Diethanolamine (DEA) solutions are used in refineries to sweeten gas. DEA is responsible for absorbing H₂S from sour gas. In an Amine Regeneration Unit (ARU), the rich amine with H₂S is regenerated. A refining column in the Middle East started commercial production in 2020. Using Aspen HYSYS V.11, an amine regeneration unit in the refinery that supplies lean amine to the delayed cooker unit for gas sweetening was simulated, and an exergy study was performed on various equipment. Exergy is destroyed in an irreversible process, while energy is converted from one type to another. The sum of the physical and chemical exergy is the total exergy. The chemical exergy was calculated using a series of equations embedded in Excel, while the physical exergy was calculated using HYSYS. The DEA concentration used is 25 wt%. Each equipment's exergy destruction rates, destruction efficiency, and percentage share of destruction were determined. The regenerator had the highest destruction rate of 2144.11 kW and an 80.21 percent share of total destruction. With a value of 326.00 kW and a percentage share of 12.20 percent of total destruction, the air cooler has the second-highest exergy rate. Exergy has a 99.70 percent overall efficiency. Due to system losses, the DEA concentration fell from 25% to 20% of the design value. The regenerator had the highest destruction rate of 2616.74 kW followed by the air cooler with a value of 294.61 kW. In DEA 20%, an exergy analysis was carried out. Exergy research showed the same percentage share distribution for equipment at a concentration of 20 DEA wt. percent. To find related equipment relationships, the results of the unit's exergy analysis were compared to those of another ARU exergy study at the same refinery plant. The regenerators were found to have the highest exergy destruction of the two units with a percentage share of the overall destruction reaching 80% followed by the air coolers with values reaching 9%.

二乙醇胺 (DEA) 溶液在炼油厂中用于使气体脱硫。DEA 负责从酸性气体中吸收 H ₂ S。在胺再生单元 (ARU) 中，富含 H _{2 的}胺S 重生。中东某炼油塔于 2020 年开始商业化生产。 使用 Aspen HYSYS V.11 模拟炼油厂的胺再生装置，该装置向延迟蒸煮装置提供贫胺进行气体脱硫，并对各种设备。火用在不可逆转的过程中被破坏，而能量从一种类型转换为另一种类型。物理和化学火用的总和就是总火用。化学火用使用 Excel 中嵌入的一系列方程计算，而物理火用使用 HYSYS 计算。使用的 DEA 浓度为 25 重量％。确定了每种设备的火用破坏率、破坏效率和破坏百分比。再生器的销毁率最高，为 2144.11 千瓦，占总销毁量的 80.21%。空气冷却器的功率值为 326.00 kW，占总破坏量的 12.20%，火用率排名第二。Exergy 的整体效率为 99.70%。由于系统损失，DEA 浓度从设计值的 25% 下降到 20%。再生器的破坏率最高，为 2616.74 kW，其次是空气冷却器，为 294.61 kW。在 DEA 20% 中，进行了火用分析。火用研究表明，浓度为 20 重量份 DEA 的设备具有相同的百分比份额分布。百分。查找相关设备关系，将该装置的火用分析结果与同一炼油厂的另一项 ARU 火用研究的结果进行了比较。发现再生器在两个单元中具有最高的火用破坏，占总破坏的百分比达到 80%，其次是空气冷却器，其值达到 9%。
