Fractional Condensation Purification/Separation TRIZ Cases
- Hydrocarbon Synthesis System Using RWGS for CO Supply
Separating water electrolysis from RWGS secures carbon monoxide for hydrocarbon synthesis while improving catalyst stability and system efficiency.
- Methanol-Ethanol Olefin Production With Flexible Recycle Splits
A two-stage DME-to-olefin process tunes ethylene, propylene, and butene output while cutting hydrocarbon recycle volume and energy use.
- Deethanizer LPG Separation for Hydrogen Sulfide Removal
A deethanizer shifts hydrogen sulfide into the overhead stream so LPG can meet H2S specifications without amine treating.
- ODH Oxygenate Separation Using Cooling, Quench, and Caustic Recycle
Non-dilutive cooling and carbonate quenching remove oxygenates from ODH streams while caustic recycle simplifies alkene purification and cuts energy use.
- Thin-Film Electrolysis Cell With RWGS Path for CO Supply
Hydrogen from water electrolysis is reused in an integrated RWGS discharge path to raise CO supply for compact hydrocarbon production.
- C4+ Hydrocarbon Recovery by Partial Condensation of AC Vapor
Partial condensation of compressed acid-condensation vapor recovers C4+ hydrocarbons that would otherwise be lost, improving yield and recovery efficiency.
- Two-Stage Quenching Separates Hydrocarbons Before Fractionation
Separate water and hydrocarbons in a cooler quench circuit to reduce repeated fractionation, equipment volume, and deposits.
- Olefin Stream Oxygenate Removal via Methanol Washing
Methanol washing extracts oxygenates from compressed olefin streams, avoiding complex distillation and preserving methanol for synthesis.
- Mixed Refrigerant Composition for Cryogenic Hydrogen Separation
A mixed refrigerant composition comprising inert gas, methane, and hydrocarbons cools process streams to separate hydrogen from light hydrocarbons.
- Olefin Recovery Membrane Separation in Polyolefin Purge Gas
Dual membrane treatment of condensed liquid and uncondensed gas streams recovers olefin while selectively purging paraffin buildup.
- Olefin Production Oxygenate Recycling Process
Direct C4-O stream recycling to the OTO reactor simplifies purification and reduces extractive distillation costs.
- Olefin Separation Sequence Inversion for Refrigerant Reduction
Reversing the deethanizer and depropanizer order allows chilled water cooling, cutting propylene refrigerant consumption and system size.
