The Methodology and Benefits of Total Site Pinch Analysis
The Methodology and Benefits of Total Site Pinch Analysis Introduction As the demands on refiners to increase profitability and reduce emissions continue, many companies are focusing on improving energy efficiency to provide attractive solutions. It is clear how improving energy efficiency can benefit in profitability by considering the cost of energy. Refinery energy costs vary greatly depending on refinery configuration and location, but typically may range between $40-100 million/year for a 200,000 BPSD refinery. Improving the efficiency by only a few percent, therefore, has obvious financial rewards. Similarly, as the majority of the energy cost is associated with fuel, any percentage improvement in efficiency corresponds to an equivalent reduction in emissions caused by burning fuel (i.e. CO2, SO2, NOx etc.).
