(2024). Design of an industrial plant for production of monoethanolamine solution for CO2 capture in Kazakhstan. Nazarbayev University School of Engineering and Digital Sciences.https://nur.nu.edu.kz/handle/123456789/8262Kazakhstan's significant energy reserves, particularly in crude oil and coal, position it as a major global energy producer. However, the expansion of these natural resources has led to significant environmental degradation. To achieve carbon neutrality by 2060, this Capstone project focuses on designing an efficient and cost-effective production process for a monoethanolamine (MEA) solution, crucial for carbon capture. The project covers selecting the optimal manufacturing pathway, product specifications, reaction kinetics, catalyst choices, equipment design, plant location, and economic analysis. MEA will be produced by reacting ammonia with ethylene oxide using water as a catalyst, targeting an annual production of 68.5 kilotonnes of 30 wt% MEA solution. Validated through Aspen and Python-based simulations, the design includes detailed process flow diagrams and equipment specifications. The plant, to be located in the Pavlodar region, shows a net present value of USD 149.5 million with a 4.15-year payback period. Future enhancements could involve producing diethanolamine (DEA) and triethanolamine (TEA), ammonia recycling, and water use optimization.enAttribution-NonCommercial-NoDerivs 3.0 United StatesMonoethanolamineAspen PlusDiethanolamineTriethanolamineCarbon CaptureIndustrial PlantBachelor's thesis
