Paddy fields account for around 20% of human-related emissions of methane -- a potent greenhouse gas. This released Methane gas can be used for human consumption from the above method.
3. Paddy fields account for around 20% of human-
related emissions of methane -- a potent greenhouse
gas. Farmers normally flood rice fields throughout the
growing season, meaning
that methane is produced by microbes underwater as
they help to decay any flooded organic matter. Thus
making methane harmful for the crops. We can use
this methane from the paddy fields for other
purposes
4. We will use small pipes with semi permeable
membranes which would have activated
carbons for adsorption of methane.
activated carbon, also called activated charcoal, is a
form of carbon processed to have small, low-volume
pores that increase the surface area available
for adsorption or chemical reactions
5. This collected methane will be stored in a container for further uses.
Benefits of methane :
• it can be burned to produce electricity
• used as a fuel for ovens, homes, water heaters, kilns, automobiles, turbines, and
other things
• methane produces less carbon dioxide for each unit of heat released.
• methane's heat of combustion is lower than any other hydrocarbon but the ratio of
the heat of combustion (891 kJ/mol) to the molecular mass (16.0 g/mol, of which
12.0 g/mol is carbon) shows that methane, being the simplest hydrocarbon, produces
more heat per mass unit (55.7 kJ/g) than other complex hydrocarbons
• Methane in the form of compressed natural gas is used as a vehicle fuel and is
claimed to be more environmentally friendly than other fossil fuels such
as gasoline/petrol and diesel
