Hydrotreatment Operations Starting-Up TRIZ Cases
- Four-Stage Heat Exchange Assembly for Diesel Wax Oil Hydrogenation
A four-heat-exchanger layout recovers heat across reacting streams and stripping tower bottoms to cut furnace load, space, and sealing burden.
- Laminar-Flow Solvent Extraction for Hydrocarbon Purification
A laminar-flow reactor combines heated hydrocarbons with solvent before cooling and separation to reduce contaminants.
- Heavy Aromatic Solvents for Catalyst Soft Coke Removal
High solubility parameter aromatic bottoms dissolve soft coke from catalysts, reducing pressure drops and maintaining activity during hydrocracking.
