摘要：
一种从含有水和酸性物质的天然气进料物流中除去污染物的方法，该方法包括以下步骤：在第一容器(12)中将天然气进料物流冷却至水合物形成的第一操作温度，和从第一容器(12)中移出脱水的气体物流(34)；以及在第二容器(14)中将脱水的气体冷却至固体酸性物质形成或该酸性物质溶于液体中的第二操作温度，和从第二容器(14)中移出脱水、脱硫的气体物流(62)。
摘要（英）：

A process for removing contaminants from a natural gas feed stream including water and sour species, which process comprises the steps of cooling the natural gas feed stream in a first vessel (12) to a first operating temperature at which hydrates are formed and removing from the first vessel (12) a stream of dehydrated gas (34); and cooling the dehydrated gas in a second vessel (14) to a second operating temperature at which solids of the sour species are formed or at which the sour species dissolve in a liquid and removing from the second vessel (14) a stream of dehydrated sweetened gas (62).
