14. A gas separating system comprising:
a plurality of separation vessels, each receiving gases and liquids exiting from a different level of a vertical retort configured for hydrocarbon extraction from shale and configured in a zig-zag pattern, wherein gases and liquids of different levels of the vertical retort exit the vertical retort at different temperatures so that each of the separation vessels receives gases and/or liquids at a different temperature than other of the plurality of separation vessels;
a last separation vessel configured to condense water;
connecting piping fluidly connecting each of the plurality of separation vessels and the last separation vessel in series from a highest temperature separation vessel to a lowest temperature separation vessel and then to the last separating vessel, such that a gas outlet of a higher temperature separation vessel is connected via the connecting piping to an inlet of a lower temperature separation vessel of the plurality of separation vessels and an outlet of the lowest temperature separating vessel is connected via the connecting piping to an inlet of the last separation vessel; and
one or more heat exchangers in each of the plurality of separation vessels and the last separation vessel, wherein a circulating fluid of a separation vessel of the plurality of separations vessel and the last separation vessel circulates at a temperature to condense liquid and gas in the separation vessel, wherein the one or more heat exchangers of each of the plurality of separation vessels and the last separation vessel operates at a different temperature.
