  • Patent number: 4400265
    Abstract: A high pour point, high sulfur content gas oil is processed in a combination process wherein the gas oil is first catalytically dewaxed and then hydrodesulfurized in a cascade system which enables the two operations to be integrated through a common hydrogen system and whereby substantial quantities of thermal energy are recovered for reuse resulting in significant energy conservation.
    Type: Grant

  • Patent number: 4394249
    Abstract: A hydrocarbon feedstock is desulfurized in a conventional hydrodesulfurization process unit (HDS), and then conducted into a catalytic dewaxing process unit (DDW). The cascading relationship of the HDS/DDW units enables the operator of the plant to recover a substantial portion of thermal energy from a number of process streams and decreases the size of the compressor required in the plant.
