Preliminary reactor design for gold nanoparticle production by the Turkevich method on an industrial scale

This study aims to design and analyze the design of a batch-type reactor to optimize the production of gold nanoparticles on an industrial scale. The method used in the design of this reactor is the computational analysis of the reactor calculations, including stirring and mass balance as initial calculations using the Microsoft Excel application manually. The calculation results show that the designed reactor specifications have a reactor volume of 21.7335 ft3, cylinder height of 13.4612 in, a height of solution in the cylinder of 8.9046 in, vessel diameter of 73.2984 in, design pressure of 9.9978 psig, impeller length of 9.1840 in, shaft length of 10.5418 in, with stirring power 62.5228 Hp. Reactor design analysis is an important stage in the design of production processes on an industrial scale, where the specification results from the designed reactor can be used not only to adjust the reactor to the product but also to be used as a reference for production costs. The results of computational analysis and calculations performed on the reactor design in this study can be used as a reference and can be applied in the design of reactor performance analysis as a learning media, including operating mechanisms in the production process.
