Abstract
An improved method and apparatus is disclosed for removing condensable material from a gas. The gas is caused to flow in series through a chiller for cooling the gas and condensing the condensable material from the gas, then through a separator to separate the condensate from the gas, and then passing the gas through a reheater to reheat the gas. A predetermined charge of refrigerant is passed in a closed cycle through the chiller to cool the gas by absorbing the heat from the gas and evaporating, then the gaseous refrigerant is compressed by a compression unit having an electric drive means in which an amount of energy is added to the gaseous refrigerant. The hot, pressurized, gaseous refrigerant is then passed through an auxiliary condenser sized to remove the energy that was added to the refrigerant by the compression unit at no load conditions, then the refrigerant is passed through the reheater to further condense the refrigerant and to transfer heat to the exiting gas. The refrigerant then exits the reheater and returns to the chiller, completing the closed cycle. The predetermined charge of refrigerant is sized to cause the refrigerant exiting the reheater to be in a substantially gaseous state when there is no flow of gas through the reheater and to cause the pressure of the refrigerant exiting the reheater to generally decrease as the flow of gas through the reheater increases.
