“…The cost of the main reactors (steam reformer and methanol synthesis reactor) were estimated from actual commercial quotations and costs present in literature [1,70]. These costs were updated to present value using the widely used chemical engineering plant cost index (CEPCI) [71]. In addition, the main equipment costs were adjusted for the required capacity to estimate the present values of the equipment as shown in Eq.…”

Due to the large amount of crude glycerol produced as a by-product by the biodiesel industry, alternative technologies for converting glycerol to value-added fuels such as syngas have been proposed. By employing four main processes, the syngas could further be used to produce methanol. The first process is steam reforming (STR) where the crude glycerol is converted into syngas. The next step is a three-unit pressure swing adsorption (PSA) system which is employed to condition the syngas into the required stoichiometric ratio. The final two process are the methanol synthesis and methanol purification processes. The effects of STR temperature, steam-to-glycerol ratio (SGR), methanol synthesis temperature and pressure were all investigated. The results obtained shows that 0.29 kgMeOH/kgCG can be obtained through this process at STR of 650 ℃, SGR of 9, and methanol synthesis temperature and pressure of 250 ℃ and 80 bar respectively. In addition, a methanol production plant capacity of 6.8 tonnes/hr of crude glycerol feed for a 20-year plant life was investigated. The result from the economic analysis carried out shows that production of methanol from glycerol is economically feasible with net present value (NPV), return on investment, (ROI), discounted payback period (DPBP) and net production cost (NPC) of $74.2 million, 17%, 4.59 years, and 85₵/kgMeOH respectively. The sensitivity analysis results show that the revenue from sales of methanol and byproducts (hydrogen and methane), the manufacturing cost, the cost of raw materials, as well as fixed capital investment (FCI) were the most sensitive economic parameters.

“…The difficulties of landfilling this waste lead to the necessity of utilizing it. Thermal degradation approaches like pyrolysis and gasification are fast and require high-energy-demanding and expensive catalysts, and in gasification, they generate highly toxic compounds [22,23]. Lignocellulose is easier to decompose compared to synthetic polymers or tires [24].…”

The influence of microaeration, pH, and substrate during dark fermentation of sour cabbage, gelatin, and wheat straw was investigated, and the results of dark fermentation of these three substrates and their mixtures are presented in this research. The fermentation of cabbage, gelatin, and wheat straw was investigated under varying pH and aeration conditions. We investigated concentrations of volatile suspended solids (VSS) of 20 g VSS/L of a substrate at a stable pH of 6.0 and a not aligned pH value. Sour cabbage resulted in the highest volume of hydrogen for 450 mL/g VSS with a pH of 6.0. The mixing of substrates caused lower hydrogen production than sour cabbage or wheat straw alone.

Waste tyre gasification offers a variety of benefits amongst which include the production of syngas—an alternate source of energy generation and activated carbon (AC)—a very good adsorbent used in industrial purification processes. In this study, a conceptual design of an industrial production plant design process and economic analysis of waste tyre gasification process for the co-production of syngas and AC were evaluated. Three reactor configurations namely: fluidized bed, fixed bed, and rotary kiln gasifiers were investigated in the design process. The design process put into consideration the total plant cost (TPC), total capital investment (TCI), the cost of raw materials, waste disposal cost, amongst other vital economic parameters. The fixed bed reactor has the highest syngas and AC production with 10,130 kg/h and 214.61 kg/h, respectively when compared to the other gasifiers. The minimum selling price (MSP) of syngas was set as 1$/kg and AC was set at $2/kg. The result obtained shows that the fixed bed production route was the most economical amongst the three reactor configurations considered. The fixed bed route has a net present value (NPV) of 435 M$, return on investment (ROI) of 56%, internal rate of return (IRR) of 54%, and a payback period (PBP) of 4.86 years. Finally, a sensitivity analysis considering a $$\pm $$ ± 20% variation in key economic parameters such as the syngas MSP, inflation rate, interest rate, tax rate, operating expenditure (OPEX), and capital expenditure (CAPEX) amongst others was investigated. The analysis shows that the syngas MSP, OPEX, inflation rate, and CAPEX have the most effect on the NPV of the waste tyre gasification process.
