Yanlian Existing Problem Of Gas Refining Process

With the constant deepening of China’s economic reform, the domestic economy has maintained sustained and rapid growth. By macro-economic driven growth in demand for all kinds of petrochemical products, leading to the production plant processing capacity continues to increase. At the same time, some petrochemical products production enterprises are constantly on the original production device to carry on the reform and expansion, so as to seek the overall dimensions economic benefits. Domestic pay more and more attention to the amine desulfurization, methyl two ethanol amine (MDEA) desulfurization solvent with low energy consumption, good selectivity for H2S absorption and low corrosion has got a wide application. This paper describes the measures of amine liquid loss, foaming and corrosion factors, mechanism and the corresponding alcohol amine desulfurization process using Yanlian liquefied gas refining device. Introduces the heat stable salts (HSS) adverse consequences, causes and brings forward APU, amine liquid purification technology, the system uses the shallow bed ion exchange resin, can effectively remove HSS, examples prove that HSS removal to reduce the consumption of amine, corrosion protection and reduce the foam has a significant effect.This article is based on a background topics start on Shaanxi yangchang pertroleum group refining and petrochemical company in the device production run problems for the analysis of proposed corrective measures, the implementation of the production run program.
