Mobile Biogas Purification via Clathrate Formation

The patent utilizes phase transition of water from liquid to solid (freezing) to enable purification. By cooling the biogas mixture to sub-zero temperatures, water condenses and freezes, separating it from the gas phase. This phase change allows effective removal of water and other contaminants without requiring large volumes of water for scrubbing, thus resolving the contradiction between purification effectiveness and water consumption.

The patent changes the temperature parameter from ambient to sub-zero conditions to alter the physical state of water and enable purification. This parameter change allows the system to operate with minimal water consumption while maintaining high purification effectiveness, as the temperature-driven phase transition naturally separates contaminants from the biogas stream.

The patent replaces complex mechanical high-pressure scrubbing systems with a simpler thermal-based purification system. Instead of using high-pressure water injection and complex scrubbing machinery, the system uses temperature control to induce phase transition of water, achieving purification through thermal fields rather than mechanical fields. This substitution reduces device complexity while maintaining or improving purification efficiency.

By leveraging the phase transition of water from liquid to solid at sub-zero temperatures, the patent achieves efficient purification without requiring high-pressure mechanical systems. The phase change process naturally separates contaminants from the gas stream, eliminating the need for complex high-pressure scrubbing equipment and reducing overall system complexity.

The patent designs a dynamic, flexible purification system that can be adapted to mobile applications. The system uses a portable pressure vessel that can be deployed in various locations, and the operational parameters (temperature, pressure) can be adjusted based on local conditions. This dynamic design allows the same purification technology to function effectively in both stationary and mobile contexts, resolving the contradiction between purification effectiveness and adaptability.

The phase transition-based purification mechanism inherently provides adaptability to mobile applications. The system uses a portable pressure vessel that can be deployed in various locations, and the temperature-driven phase change process works effectively regardless of location. This eliminates the need for large stationary infrastructure, enabling the system to be adapted to mobile and remote applications while maintaining purification effectiveness.

The patent employs phase transition of water at sub-zero temperatures to achieve purification with minimal water consumption. By freezing water in the biogas mixture, the system separates contaminants from the gas stream without requiring large volumes of water for scrubbing. This makes the system operationally feasible in areas with limited water resources, as it uses a fraction of the water required by conventional methods while maintaining purification capability.

The patent changes the temperature parameter to sub-zero conditions to enable purification in water-scarce environments. This parameter change allows the system to operate effectively with minimal water input, as the temperature-driven phase transition naturally separates contaminants without requiring large volumes of water for washing or scrubbing. This resolves the contradiction between purification capability and operational feasibility in water-limited areas.
