A Vinyl Acetate Plant Odor Treatment Method Research And Verification

Chongqing Hua Wei Industrial Co., Ltd. The new plant chemical means include quaternary Mao tetraol means, means sodium, sodium acetate production plant, tar recovery acetic acid plant, mixed acid recovery, recovery and vinyl acetate recovery, processing belonging to four Chuan Weini Lun plant and Yangzi waste utilization devices. A variety of different devices will have a certain amount of malodorous gases during industrial production, cause unpleasant and damaging the living environment of all gas species to stimulate the olfactory organ in the definition of national standards in the stench GB14554-93. Due to the nature of malodorous gases, in order to avoid the smell of exhaust gas produced by different plant chemical plant running equipment corrosion and the adverse effects of the plant employees, the production environment, the surrounding atmospHere caused by right, should be controlled during the operation of equipment odorous gases emissions concentration. Chemical gas absorption zone to deal with the stench of processing, the malodorous gas standards and then be discharged, in order to reduce the negative impact on the human body odor gas and the environment.According to the State promulgated the "stench emission standards" to determine the plant malodorous gases control standards; while selecting the triangle odor bag method method of detecting odorous gases in accordance with national standards. According to malodorous emissions standard way of deodorizing filter.Making deodorant equipment design before construction after a lot of preliminary research, collect relevant information deodorant. Design need to determine the type of malodorous gases, the discharge position, emissions, emission concentration, the frequency of emission, and identify odorous gases centralized and decentralized collection collects two collection methods, choice of base absorbent deodorizing washed according to the above information, bio-bed equipment deodorant, activated carbon fiber adsorption of these three malodorous gas treatment, bio-bed unit designed to process-based bio-deodorization deodorizing system deodorizing process. Also need to plant the chemical plant layout, plan view of the plant, plant relief map, the scope of the plant where the climate change information, provide reference materials for the construction of the deodorizing system design.After determining the design after construction, site construction, equipment installation, commissioning and trial run to determine the malodorous gases through the odor treatment system is up to the national emission standards for labeling requirements of post-treatment, the treated gas to meet emission standards it can be formally put into production. During the test run, he found the bio-bed devices attached bacteria on the packing of the irregular portion mortality. After investigation, found that because of acetaldehyde gas into the bio-bed leading to bacterial death, and the successful resolution of this problem. Biological deodorizing system can be formally put into operation.This study examined the project from the beginning Odor Treatment project, after preliminary investigation to gather a wealth of information, and in accordance with section and a gas processing section gas collection gathered information design deodorizing system, and to determine the process, on-site construction, equipment installation, equipment testing, commissioning and then put into the process.
