Hydrocarbon Oil Cracking TRIZ Cases

An integrated process combines hydrodesulfurization and hydrocracking zones to produce low sulfur diesel.

A single-stage catalyst system converts aromatic hydrocarbons into jet and diesel fuels, eliminating multiple reactor stages.

A selective series-flow hydroprocessing system separates feedstock into aromatic-rich and lean fractions for targeted treatment.

Optimized hydrocarbon base oil composition resolves the trade-off between low-temperature fluidity and sealing pressure to prevent leakage.

Aromatic solvent injection prevents heavy polynuclear aromatic precipitation and equipment fouling in hydrocracking units.

A hydrotreating unit removes sulfur from a diesel stream before the hydrocracking reactor converts heavy hydrocarbons.

Polymeric compositions lower crude oil pour points using ethylene-vinyl ester copolymers, preventing solidification at low temperatures.

High-saturate base stocks with controlled aromatic absorptivity improve oxidation stability and low temperature properties while reducing additive content.

Segmented by-passable hydrocracking reactors increase distillate yields while preventing sediment accumulation that degrades fuel quality.

Separates polycyclic aromatic hydrocarbons from the heavy oil recycle stream via vacuum distillation, preventing catalyst deactivation and equipment fouling.

Splitting compressed hydrogen feeds separate hydrocracking and hydrotreating units, reducing capital costs by eliminating redundant supply systems.

A thermal hydrodealkylation unit removes alkyl groups from polynuclear aromatic compounds before hydrocracking.

Segmented ring-opening and hydrocracking stages boost aromatics yields while lowering hydrogen consumption.
