Effect of Pressure on the Separation of Ethylene from Ethylene/Ethane Gas Mixture Using Hollow Fiber Membrane

摘要

The aim of this work is to study the effects of pressure, gas flow rates, liquid flow rates and silver nitrate concentration on the separation of ethylene/ethane gas using hollow fiber membrane contactor. A mathematical model is developed; the model considers the gas solubility as a function of pressure, temperature and silver nitrate concentration. The model is validated by the accomplished experimental data. The results of model predictions and the experimental data are in excellent agreement. The obtained results indicated that ethylene/ethane separation increases with increasing the inlet gas pressure to certain extent, silver nitrate concentration and liquid flow rates.
