Natural Gas and petroleum are an important role to society what is it used in
-Feedstock and fertilizer
-Source of fuel to heat homes
-To process materials in commercial and industrial applications
Natural gas is a mixture of
Hydrocarbon and non hydrocarbon gases (usually petroleum)
Exploration for oil and gas is conducted in areas known as
Sedimentary basins in earths crust
Basic elements of oil, natural gas and coal are?
Hydrogen and carbon; hence hydrocarbon
Natural gas is typically made of
95% methane
How do they find oil in the ground
-Aerial photography and magnetometer surveys the area
-Surface studies are conducted
-if hydrocarbons are present seismography
All natural gas production begins where and what happens to it
-Wellhead
-Has contains water so it must be treated or it will freeze
Water removal methods for gas involve
Absorption and adsorption
What is adsorption
Is the removal of water vapor by passing the vapor laden gas over a bed of granular SOLIDS that has an attraction for water
What is absorption
Is the removal of water vapor from a gas by bubbling the gas through a LIQUID desiccant
Oil absorption
Recovery
Rejection
Seperation
Why is sulphur removed when gas is burned
It produces acid rain and the gas corrosive action on the piping it’s getting transmitted through
Do pipeline companies own gas?
No
What’s the operating pressure for gas pipes
300 psi to 1500 psi
What transmits gas to the marketplace
Transmission pipelines
1 psi is = to how many WC”(water collum)
28”
What is put in gas to make it smell
Ethyl mercaptan(C2H5SH)
Where are the salt caves located in Canada
Fort Saskatchewan
What are salt caverns stored with
Natural gas at pressures of 4100 psi
Why and what temperature do they chill gas at
-258 and it takes up less space
How is manufactured gas produced
Passing steam over heated coal and contains hydrogen and carbon monoxide as the heat producing combustible
Liquid petroleum gas consists of
Methane
Ethane
Propane
Butane
Other hydrocarbons
Propane distribution from psi to water column is
5-10 psi and 11-14 inches of water column
What is the installation and storage code for propane
CAN/CSA 149.1 natural gas installation
CAN/CSA 149.2 storage and handling
