Molecule Works Inc.
Manufacturing & Processing
We are developing a low-cost (less than $100/ton) solid sorbent DAC system based on our proprietary reactor/contactor configuration. This design yields very high productivity by delivering low pressure drop, very high heat and mass transfer rates and high sorbent loading. Heat is provided through ls closed loop low temp hot water system so that no steam is needed. After initial charge, no water is consumed. Regeneration is achieved in 20 to 30 minutes.
