【Daily Question】August 1: Three-way valve for the distillation column bottom slurry in the catalytic cracking unit
Thread Content
One daily activity question (single-choice question): In actual production, the reason why the three-way valve for the distillation column bottom slurry in a catalytic cracking unit is used as little as possible to allow heat flow is ( ). A. Increase the flow rate of the slurry inside the heat exchanger tubes to prevent coking. B. Prevent wear on the heat transfer pipelines. C. Reduce the amount of energy that needs to be recovered. D. Minimize wear on the three-way valves. Answer: A. Increase the flow rate of the slurry inside the heat exchanger tubes to prevent coking.

Oh, this feeling is the first A, right?
In actual production, the reason why the three-way valve for the distillation column bottom slurry in catalytic cracking units is kept away from heat flow as much as possible is (A) to increase the flow velocity of the slurry within the heat exchanger tubes and prevent coking.
A. Increase the flow velocity of the slurry inside the heat exchanger tubes to prevent coking
