COMPACT INLINE GAS HUMIDIFIER
Utilizing thin zeolite membrane with both high H2O molecular selectivity and permeance
1. Introduction
Dry gas flows through one side of the device while the other side is filled with water. The water molecules selectively transport from water into gas phase, driven by partial pressure difference. In addition to humidification, the gas temperature can be increased by circulating hot water.
2. Performance Attributes
-
No gas/liquid crossover: no gas loss to water, no water droplet in gas
-
The membrane bocks transport of any bacteria, virus and inorganic/organic
impurities from water into gas.
-
The zeolite/porous Nickel alloy sheet is bio-fouling resistant
-
The device made of polycarbonate glass for low-pressure and low-temperature applications
-
The device made of stainless steel for higher pressures and/or temperatures
-
Compact and easy maintenance
3. Application Example
Dry air heating and humidification (membrane area 40 cm2)
| Air flow rate |
Air humidity before humidification |
Air humidity after humidification |
Water tank temperature |
Air temperature before humidification |
Air temperature after humidification |
| 9 L/min |
22% RH |
90% RH |
45℃ |
26℃ |
39℃ |
• At constant temperature, degree of humidification increases with decreasing gas flow rate.
bio-equip.cn Molecule Works Inc. (MWI) is a US-based technology company, registered in the State of Washington, and established in 2015 to pursue commercialization of three fundamental inventions licensed from Pacific Northwest National Laboratory (PNNL): thin porous metal sheet, thin-sheet zeolite membrane, and cassette-type membrane module. Since then, MWI has successfully demonstrated scale-up of all the critical membrane preparation steps and established its proprietary pilot manufacturing capabilities for production of thin porous metal and zeolite membrane sheets. The pilot-scale manufacturing capabilities enable production of a large number of 20cm x 20cm membrane sheets for application prototype development and customer sampling.
MWI has developed several innovative manufacturing methods and processes for production of the porous metal sheet-based membrane products at low cost. MWI has also made a series of new inventions for applications of its membrane products.
