lower energy metal chloride reaction

eShuttle EDC

Our first product with the eShuttle® platform is the production of ethylene dichloride (EDC) with sodium hydroxide and hydrogen gas. In the conventional production method, salt and water are electrochemically split through the chlor-alkali process to produce chlorine gas, sodium hydroxide and hydrogen gas.
The chlorine gas then reacts with ethylene gas in the direct chlorination process to produce ethylene dichloride.
Our technology uses the same feedstocks to produce the same products with our lower energy metal chloride reaction.

eShuttle EDC-ODC

Our eShuttle® platform is compatible with Covestro’s oxygen depolarized cathode (ODC) technology to produce sodium hydroxide that is currently expanding in the chlor-alkali industry in regions with high energy costs. The combination of eShuttle® EDC and ODC further lowers the power consumption, expanding the applicability of ODC technology to regions with lower power costs. Oxygen gas is an additional input to the process and hydrogen gas is eliminated as an output, which reduces the energy of the reaction. This is combined with the lower energy metal chloride reaction with ethylene gas to produce ethylene dichloride. We partnered with Covestro and successfully tested the ODC technology at our pilot plant. These experiments exemplified the ODC synergies with our eShuttle® platform.
