Abstract
A shell-tube bundle heat exchanger is so arranged as to leave a section within the shell devoid of tubes. Into said section relatively hot vapors are introduced to be mixed with chilling medium within said shell and surrounding said tubes. A baffle means is provided to prevent liquid disturbed by introduction of the vapors from transmitting disturbance to the cooling medium surrounding the tubes. In one embodiment, propane vapors under pressure are introduced under the surface of cold liquid propane in a horizontal gas chiller. A stilling leg or vertical baffle is located between the tubes and the point of introduction of the vapors introduced through a slotted vapor inlet pipe. A liquid level sensing and/or control means is also baffled away from the point of introduction of vapors.
