Heat Exchangers Cost Estimate

[EmmanuelTop]

Good evening to forum members,

Knowing the total surface area required for heat transfer application, materials of construction and pressure rating of specific service (assuming that all other criteria are satisfied - velocity range, pressure drop margin etc.), is it possible to obtain approximate value of equipment cost - with or without installation expenses?

Speaking of shell & tube heat exchangers for this particular case, instead of floating these queries to equipment manufacturing vendors, is there another way to calculate approximate (+/- 20% error) total cost of heat transfer equipment involved in the service? And without any industrial software, if possible.

Thank you in advance,

Hi Emmanuel,

I'm not a cost engineer but... you will not get a sufficiently accurate estimate with only a SA and simply assuming other design criteria will be met, i.e. not knowing what the beast will look like. The no. of shells would be the very least thing to know. You have to work out the configuration first, or your cost engineer will frown at you and not help you further.
Then, even if you know exactly what exchanger you want, you will not have a clear idea about installation expense without knowing where and how it will be installed. Take your favorite cost engineer outside in the plant on a sunny afternoon.

Yes there are booklets available that provide engineering cost indices, google will help you further. Please don't bother equipment manufacturers with a request for quotation that is so awfully global that it does not smell like it comes from someone with a budget to spend!
