炼厂油品储运系统的能耗占全厂总能耗的 7％～10％。以 2500 kt/a的燃料 型炼厂为例,储运能耗一般约在167.5～250 MJ/t(原油)。从能源结构上可分为蒸汽、电、水三部分,其中蒸汽消耗的能量约占80％～85％,电约占 16％～18％,水约占1％～2％。油罐加热所用蒸汽占全部汽量的60％～65％,其余为管线伴热、换热器所用。降 The energy consumption of the refinery oil storage and transportation system accounts for 7% -10% of the total energy consumption of the whole plant. Taking a 2500 kt / a fuel-based refinery as an example, the energy consumption of storage and transportation is generally about 167.5 to 250 MJ / t (crude oil). From the energy structure can be divided into steam, electricity, water three parts, of which steam energy consumption accounts for about 80% to 85%, electricity accounts for about 16% to 18%, water accounts for about 1% to 2%. The steam used for heating the oil tank accounts for 60% ~ 65% of the total steam volume, and the rest is the heat tracing for the pipeline and the heat exchanger. drop
