Abstract

Methanol is extensively used in the various products, including plastics, paints, adhesives, and synthetic fibers. With the many uses of methanol, its production must have high efficiency both in terms of energy and mass in order to obtain maximum profits. In this paper, we will explain how to reducing energy consumption and maximize methanol product yield by modifying the methanol synthesis. The process modification was carried out by adding heat exchanger, distillation column unit and recycle stream. Case study tools on chemical engineering software were used. Based on process modifications, an increase in methanol yield was obtained from 97.47% to 99%, the total energy savings from this process after adding distillation column is 57.618 × 106 kJ/h or 58.5% of the total initial energy, and with recycle stream the syngas produced reached 5.419 kgmol/h while without recycle stream, the syngas produced was only 4.157kgmol/h. The results of the case study indicate that the addition of heat exchanger, distillation column, and recycle stream is beneficial for the methanol production process by reducing the energy and increasing mass efficiency.

Abstract

Formaldehyde is a substance that has been utilized for a long time due to its numerous benefits. This research article focuses on optimizing energy consumption in formaldehyde production from methanol using metal oxide catalysts. The Formox process is one of the main methods for formaldehyde production through the partial oxidation of methanol with metal oxide catalysts. In this process, energy released by the system is recovered and reused, making the overall energy consumption more efficient and reducing the required costs. By reducing the energy consumed in the production process, emissions released into the atmosphere will decrease, and profitability can be enhanced by lowering energy-related costs. The energy results before modification show a value of 43,030,653.8 kJ/h, while the modified system yields 26,766,429.7 kJ/h, achieving an energy efficiency improvement of 37.8%.

Abstract

In order to reduce the dependence on fossil fuels, acetone has emerged as an important platform chemical for various industrial applications. Acetone can be efficiently produced through the dehydrogenation of isopropanol, using metal-based catalysts with high activity and selectivity. The technology for this acetone production was simulated using Aspen HYSYS software, with operating parameters based on the reaction dynamics model for isopropanol dehydrogenation. This study evaluated the modification of the dehydrogenation process to improve energy efficiency by optimizing the heat transfer unit. The product heat leaving the reactor will be cooled in a heat exchanger and the heat is used to increase the heat from the mixer output, this is designed to utilize the process output energy, thus utilizing the heat exchanger as a cooler for the reactor output, thereby reducing additional energy consumption and improving the overall process sustainability. The modification includes increasing the acetone production yield and energy efficiency in the heat transfer unit to reduce energy consumption from 10.9296 MMBtu/h to 7.7431 MMBtu/h by utilizing the heat exchanger as a cooler for the reactor output back and at the same time a heater for the mixer output as a process optimization.

Abstract

The chemical industry in Indonesia continues to grow in terms of innovation and technology. One field that has experienced a significant increase is supporting materials, such as propylene glycol. The high demand for propylene glycol in its pure form makes modification of propylene glycol necessary. This modification is done by adjusting the molar ratio of hydrogen to glycerol by 5:1 which involves the process of hydrogenolysis. The physical condition (liquid or gas) of each compound was determined based on the vapor pressure equilibrium data of the pure compound, which was calculated using Hysys software with 2 property packages, namely the NRTL (Non-Random Two-Liquid) model and the uniquac model to determine the actual composition of each component. To obtain a high purity of propylene glycol, the process was modified with the addition of a mixer, recycle, splitter, and two distillation processes. The use of two distillations is used to obtain more optimal results.  In the Aspen HYSYS simulation, the reactor used for this process is a conversion reactor because the conversion reactor is the basis of the fluidized bed reactor. From the method that has been carried out, it is found that this modification is very effective in obtaining high propylene glycol purity. The percentage of propylene glycol in the final product increased from 73.5% to 90%. Copyright © 2024 by Authors, Published by Universitas Diponegoro and BCREC Publishing Group.

Abstract

The maleic anhydride production via benzene oxidation is a highly exothermic reaction which causes the product temperature will increase then it needs to be cooled down with a heat exchanger. The modification process is needed to improve the purity of the maleic anhydride process by adding stage of distillation. Maleic anhydride with lower purity from the first distillation is then distilled again in order to improve its purity. The process modification was simulated using Aspen HYSYS and the comparison of maleic anhydride purity between the basic and the modified process is shown in the form of table based on the material stream. The results obtained that the purity of maleic anhydride for both basic and modified process is about 62.64% and 97.72%. This shows that the modified process has higher maleic anhydride purity compared to the basic process as the purity is closer to 100%. Therefore, this modification increases the maleic anhydride purity of the production through benzene oxidation process.

Abstract

Ethylene is a feedstock that produces polyethene and other industrial chemicals such as ethylene oxide. The methanol-to-olefins process is a technology designed to transform methanol into light olefins like ethylene and propylene, which are crucial raw materials in the petrochemical industry. The first reaction involves the production of dimethyl ether and water from methanol. The second reaction consists of the conversion of dimethyl ether to ethylene and water. This paper will explain how to maximize ethylene production yield by modifying the methanol to olefin process. The process modification was carried out by adding a distillation tower. Based on process modifications increased the ethylene quantity from 21,070 tons/year to 179,400 tons/year. The case study results indicate an increasing yield of the product exiting.

Abstract

The hydrogenation process of nitrobenzene to aniline is one of the main methods in the chemical industry to produce aniline with high efficiency. This research focuses on optimizing this process through system modification, which includes implementing a recycling flow and adjusting operating conditions such as temperature and pressure. The simulation results show an increase in the conversion of nitrobenzene to aniline by 1.44% after modification, from 96.82% to 98.26%. Although these improvements may seem small, their impact is significant on an industrial scale, especially in reducing raw material waste and energy consumption, making it a more sustainable solution. This study provides valuable insights for improving the efficiency of aniline processes in the context of the global chemical industry.

Abstract

Methyl chloride, also known as chloromethane, is an important basic material in the global chemical industry. In 2022, the demand for methyl chloride in Indonesia was recorded at 103,748 tons per year. Based on projections, this figure is expected to increase to 134,696 tons per year by 2027. This study aims to investigate the design of methyl chloride plant by considering the efficiency in terms of energy and purity of yield by utilizing Aspen HYSYS V12 simulation tool in process integration. This research utilizes the iterative simulation method to compare the basic process simulation and the modified process simulation for methyl chloride production. The results show that the modified methyl chloride production process simulation has high energy efficiency as indicated by less energy requirements compared to the basic methyl chloride process. In addition, the simulation results of the modified methyl chloride production process produced methyl chloride reaching a high percentage of purity. In the basic process, the purity of methyl chloride reached 72.36% while the modified process showed an increase to 79.51%. It can be concluded that the simulation results of the modified process are more effective than the basic process in terms of energy requirements and purity product.
