  • LNG pretreatment
    Patent number: 9051228
    Abstract: A natural gas feedstream containing contaminants such as carbon dioxide is purified by passing the contaminated natural gas stream through a membrane to remove the bulk of the contaminant, passing the purified natural gas stream to a TSA unit to remove additional contaminant from the natural gas stream to a desired specification, and regenerating the TSA adsorbent by heating the adsorbent with a heated contaminant-containing permeate stream from the membrane.

  • Regenerative adsorption process for removal of silicon-containing contaminants from process gas using a neutral adsorbent media
    Patent number: 9039807
    Abstract: A natural gas-containing stream such as biogas from landfills and sewage treatment plants is freed of siloxane contaminants by passing the biogas through a bed containing an adsorbent having a neutral surface, which adsorbs the siloxanes. When the bed of neutral adsorbent is filled to capacity, the adsorbent bed is heated to remove the siloxanes and regenerate the bed. The neutral adsorbent reduces disadvantageous reactions between the adsorbent and siloxane and other impurities in the natural gas-containing stream.
