![]() ![]() Meanwhile, the second biorefinery configuration based on thermochemical routes presented an energy efficiency value of 70.89%. The energy results indicated that the overall energy efficiency calculated in the first scenario was only 9.15%. The obtained yields were the basis for energy and environmental analysis, in two different biorefinery scenarios: (i) production of bioethanol and biogas and (ii) production of syngas and electricity. This paper aims to evaluate experimentally a biorefinery producing energy vectors using coffee-cut stems (CCS) as feedstock. Samson boiler draft control upgrade#Nevertheless, energy and environmental comparisons are necessary to establish the best way to upgrade lignocellulosic biomass and set the requirements of these processes in different scenarios. Average cleaning efficiency of 61% which is comparable to that of sand bed filter and venturi scrubber cleaning systems reported in the literature was obtained for the cleaning system proposed in the current study.Įnergy-driven biorefineries can be designed considering biotechnological and thermochemical conversion pathways. Tar concentration in the raw gas sample was found to be higher compared to results for other biomass materials, which could be attributed to the higher volatile matter percentage of OPF. Average tar concentration of 4.928 g/Nm(3) and 1.923 g/Nm(3) was obtained for raw gas and cleaned gas samples, respectively. Elemental analysis of the char and solid tar samples was done using ultimate analysis machine, while the relative concentration of the different compounds in the liquid tar was determined making use of a liquid gas chromatography (GC) unit. The amount of char, ash, and solid tar produced from the gasification process was measured in order to account for the mass and carbon conversion efficiency. In this study, a tar sampling train custom built based on standard tar sampling protocols was used to quantify the gravimetric concentration of tar (g/Nm(3)) in syngas produced from downdraft gasification of OPF. The goal is to become a climate neutral company by 2030.One of the most challenging issues concerning the gasification of oil palm fronds (OPF) is the presence of tar and particulates formed during the process considering its high volatile matter content.
