Abstract
Integrations of carbon monoxide electrolyzers and chlor-alkali electrolyzers are disclosed herein. The disclosed integrations include novel process chains for the valorization of oxocarbons into hydrochloric acid, vinyl chloride, vinyl acetate, ethylene oxide, and other useful chemicals. The disclosed integrations further include novel ways to operate the electrolyzers in tandem to increase the efficiency of both reactors. This disclosure also includes novel ways to balance the operation of both electrolyzers to assure they are operating at an optimal level to take advantage of the benefits of the disclosed integrations.
