Abstract:
Paper industry is an “energy intensive” sector, therefore an increasing fraction of energy requirements is currently fulfilled by self-production, the most common solution being represented by gas-fired CHP plants. Moreover, the growing use of recovered paper and board as the raw material requires rational solutions for the management of the refuse originated by the mechanical separation of gross impurities from the usable fibre. A preliminary assessment of a novel solution for biomass and waste valorisation in paper mills, based upon the thermal gasification process and the subsequent co-firing of producer and natural gas in a gas turbine was performed. Preliminary waste characterisation shows that it has a remarkable LHV of 27.5 MJ/kg, thus confirming its potential use as a fuel for a thermo-chemical process. According to pilot tests results, a fuel gas with an excellent LHV of nearly 30 MJ/Nm³ can be produced via steam gasification. Furthermore thanks to producer gas high light hydrocarbons fraction, gas turbine performance should not significantly deteriorate due to the co-firing approach. The proposed solution, for the investigated case study, allows to save around 20% of natural gas consumption with an estimated payback period for the investment of only about 8 years.
