Application and improvement of deodorization process in the city gas

In order to ensure timely detection of gas leakage, civil gas must be odorized when it is supplied. Civil gas deodorization technology is widely used in southwest China. Taking the deodorization technology of Dazhou City and Nanchong City as an example, the selection of equipment, operation status and management mode were discussed in this paper. The comparative analysis of the dosage of deodorizer and monitoring concentration data has been done. It is found that there are some factors to be improved such as excessive dosage in the dosage of deodorizer, unstable concentration and great environmental impact. In order to reduce the cost and increase efficiency, ensure the safe use of gas, it is proposed to change the manual charging process in fixed frequency to automatical charging timely in order to control the back-end concentration effectively, reduce the atmospheric environment impact, and decrease the waste of deodorant.
