Abstract
An apparatus and method for cooling a gas stream is provided comprising at least one heat exchanger in which a gas stream is cooled against a cooling liquid, whereby the cooling liquid temperature increases from a first temperature to a second temperature, at least one air cooler for cooling the cooling liquid after passing though the at least one heat exchanger, surface area of the at least one air cooler being designed to decrease temperature of the cooling liquid to the first temperature; a pump; and conduits to form a closed-circuit for the cooling liquid to pass continuously through the at least one heat exchanger and the at least one air cooler. The ratio of surface area of the at least one air cooler to the surface area of the at least one heat exchanger is optionally 12 or lower, and the difference of temperature between the second temperature and first temperature being greater than 15° C.
