Hydrocracking Resid Process by Chevron Lummus Global

Application: Desulfurization, demetalization, CCR reduction and hydrocracking of atmospheric and vacuum resids using the LC-FINING Process.

Products: Full range of high-quality distillates. Residual products can be used as fuel oil, synthetic crude or feedstock for a resid FCC, coker, visbreaker or solvent deasphalter.

Description: Fresh hydrocarbon liquid feed is mixed with hydrogen and reacted within an expanded catalyst bed (1) maintained in turbulence by liquid upflow to achieve efficient isothermal operation. Product quality is maintained constant and at a high level by intermittent catalyst addition and withdrawal. Reactor products flow to a high-pressure separator (2), low-pressure separator (3) and product fractionator (4). Recycle hydrogen is separated (5) and purified (6).

Process features include onstream catalyst addition and withdrawal. Recovering and purifying the recycled H2 at low pressure rather than at high pressure can reduce capital cost and allows design at lower gas rates.
