A reactor system is provided for improved fermentation of a gaseous substrate through the introduction of a secondary loop to a forced-circulation loop reactor. The reactor comprises a primary loop through which fermentation broth comprising a gaseous substrate is circulated through a riser segment and a downcomer section by a loop pump. Downstream of the loop pump a portion of fermentation broth is withdrawn from the downcomer section and is directed to the top of the reactor via a secondary loop. Further provided is a method for improving the mass transfer of a gaseous substrate to a fermentation broth in a fermentation vessel comprising a secondary loop. Further provided is a method for reducing foam in the headspace of a fermentation vessel comprising a secondary loop.
A reactor system for fermentation of a gaseous substrate, the system comprising:
A method for improving mass transfer of a gaseous substrate to a fermentation broth in a fermentation vessel comprising a riser section wherein a liquid fermentation broth and the gaseous substrate are flowed concurrently upwards and a downcomer section wherein the liquid fermentation broth and the gaseous substrate are flowed concurrently downward, the method comprising:
A method for reducing foam in the headspace of a fermentation vessel comprising a riser section wherein the liquid fermentation broth and the gaseous substrate are flowed concurrently upward and a downcomer section wherein the liquid fermentation broth and the gaseous substrate are flowed concurrently downward, the method comprising:
