Unit 1- Introduction into Industrial Processes Flashcards
What are Industrial Processes?
SYSTEMATIC series of physical, chemical, or biological PROCESSES through which raw materials are converted into a product with GREATER VALUE
Give 3 Examples of Industrial Processes
Combustion, bleaching, freezing, drying, cutting, bending, filtration, scrubbing, RO, smelting
what resources do general industrial processes require to make an end product? Give an example.
Raw materials/feedstock, processes, and energy.

Is the end‑product the only product of the industrial processes? Example.
By products, physical waste, energy waste, pollution,
Name two sources of material resources for industrial processes
Raw material and feedstock
Name four categories of raw material resources.
Biomass, metal ores, non-metallic minerals (salt/gravel), fossil energy materials.
Series of processes used to remove impurities or unwanted substances out of a raw material
Refining
Two resources that require sustainability
Materials and energy
Name three sources of sustainable energy
Energy conservation,
Energy efficiency,
Energy recycling/recovery
Name three sources of sustainable energy
Energy conservation,
Energy efficiency,
Energy recycling/recovery
Energy conservation VS
Energy efficiency
Conservation is a change in behavior, Efficiency is a change in technology
In a “combined-cycle” natural gas power plant, a steam turbine uses the heat from the gas turbine to produce more electricity. Using a combined-cycle plant instead of a single-cycle, is an example of:
a) conservation of energy
b) recovery of energy
c) green energy
d) sustainable energy
B) Energy Recovery
What is a by-product? Give examples.
Accidental or secondary product produced during industrial processes:
- Black Liquor
- Fly Ash
- Manure
- sawdust
- asphalt
A by-product is a type of waste. (T/F)
T
By-product management
2 ways:
- limit their production
2. Identify their value
Industries must streamline their process to limit by-product creation. Also, by-products usually have
some value which should be identified. These practices could be achieved through:
a) industrial processes
b) resource conservation
c) energy recycling
d) by-product management
D) by-product management
What is waste?
Any substance which is disposed of or required to be disposed
What is carbon dioxide equivalent?
Used to measure global warming potential of each green house gas. CO2 eq of a gas over 100 years- the amount of CO2 that would have the same amount of GWP.
GWP
Global Warming Potential
GHG
Green House Gas
CO2 eq
Carbon Dioxide Equivalent
A higher CO2eq is better than a lower CO2eq. (T/F)
F. higher is worse. Methane is more potent than CO2
Which industry/sector generates the highest amount of solid waste in Canada?
a) oil sands
b) mining
c) municipal
d) livestock
a) oil sands
a > b > d > c
Water vapor is a very potent GHG. (T/F)
False. It has too short of a residence time in the atmosphere
3 examples of negative impacts of industrial processes (6 total)
- Depletion of resources
- pollution
- degrade land quality
- climate change
- haz waste
- Health problems
