Abstract
The present invention advantageously provides a conventional dessicant bed with means for removing residual mercury, H.sub.2 S and CO.sub.2 from a gas, such as a natural gas stream, by replacing an inert protective layer of pellets with an active compound comprising at least one of copper hydroxide, copper oxide and copper sulfide. The active compound provides the dessicant bed with the additional advantage of removing H.sub.2 S and CO.sub.2 as well as mercury from the gaseous fraction without incurring the pressure loss inherent in utilizing a separate downstream adsorbent bed for removing Hg.
