Natural gas from the wells for use in a gas processing plant is known as:

1) Sour gas

2) Feedstock

3) Hydrocarbon

4) Emulsion

5) Well site supply

Back 1

Feedstock

Front 2

The purpose of stabilization in natural gas treatment plants is to:

1) Stabilize the liquid and gas in the inlet separator

2) Flash off the gases at high pressure from the liquids

3) Stabilize the gas from the contactor

4) Prevent water from evaporating in the gas stream

5) Flash off the gases at low pressure from the liquid hydrocarbons

Back 2

Flash off the gases at low pressure from the liquid hydrocarbons

Front 3

The purpose of an inlet separator in a natural gas plant is to remove the:

1) Hydrogen sulphide from the gas

2) Solids from the liquids

3) Un-dissolved gases from the hydrocarbons

4) Liquids from the gas

5) Carbon monoxide from the liquids

Back 3

Liquids from the gas

Front 4

Some trees such as the pines, Douglas fir, tamarack, and some others cannot be successfully made into pulp by one of the following processes:

1) Sulphate

2) Alkaline

3) Sulphite

4) Acid

5) Cooking

Back 4

Sulphite

Front 5

The purpose of the absorber in a natural gas plant is to:

1) Remove condensate from the gas

2) Absorb carbon dioxide from the gas stream

3) Remove hydrogen sulphide and carbon dioxide from the gas

4) Scrub the gas from amine

5) Absorb all the hydrocarbons from the gas

Back 5

Remove hydrogen sulphide and carbon dioxide from the gas
