Abstract

This study aims to develop and analyze the design of heat exchangers (HE) in the synthesis of PbO particles using a single precursor method. This type of HE shell and tube one-pass is designed to be simple. The specifications of HE equipment are shell length 1.5200 m, shell diameter 0.1361 m, outer tube diameter 0.0334 m, and thickness 0.0243 m. Then the calculation is done manually using the Microsoft Excel application. The results showed that the HE shell and tube design with the one pass type has a laminar flow, with an effective value of 84.66%. Therefore, this heat exchanger with shell and tube one meets the requirements and standards based on effectiveness, but without considering the fouling factor. The results of this analysis can be used as a learning medium in the design process, analysis of heat exchanger performance, and operating mechanisms.

Abstract

This study aims to examine the development of research on cadmium sulfide (CdS) as a catalyst with a bibliometric approach using computational mapping analysis using the VOSviewer application. To support research, a reference manager application (Publish or Perish) is used to obtain article data from the Google Scholar database. The keyword "Cadmium Sulfide as a Catalyst" is used to guide the search process for the title and abstract of the article. There were 999 articles considered relevant. Articles used as study material are articles indexed in Google Scholar for the last 10 years of study period (2013 to 2022). The results of the analysis of the development of the publication of cadmium sulfide as a catalyst in the last 10 years show quite frequent fluctuations. Research fluctuations occurred from 2013 – 2015 (61, 89, 67 publications per year, respectively). In 2016 – 2019 there was an increase in research (81, 91, 94, 117 publications per year, respectively). In 2020 – 2022 there will be research fluctuations (113, 155, 131 publications per year sequentially). VOSviewer was used to determine the relationship between the number of published articles on cadmium sulfide as a catalyst and problem areas. This review can serve as a starting point for research related to other materials
