Describe the primary function of TK-820 and explain how its design supports this function.
TK-820's primary function is to store C20-C24 product. Its cone roof, mixer, and heaters support this function by providing stable storage conditions, preventing settling, and maintaining the required temperature.
Explain why M-820 is installed internally within TK-820, and what problem does it solve?
Explain why M-820 is installed internally within TK-820, and what problem does it solve?
M-820 is installed internally in TK-820 to prevent settling or layering of sludge and to maintain a homogeneous blend of different hydrocarbon densities.
Outline the purpose of E-820A/B/C and specify the heating medium utilized by these heaters.
Outline the purpose of E-820A/B/C and specify the heating medium utilized by these heaters.
E-820A/B/C's purpose is to maintain the temperature of the C20-C24 product within TK-820. They use 60 psig steam as the heating medium.
