Hi to all,

 

1. Which type of heat-exchanger will be used for cooling effluent with 25000mg/l of liquid specific gravity around 1. TSS - 100mg/l and pH 7-8.

 

Effluent should be cooled from 60 to 35 dec C. flow rate 133m3/hr with 2.5bar_g pressure.

 

2. If i use shell and tube heat exchanger (effluent in tube side due to corrosive in nature) in EDR, tube velocity is around 0.06-1.1m/s. is this velocity is enough to overcome the particle deposit/choke in the tube?

Hi ,

I would suggest a spiral heat exchanger if you are worried about deposit (easy to clean) , a brochure is  attached .

Hope this is helping you.

is there any sizing calculation sheet/software to find the size of spiral heat-exchanger and cost also?

 

I am using Aspen EDR. No more spiral type in EDR.

Hi ,

I believe these type of HX is included in software packages like HTRI . I don't know about your package .Anyway you will find a method to size this equipment in the attachment .

Regarding cost , only vendor can support .

To make it simple your should issue a spec sheet and ask vendor like Alfa Laval to size and quote the equipment .

 

Note :Engineering is hard work , not copy and paste. You need to build your expertise , consult peers and senior engineers /managers within your organization .

 

My view
