Biorrefinación sostenible del camarón: desarrollos desde la Ingeniería de Procesos Asistida por Computador.

Este libro presenta el diseño, simulación y evaluación sostenible de una biorrefinería integral de camarón para la producción de quitina, quitosano y astaxantina, con una capacidad de procesamiento de 4.110 t/año de camarones. Se registran las mayores eficiencias técnicas en la sección (iv) (91,92 %). Se obtuvo un VPN de 3,76 MM USD y una TIR de 23,6 %. Los componentes volátiles contribuyen a los impactos atmosféricos en la evaluación ambiental. La biorrefinería tuvo una eficiencia exergética de 25,61 % y las mayores pérdidas exergéticas en la etapa lavado de camarón; se obtuvo un ISI de 21 asociado a la desacetilación y al uso de acetona. El SASWROIM fue positivo alcanzando un puntaje de desempeño de 0,49, cercano al umbral deseable de 0,5.This book presents the design, simulation, and sustainable evaluation of an integral shrimp biorefinery for the production of chitin, chitosan, and astaxanthin, with a processing capacity of 4,110 t/year of shrimp. The highest technical efficiencies recorded in section (iv) (91.92%). A NPV of 3.76 MM USD and an IRR of 23.6% were obtain. Volatile components contribute to atmospheric impacts in the environmental assessment. The biorefinery had an exergetic efficiency of 25.61% and the highest exergetic losses in the shrimp washing stage; an ISI of 21 associated with deacetylation and the use of acetone was obtaining. The SASWROIM was positive, reaching a performance score of 0.49, close to the desired threshold of 0.5

Inherent Safety Analysis and Sustainability Evaluation of Chitosan Production from Shrimp Exoskeleton in Colombia

Waste valorization strategies are key to achieve more sustainable production within the shrimp industry. The crustacean exoskeletons can be potentially used to obtain value-added products such as chitosan. A comprehensive analysis including both safety and sustainability aspects of chitosan production from shrimp shells is presented in this study. The inherent safety analysis and sustainability evaluation was performed using the Inherent Safety Index (ISI) methodology and the Sustainable Weighted Return on Investment Metric (SWROIM), respectively. The process was designed for a processing capacity of 57,000 t/year. The return on investment (%ROI), potential environmental impact (PEI output), exergy efficiency, and the total inherent safety index (ITI) were used as indicators to evaluate process sustainability. The total inherent safety index was estimated at 25 indicating that the process is inherently unsafe. The main process risks were given by handling of flammable substances, reactivity, and inventory subindices. The overall sustainability evaluation showed a SWROIM of 36.33% indicating that the case study showed higher weighted performance compared to the return on investment metric of 18.08%
