Taking the existing one-phase expanders to the next level, two-phase machines operate at sub-bubble point outlet pressures which make them ideal for mixture distillation processes such as nitrogen rejection. Differing from a single-phase machine, a two-phase expander may be used in any liquefaction process in which large downstream pressures are not required in order to extract more energy from the liquid. By doing so, process efficiency can be increased from an approximated 5% up to 8%.
In operation since 2003, EIC two-phase liquid expanders use the same TEM® and submerged motor/generator technology proven in our line of cryogenic pumps.
