Gas Treatment TRIZ Cases
- 2-Furonitrile Production via Mo/SiO2-Catalyzed Dehydration
Mo/SiO2-catalyzed dehydration converts 2-furamide to 2-furonitrile, addressing hazardous carbonyl chemistry and difficult process regeneration.
- Multi-Stage Biogas Membrane Separation for Lower Compression Energy
Multi-stage membranes and high- and low-pressure recycle loops remove CO2 and H2S while reducing compression energy.
- Compact CO2 Scrubber Canister for Uniform Cross-Flow
Parallel screens and cross-flow channels distribute gas uniformly through a compact CO2 absorbent bed while reducing breathing resistance.
- Metal-Containing MOR Zeolites for Humid Low-CO2 Air Capture
Metal-ion MOR zeolites target slow, energy-intensive capture from dilute humid air with desiccant-assisted regeneration near 100°C.
- Water-Wash Pretreatment for Natural Gas Sweetening and Contaminant Removal
A co-current water wash removes chemical and particulate contaminants before amine treatment, reducing foaming and fouling in sour-gas sweetening.
- Mixing Nozzle With Baffle Reversal for Microparticle Purification
Baffle reversal separates mixed flow and uses centrifugal force to bring contaminated-gas microparticles into contact with decontamination solution.
- Gas Recovery Microturbines for Hydrogen and Ammonia Waste
Compressed and buffered hydrogen or ammonia waste gases drive variable-speed microturbines, recovering electricity instead of releasing or burning them.
- Hydrogen Production Through Oxy-Fuel Reforming and CO2 Capture
Oxy-fuel combustion heats sequential reformers while recycling CO2-rich gases, integrating hydrogen production with carbon capture.
- Quinone Electroactive Species for Reversible Lewis Acid Gas Capture
Quinone electroactive species reversibly bind Lewis acid gases as anion adducts, supporting selective separation even in the presence of dioxygen.
- Electromagnetic Plasma Separator for Scalable Greenhouse Gas Removal
Heating air to at least 8000 K ionizes greenhouse gases, while superconducting magnets separate CO2 and CH4 for scalable removal.
- Internal-Weir Immiscible Fluid Contactor With Dual Flow Paths
An internal weir divides the chamber so immiscible fluids undergo co-current and countercurrent contact through separate flow paths.
- MnOx/FeOx Denitration Catalyst for Low-Temperature SCR
MnOx/FeOx replaces V2O5/TiO2 in SCR, targeting high NOx conversion at 100–300°C in humid, SO2-exposed conditions.
- Biogas PSA Methane Recovery With Surge-Tank Buffering
A surge tank buffers PSA pressure changes and recycled methane flow, addressing bed pressure limits that reduce biogas methane recovery.
- Recyclable Porous Barium MOF for CO₂ Capture and Conversion
A porous barium MOF uses 17–19 Å molecular-honeycomb pores to capture CO₂ and convert it to cyclic carbonates through nine cycles.
- Ceria-Alumina Supported Catalysts for Stable H2S Oxidative Cracking
Fe, Co, or Ni supported by ceria and alumina promotes H2S oxidative cracking while limiting sintering at high temperature.
