A bulk waste tank at the District must be set up to receive unused bulk material left in bulk tanks. The collection tank of the dust collector is used as a junk tank at many Districts. This bulk tank must be separated from the rest of the bulk system to reduce the possibility of contaminating other bulk materials with the returned cement systems.
In a pressure/vacuum plant the use of the weigh batch blender is required to remove waste product from the waste collection tank. Product is drawn into the WBB by means of vacuum and then transferred directly to the bulk transport for waste removal through an isolated valve primarily intended for this purpose. This valve remains locked at all other times.

As compressed air flows though bulk material, it tends to compact the particles.
True False
The amount of material carried by air depends on which of the following factors? Select all the correct answers. atmospheric pressure
amount of compressed air geographical location
pressure inside the holding tank size of piping between tanks pressure inside the receiving tank
When conveying bulk material using Unsteady Dense Plug Flow, the delivery rate is controlled at the discharge end of the transport line. True
False
Which of the following is true about the fill line on a pressure tank?
The opening of the line will be at the bottom of the tank.
The opening of the line will be at the top of the tank.
The line is often constructed as a dip tube.
The line must be positioned in a specific place on the outside of the tank.
On most Schlumberger pressure tanks, the pressure relief valves are designed to relieve at what pressure?
35 psi 30 psi 20 psi 15 psi
The porous media used as aeration devices in pressure tanks are
commonly made of high-density plastic. True
False

who owns the tank
type of metal used for construction welding procedures
testing procedures
utilization of approved welders and inspectors
Match each pressure vessel component with its description. Vacuum systems:

Which of the following statements are true for both surge cans and gravity silos? Select all the correct answers. They separate bulk material transport
from bulk material supply metering. They allow air used to transport bulk
material to escape.
They provide a buffer when switching from one P-tank to another.
They can be used as storage tanks for bulk material on location.
They are considered “code” tanks. The pressurized surge cans used by
Schlumberger are equipped with a side discharge.
True False
Which of the following components on a reciprocating compressor is responsible for maintaining the desired pressure?
pop-off after-cooler bleeder valve unloader
How is the ft3/min discharge of a rotary
axial compressor regulated? by varying the rpm at which the
compressor turns
by throttling the intake valve by throttling the exhaust valve by an adjustable relief valve
Match each type of compressor with its principle of operation.
Air is forced into a smaller diameter on the discharge end.
a. reciprocating
Acts like a blower. b. rotary axial Works like a two-
cycle engine. c. vane type
Which of the following is a risk of having a dirty air filter on a reciprocating
compressor?
Dirt could cause vanes to disintegrate. The four-way valve could be clogged. Oil could be carried to the pads in the
bulk cement tank.
The after-coolers could overheat. Match each moisture removal device
with its principle of operation.
Desiccant cartridge a. after-cooler Centrifugal force b. dryer Condensation through
thermal change c. water separator Slows air down d. inline water
separator What is the rule-of-thumb amount of
lubricant that a lubricator should add to compressed air?

additive hopper compressor WBB
A pressure vacuum system has the following advantages:
Less dust is generated.
