Title: Innovations of Krishnan Viswanathan

Introduction

Krishnan Viswanathan is a notable inventor based in Niagara Falls, NY (US). He has made significant contributions to the field of chemical engineering, particularly in the production of ethylene and the prevention of cathode corrosion in chlor-alkali diaphragm cells. With a total of 4 patents to his name, his work has had a substantial impact on industrial processes.

Latest Patents

One of his latest patents is titled "Process for the production of ethylene and mixture containing ethylene." This invention provides an efficient method for producing ethylene or a mixture of ethylene and vinyl chloride by reacting chlorine with ethane. The process is characterized by a conversion of ethane per pass through the reactor of at least about 50%, and a combined molar yield of ethylene and vinyl chloride of at least about 80% based on the ethane consumed.

Another significant patent is the "Method for preventing cathode corrosion." This method addresses the dissolution of transition metal-based cathodes used in chlor-alkali diaphragm cells. By adding a small amount of a corrosion inhibitor, such as sodium silicate or trisodium phosphate, to the electrolytic solution during periods of interrupted current flow, the cathode is protected. The corrosion inhibitor forms an adherent protective film on the cathode, preventing the dissolution of the transition metal due to oxidation by sodium hypochlorite.
