  • Process for crude petroleum oil processing in the crude distillation unit (CDU)
    Patent number: 11859139
    Abstract: Method for crude petroleum oil processing in Crude Distillation Unit is provided to eliminate the stripping steam in an Atmospheric Distillation Column (VDC) of CDU for a significant reduction in the CDU's operating cost and alleviating the corrosion in the overhead section of ADC. The present invention relates to a method of separating the components of crude petroleum oil. The proposed method utilizes the innovative application of process hydrocarbon vapour consisting of a lighter fraction of crude and natural gas. The conceptualized new schemes for downstream processing the Light and Heavy gas oil (LGO and HGO) distillates to meet their boiling specifications are also disclosed.

  • 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.
