity of 100 tons/hour DMF wastewater treatment integrated recovery device, achieving centralized recovery of DMF wastewater in Lishui Synthetic Leather Park, multi-energy complementation and zero discharge.
[Ten years of major development in chemical technology] The technical feasibility of ammonia-incorporated combustion in coal-fired units to achieve carbon reduction targets from 020 to 2023 has been verified https://bbs.hcbbs.com/thread-3597305-1-1.html (Source: Huahaichuanliu-Haichuan.com)
Ammonia-incorporated combustion technology in coal-fired units is regarded as an important way to achieve carbon emission reduction goals. Recently, China University of Petroleum (East China) and Shandong Electric Power Company jointly carried out technical feasibility verification work on ammonia-incorporated combustion in coal-fired units and achieved preliminary results. Experimental results show that on the premise of ensuring combustion efficiency, ammonia-doped combustion can significantly reduce NOx emissions, and at the same time, CO2 emissions can also be effectively controlled. This technology will help promote the coal-fired power industry to achieve carbon emission reduction targets faster and enhance the competitiveness of coal-fired power generation enterprises. .

Low-temperature high-efficiency distillation and two-stage MVR (steam mechanical recompression technology) compressors are coupled in series with the distillation process to create a new green and energy-saving recycling process technology route. DMF-containing wastewater is distilled and separated, and the steam generated after the waste is recycled into the distillation system fills the domestic gap.
