Abstract
An energy conservation study has been undertaken on a hydrofiner unit in an oil refinery. The results in energy terms and overall financial savings have been discussed in a previous paper by Holland and McKay (1981). However, a critical financial appraisal of the various proposed schemes was not undertaken. This paper compares the proposed energy conservation measures by various costing techniques, including: 1. (i) return on investment; 2. (ii) pay-back method; 3. (iii) net present value; 4. (iv) internal rate of return.
