Title: Innovations by Muthusamy Rajendran in Cryogenic Technologies

Introduction

Muthusamy Rajendran, an accomplished inventor located in Manchester, Connecticut, holds two patents that showcase his innovative contributions to cryogenic technology. His work focuses on developing efficient machinery that operates effectively in extreme temperatures, particularly in gas liquefaction applications.

Latest Patents

Rajendran's latest patents include a cryogenic oil-free direct drive turbogenerator and a hermetically-sealed turbomachine designed for high-temperature operation.

The cryogenic oil-free direct drive turbogenerator is engineered for gas liquefaction plant applications. It utilizes the pressure energy from cryogenic gas, which is expanded through a turbine. The energy generated is converted into electricity using a directly driven generator and an advanced power electronics arrangement. This innovative machinery is capable of enduring extremely low temperatures (e.g., below –425°F) by isolating the cold turbine side from the warmer side and featuring a hermetically sealed design that prevents gas leakage. Notably, a unique gas injection scheme ensures thrust control through a pressure regulator system, while an algorithm for speed control and overspeed protection enhances its operational safety. The rotating components utilize foil gas bearings, which allow for oil-free operation, eliminating the need for lubrication.

Rajendran’s other patent, concerning mechanically-coupled turbomachinery configurations, focuses on a hermetically-sealed turbomachine suitable for reliable high-temperature operations. This design incorporates a thermal choke assembly that separates the hot blower or turbine end from the cooler electric motor or generator end. The turbomachine’s housing is hermetically sealed to manage the process gas effectively within, allowing a portion of this gas to cool the internal components. The cooling efficiency can be enhanced via an operatively linked heat exchanger, optimizing both performance and reliability.
