Abstract
A process for automatically venting noncondensable contaminants from a number of process vessels heated with an organic heat transfer vapor medium involves monitoring the temperature at each vessel and intermittently venting all vessels simultaneously in response to a temperature drop at any one vessel. By venting intermittently for a predetermined period energy is conserved. Equipment costs are minimized by simultaneous venting through a single control valve.
