吸附罐空隙率对天然气脱CO2性能的影响
Effect of adsorption column porosity on removing CO2 from natural gas
摘要
Abstract
The porosity of adsorption column was changed due to the swing motion of the boat for the offshore natural gas production. To study the effect of adsorption column porosity on adsorption purification, an adsorption experimental apparatus was built. A two-dimensional adsorption purification model was established based on the experiment data, and the validity of the model was confirmed. Result shows that the mass fraction of CH4at the exit of adsorption column rose to more than 0.99 mole fraction with the increase of adsorption column porosity at the static state. The adsorption heat in the adsorption column rose with the increase of adsorption column porosity. In the case of flowing adsorption, the pressure drop in the adsorption column decreased dramatically with the increase of adsorption column porosity. The best adsorption purification achieved when the adsorption column porosity was 0.35. Along the axis direction of the adsorption column, adsorption heat showed a downward trend, and decreased rapidly with the decrease of the adsorption column porosity. This study will help improve the production efficiency of offshore natural gas, and have a significant effect on the rapid development of natural gas.关键词
