  • CRYOGENIC PROCESS FOR CRUDE HELIUM RECOVERY FROM NATURAL GAS
    Publication number: 20230391621
    Abstract: The present invention relates to a cryogenic process to produce crude helium from pretreated natural gas. The pretreated natural gas is processed in two flash stages using the helium free process stream as a stripping agent, and a distillation column with the identified operating conditions and process scheme to ensure 100% helium recovery with reduced capital and operating cost for producing the crude helium. The integration of the cryogenic process with the already known purification system to produce pure helium is demonstrated to ensure high helium recovery in a hybrid process.

  • Process for the removal of sulfones from oxidized hydrocarbon fuels
    Patent number: 8562821
    Abstract: Described herein is a process for the removal of sulfones by mesoporous silica adsorbents having narrow pore size distribution which could be controlled to specification for the selective removal of sulfones from oxidized hydrocarbon fuels wherein the sulfones were present due to oxidative conversion of organo-sulfur compounds by a suitable oxidizing solution. The mesoporous adsorbents showed typically 2-18 times higher equilibrium loading capacity for sulfones in comparison to the commercially available adsorbents.
    Type: Grant
