Abstract:
The present disclosure relates to methods and systems suitable for chemical production by dehydrogenation of ethane utilizing carbon dioxide as a soft oxidant. Ethane and carbon dioxide are reacted in a catalytic reactor to produce a reaction product stream comprising at least ethylene and carbon dioxide. The carbon dioxide can be separated for recycling back into the catalytic reactor, and the ethylene can be upgraded using a variety of process units. Heat from the reaction product stream can be recycle for further uses, including reducing the amount of added heating needed in the catalytic reactor. Additional materials, such carbon monoxide, hydrogen, syngas, methanol, methane, ethane, and even heavier hydrocarbons can be provided.

Claim (Index 1):
A method for chemical production from ethane, the method comprising:\n providing ethane and carbon dioxide into a reactor at a molar ratio so that the amount of provided carbon dioxide is in excess of the stoichiometrically required amount for complete reaction with the ethane; reacting the ethane with the carbon dioxide in a reactor in the presence of a catalyst to form a reaction product stream at a temperature of about 450\u00b0 C. or greater comprising at least ethylene, water, and carbon dioxide; passing the reaction product stream through a primary heat exchanger to withdraw heat therefrom; removing water and optionally any further condensates present in the reaction product stream; compressing the reaction product stream to a pressure of at least  20  bar; separating carbon dioxide from the reaction product stream in a separation unit to provide an upgraded stream comprising ethylene; heating at least a portion of the carbon dioxide separated from the reaction product stream using the heat withdrawn from the reaction product stream to form a stream of heated carbon dioxide; recycling the stream of heated carbon dioxide back into the reactor; and further processing the upgraded stream comprising ethylene to provide at least ethylene as a produced chemical.
