Modular ammonia recovery and catalytic abatement system
A configured stripping, absorption and catalytic-deodorization system for recovering ammonia from industrial wastewater or exhaust gas as concentrated gas or aqueous ammonia, or oxidatively abating it when recovery is not required.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Addresses ammonia-bearing wastewater and exhaust streams where discharge limits, recovery for reuse, limited installation space, and variable feed concentrations must be managed together.
Application contexts
- Chemical-process wastewater treatment
- Industrial exhaust treatment
- Ammonia recovery for process reuse
- Ammonia-handling support around hydrogen-carrier processes
Technical principle
The system combines a stripping tower with either an absorption tower to recover aqueous ammonia, a condenser to obtain concentrated ammonia gas, or a catalytic deodorization unit that oxidatively decomposes ammonia for abatement.
Typical use cases
- Recovery of ammonia as aqueous ammonia from industrial wastewater
- Recovery of concentrated ammonia gas for reuse
- Catalytic abatement of ammonia recovered from a stripping tower
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: ammonia concentration and flow rate · co-contaminants in wastewater or exhaust · required recovered-ammonia form and purity · available installation footprint · target discharge and emissions limits
