Abstract
A positive result of the oil crisis of the seventies is the realisation of energy’s value and the need to use it sparingly. Increasing attention has been focussed on all aspects of industry where fuel oil and gas had played a major role.
Industrial drying, one of the most widely applied unit operations in chemical and process engineering, is a highly energy intensive operation. Studies have identified a number of alternatives for lowering energy consumption in this process through various heat recovery techniques.
Due to the difference in their operating principles steam-heated dryers and air-heated dryers, in most aspects, require different techniques of energy recovery.
This paper examines the feasibility of applying Mechanical VAPOUR RECOMPRESSION (MVR) in recycling the heat in the exhaust vapours of steam-heated dryers. Operating costs of MVR - assisted dryers are compared to those of conventional steam dryers and it is shown that considerable savings can be attained with a payback period of two to three years expected from the considered case study.
