Describe the purpose of the nitrogen blanket from D-801 in relation to TK-812. Why is it important?
Describe the purpose of the nitrogen blanket from D-801 in relation to TK-812. Why is it important?
The nitrogen blanket from D-801 is used to prevent moisture and oxygen contamination in TK-812. This is important to maintain product quality and prevent potential hazards like oxidation or degradation of the C12 product.
Where does the C12 product that is routed by P-812 (C12 Loading Pump) originate, and what are the possible destinations for this product?
Where does the C12 product that is routed by P-812 (C12 Loading Pump) originate, and what are the possible destinations for this product?
The C12 product routed by P-812 originates from TK-812 (C12 Product Tank). The possible destinations for the product are the C12 Loading Rack or the Heavy Rerun Header.
Explain why TK-812 is equipped with a pressure-vacuum vent device. What could happen if it lacked this?
Explain why TK-812 is equipped with a pressure-vacuum vent device. What could happen if it lacked this?
TK-812 is equipped with a pressure-vacuum vent device to protect the tank from overpressure or vacuum conditions. Without it, excessive pressure could cause the tank to rupture, while a vacuum could cause the tank to collapse.
Based on the equipment descriptions, what is the main purpose of M-812 inside TK-812, and how does it achieve this purpose?

Study Notes
- TK-812 (C12 Product Tank) receives C12 product from the overhead of T-440.
- TK-812 receives and sends C12 product from/to the inlet of TK-1812 in Unit 1798.
- C12 product can be sent/received to/from the outlet line of TK-1812 in Unit 1798 via the outlet of TK-812.
- P-812 (C12 Loading Pump) routes the C12 product to the C12 Loading Rack or the Heavy Rerun Header.
- TK-812 has an internal mixer, M-812 (C12 Product Tank Mixer).
- TK-812 is maintained under a nitrogen blanket from D-801 to prevent moisture or oxygen contamination.
TK-812 (C12 Product Tank)
- TK-812 is a cone roof tank, which is a cylindrical tank with a fixed, cone-shaped roof permanently attached to the tank shell.
- Cone roof tanks generally operate at atmospheric pressure.
- These tanks are equipped with pressure-vacuum vent devices to protect against overpressure or vacuum.
- TK-812 measures 55’D x 48’L and includes a cone roof and a mixer.
- Installed to store C12 product.
- Product enters and exits TK-812 at the bottom.
M-812 (C12 Product Tank Mixer)
- M-812 is installed internally within TK-812.
- It prevents settling or layering of sludge.
- It helps maintain a homogeneous blend of different hydrocarbon densities.
- M-812 is driven by a 7.5HP 12885 GPM induction electric motor.
P-812 (C12 Loading Pump)
- P-812 is a single-stage centrifugal pump.
- It is driven by a 30 HP 3535 RPM horizontally-mounted, induction electric motor.
- It routes C12 product from TK-812 to the C12 Loading Rack.
