“A continuous reactor P&ID: a feed tank and pump send feed through a steam preheater into a reactor; include temperature control of the steam valve and level control of the reactor outlet valve.”
اقرأ القرارات الكامنة وراءه.
TT-101 and TIC-101 adjust preheater steam.
LT-101 and LIC-101 control the reactor outlet.
Feed passes through the preheater before entering the reactor.
Both diaphragm control valves close on loss of actuator air.
Use this process P&ID for a conceptual continuous reactor system with preheated feed and temperature and level control loops.
أسئلة شائعة
Why control reactor level?
Level control maintains liquid inventory and a stable residence time in the reactor.
What does the preheater do?
It raises feed temperature before the feed enters the reactor.
Why are there two loops?
Reactor temperature and liquid inventory are separate process variables that need independent control.
