Latest Patents

One of his latest inventions is the Flameless Nitrogen Skid Unit. This innovative vaporizing unit features a first internal combustion engine that drives a nitrogen pump through a transmission. A second internal combustion engine powers three hydraulic oil pumps against a variable back pressure, allowing for a variable load on the second engine. Liquid nitrogen is pumped from the nitrogen pump into a first heat exchanger, where heat is transferred from the exhaust gases of both engines to transform the nitrogen into a gaseous state. The gaseous nitrogen then flows into a second heat exchanger, where it is superheated by engine coolant fluid to reach ambient temperature before being injected into the well. The coolant fluid circulates through a system that includes a comingling chamber, ensuring efficient heat transfer and operation.
