  • COMPOUND BED DESIGN WITH ADDITIONAL REGENERATION STEPS FOR REMOVAL OF VARIOUS SULFUR SPECIES FROM LIGHTER HYDROCARBON STREAMS CONTAINING TRACE LEVELS OF OLEFINS
    Publication number: 20180016210
    Abstract: A process is provided to remove impurities including water, mercaptans, carbonyl sulfide and hydrogen sulfide from hydrocarbon streams containing from 100 to 900 ppm light olefins. In the process, a compound bed containing multiple layers of molecular sieves is used to remove the specific impurities. In situations when the regeneration gas may contain sulfur compounds, a sulfur guard bed may be used to treat the regeneration gas prior to regenerating the compound adsorbent bed.

  • METHOD FOR TREATING SPENT REGENERATION GAS
    Publication number: 20110142738
    Abstract: The invention covers a method for treating spent regeneration gas from one or more molecular sieve treaters, first in an amine solvent unit and then in a caustic unit. The amine solvent unit removes hydrogen sulfide and carbonyl sulfide and the caustic unit removes mercaptans. Optionally, there are additional treatments before the treated gas has met specifications for burning as a fuel or used for other purposes.
