Heat exchanger design for the production of synthesized gold nanoparticles
Abstract
This study aims to develop and analyze the design of heat exchangers in the production of gold nanoparticles (AuNPs) by the biosynthesis method using Sargassum horneri (SH) extract. The simple design of this heat exchanger (HE) uses the shell and tube type, the onepass tube, and the fluids are water. These specifications pertain to the design of a heat exchanger (HE). The tube length of 4.267 m, shell diameter of 254 mm, outer tube diameter of 22.225 mm, inner tube diameter of 21.184 mm, and wall thickness of 2.1082 mm describe the physical dimensions of the tubes in the heat exchanger. The pitch tube of 31.75 mm refers to the distance between the centers of adjacent tubes in the heat exchanger. Based on manual calculations using Microsoft Excel, the results show that this design has laminar flow as indicated by the Reynolds value. In addition, the HE designs has an effectiveness value of 98.98% with an NTU value of 11.50. In this study, the HE designs results have a high effectiveness value, so it can be considered effective for use in producing gold nanoparticles with SH extract. Therefore, this HE designs analysis can be used as a learning medium in the HE designs process, the operating mechanism, and the performance analysis of the HE.
