Biogas plants

Who can benefit from biogas plant? Agricultural companies: Pig farms; Cattle farms; Poultry farms; Crop production companies; Combined type companies. Food industry companies: Distillery and bioethanol plants; Brewery plants; Sugar mill; Meet processing factories; Veterinarian and sanitation plants; Starch and treacle plants; Yeast plants; Milk plants; Bakery plants; Chips and potato processing plants Juice and tinned food producers; Winery; Fish processing plants. Greenhouse farms. Biodisel producers. Waste recycling enterprises. Municipal waste water treatment plants. Biogas plant construction site Bioreactor inside In case you don’t have biological waste, you can grow energy crops for biogas production: corn, rosinweed, goat's rue, permanent grasses, algae and micro algae. Also biogas plant can be used as separate business on wastes recycling and energy services. In particular about biogas plant benefits Main benefits biogas, bio-fertilizer, Additional benefits electric an heat power (in case of additional module installation), methane as vehicle fuel or as natural gas substitute supply to grid (in case of additional module installation), investment savings (for new companies), ecology (in case of by products recycling) Biogas  By properties biogas is very similar to natural gas. Synonyms for biogas are such words as methane, sewage gas, marsh gas. Biogas caloric value if from 6000 to 9500 ccal/m3. Biogas can be: burned in boilers as natural gas; burned with the purpose of electric and heat power production; after its treatment up to methane it can be used as fuel for vehicles; Information Biogas - is gas with 50-70% of methane (CH4) and 50-30% of carbon dioxide (CO2) content. It is produced while anaerobic decomposition of organic matter and as is a product of bacteria metabolism. Anaerobic digestion - the process of organic matter decomposition without oxygen access   Substrate Biogas yield m3/t Cattle manure 60 Pig manure 65 Chicken dung 80-140 Corn silage 200-300 Fresh grass 200-350 Milk whey 50 Grain 500-600 Fruit pulp 70 Sugar beet pulp 50-60 Molasses 430 Sugar beet tops 200 Distillery slop (grain) 50-70 Distillery slop (molasses) 50 Brewer’s spent grains 150-180 Fat 1300 Fat from grease trap 250 Slaughter house waste 300 Root crop vegetables 100 Technical glycerin 500 Fish processing wastes 300 Cost price of biogas produced at biogas plant 20-30 Euros per 1000 m3.     Bio-fertilizer Biogas technology allows quick production of bio fertilizers which contain biologically active substances and microelements by means of anaerobic digestion. The main advantages of bio-fertilizer to be compared with conventional are it’s form, availability, nutrients balance and high level of organic matter humification. Organic matter is a powerful energy material for soil microorganisms, that is why after bio fertilizer application nitrogen-fixing and other microbiologcal processes are amplified. Above mentioned factor have positive effect to soil and its physical and mechanical properties and as a result after application of balanced bio fertilizers crop yields can increased up to 30-50%. Bio-fertilizer Electricity Buy burning 1 m3 of biogas in co-generation unit it is possible to produce 2,3 kWh of electric and 2,8 kWh of heat power. Biogas is burned without any treatment. Generator Information Co-generation unit - is equipment for combined production of heat and electricity. They use gas internal-combustion engine adapted to run on biogas. Heat power Heat power can be used for: buildings heating, technological purposes, , steam generation. Heat power produced by cooling the engine in co-generator. Biogas can combusted for heat production. As an option heat power can be used for refrigerator evaporators. Greenhouse Methane In order to use biogas as vehicle fuel or supply to gas grid it must be upgraded (CO2 removal) to biomentane with the help of biogas treatment system. After treatment produced gas is analog of natural gas (90-95 % of CH4). The only one difference is its source. Information СО2 (carbon dioxide) - colorless gas with acidulous smell, not toxic. It is the main source of carbon for plants. In liquid state it can be stored in balloons under high pressure 65-70 bar. In solid state it is usually known as dry ice. Main usage in greenhouses, vegetable storages, food industry (as preserving agent or for beverages), refrigeration plants, fire extinguishers.   Methane filling station Ecology Biogas plant is the most efficient cleaning system. Any other cleaning systems consume energy but not produce it. As all processes take place in oxygen free conditions (digesters completely sealed) it is odor free. Biogas plant allows to remove most part of contaminating organic substances that is why digested biomass has no bed smell. Biogas plant makes possible sanitary zone (distance from facility to living zone) reduction from 500 m to 150 m. For many companies ecological issues are of vital significance. In case biogas plant equipped with additional purification modules like membrane bioreactors, liquid digested biomass can be treated up to COD and BOD levels that are acceptable for open water surface or sewage system discharge. COD - chemical oxygen demand BOD - biological oxygen demand. Investments saving Without construction of biogas plant new enterprise anyway need need to have waste storage facilities or treatment systems. For example untreated manure storage is 2 times larger then storage of digested biomass after biogas plant. Manure in combination with water forms colloid compounds. Due to that water evaporates rather hardly and in case of precipitations it is accumulated. After biogas plant digested and mineralized water is not tended to form colloid compounds. More over! Biogas production is the best way to preserve methane atmospheric emission and global warming prevention.   Information ERU - Emission Reduction Unit equals to one ton of CO2 equivalent ( CO2 is used as a value unit to measure greenhouse gases, for example one cubic meter of methane equals 21 metric ton of CO2). In the international market ERU became a commodity for individuals, legal entities and countries. Countries that joined Kyoto Protocol can buy, sell or perform other operations in regards to the greenhouse gases emission rights.
