Abstract

Ethylene production requires high energy costs, and the composition of the ethanol feed is not very pure. The aim of this research is to reduce energy costs slightly while still increasing conversion to obtain a purer ethanol conversion. To achieve this goal, the method used is to add one more heat exchanger and one more reactor. The results obtained turned out that by adding a heat exchanger, we do not need cooling water, but can utilize the output of cryogenic distillation. An energy efficiency of 73.56% obtained and the ethanol conversion obtained was also close to pure with the presence of two reactors with a value of 99.2%. Further process creation is needed to be able to optimize the ethylene production process which is more environmentally friendly, such as making ethylene with bioethanol as feed.

Abstract

Benzene is a chemical raw material that is widely used without alternatives in the production of high energy solid liquid fuels and polymers. As a result, the global demand of benzene reaches 51 million per year. The process simulator has been utilized to simulate the reactor system of benzene production through the hydrodealkylation of toluene using Peng-Robinson equation-of-state property package. This system is designed to reach 200,000 tons of benzene per year with an optimized heat flow mechanism. By using a heat recovery strategy that utilizes the heat stream outlet from the waste heat boiler (WHB-01) and the partial condenser (PC-01), the net-energy in the simulation has been effectively minimized by saving a total of -23,915,490.40 kJ/h by directing the heat streams to heaters H-01 and H-02, respectively. Considering this strategy, the modified process within the reactor system is conclusively more optimized than the basic process system.

Abstract

Global production of formaldehyde has consistently risen over the past ten years, highlighting its extensive industrial applications and high demand across various sectors worldwide. However, its production continues to consume a significant amount of energy. The aim of this paper is to investigate and propose strategies for enhancing energy efficiency in formaldehyde production processes. Specifically, the study focuses on harnessing heat from the reactor's outlet stream to minimize the energy consumption associated with heat exchangers. By analyzing and optimizing the utilization of this heat source, the paper aims to contribute to sustainable manufacturing practices by reducing overall energy requirements and operational costs in formaldehyde production facilities. The process modification was simulated using Aspen HYSYS and the comparison of net-energy between the basic and the modified process is calculated using the net-energy formula. The results obtained that the Net-Energy (NE) value for both basic and modified process is 316,286,815.4 kJ/h and 125,757,792.9 kJ/h. This shows that the modified process has better energy efficiency compared to the basic process as the net-energy value zero. Therefore, this modification enhances the energy efficiency of the formaldehyde production process through methanol oxidation.

Abstract

Acetic acid finds extensive application in the food, chemical, pharmaceutical, polymer, paint, and textile industries. Considering these applications, acetic acid production needs to be optimized for high efficiencies in both energy and mass in order to maximize profit. In this work, we will be explaining how one could maximize the yield of acetic acid and show results on purity analysis. By modifying the process, the previous reactor was replaced, and the separation unit was removed. Whereas case study tools in Aspen HYSYS V12 were used in order to carry out the purity analysis of the current modified process. According to these process modifications, the acetic acid yield increased from 85.00% to 100% purity. The results of the case study of acetic acid production indicate that the higher the mole fraction ratio of acetic acid to the total product mole fraction, the higher the purity of the liquid product produced from the reactor. Conversely, if the mole fraction ratio of acetic acid to the total product mole fraction decreases, the purity of the liquid product will be reduced, which means that an increase in the mole fraction of by-products or contaminants occurred in the mixture.

Abstract

Sulfuric acid is a strong mineral acid and is useful for processing mineral ores, chemical synthesis, waste water processing, and others. The increasing need for sulfuric acid is not balanced with the amount of sulfuric acid production due to the use of quite a lot of energy in the production process. Therefore, innovation is being carried out, namely energy efficiency in sulfuric acid production from sulfur and air, which is expected to help increase production of sulfuric acid so that it can meet market needs. The sulfuric acid production process uses a contact process which is carried out with 3 reaction stages where the raw materials in the form of sulfur and free air are reacted in the reactor and SO2 gas is obtained, then SO2 reacts with oxygen to form SO3 gas in the converter bed, and finally the formation of H2SO4 from the reaction between SO3 and water in the absorber column. Modifications were made using Aspen HYSYS to improve energy efficiency in the sulfuric acid production. Copyright © 2025 by Authors, Published by Universitas Diponegoro and BCREC Publishing Group.

Abstract

Styrene is a crucial unsaturated aromatic monomer with a wide range of industrial applications. Styrene production faces several problems where the water supply and energy usage are keep increasing. Process modifications were implemented to minimize process water and to optimize the energy consumption. The modification uses Aspen HYSYS simulation by replacing coolers and heaters with heat exchanger and implementing water recycling system. Aspen HYSYS simulations show these changes reduce water usage by 89.8% and significantly decrease energy consumption up to 54.69%. This modification shows the water and energy usage have been significantly reduced than the basic process. Copyright © 2024 by Authors, Published by Universitas Diponegoro and BCREC Publishing Group.

Abstract

Formaldehyde is one of the chemical products that has an important role in various industries with the percentage of global production consistently increasing over the past ten years. However, the production of formaldehyde requires considerable energy consumption. The purpose of this study is to examine other alternatives to improve energy efficiency in the formaldehyde production process. This study focuses on the reutilization of heat generated from the heat exchanger to minimize the net energy generated. The process modification was simulated using Aspen HYSYS and the net energy comparison between the original and modified process was calculated using the net-energy formula. The results show that the Net-Energy (NE) value for the original process is 18,839,836 kJ/h while for the modified process it is 4,123,000 kJ/h. This result shows that the modified process is efficient to reduce Net-Energy and can increase energy efficiency in the formaldehyde production process through the methanol dehydrogenase process.

Abstract

Cyclohexane is a compound that is widely used in various industrial applications as a chemical intermediate. Apart from that, this compound can also be used to produce solvents, insecticides and plasticizers. With the large use of cyclohexane, production with high efficiency in terms of yield is required. The aim of this research is to develop a process design for producing cyclohexane from benzene hydrogenation, with the aim of achieving high yield. This research uses an iterative simulation method to compare the basic process and a modified process for cyclohexane production. This process involves creating a simulation model using Aspen HYSYS and adjusting the process parameters until the desired results are achieved. The results of this research indicate that the cyclohexane produced in the modification process achieves a higher percentage of yield product. Based on the implemented process modification, there has been an increase in the yield of cyclohexane produced from 93.49% to 99.90%. Based on the results of this research, the modification process is proven to be able to increase yield and mass flow compared to the basic process system.
