Abstract
The disclosure is directed to a process and apparatus for capturing carbon by microbial fermentation. The disclosure relates to capturing off or waste gas stream(s) comprising CO and CO2 produced from a cupola furnace located in a foundry. The cupola furnaces are cost-effective melting solution, but they can generate significant air emissions. The off or waste gas stream(s) from the cupola furnace is passed to gas fermentation process and converted into one or more products by microbial fermentation.
Claims14
A process of capturing carbon by microbial fermentation, the process comprising:
- i. receiving off or waste gas stream(s) comprising CO and CO2 from a cupola furnace located in a foundry;
- ii. passing the off or waste gas stream(s) to at least one gas fermentation unit containing a culture of one or more microorganisms;
- and
- iii. fermenting the culture in the gas fermentation unit to produce a fermentation broth comprising one or more first product.
An apparatus for capturing carbon by microbial fermentation, the apparatus comprising:
- i. a cupola furnace in fluid communication with a first conduit and the first conduit is in fluid communication with a gas fermentation unit;
- ii. the gas fermentation unit in fluid communication with a second conduit, said second conduit in fluid communication with a separation unit.
