ABSTRACT = {It is important to determine the insulation thickness in the design of the
buried hot oil pipelines. The economic thickness of the insulation layer not only
meets the needs of the project but also maximizes the investment and environmental benefits. However, as a significant evaluation, the environmental factors
haven’t been considered in the previous study. Considering this factor, the mathematical model of economic insulation thickness of the buried hot oil pipelines is
built in this paper, which is solved by the golden section method while considering the costs of investment, operation, environment, the time value of money. The
environmental cost is determined according to the pollutant discharge calculated
through relating heat loss of the pipelines to the air emission while building the
model. The results primarily showed that the most saving fuel is natural gas, followed by LPG, fuel oil, and coal. The fuel consumption for identical insulation
thickness is in the order: coal, fuel oil, LPG, and natural gas. When taking the
environmental costs into account, the thicker the economic insulation layer is,
the higher cost it will be. Meanwhile, the more pollutant discharge, the thicker
the economic insulation layer will be.},
