Effects of Piperazine on Removal of Hydrogen Sulfide from Liquefied Petroleum Gas (LPG) using Aqueous Methyl Diethanol Amine (MDEA)Author(s): Matib M and Zoubida L*
The main aim of this study is to investigate the effect of the use of piperazine as an additive on the MDEA solutions which is already used to sweeten LPG from H2S and CO2. ASPEN HYSYS is used to simulate this case study. In this article many design criteria (MDEA concentration, piperazine concentration, amine solution flow rate etc.) are studied. The composition and operating conditions of pressure and temperature of LPG to be treated is taken from literature and slightly modified, in such situation the composition of our LPG Feed can be considered as theoretical, the flow and the other operating parameters of AGRU (Acid Gas Removal Unit) are also optimized.
