Thermodynamic and Economic Analysis of Integrating Lignocellulosic Bioethanol Production in a Danish Combined Heat and Power Unit

C. Lythcke-Jørgensen, F. Haglind & L.R. Clausen
Integrating lignocellulosic bioethanol production with combined heat and power (CHP) production in polygeneration systems is considered an efficient and competitive way to produce a sustainable fuel for the transportation sector. This study assessed the energy economy of integrating lignocellulosic bioethanol production in the Danish CHP unit Avedøreværket 1. Numerical models of the plants were developed, and feasible integration solutions were identified and optimised using exergy analysis. Hour­wise production simulations were run over a reference year,...
