Production of methanol from a mixture of torrefied biomass and coal

Comparisons between energy carriers' productions for exploiting renewable energy sources

“…The equipment costs were taken from the literature [17,32,37,38]. The costs calibrated in regard to the figure for the year 2013 using the CEPCI index (Chemical Engineering Plant Cost Index) [39] and then the capacity was standardised to a 600 MW electricity plant using the following equation C ¼ n e C 0 ½S=ðn,S 0 Þ f , where C is the cost of a process unit, n the number of equally-sized units, C 0 the cost of a reference unit, S the capacity of a process unit, S 0 the capacity of a reference process unit, e the cost scaling exponent for different numbers of equallysized units (fixed to 0.9), and f the cost-scaling factor (fixed to 0.67) [25].…”

“…Afterwards the syngas was cooled to 300 C before it entered the desulphurisation unit. As the amount of sulphur is very low in the torrefied biomass [25], ZnO sorbent was selected for the removal of sulphur components. In the next stage, the clean synthesis gas was further cooled in F1, whilst removing the condensed water.…”

100% sustainable energy

“…Paper [78] investigated the influence of adding torrefied biomass within an entrained flow coal gasifier for the production of methanol. Computer simulations of gasifying a mixture of torrefied biomass and coal within an entrained flow gasifier, synthesis gas purification, and methanol synthesis were carried out using the Aspen plus program package.…”

Multi-objective optimization of a sugarcane biorefinery for integrated ethanol and methanol production

“…Biomass pre-treatment: To meet the processing requirements of the gasifier, biomass must be pre-treated [32]. In all evaluated cases, biomass is dried using an air dryer down to 15% w/w of moisture content before gasification.…”
