Help me in pump sizing for cooling tower water circulation 2

[Asisraja D]

Hello professionals
I am working as a project engineer in a chemical company. We are starting a new project with small pilot plant construction and I will list out the equipments & condensers here. The question is as a project engineer I have got less details from our process engineering group so i want your help to design a pump based on the details I have in my hands so please bear me in this.

Overall reactors :
Reactor MS/SS316 : 1.0 KL - 1 No's (Jacket volume 200 Liters)
Reactor GLR : 1.0 KL - 1 No's (Jacket volume 200 Liters)
Reactor MS/GLR/GMP : 630 L - 1 No's (Jacket volume 160 Liters)
Reactor MS/GLR/GMP : 630 L - 1 No's (Jacket volume 160 Liters)
Reactor SS304/SS316/GMP: 600 L - 1 No's (Jacket volume unknown)
Reactor MS/GLR/GMP : 250 L - 1 No's (Jacket volume unknown)


Overall condensers :
1. SS316 - 4 Sq.Mtr - 2 No's (Box type)(Overall Tube volume for both 24.64 Liters)
2. SS316 - 8 Sq.Mtr - 2 No's (Box type) (Overall tube volume for both 47.52 Liters)
3. Graphite condenser - 6 Sq.Mtr - 3 No's (Block type & utility volume unknown)
4. Graphite condenser - 8 Sq.Mtr - 1 No's (Block type & utility volume unknown)

Cooling towers (150 TR) - 2 No's
Cooling tower-1 for only reactors & condensers
Cooling tower-2 for 20 TR (-10 Deg.C) Brine chiller's condenser cooling purposes.

Header routing is like "L" Shape so consider
length 1 - 21 Meters & Length 2 - 12 meters.

So i have to design two pumps for two cooling towers based on the above details.

sorry for editing the question because it took hard to collect the data from our process team. i will update my planned PFD (Process flow diagram) Soon.

Thanks in advance.

LittleInch sir
Yes. It will not more than 10 Deg.C because normally our rule of thumb during the Operational qualification we use steam for jacket and the process fluid is RO water so the maximum temperature we can achieve around 97 Deg.C using wet steam only then we apply cooling tower water at 97 Deg.C for jacket to reduce the RO water temperature. This process will be performed by us before hand over the equipment to the process.

Your inlet to outlet temp of your cooling tower is probably no more than 10 C and possibly less.

anyhow the maximum del-t for evaporative induced draft cooling tower is 5 Deg.C (ROT). so it will be less thank 10 Deg.C only.
