比较了两种工厂概念光化学合成ε-己内酰胺的能量需求。传统的灯驱动概念遵循日本东丽有限公司在工业规模上实现的过程，太阳能概念的设计具有相同的年产量。比较的目的是确定如果光化学能够利用太阳辐射而不是人造光，可以节省化石燃料。与同等的传统操作路线相比，利用太阳辐射进行己内酰胺的光化学生产，对电流的需求降低了4倍，对冷却能量的需求降低了8倍。此外，由于避免将化石燃料转化为电流，太阳能过程将允许每吨己内酰胺排放1.5-2.5吨二氧化碳，这取决于所使用的主要能源载体。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
The energy demand of photochemical synthesis of E-caprolactam was compared for two plant concepts. The conventional lamp-driven concept followed the process as realized on an industrial scale by Toray Ltd, Japan and a solar concept was designed at identical yearly output. The aim of the comparison was to determine the savings of fossil fuels that could be achieved if photochemistry could make use of solar-radiation instead of artificial light. The use of solar radiation for the photochemical production of is an element of-caprolacram has a 4-fold lower demand for electric current and an 8-fold lower demand for cooling energy as compared to an equivalent conventionally operated route. Furthermore, due to avoided conversion of fossil fuel to electric current, a solar process would allow specific emissions of 1.5-2.5 tons of CO2 per ton is an element of-caprolactam to be avoided, depending on the primary energy carrier used.
