13 Claims

1. A method for optimizing the flow of gas to parallel fermentation processes, the method comprising:

a) separating a gas stream derived from at least one industrial source into a hydrogen rich stream and a hydrogen depleted stream using at least one hydrogen separation module;

b) passing the hydrogen rich stream and hydrogen depleted stream in parallel to a first and second fermentation process respectively said first and second fermentation processes being run in parallel;

c) fermenting at least a portion of the hydrogen rich stream in the first fermentation process using at least one reactor comprising a liquid nutrient medium containing a culture of at least one C1-fixing microorganism to produce a first fermentation product; and

d) fermenting at least a portion of the hydrogen depleted stream in the second fermentation process comprising at least one reactor comprising a liquid nutrient medium containing a culture of at least one C1-fixing microorganism to produce a second fermentation product, wherein the first fermentation product and the second fermentation product are different products.
