Ammonia Preparation/Separation TRIZ Cases
- Ammonia Synthesis Heat Recovery with Staged Steam Generation
An ammonia plant adds downstream medium-pressure steam generation to recover heat, improve temperature control, and ease revamping.
- Ammonia Synthesis Flow Control for Compressor Surge Prevention
This case uses segmented catalyst-bed flow control and gas heat exchange to stabilize compressors and reduce cooling energy.
- Ammonia Synthesis Cooling Integration for Renewable Flow Stability
This case uses staged cooling and nitrogen heat exchange to manage renewable flow swings, stabilize compressors, and improve ammonia yield.
- Ammonia Synthesis Flow Control for Variable Renewable Operation
Recirculation and adjustable separation help prevent compressor surge and catalyst-bed temperature deviations as renewable power varies.
- Ammonia Synthesis Recirculation for Variable Flow and Compressor Stability
Dynamic feed and sweep gas recirculation maintains catalyst temperature uniformity and limits compressor surge as renewable input changes.
- Single Start-Up Oven for High and Low Pressure Ammonia Reactors
One start-up oven serves multiple reactors through valve switching, reducing equipment complexity while maintaining reliable reaction initiation.
- Ammonia Scrubber Wastewater Reduction via Dynamic Solvent Control
Dynamic solvent circulation adjusts to renewable power fluctuations, minimizing wastewater generation while maintaining ammonia purity.
- Inert Gas Recovery from Ammonia Synthesis Loop
Gas ejector transports separated inert gases to fuel stations using plant motive streams.
- Ammonia Distillation System with Corrosion Inhibitor
A distillation system adds corrosion inhibitors to liquid anhydrous ammonia in a collection tank.
- Dual Pressure Ammonia Synthesis with Effluent Recycle
A dual pressure ammonia synthesis process recycles gaseous effluent from the first step to boost production capacity.
- Ammonia Synthesis Monolithic Heat Exchanger
Monolithic heat exchangers condense and subcool ammonia from reactor wet gas, reducing fossil energy consumption.
- Ammonia Recovery from Wastewater via Mass-Transfer Kinetics
Optimizing base concentration, acid dosage, and air diffuser orifice diameter increases ammonia removal rates while eliminating packing material scaling.
