国内已开发掌握了多种天然气脱硫工艺,基本上满足了当前气田开发的需要。然而,就已经出现及可能出现的气源而言,拓宽天然气脱硫工艺的适应性是必要的。现需考虑的主要有四个方面:高碳硫比天然气,特高酸气含量天然气,潜硫量不大而酸气又不能灼烧排空的天然气及解决对撬装脱硫装置的适应性。讨论了拓宽天然气脱硫工艺对上述四个方面适应性的若干现实及可能的途径。

Developing Adaptability of Natural Gas Sweetening Process

Various natural gas sweetening processes were developed and grasped at home, and have met the gas field developing need on the whole at present. But, in the light of gas source already appearing and probably appearing, developing the adaptability of natural gas sweetening process is necessary. There are four respects which must be considered: the high ratio of carbon to sulfur in natural gas, extra high acid content natural gas, the natural gas with low latent sulfur content and of which the acid gas is un- able to blow down and burn, as well as settling adaptability of skid mounted sweetening unit. Many re- alistic and probable ways enlarging natural gas sweetening process to fit the above-mentioned four re- spects are discussed in this paper.
