sample cooler design

[coolcando]

I am new designer.
I am designing a sample cooler for Condensate sample. The Tie points for sampling station are discharge and suction of Condensate pump. The condensate is at 90 C and to be cooled upto 25 C. The line run will be around 20 feet (Tieing from discharge Pressure gauge to Suction drain valve of the pump).

Since Pressure drop is very high(800 Kpa) and line length is not much , the flow rate is huge ( through 1" line).

What is a good idea to control the flow of sample ? Use an orifice or a Globe valve ??

Utility water at 10 C/300 Kpa is used for cooling. How can I calculate Utility water flowrate?

Pretty standard design. You can probably find examples in your plant now if you go out and look.

Normal is block valves in and out of cooler on process and utility side. Make sure your sample point is after the cooler and before the block valve. Valve on sample point should be a needle valve to limit the flow of sampled material.

Consider the purchase of a sample flask from a reputable vendor.

Control the flow into the flask via a needle valve and in accordence with mfrs requirements.

Don't get burned....

I do not recommend that you design your own.
Check out the following:
Graham Heliflow Heat Exchanger
Product Overview
The Graham Heliflow is a unique type of shell and tube heat exchanger. The tubes in the Heliflow are arranged in parallel, starting with an inlet manifold on one end, and terminating at an outlet manifold on the opposite end. The tube bundle is wound into a helical pattern. This coiled construction creates a spiral flow path for the fluid inside the coil. Heliflow Heat Exchanger spiral flow path
Heliflow Heat Exchanger parts Each tube is in close contact with the tube above and below it. The coiled tube bundle is fit into a two piece casing. When the casing is tightened, it is designed to slightly compress the tubes. Because of the tight fit, the shellside fluid is forced to circulate in a spiral patten which is created by the open spaces between the coils.

my previous employer used almost exclusively

with good results (including highly toxic/carcinogenic streams)

Try these too.

Quite new in heat exchangers thermal and mechanical design.
Please recomend software, books, templates, methodology and more....

Thank you
