Elliott Group products

Elliott Group delivers state-of-the-art gas compression performance in a diverse range of hydrocarbon markets including oil and gas production and processing, petroleum refining, petrochemical processing, cryogenic refrigeration (LNG) and other industrial processes. 

Over the course of more than 40 years, Elliott has designed and built hundreds of axial compressors. Elliott`s axial compressors are often paired with Elliott power recovery expanders to supply combustion air to the fluid catalytic cracker process (FCC). These highly efficient and reliable machines are well suited for high flow, medium pressure applications beyond the flow capacity of centrifugal compressor designs such as FCC service, air separation, blast furnaces, wind tunnels and synthetic fuel processes.

Exercising a trip valve regularly can mean the difference between a turbine tripping when necessary and catastrophic failure. Over time, steam impurities and contaminants can cause boiler scale or rust buildup that could result in the trip valve not working properly when necessary.

The unique design of the in-tank (retractable) pump allows it to be installed inside a storage tank in a vertical pump column with a suction (foot) valve located at the bottom. Because the pump is installed through the top of the tank, all connections below the maximum liquid level of the tank can be eliminated. This design eliminates the possibility of major tank leakage because of a pipe or connection problem, and also permits the storage vessel to be located below ground level.

The pump and motor assembly of the suction vessel mounted pump is contained within a suction vessel built to the appropriate pressure vessel code for each application, making the installation safe, simple, and reliable. The suction vessel functions as the outer pump casing. It is fabricated with a suction nozzle, welded couplings (for drain and liquid level indication), support brackets, a head plate with discharge nozzle, a conduit for electrical cables, and a vent nozzle. The result is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps.
