Methane yield of any digestible organic material is of prime importance during projects development, and feasibility and economic analysis. What is the percent error? A sample of maize has elemental composition (weightasapercentageofVS)of0.5,0.08,0.35, 0.06 and 0.01 of carbon, hydrogen, oxygen, nitrogen, and sulphur respectively. Kinetics of the co-digestion could be obtained with Gompertz and First order models. In equation form: grams product = grams reactant x (1 mol reactant/molar mass of reactant) x (mole ratio product/reactant) x (molar mass of product/1 mol product) The theoretical yield of our reaction is calculated using: molar mass of H 2 gas = 2 grams. Solution for In the lab, I actually produced 23.5 g of methane when my theoretical yield was supposed to be 21.1g of methane. in Civil Engineering and M.Sc. Noori M.

Gompertz model determine productivities and kinetics within the 7th day of experiment. A question faces any biogas developer is how much methane will be produced upon digesting a specific substrate. Besides there are some models capable not only of reproducing the methane curve behavior, but also of predicting final methane productions from the first days of experimentation. Differences exist between the TheoMY and ExpMY because of the assumptions of the Buswell and Mueller’s equation and variation of the experimental conditions. Theoretical methane production generated by the co-digestion of organic fraction municipal solid waste and biological sludge. Methane yield of any digestible organic material is of prime importance during projects development, and feasibility and economic analysis. He worked at the Dairy and Swine Research and Development Centre, Agriculture and Agrifood Canada, where he investigated livestock and agricultural waste management. He served on organizing, program or scientific committees for more than 18 international conferences. He is specialized in bioprocesses and biotechnologies converting organic waste into biofuel and bioenergy using wet and dry anaerobic digestion. By continuing you agree to the use of cookies. He received B.Sc. By controlling conditions such as … Prediction methodologies give an indication of maximum methane productivity. Substrate Gas yield (l/kg VS *) Methane content (%) Pig manure: 340-550 65-70 Cow manure 90-310 65 Poultry droppings 310-620 60 Horse manure COD removal efficiency is around 98% and by calculation, around 40 g/L COD removed (soluble COD value). This equation gives the theoretical value of methane at laboratory conditions: (2) BMP thCOD = n CH 4 R T pVS added where BMP thCOD is the theoretical production at laboratory conditions, R is the gas constant (R = 0.082 atm L/mol K), T is the temperature of the glass bottle(308 K), p is the atmospheric pressure (1 atm), VS added (g) are the volatile solids of the substrate and n CH 4 is the … The purpose of this poster is to create a data-bank list of the methane yields of various organic feedstock based on their predicted theoretical methane yield (TheoMY) by Buswell and Mueller’s equation (BM Eq.) Substrate / Gas Yield / Methane Content . The theoretical biochemical methane potential (TBMP) of the material is calculated from : TBMP (m l C H 4 g V S − 1) = 22.4 × (a 2 + b 8 − c 4 − 3 d 8 − e 4) 12.017 a + 1.0079 b + 15.999 c + 14.0067 d + 32.065 e
