Modeling and Investigation of an Industrial Dehydration and Hydrocarbon-Removal Process by Temperature Swing Adsorption

In this study, a water- and heavy hydrocarbon-removal process of natural gas refinery currently in operation using the temperature swing adsorption method is modeled investigated. The aim to decrease hydrocarbon dew point −10 °C diminish water content about 0.1 ppm. This unit consists four beds with two layers which are state, while others kept regeneration state. composition bed specification obtained from available data refinery. Ergun equation considered for pressure drop calculation. results show that developed model can predict outputs good accuracy. Sensitivity analysis operating condition parameters such as temperature, pressure, flowrate carried out. Analysis proved reduction 268 210 improve recovery components. addition, flow rate be reduced 0.4 kmole·s−1 an optimum value. Moreover, 303 310 range feed temperature. Due presence air cooler upstream process, according ambient decreased obtain better results.
