Abstract
The invention relates to a process for removing heavy hydrocarbons and hydrogen sulfide from natural gas. The combination of a silica-gel and an activated carbon adsorber allow for a significant reduction in the overall bed volume required for removal of hydrocarbons.
Claims16
A process for pretreatment of a natural gas stream containing methane, higher hydrocarbons, hydrogen sulfide and carbon dioxide wherein said process comprises passing said natural gas stream through at least one layer of a silica gel adsorbent and then through at least one layer of an activated carbon adsorbent.
A system for pretreatment of natural gas stream containing methane, higher hydrocarbons, hydrogen sulfide and carbon dioxide comprising an adsorbent bed comprising at least one layer of a silica gel adsorbent and at least one layer of an activated carbon adsorbent.
