1 DESIGN OF BIOGAS PLANT 1.1 Introduction: Bio-gas Project, LGED Biogas can be obtained from any organic materials after anaerobic fermentation by three main phases. 1.2 Mechanism of biogas fermentation: A) Groups of Biogas microbes- Biogas microbes (Bacteria) Non methane producing Methane producing Fermentative Bacteria Hydrogen-producing acetogenic bacteria B) Groups of microbes involved in the 3 stages of biogas fermentation- 1 st stage: Fermentative bacteria- Hydrolyze & Ferments Organic substance Cellulose decomposing bacteria Saccharides Protein decomposing bacteria Amino acids Fat decomposing bacteria Fatty acids Volatile acids, H 2 & CO 2 Page-1
2 2nd Stage: Hydrogen producing acetogenic bacteria- Decompose the substances produced in 1 st stage Acetic acid, H 2, CO 2 3 rd Stage: Methane producing bacteria- Convert the substances produced in 1 st & 2 nd stage CH 4 & CO Design perameter: A) Selection of materials : B) Total solid (TS) contains calculations of organic materials Organic materials- Solid part : Total solid contained in a certain amount of materials is usually used as the material unit to indicate the biogas- producing rate of the materials. Most favourable TS value desired is 08% Liquid part : As per Annexure-I C) Favourable temperature, P H value & C/N ratio for good fermentation- Temperature: Mesophilic; 20 o c to 35 o c ( Annexure-II). P H value : Neutral P H and ranges 6.8 to 7.2 C/N ration : Ranges from 20:1 to 30:1 ( Annexure- VI ) Page-2
3 Kinds D) Table showing discharge per day, TS value of fresh discharge and water to be added to make favorable TS condition- Body weight Discharge per day TS value of fresh discharge (% by wt.) Water to be added with fresh discharge to make the TS value 8% Human Cow Chicken Pig E) Hydraulic retention time ( HRT)- For Mesophilic digestion where temp. varies from 20 o c to 35 o C and HRT is greater than 20 days. 1.4 Relationship between temperature, HRT & TS value of 8% : 30 O 25 O 15 O TS ±8% Temp. ( o c) HRT (days) Page-3
4 1.5 Cross-section of a digester: Vgs Vc V H V f V S a) Volume of gas collecting chamber = Vc b) Volume of gas storage chamber = Vgs c) Volume of fermentation chamber = V f d) Volume of hydraulic chamber = V H e) Volume of sludge layer = Vs Total volume of digester V =Vc+Vgs+V f +Vs 1.6 Geometrical dimensions of the cylindrical shaped biogas digester body: V 1 S 1 f 1 V 3 R 1 V 2 R 2 H S 2 R D f 2 Page-4
5 1.7 Assumptions: For volume Vc 5% V Vs 15% V Vgs + V f = 80% V Vgs = V H Vgs = 0.5 ( Vgs + V f + Vs ) K Where K = Gas production rate per m 3 digester volume per day. For Bangladesh K = 0.4 m 3 /m 3 d. For geometrical dimensions D= X V 1/3 V 1 = D 3 V 2 = D 3 V 3 = D 3 R 1 = D R 2 = D f 1 = D/5 f 2 = D/8 S 1 = D 2 S 2 = D Volume calculation of digester and hydraulic chamber: A)Volume calculation of digester chamber- Given : 6 cows of body weight 200 Kg each. Temp. = 30 O C (average) Sol n : Let HRT = 40 days ( for temp. 30 O C ) Total discharge = 10 kg X 6 = 60 Kg/day TS of fresh discharge = 60 kg X 0.16 = 9.6 Kg. In 8% concentration of TS ( To make favourable condition ) 8 Kg. Solid = 100 Kg. Influnt 1 Kg. Solid = 100 / 8 Kg influent 9.6 Kg Solid = 100 x 9.6/ 8 = 120 Kg. Influent. Total influent required = 120 Kg. Water to be added to make the discharge 8% concentration of TS =120 Kg - 60 Kg. = 60 Kg. Working volume of digester = Vgs + V f Page-5
6 Vgs + Vf = Q.HRT = 120 Kg/day X 40 days = 4800 Kg. ( 1000 Kg = 1 m 3 ) = 4.8 m 3. From geometrical assumptions: Vgs + V f = 0.80 V Or V= 4.8/0.8 = 6.0 m 3. (Putting value Vgs + Vf = 4.8 m 3 ) & D = V 1/3 = m 2.40 m. Again D H V3 = 4 (Putting V 3 =0.3142D 3 ) D Or, H = = 0. 96m D Say H = 1.00m Now we find from assumption as we know the value of 'D' & 'H' f 1 = D/5 = 2.40 /5 = m f 2 = D/8 = 0.30m R 1 = D = 1.74 m R 2 = D = 2.55 m V 1 = D 3 = m 3 Vc = 0.05V = 0.3 m 3 Now the dimension of digester chamber is kown & drawn below- V 1 =1.143m 3 V 2 V3 R 1 = 1740mm R 2 = 2550mm f 1 =480mm H =1000mm f 2 =300mm D = 2400mm B) Volume calculation of hydraulic chamber- Page-6
7 Vc h 3 h 3 V H h = h 3 +f 1 +H 1 f 1 Vgs h 2 = 800mm H 1 H 1 From assumptions: Vc = 0.05 V = 0.3 m 3 Vgs = 0.50 x (Vgs + V f + Vs) x K ( Where K = Gas production rate per m 3 digeste vol./day ) = 0.5 x 5.7x 0.4 =1.14 m (A) Again, Vgs = 50% of daily gas yield = 0.5 x TS x gas producing rate per Kg TS = 0.5 x ( 60 kg x 0.16 ) x 0.28 m 3 /kg TS ( See Annex- III ) = m (B) From A & B let Vgs = m 3. Vc + Vgs = 0.3 m m 3 = m 3 Again V 1 = [{(Vc + Vgs) - {π D 2 H 1 }/4 ] = [ {3.14 x (2.4) 2 x H 1 }/4] Or, H 1 = 0.110m We have fixed h = 800 mm water volume ( I mm = 10 N/ m 2 ) h = h 3 + f 1 + H 1 Or, h 3 = 0.210m. Again we know that Vgs = V H Or, m 3 = 3.14 x (D H ) 2 x h 3 /4 Or, D H = 2.85m Page-7
8 Now we know the dimension of hydraulic chamber. Moreover keeping h = 800 mm, we can choose or re-arrange the dimension considering availability of site and construction suitability. For most suitable dimensions we can select the drawing of Annexure- IX for 60 Kg cow dung per day as raw material. Note: For ready reference 4 family type Biogas plant's drawing is shown(standared dimension's) in Annexure-VIII, Annexure-IX, Annexure-X & Annexure-X1 where 40 Kg, 60Kg, 80Kg and 100Kg cow dung is considered as raw marterial per day respectively. If bigger size plant is required,it can be designed keeping all safety considerations in design and construction.
