EGEE 101 Exam 3 terms; Questions & Answers
100% Correct
emission trading Correct answer-bringing new parts to less efficient countries to increase
efficiency. it is paid for and then claimed for credit of emission reduction.
biomass Correct answer-replanting forests to offset Carbon sinking. advantages:
increased employment, increased security of energy, increased fossil fuel lifetime, net carbon
dioxide neutral, less pollution.
methane Correct answer-contributes to increased concentration in atmosphere. capture
the methane for use instead of allowing leaks. livestock and landfills contribute the most
leakage.
sequestration Correct answer-locking away CO2 to keep it from entering the atmosphere.
storage of CO2: ocean, minerals, depleted oil and gas wells, brine fields, coal fields, carbon
sinks. power plants: air mixed with nitrogen... we want the oxygen but it's costly to separate.
sequestration: the ocean Correct answer-need more plankton to fertilize and trap CO2 as
they decay for carbon cycle. this is a carbon sink, there's more carbon in the ocean than in the
atmosphere.
3 processes of ocean sequestration Correct answer-1. carbon sink through fertilization 2.
inject CO2 into ocean to form hydrates 3. inject CO2 into bottom of ocean to form CO2
underwater lake.

100% Correct
sequestration: oil fields Correct answer-small holes in oil fields can be filled with CO2. if
the field is still producing the gas aids in extraction of crude through pressure. otherwise cap
the methane leaks.
sequestration: brine fields Correct answer-saline formations. estimated saline storage
capacity in the US is large and most existing CO2 point sources are within easy access to a saline
injection point. Sleipner West Heimdel gas reservoir of the Norwegian oil company Statoil is the
only commercial CO2 geological sequestration facility.
sequestration: coal Correct answer-large cracks and pores in coal allows permeability.
CO2 is attracted to the coal micropore and doesn't need much space to bounce around, it wants
to associate so we can fill more volume than we could with empty space. kicks out methane
too, sequester coal, collect methane. cost is slightly high and would increase the cost of
electricity.
conservation Correct answer-if we conserve, we use less, if we use less, we pollute less.
reduction Correct answer-achieved through economic depression, kind weather.
reducing N2O Correct answer-NOx consists of NO N2O and NO2. N2O is the greenhouse
gas of the three. solutions include: NOx removal (acid deposition), mitigation, prevention are
applicable to N2O.
