A vapor recovery apparatus consumes a source of liquified gas (LN) to condense vapors (5) in a source of vapors. The apparatus includes an economizing heat exchanger (30) and a finishing heat exchanger (10). The economizing heat exchanger has a vapor path adapted to be connected to the source of vapors (44), and a recovery path (27) for exchanging heat with, and cooling vapors in, the vapor path. The finishing heat exchanger has a finishing path connected downstream of the vapor path of the economizing heat exchanger, and a coolant path adapted to be connected to the source of liquified gas (14) for cooling and condensing vapors in the finishing path. The coolant path is isolated from the finishing path to avoid interpath mixing. The finishing path is connected to feed the recovery path of the economizing heat exchanger. |
