Abstract
A pumping system comprises an internal combustion engine, a generator, a pumping unit and a heat recovery system. The generator is driven by the internal combustion engine. The pumping unit is powered by the generator. The heat recovery system thermally couples the internal combustion engine with the pumping unit.
Claims36
A system comprising:
- an internal combustion engine;
- a generator driven by the internal combustion engine;
- a pumping unit powered by the generator wherein the pumping unit comprises:
- a first pump configured to receive a first fluid component;
- a second pump configured to receive a second fluid component;
- a manifold configured to receive the first and second fluid components from the first and second pumps;
- and
- a dispenser that receives the first and second fluid components from the manifold, the dispenser having a mix head that mixes the first and second fluid components;
- and
- a heat recovery system thermally coupling the internal combustion engine with the pumping unit, wherein the heat recovery system scavenges heat generated by the internal combustion engine and delivers the scavenged heat to the pumping unit to separately heat the first fluid component and the second fluid component prior to mixing of the first and second fluid components by the mix head.
