When a factor of production is not doing any job we say it is unemployed. In this project we are concentrating mainly on the Economic effect of unemployment in Nigeria Economy. In particular Emphasis on Labour which is the most important and active factor of production which simple means, that without Labour all other factors will not be put into practice.
The fractional volume of water vapor is a function of biogas temperature; correction of measured gas volume for water vapour content and thermal expansion is easily done via simple mathematics  which yields the standardized volume of dry biogas.
In some cases, biogas contains siloxanes. They are formed from the anaerobic decomposition of materials commonly found in soaps and detergents.
During combustion of biogas containing siloxanes, silicon is released and can combine with free oxygen or other elements in the combustion gas. Deposits are formed containing mostly silica SiO 2 or silicates Si xO y and can contain calciumsulfurzincphosphorus.
Such white mineral deposits accumulate to a surface thickness of several millimeters and must be removed by chemical or mechanical means. Practical and cost-effective technologies to remove siloxanes and other biogas contaminants are available. Benefits of manure derived biogas[ edit ] High levels of methane are produced when manure is stored under anaerobic conditions.
During storage and when manure has been applied to the land, nitrous oxide is also produced as a byproduct of the denitrification process. Nitrous oxide N2O is times more aggressive as a greenhouse gas than carbon dioxide  and methane 25 times more than carbon dioxide.
In fact, one cow can produce enough manure in one day to generate 3 kiloWatt hours of electricity; only 2. If compressed, it can replace compressed natural gas for use in vehicles, where it can fuel an internal combustion engine or fuel cells and is a much more effective displacer of carbon dioxide than the normal use in on-site CHP plants.
The corrosive nature of H 2S alone is enough to destroy the mechanisms.
If the local gas network allows, the producer of the biogas may use their distribution networks. Gas must be very clean to reach pipeline quality and must be of the correct composition for the distribution network to accept.
Carbon dioxidewaterhydrogen sulfideand particulates must be removed if present. Biogas gas-grid injection[ edit ] Gas-grid injection is the injection of biogas into the methane grid natural gas grid.
Until the breakthrough of micro combined heat and power two-thirds of all the energy produced by biogas power plants was lost as heat. Using the grid to transport the gas to customers, the energy can be used for on-site generation resulting in a reduction of losses in the transportation of energy.
During the cleaning process trace components harmful to the gas grid and the final users are removed. Compressed biogas is becoming widely used in SwedenSwitzerlandand Germany. Ina British documentary film titled Sweet as a Nut detailed the biogas production process from pig manure and showed how it fueled a custom-adapted combustion engine.
The mist or fog is predominately water vapor that condenses on the sides of pipes or stacks throughout the gas flow.
Biogas environments include wastewater digesters, landfills, and animal feeding operations covered livestock lagoons. Ultrasonic flow meters are one of the few devices capable of measuring in a biogas atmosphere.
Most of thermal flow meters are unable to provide reliable data because the moisture causes steady high flow readings and continuous flow spiking, although there are single-point insertion thermal mass flow meters capable of accurately monitoring biogas flows with minimal pressure drop.
They can handle moisture variations that occur in the flow stream because of daily and seasonal temperature fluctuations, and account for the moisture in the flow stream to produce a dry gas value.
European Union[ edit ] The European Union has legislation regarding waste management and landfill sites called the Landfill Directive. Countries such as the United Kingdom and Germany now have legislation in force that provides farmers with long-term revenue and energy security.
If the estimated NMOC emissions exceeds 50 tonnes per year, the landfill owner is required to collect the gas and treat it to remove the entrained NMOCs.Find here a detailed pig farming business plan sample checklist for your ready reference.
Starting piggery is a very much profitable livestock business. Among the various livestock species, piggery is the most potent source for meat production and pigs are more efficient feed converters after the broiler.
