Abstract:
1. A system for supplying dry gas to machinery seals, comprising: a gas recirculation loop, comprising: a source of rotational force in communication with the driven rotary separator; a heating unit positioned downstream from the gas recirculation loop and configured to heat the gas stream to a temperature above the dew point of the liquid; and a control valve disposed between the booster and the heating unit, the control valve configured to move between an open position and a closed position, the control valve in the open position allowing fluid flow out of the recirculation loop and to the heating unit, and the control valve in the closed position prohibiting fluid flow to the heating unit, such that the fluid flow from the booster is recirculated back to at least one of the cooling unit, driven rotary separator, and booster.
