What This Patent Covers

This patent protects a method for recovering flammable gas from steam-containing mixtures using a specific polymer-based adsorbent, primarily composed of diene rubber and silicone rubber particles under 1.0mm. The claims cover the selective adsorption and depressurization recovery process, establishing a robust and stable right that has withstood rigorous examination.

Competitive White Space

This patent primarily covers specific polymer-based adsorbents and a pressure-swing adsorption process for flammable gas recovery. White space exists in exploring alternative adsorbent materials (e.g., MOFs, zeolites), integrating with other separation techniques (e.g., cryogenic, membrane) for multi-component gas streams, or developing advanced process controls for dynamic gas compositions.

ROI Calculation Logic

Assuming an annual loss of 1,000 tons of flammable gas (e.g., methane) from associated gas emissions. Recovering 50% of this for reuse as fuel, with a methane fuel unit price of ~$670/ton (AI est.), results in an annual recovered value of 1,000 tons × 50% × ~$670/ton = ~$335K (AI est.). This directly translates to a reduction in fuel purchase costs.

Speed to Market
4× faster than in-house development
This technology benefits from clearly defined adsorbent material composition and recovery processes, with established foundational algorithms. The technical requirements, such as particle size and polymer composition specified in the claims, can be met relatively easily by adapting existing adsorbent manufacturing techniques. This significantly shortens the time to market compared to in-house development, enabling faster commercialization and revenue generation.

Integration Roadmap — Estimated 18-Month Deployment
Phase 1: Technical Evaluation & System Design
Duration: 4 months
Analyze existing facilities and exhaust gas composition to evaluate implementation feasibility and design the optimal system configuration. This includes selecting specific adsorbents and designing the recovery process.
Phase 2: Pilot Validation & Equipment Development
Duration: 8 months
Based on the design, construct a small-scale pilot plant for on-site demonstration experiments. Data acquisition and performance evaluation will verify recovery efficiency and durability, optimizing the system for full-scale deployment.
Phase 3: Full-Scale Deployment & Operation Optimization
Duration: 6 months
Based on pilot results, implement full-scale recovery equipment and integrate it into existing systems. Develop operational manuals and provide technical transfer to on-site personnel to ensure stable operation and continuous performance improvement.
Technical Feasibility
This technology's adsorbent, primarily composed of fine particles less than 1.0mm in diameter, can be easily filled and integrated into general-purpose gas processing equipment like existing adsorption towers or packed-bed reactors. This allows licensees to minimize large-scale equipment modifications or new investments, potentially integrating this technology as an add-on to existing gas treatment lines. The clear material composition and process conditions described in the patent suggest low technical implementation hurdles.
Success Scenario
Upon adopting this technology, licensees could efficiently recover high-purity flammable gas from steam-containing exhaust streams that were previously vented or incinerated. This could lead to annual fuel cost reductions in the hundreds of thousands of dollars and establish new revenue streams from selling recovered gas. Furthermore, it is estimated to contribute to CO2 emission reductions, enhancing corporate ESG ratings and securing a competitive advantage in future carbon taxation or emissions trading schemes.
