Abstract:
In some embodiments provided herein are processes for controlling carbon dioxide output levels coming from an oxidative dehydrogenation (ODH) process. Carbon dioxide output from an ODH process includes that produced in the ODH reaction and carry over when carbon dioxide is used as an inert diluent. Under certain circumstances carbon dioxide can also be consumed in the ODH process by acting as an oxidizing agent. By varying the amount of steam introduced into the ODH process an operator may alter the degree to which carbon dioxide acts as an oxidizing agent. This in turn allows a level of control in the degree to which carbon dioxide is consumed in the process, effecting overall carbon dioxide output. Minimizing the carbon dioxide output provides an opportunity to limit or eliminate the requirement for release of carbon dioxide into the atmosphere.

Claim (Index 1):
A method for controlling the carbon dioxide output from an oxidative dehydrogenation process comprising the steps of:\n i) introducing a gas mixture comprising a lower alkane and oxygen, and optionally one or more of steam and inert diluent, into at least one ODH reactor containing the same or different ODH catalysts, provided that if more than one ODH reactor is present then at least one of the ODH catalysts is capable of utilizing carbon dioxide as an oxidizing agent, under conditions to produce a product stream from at least one ODH reactor comprising corresponding alkene, and optionally one or more of unreacted lower alkane, unreacted oxygen, carbon dioxide, carbon monoxide, inert diluent, and acetic acid; ii) measuring carbon dioxide levels in one or more said product streams; and iii) either:\n a. introducing steam, or increasing amount of steam introduced, into the at least one ODH reactor in an amount sufficient to decrease the carbon dioxide output levels when the measured carbon dioxide level is above a predetermined target carbon dioxide level; \n b. decreasing the flow rate of steam introduced into the at least one ODH reactor to increase the carbon dioxide output levels when steam was introduced in step i) and the measured carbon dioxide level is below the predetermined target carbon dioxide level; \n c. increasing the volumetric ratio of oxygen to ethane in the gas mixture introduced into the at least one ODH reactors to a degree sufficient to decrease the carbon dioxide levels when the measured carbon dioxide level is above a predetermined target carbon dioxide level; or \n d. decreasing the volumetric ratio of oxygen to ethane in the gas mixture introduced into the at least one ODH reactor to a degree sufficient to increase the carbon dioxide level when the measured carbon dioxide level is below a predetermined target carbon dioxide level.
