Question

求翻译一段化工类的英文文献

Therefore, the gas separation process with MDEA is far more stable with no spurious plant shutdowns over longer periods. The use of different amines (primary, secondary, and tertiary) depends upon the composition of H2S and CO2 in the acid gas. Depending upon the acid gas composition the primary, secondary, and tertiary amines are used at different stages/units to cope with the problem. The interest in the use of mixed amine systems in gas treating processes also is increasing nowadays. The mixed amine system, which combines the higher equilibrium capacity of the tertiary amine with the higher reaction rate of the primary and secondary amine, may improve considerably the absorption of CO2 provide great savings in the regeneration energy requirement [8,9].
Amine scrubbing for removing H2S and CO2 from gas streams is not straightforward. Amine plant operational problems such as excessive foaming, corrosion, and capacity reduction, are often attributed to the accumulation of amine heat stable salts (HSS). Thus, HSS leads to costly maintenance problems such as corrosion, frequent filter replacement, foaming in the absorber and a reduction in the amount of amine available for gas treating.

因此，MDEA的气体分离过程更加稳定，并且在较长时间内没有伪造工厂停工。使用不同的胺（一级，二级和三级）取决于酸性气体中的h2s和co2的组成。根据酸性气体组成，在不同的阶段/单位使用伯胺，仲胺和叔胺来应付问题。在气体处理工艺中使用混合胺系统的倾向也在日益提高。混合胺体系结合了叔胺的较高的平衡容量和较高的伯胺和仲胺的反应速率，可以显着地改善二氧化碳的吸收，从而大大节省了再生能量的需求。
用于从气流中除去h2s和co2的胺洗涤并不简单直接。胺工厂的运行状况，例如过度起泡，腐蚀和容量降低，往往归因于胺热稳定盐（HSS）的积累。而HSS导致昂贵的维护问题，例如腐蚀，频繁的过滤器更换，以及吸收器中的发泡和可用于气体处理的胺的损失。
