Abstract :
In this study, a novel method for the optimized odorization of natural gas using a bypass system with a cylindrical bubble column was employed. The natural odorant used in this research was ethyl mercaptan. The performance characteristics of a butterfly valve, which could be applicable for use in the gas-phase bypass odorization control system, were investigated. Additionally, a mathematical model was developed to predict the process. The results indicate that the high mass transfer rate in this method leads to a high operational capacity of the system. At valve opening angles below 50 degrees, the butterfly control valve allows only a negligible amount of gas to pass under specified pressure differentials.
