Abstract: The invention provides a process and a plant for the production of ε-caprolactam and crystalline ammonium sulfate in an industrial-scale plant, wherein the plant comprises a Beckmann rearrangement reaction section, an ammonium sulfate crystallization section, and one or more heat exchangers configured to transfer heat from the Beckmann rearrangement reaction section to the ammonium sulfate crystallization section and wherein the process comprises the steps of: a) feeding (i) cyclohexanone oxime and (ii) oleum and/or sulfuric acid to the Beckmann rearrangement reaction section b) reacting components (i) and (ii) in the Beckmann rearrangement reaction section to form a reaction mixture comprising ε-caprolactam, whereby heat of reaction is generated; c) discharging the reaction mixture comprising ε-caprolactam from the Beckmann rearrangement reaction section; d) removing partially or fully the heat of reaction generated in the Beckmann rearrangement reaction section by one or more heat exchangers configured to transfer heat from the Beckmann rearrangement reaction section; e) feeding an aqueous liquid comprising ammonium sulfate to the ammonium sulfate crystallization section; f) introducing heat into the ammonium sulfate crystallization section comprising the aqueous ammonium-sulfate-comprising liquid by one or more heat exchangers configured to transfer heat into the ammonium sulfate crystallization section; g) forming ammonium sulfate crystals by evaporative crystallization in the ammonium sulfate crystallization section; characterized in that h) the heat of reaction removed from the Beckmann rearrangement reaction section in step d) is at least partially or fully transferred to the ammonium sulfate crystallization section in step f).

Abstract: A power supply device, a photochemical reaction device and method in which the power supply device is used, and a lactam production method in which the photochemical reaction method is used, the power supply device being characterized by having a control circuit for controlling the current from a power supply source, a cooling means capable of cooling the surroundings by channeling a refrigerant, a heat transfer means connecting the cooling means and the control circuit to each other, and an insulating means interposed between and in contact with the heat transfer means and the control circuit. It is possible to prevent an excessive increase in temperature of the control circuit, stably maintain the function of the control circuit, and extend the lifespan of electric and electronic components mounted on the control circuit. Applying this power supply device makes it possible to build a high-output and high-integration type LED light source device, and operate the light source device in a stable manner over a long period.
