Abstract

Dimethyl ether (DME) is widely recommended as an environmentally friendly aerosol and green refrigerant due to its low ozone depletion potential and lower global warming potential. Dimethyl ether is produced through the dehydration of methanol which has the potential to be an environmentally friendly alternative fuel. This research addresses the improvement of energy efficiency in dimethyl ether (DME) production through the modification of a heat transfer unit using Aspen HYSYS process simulation software. Dimethyl ether is an environmentally friendly chemical with low global warming potential, which is produced through methanol dehydration. This study focuses on the replacement of heaters and coolers. These modifications successfully improved energy efficiency by reducing net energy consumption from 4.867e+006 kJ/h to 3.268e+005 kJ/h. Despite the decrease in energy efficiency, the conversion rate remained the same at 99.7%.  This research shows that modification of the heat transfer system can support more energy-efficient and sustainable DME production.

Abstract

Methanol is a chemical product that is widely applied in the chemical industry. The methanol production process from carbon dioxide and hydrogen uses a hydrogenation process with a continuous stirred tank reactor (CSTR) under controlled thermodynamic and kinetic conditions. The process was modified by replacing the Gibbs reactor with a Continuous Stirred Tank Reactor (CSTR), adding temperature and pressure regulation, and a compressor. This study aims to increase the product yield obtained from the modification results and mass efficiency. Based on the experimental results, it can be concluded that the modified design is quite effective compared to before modification, because it increases the methanol product yield from 44.54% to 99.78%.

Abstract

Improving energy efficiency in the acetaldehyde production process is one of the strategic steps to optimize operations and support the sustainability of the chemical industry. This study aims to analyze the impact of adding a heat exchanger and increasing the mass rate of the feed absorber (water) on energy efficiency and hydrogen purity, as a by-product. Simulations were conducted with thermodynamic modeling-based software to compare the unmodified process system with the modified system. The addition of a heat exchanger was designed to minimize heat energy loss in the system by recycling heat energy from the process stream. Meanwhile, increasing the mass rate of the feed absorber aims to increase the capacity of the water absorber in separating impurity compounds, thereby producing hydrogen with higher purity. Simulation results show that the system modified with the heat exchanger successfully reduces the total energy demand by 1,695,040.81 kJ/h. In addition, increasing the mass rate of the absorber feed significantly improves the hydrogen purity to reach a more optimal level for advanced applications. In conclusion, the combination of adding a heat exchanger and adjusting the mass rate of the feed absorber not only improves energy efficiency, but also provides added value in the form of hydrogen with higher purity. This study provides practical guidance for the development of a more efficient and environmentally friendly acetaldehyde production technology.

Abstract

Vinyl chloride (C2H3Cl) is produced using ethylene (C2H4) and chlorine (Cl) as primary raw materials. In Indonesia, the demand for raw materials to produce plastics, especially PVC, continues to grow each year. The chosen method is the direct chlorination of ethylene, resulting in the production of 1,2-dichloroethane (EDC). The process involves two conversion reactors, the CRV-100 and CRV-101. The CRV-100 reactor produces EDC vapor and some EDC compounds. However, these compounds are often not recovered and are released into the atmosphere. To increase efficiency and yield the process by recycling maximize the reactants, the EDC feedstock is replenished by recycling the top product from the CRV-100 reactor. After cooling and separation, liquid EDC is recovered and reintroduced, increasing vinyl chloride production, resulting the purity has increased from 93.93% to 97.14%, the total mass production rises from 2232.8919 kg/h to 5477.0938 kg/h before optimization, representing a 145.29% yield, reflecting a significant improvement in production efficiency.

Abstract

Acetone is an essential ingredient in various industries whose demand continues to increase, thus requiring an efficient production method. This study aims to design an acetone production process by dehydrogenating isopropyl alcohol using Aspen HYSYS simulation and Aspen Energy Analyzer energy analysis. The simulation model was developed to enhance the purity of acetone products and improve energy efficiency by optimizing thermodynamic operating conditions. The dehydrogenation process was designed to produce acetone as the main product and hydrogen as a by-product. The basic process was then modified by integrating thermal energy and increasing the reactor operating temperature to improve energy efficiency and product purity. Simulations showed that the process modification resulted in an acetone purity of 99.76%, higher than the base process of 98.46%. In addition, energy savings in the modified process reached 40.89%, higher than the base process of 32.96%, with a reduction in carbon emissions of up to 40.88%. With these results, the modified process proved more efficient than the basic process and aligned with the research objectives.

Abstract

The acetylene hydrochlorination process is a highly exothermic reaction, causing the reactor temperature to rise, which then requires cooling through a heat exchanger. A modification of the process is necessary to enhance the heat efficiency of the acetylene hydrochlorination by utilizing the heat generated by the reactor. Heat transfer fluid serves as a medium for both heating and cooling, enabling a looping heat transfer process. The heat transfer fluid system absorbs heat from the reactor and subsequently reuses this heat to warm the reactor feed, eliminating the need for additional energy input. The process modification was modeled using Aspen HYSYS, and the heat efficiency between the basic and modified processes was compared using the net-energy formula. The results showed that the net-energy (NE) for the basic and modified processes were 38,811,930.515 kJ/h and 18,702.951 kJ/h, respectively. This indicates that the modified process offers better energy efficiency, as the net-energy value is closer to zero compared to basic process. Thus, this modification improves the heat efficiency of VCM production through the acetylene hydrochlorination process.

Abstract

Rising greenhouse gas emissions, particularly CO2, present significant environmental challenges. The goal of this study is to improve methanol synthesis using CO2 hydrogenation, with an emphasis on increasing purity. To accurately restrict temperature rises during CO2 compression, we did simulations with Aspen HYSYS V11 and a multistage compression approach.  Two notable alterations included the insertion of an absorber unit to improve methanol purity and the recycling of separator outputs. The results show that these process innovations save energy and raw resources while significantly improving methanol output. The findings demonstrate the viability of CO2 hydrogenation as an environmentally beneficial method of producing methanol, which reduces greenhouse gas emissions while still providing a viable chemical feedstock.

Abstract

Hydrogenation is chosen as a process to reduce CO2 in the air, based on its thermodynamic stability. One of the important things to increase the yield product is by using reactor. This study aims to compare two types of reactor, i.e. equilibrium reactor and conversion reactor. In this study, we made two types of processes as the representative for each type of reactor, by using the reaction and kinetic data from reference. As the result, we investigate the yield product result and the energy used. The number of energy used (in kW) in line to total yield product. For the equilibrium reactor, the yield product and energy used in kilowatt are lesser than the conversion reactor, and for conversion reactor is vice versa. Two of the results state that the higher total amount of energy used the higher total yield product. For the future study, this study could be one of the reference, or could be one of the future consideration for choosing exact reactor based on their needs.

Abstract

Vinyl chloride (VC) is a colorless stable gas produced through a complex process with many interactions in reaction and separation. This study aims to improve mass and energy efficiency in vinyl chloride production through process simulation with HYSYS V.11. The process was modified using a plugged flow reactor (PFR) with an Al2O3 catalyst and a simplified distillation column. The method involves recycling the liquid product from the distillation column back to the mixing unit as a feed. The results show that energy efficiency improves with the reduction of the reactor's heat flow requirement from 1.009×107 kJ/h, and to 4.689×106 kJ/h, and distillation of the 2.82×106 kJ/h to 1.368×106 kJ/h. Mass efficiency also increased, with vinyl chloride yields rising by 118%, from 2572 kg/h to 3045 kg/h. In conclusion, these process modifications have succeeded in reducing energy consumption and increasing production significantly, making the process more efficient and energy friendly. Further research is suggested to optimize the use of waste heat. Copyright © 2024 by Authors, Published by Universitas Diponegoro and BCREC Publishing Group.
