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.

The ammonia production process is divided into four main stages: Feed Gas Pre-Treatment, Syngas Generation, Syngas Purification, and Ammonia Synthesis. The raw materials required for the ammonia production process include natural gas, steam, and air. To meet the increasing demand for ammonia, a production process with high efficiency is required in order to produce high conversion. One of the efforts to increase efficiency is through the addition of recycling, compressors, and TEE in the Aspen HYSYS simulation. With this increase in conversion, it is expected that the quantity of ammonia products produced will be greater, and the use of materials and energy will be more optimal. The method used to increase mass efficiency is by adding recycling, compressors, TEE, and adjusting the pressure in the separator. From this simulation, it can be concluded that our simulation shows an increase in mass efficiency compared to the simulation without the addition of compressors, recycle, and TEE in Aspen HYSYS. We can increase the mass conversion from 97% up to 99.09%. Net energy of the process can be reduced from 2.59e+8 to 1.64e+8 BTU/h.

The production of sorbitol by the hydrogenation process is carried out at high pressure so that a large amount of energy is required. The use of considerable energy in the production process supports the need for innovation for energy efficiency in the production of sorbitol from dextrose, which is expected to help increase sorbitol production so that it can meet market needs. The innovation carried out here is to change the operating conditions with the help of Ru/ASMA@AC catalyst so that the temperature required during the reaction is low. In addition, modifying the use of heat exchanger units so that the heat generated during operation is reused. These innovations were simulated using Aspen HYSYS software. The results of the simulation proved to be able to improve energy efficiency by reducing the performance of compressors and coolers used during production and saving considerable energy.

The current demand for methyl chloride in Indonesia exceeds production levels, making the design of a methyl chloride plant essential. This research focuses on improving methyl chloride production economically and operationally by exploring plant design using simulations that emphasize energy efficiency and high purity. The objective of this research is to develop a process design for producing methyl chloride from methanol and hydrogen chloride, aiming for energy efficiency, an environmentally friendly factory, and high-purity methyl chloride products. The research employed an iterative simulation method to compare the basic and modified processes for methyl chloride production. The process involved constructing a simulation model using Aspen HYSYS, analyzing the simulation results using Aspen Energy Analyzer V12, and iteratively adjusting process parameters until achieving the desired performance or results. The research findings indicate that the methyl chloride modification process exhibits a lower energy requirement compared to the methyl chloride base process. Moreover, the modification process demonstrates minimal carbon emissions, establishing it as a sustainable and environmentally friendly design. Additionally, the methyl chloride produced in the modification process achieves a higher percentage of purity. In the initial process, the methyl chloride purity stood at 98.17%, while in the modified process, it saw an elevation to 99.35%. Considering these three aspects, the modification process is conclusively more efficient than the basic process system.

The modification process is needed to improve the heat efficiency of the nitrobenzene hydrogenation process by utilizing the heat from reactor product. Heat transfer fluid is used as a medium of heat transfer for both heating and cooling, so that will create a looping heat transfer process. The looping system of heat transfer fluid receives heat from reactor product and then reuses the heat to reheat the recycled hydrogen and for other utilities, so additional energy for these processes is not required. The process modification was simulated using Aspen HYSYS and the comparison of heat efficiency 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 96,714,359.832 kJ/h and 9.869 kJ/h. This shows that the modified process has better energy efficiency compared to the basic process as the net-energy value is closer to zero. Therefore, this modification increases the heat efficiency of the aniline production through nitrobenzene hydrogenation process.
