Hydrocarbon Oils Refining TRIZ Cases

A multi-level predictive control scheme replaces manual reactor tuning to keep target parameters in range and recover quickly from fluctuations.

Chemical additives dissolve mercury, arsenic, and selenium in hydrocarbons for aqueous extraction under milder conditions, reducing guard bed replacement.

Liquid-liquid extraction removes contaminants from used high-performance lubricant, preserving hydrocarbons for base-stock blending.

This case uses host-guest binding and phase separation to achieve over 99% cycloalkane purity under ambient conditions.

Phosphonium compounds form water-soluble complexes with trace heavy metals in crude oil, eliminating clogged absorbent beds and reducing reagent costs.

Segmenting polymer inhibitors into distinct temperature ranges addresses high wax content bottlenecks, reducing dosage costs while maintaining flow reliability.

Scrubbing ionic liquid phase transfers entrained droplets from immiscible hydrocarbon streams for direct recovery.

Hyper-cross-linked polymeric beads sequester aromatic compounds from engine lubricants to prevent sludge formation.

Thiol additives transform mercury into separable compounds, resolving the trade-off between removal completeness and mixing energy requirements.

Ion-exchange resins adsorb free fatty acids from crude oil, avoiding soap formation and reducing equipment costs compared to steam distillation.

A dedicated decomposition reactor converts organic chlorides to hydrogen chloride, enabling lower temperature isomerization conditions.

Lamellar double hydroxide adsorbents remove silicon contaminants to prevent catalyst poisoning and extend campaign times.

An ultrasonic transducer system generates high-frequency vibrations to separate entrained gases from hydrocarbon liquids.

Phosphate-free amine-based inhibitors prevent naphthenic acid corrosion at high temperatures without catalyst poisoning.

V-shaped baffles improve gas-solid contacting in fluidized beds, eliminating octane loss and hydrogen consumption from conventional hydrodesulfurization.

Oil-soluble hemiformal compounds remove hydrogen sulfide and mercaptans, reducing corrosion in oil and gas processing.
