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 18):
A system for chemical production from ethane, the system comprising:\n a catalytic reactor configured for reacting ethane with carbon dioxide at a temperature of about 450\u00b0 C. or greater to form a reaction product stream including at least ethylene and carbon dioxide; an ethane line configured for delivery of ethane into the catalytic reactor; a carbon dioxide line configured for delivery of carbon dioxide into the catalytic reactor; a primary heat exchanger configured to receive the reaction product stream from the catalytic reactor and withdraw heat therefrom; a gas-liquid separation unit configured for removal of water and optionally other condensates from the reaction product stream; a compressor configured for compressing the reaction product stream to a pressure of at least 20 bars; a carbon dioxide separation unit configured for receiving the reaction product stream after at least one stage of compression and for separating at least a portion of the carbon dioxide from the reaction product stream to provide an upgraded stream comprising ethylene; and a line configured for delivering at least a portion of the carbon dioxide separated from the reaction product stream in the carbon dioxide separation unit to the reactor while being heated with at least a portion of the heat withdrawn from the reaction product stream in the primary heat exchanger.
