Optimization of Energy Consumption and Study of New Heater Installation in Distillation Units of BandarAbbas Refinery with CDM

Energy efficiency practices that started worldwide in 1970s contain three important themes including energy, economic and environment. Developed countries have been benefited from energy efficiency measures. Today, industrial countries consider energy efficiency as anew source of energy. Implementation of energy efficiency management has resulted in better development of industrial, economic and also cultural consumption. In the present investigation, energy consumption was measured at heaters and boilers of the Bandar Abbas Refinery. Considering the input energy and its comparison with the output energy at heaters and also higher costs associated with repairs and also damages incurred due to the overload conditions at distillation units, it is very essential to investigate the costs and benefits. Herewith, we suggest installation of the second heater at distillation units to increase the efficiency rate as well as to subsidize the pressure on the present working heaters. We have evaluated the installation of new heater using Proform Software to analyze the economic and also the return period of capital investment. This was done at different scenarios considering various aspects such as carbon tax coupons, and natural gas prices at international markets. The output of the software is highly dependent on the price of natural gas and other factors do not affect the output of software considerably. It is evaluated that gas price of US$ 5.7 per giga-jule makes the investment economical and for the scenario of US$ 22/ton of CO, the capital investment return would be 3.3 years. It will be 3.6 and 3.7 years for C02 rates ofUSS 7 and US$ 3. If carbon trading is not considered at all, the return period will increase to 3.8 years. This utilization of Clean Development Mechanism (CDM) is economical .Nevertheless the final decision must be taken by policy makers in the present situation.
