Design Heat Exchanger Type Shell-Tube Mathematically With 2-Butanol Hot Fluid and Cold Fluid Steam for the Production of MEK
Purpose: This study aims to analyse and develop design a heat exchanger (HE) for the production of Methyl Ethyl Ketone (MEK) which will be compiled into a computational program for the design of shell-tube type HE.
Methodology: The problem with this HE is that the temperature of 2-butanol is 30?C from the storage tank. While the HE reactor requires a temperature of 99.6?C, HE plays a role in increasing the temperature from 30?C to 99.6?C. To be more energy efficient, researchers used heat of the product, MEK. Which is where to exchange heat from the product to the reactants. The design of a shell-tube two-pass exchanger with a working fluid in the form of 2-butanol as a hot fluid with water as a cold fluid. The HE specification on the shell size for the pressure drop is 4.9959E-06 psia, while the tube size for the pressure drop is 2.6550E-04 psia. The effective value of 14%.
Results: Thus, HE with shell and tube doesn’t meet the requirements and standards of TEMA. Although the shell and tube type of HE doesn’t conform to the criteria and standards specified in industrial applications, the analysis can be used as a learning tool for the design process, heme performance analysis, and operating mechanism of the HE.
Limitations: This research is focused on developing HE designs for the production of MEK.
Contribution: This research can provide a reference for designing HE in industrial development.

SintaThe Development of Strontium Titanate Nanoparticle Research: A Bibliometric Computational Mapping Analysis
Purpose: The aim of this study was to determine the progress of research on Strontium Titanate (SrTiO3) nanoparticles through a bibliometric approach and also using computational mapping analysis using VOSviewer.
Methodology/approach: The keyword “SrTiO3 nanoparticle, Strontium Titanate” is used, then the article is selected based on the title and abstract. We conducted an analysis of articles discussing SrTiO3 nanoparticles and their relationship to problem areas using VOSviewer.
Results/findings: A total of 667 relevant articles were found based on these keywords. Articles used in the last 11 years, from 2012 to 2022. The results showed that SrTiO3 nanoparticles can be divided into 3 fields: “SrTiO3” with 163 links and 1092 total link strength, “Nanoparticle” with 175 links and 1697 total link strength, and “Strontium Titanate” with 170 links and 1459 total link strength. It was found that the research trend of SrTiO3 nanoparticles was increasing. In 2012 to 2015 there was an increase from 29 articles in 2012 to 46 articles in 2015. There was a decrease from 2015 to 40 articles in 2016. From 2016 to 2022 there was a significant increase in the number of articles from 40 articles in 2016 to 93 articles in 2022.
Limitations: This study did not discuss in depth the relationship between the terms in this SrTiO3 nanoparticle study.
Contribution: The results of this study can be used as a reference to find out the trend of research on nanoparticle materials which has increased, so that it can be a potential for further development of SrTiO3 nanoparticle applications.
