ABSTRACT

In this research, we evaluated the possibility of using hollow fibre membranes combined with a VOC recovery system to recover high-capacity of VOCs in crude oil loading conditions. We initially investigated the performance of a basic membrane module under various conditions, and then developed and tested a large-scale membrane system. The ranges of conditions were determined based on practical and operational environments in terminals and tankers. The results of the basic membrane module experiment indicated that the recovery ratio of a multi-hydrocarbon mixture gas, in contrast to that of single hydrocarbon gases, increases proportionally with an increase in flow rate up to a point and then decreases in a curvilinear manner. Our findings demonstrate the strong dependence of VOC recovery ratio on the pressure and flow rate, while the influence of temperature is less significant. A large-scale membrane test was then conducted based on the optimised conditions of the basic membrane module, and the total recovery ratio between flow rates of 500 (N m3)/h and 1000 (N m3)/h were compared. This study demonstrates the possibility of utilising membranes for large-scale VOC separation and the necessity for further research to minimise recovery losses due to membrane module enlargement and moisture intrusion.

评估利用中空纤维膜回收油轮产生的 VOC 的可能性

摘要

在这项研究中,我们评估了使用中空纤维膜结合 VOC 回收系统在原油装载条件下回收高容量 VOC 的可能性。我们首先研究了基本膜组件在各种条件下的性能,然后开发并测试了大规模膜系统。条件范围是根据码头和油轮的实际和操作环境确定的。基础膜组件实验结果表明,与单一烃类气体相比,多烃类混合气体的回收率随着流速的增加成比例增加,直到某一点,然后以曲线方式降低。我们的研究结果表明 VOC 回收率对压力和流速的强烈依赖性,而温度的影响较小。然后基于基础膜组件的优化条件,以500(N m3 )/h 和 1000 (N m 3 )/h 进行了比较。这项研究证明了利用膜进行大规模 VOC 分离的可能性,以及进一步研究以最大限度地减少由于膜组件扩大和水分侵入造成的回收损失的必要性。
