Abstract
The non-uniformity of flow rate distribution between separate devices of the plate-fin heat exchanger units working as a part of air separation plant, exceeding 2% of the nominal value, significantly reduces integral characteristics of the unit. Shortcomings of the method for regulating uniformity of flow rate distribution in the plate-fin heat exchanger units by means of regulating valves are considered. It is suggested to use a different approach allowing to avoid the use of expensive regulating valves and to specify the conditions to provide the required uniformity of flow rate distribution between separate heat exchangers already at the preliminary design stage.
