Hello All.

 

In attachment I placed sketch with current situation and proposed redesign.

In normal case there is no flow through EA-1. This cooler is used periodically in order to bypass tower when it is shut down. In EA-1 liquid is cooled and in EA-2 vapour are cooled and condensed. Duty is 1 and 9 MW respectively. 

 

I would like to remove EA-1 and use only EA-2 in both cases: 1) normal operation and 2) bypass of the tower.

 

My concern is if new solution will allow to on-line switch between Case 2 and 1 (start up of the tower). I think that when valves V1-V5 will be properly managed it could be possible. When Case 2 will be operated can only a part of EA-2 (one bundle) be in use? Can you provide me your opinion about this issue?

 

 

 

Kindly Regards

It is normal, when you have a HX to start up, means that this is an important equipment for shutdown procedure.

 

 

As breizh said, look the startup and shutdown procedure and ask for the operator's approval.
