| Opis: | 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. |
