摘 要: | 针对一种吸收塔带有侧线抽出的节能流程,通过比较各参数在一定范围内的变化对系统总费用的影响程度,辨识了影响吸收稳定系统效益的关键参数,还考察了烯烃以及能源市场价格变化对参数辨识的影响。结果表明,凝缩油罐温度和补充吸收剂流量是两个关键操作参数,解吸塔压力、吸收塔侧线抽出量和抽出位置、稳定塔进料温度对系统总费用有着较大的影响,稳定塔进料位置、解吸塔热进料比例则对系统总费用的影响较弱。

DENTIFICATION AND ANALYSIS OF KEY PARAMETERS FOR ENERGY CONSERVATION PROCESS OF ABSORPTION AND STABILIZATION SYSTEM WITH INTENSIFYING ABSORPTION PROCESS |
| |
Abstract: | By comparing the effect of changing parameters in a range on overall cost of an absorption tower with a side-draw in the energy conservation process, key parameters which influence the economic benefit of the absorption-stabilization system were indentified. The effect of changes of olefin and energy prices on parameters identification was also studied. Case study showed that, regardless of how the olefin prices and energy prices changed, the condensed oil tank temperature and supplementary absorbent flow rate are two key parameters. Desorption tower pressure, feed temperature of stabilization tower, and side draw flow rate and location of absorption tower have larger effects on the total cost. While the feed location on stabilization tower and hot feed proportion of desorption tower have little effect. |
