Emission Reduction Project- Organic Exhaust Gas Treatment Project In order to fully deal with the harmful temperature of 1100℃, the hazardous solid concentrated solution produced by the MVR waste then undergoes harmless treatment system, Inner Mongolia Company has two without producing additional hazardous liquid waste incinerators. The treatment waste during the process. At the same time, capacity of the liquid waste incinerators is the flue gas generated during incineration 120 tons per day, effectively strengthening will be treated with SNCR denitration , flue the ability to treat harmful concentrated gas quenching device , venturi scrubber and solution harmlessly. The liquid waste wet electrostatic precipitator to reduce the incinerator utilizes natural gas to incinerate amount of air pollutants generated during the concentrated solution at a high the incineration process. Emission Reduction Project-Liquid Waste Incinerator Project To prevent volatile organic solvents used in as 95%. Also, the dust generated in the the production process from being emitted production plants needs to be processed to the surrounding atmosphere and through the low-efficiency non-woven fabric affecting air quality, Inner Mongolia filter, medium-efficiency chemical fibre non- Company continued to carry out glue cotton material filter, and the new environmental improvement work and alkali spray tower to further prevent configured exhaust gas treatment facilities pollution to the surrounding atmosphere. in each project. The related production The process of “ condensate collection+ plants have different types of exhaust gas activated carbon adsorption ” adopted in the activated carbon adsorption regeneration organic exhaust gas treatment project can devices installed, which can recycle the recover up to 90% of the volatile organic volatile organic solvent adsorbed in the matter, and the recycled butyl acetate, activated carbon, and at the same time acetone and ethyl acetate can be applied reduce the loss caused by volatilisation. In for production. While treating volatile addition, Inner Mongolia Company has two organic exhaust gas, the economic benefits secondary alkali spray towers to enhance generated from the project are expected to the efficiency of dust treatment. The be RMB1 million per year. current dust treatment efficiency is as high 66 Environmental, Social and Governance Report 2020 The United Laboratories International Holdings Limited
