... is to the right of the critical point, but to the left of the maximum temperature of the phase loop, the system exhibits retrograde behavior; components can condense out of the vapor phase, at reservoir temperature, as the pressure is reduced. This phenomenon differentiates between a wet gas and a gas condensate...
