(129f) Electrochemical Oxidative Dehydrogenation (e-ODH) As a Process Intensification Platform in Shale Gas Upgrading
Within this context, Ohio University (OHIO), with funding from the U.S. Department of Energyâs National Energy Technology Laboratory (NETL) Project DE-FE0031709, is developing a modular electrogenerative oxidative dehydrogenation (e-ODH) process, which directly converts NGLs at the well head into fuels, electrical power, and pipeline-quality natural gas. In this process, ethane (and possibly other NGLs) contained in the well head gas are selectively converted into alkenes and byproduct electrical power using a solid oxide fuel cell (SOFC) module. This module could possibly be coupled with an oligomerizaton reactor for additional alkene upgrading. Advantages offered by this e-ODH process include the following: 1) Modular operation with lower capital and operating costs; 2) Selective conversion of NGLs contained in well head gas; 3) Production of gasoline range hydrocarbons, pipeline-quality natural gas, and electrical power as products; and 4) Utilization of existing SOFC and oligomerization reactor technology minimizing commercial adoption and market entry risk.
OHIO has been using both process models and experimental analyses to develop the e-ODH process via Aspen Plus simulations and high temperature catalyst development, respectively. This presentation will discuss results from both initiatives during the meeting.
