20.500.12556/DKUM-92817 Improving electricity generation during the product reaction loop and the use of exhaust gas for co-product production using polyethylene waste and flue gas or wood More energy-efficient industries could reduce the problems of pollution, global warming, energy security, and fossil fuel depletion, including processing waste into raw materials and more efficient energy cogeneration. This research project considers the novelties of the upgraded electricity cogeneration technique, including one open gas turbine during the high-pressure product reaction loop and a second turbine during the exhaust gas for co-product production with only one compressor. The upgraded electricity cogeneration was carried out in two steps and based on the productive use of otherwise useless polyethylene waste, flue gas, and wood. The first step can simulate the simulation model from the existing product production with well-known technology and process units using the Aspen Plus® simulator. The maximum available electricity cogeneration can previously be determined from the thermodynamics of the products and co-products, and an existing energy unit’s characteristic capacity. In the second step, conventional natural gas can be replaced with waste as the raw materials by using the same simulated model from the first step, including electricity cogeneration using the gas turbines during the high-pressure reaction loop, and the exhaust gas as the co-product with only one compressor. This research on electricity generation is based on processes that include the pressure drop during the product reaction loop. This approach is illustrated using an existing methanol production process, using wastes as sustainable raw materials, including electricity cogeneration during the reaction loop and exhaust gas, generating a possible increase in annual profit of 7.28 MEUR/a. waste recovery cogeneration exothermic reactor gas turbine exhaust gas combined compressor ponovna uporaba odpadkov kogeneracija plinske turbine kombinirani kompresorji true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/processes © 2022 by the author Članek v reviji 2025-05-15 08:35:58 2025-05-15 08:35:59 2025-05-16 03:10:53 0000-00-00 00:00:00 2022 0 0 12 str. iss. 11 Vol. 10 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-09-30 2022-10-28 2022-11-01 66.02 128190723 10.3390/pr10112251 2227-9717 processes-10-02251.pdf processes-10-02251.pdf 1 B22CB1720F6A0D2CDB3762F5905A47A5 53ad1fc90068478e0ac0c14af75c9de9e74b4814866726f43e170c786fccaacf 1fe74644-3157-11f0-832c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=191027 https://www.mdpi.com/2227-9717/10/11/2251 0 28aec085-3157-11f0-832c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=191028 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
