Energy Saving

Global demand and government legislation is focussing attention on achieving energy reduction to meet both economic and environmental expectations. Processes must be operated at optimum performance to achieve higher levels of energy conservation through increased thermal efficiency . Heat recovery technology and improved equipment design are the corner stones to meet these demands whilst gaining reductions in production costs.

Systematic design tools such as pinch technology can assist in identifying energy recovery targets for both existing plants and grassroots designs.  However, the actual plant efficiency will tend to fall below target due to economic constraints.  Higher energy efficiency is always possible, but the required heat exchangers may be too expensive to justify the additional heat recovery.  hiTRAN Thermal Systems help to shift the economic balance in favour of increased heat recovery by reducing the cost of additional thermal capacity. In new plants the size and cost of heat exchangers can be reduced, while in retrofit additional heat recovery can be engineered without changing the process flowsheet.

Cal Gavin engineers are experienced in the creative application of heat transfer enhancement techniques to identify and deliver energy savings within realistic investment criteria.  In many cases multiple benefits are obtained, including increased throughput, improved product quality and longer run times.
