Abstract

According to one embodiment of the invention, a jet ejector method includes providing a primary jet ejector having a primary inlet stream, coupling one or more secondary jet ejectors to the primary jet ejector such that all of the jet ejectors are in a cascaded arrangement, bleeding off a portion of the primary inlet stream and directing the portion of the primary inlet stream to the secondary jet ejector that is closest to the primary jet ejector in the cascaded arrangement, and directing a motive fluid into the secondary jet ejector that is farthest from the primary jet ejector in the cascaded arrangement. The method further includes, at each secondary jet ejector, receiving at least some of the portion of the primary inlet stream and at least some of the motive fluid to create respective mixtures within the secondary jet ejectors, and at each secondary jet ejector, directing at least a portion of the respective mixture to adjacent jet ejectors in the cascaded arrangement.
