STACKED MEMBRANES AND THEIR USE IN GAS SEPARATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17551519 titled 'STACKED MEMBRANES AND THEIR USE IN GAS SEPARATION
Simplified Explanation
The patent application describes a membrane system consisting of two membranes that have different permeation rates and selectivities for a gas mixture. The first membrane has a higher permeation rate for a specific gas and a lower selectivity for the gas mixture compared to the second membrane. On the other hand, the second membrane has a lower permeation rate for the specific gas and a higher selectivity for the gas mixture.
- The first membrane has a higher permeation rate for a specific gas.
- The second membrane has a lower permeation rate for the specific gas.
- The first membrane has a lower selectivity for the gas mixture.
- The second membrane has a higher selectivity for the gas mixture.
Potential Applications:
- Gas separation processes
- Purification of specific gases from mixtures
- Industrial gas processing
- Environmental applications such as air pollution control
Problems Solved:
- Improved gas separation efficiency
- Enhanced selectivity for specific gases
- Increased productivity in gas separation processes
Benefits:
- Higher permeation rate for specific gases
- Improved selectivity for gas mixtures
- Increased efficiency and productivity in gas separation processes
- Potential cost savings in industrial gas processing and environmental applications.
Original Abstract Submitted
A membrane system includes a first membrane and a second membrane. At a given temperature and pressure: the first membrane has a permeation rate for a first gas and a selectivity for a gas mixture comprising the first gas a second gas different from the first gas; the second membrane has a permeation rate for the first gas and a selectivity for the gas mixture; the permeation rate of the first membrane is greater than the permeation rate of the second membrane; and the selectivity of the second membrane is greater than the selectivity of the first membrane.
