Introduction

Francis A. DiBella is a notable inventor based in Roslindale, MA, who has made significant contributions to the field of hydrogen gas compression systems. With a total of seven patents to his name, DiBella's work focuses on enhancing the efficiency and capacity of hydrogen gas compression technologies.

Latest Patents

One of DiBella's latest patents is for high-flow-capacity centrifugal hydrogen gas compression systems, which include multistage centrifugal compressors. Each stage of these compressors has an inlet-to-outlet pressure rise ratio of about 1.20 or greater. In one embodiment, the multistage compressor consists of six high-speed centrifugal compressors that operate at a speed of approximately 60,000 rpm. This innovative design allows for an output of more than 200,000 kg/day at a pressure exceeding 1,000 psig. The compressors are strategically distributed on both sides of a common gearbox, which effectively manages axial thrusts. Each compressor stage features a unique impeller secured to a support shaft using a tension-rod-based attachment system. Additionally, another embodiment of the multistage compressor is driven by a combustion turbine, with intercoolers provided between compression stages, utilizing coolant from an absorption chiller that employs exhaust gas from the combustion turbine.
