I'd like to liquefy a CO2 stream (assume 99.9% purity). 5-10 T/d, 20 bar, 40C incoming, cooling to -19.5C at 20 bar.
I understand the heat transfer calcs, and it comes out to around 26 kW cooling required. Given the small scale, I was thinking of something like R-143A as the refrigerant.
This is where I'd like some advice. I assume a packaged refrigeration system is best, so are there any recommendations for vendors? I'd also like to work out the numbers on my own for sizing the refrigerant compressor and condensing coil, so a little advice on this end would be helpful as well (even just a book).
I'd then use a shell in tube or U-tube heat exchanger to cool the CO2, and I'm comfortable running these calcs.
