How much N2 do you need offshore?
DNV offshore 2,000 and 5,000 gal ISO tanks are very common for offshore usage.
Just bring a Zone II converter and you are good to go.
Thanks, it make sense that there actual is a phase change from liquid to gas when the pressure is below Pc (1,071 psi), but what is then happening above Pc.
Why the increase in heat capacity even at 2,000 psi?
The graph was not attached in the first post, here it is.http://files.engineering.com/getfile.aspx?folder=0ce9c418-fff9-4ba4-ab45-d12fc790e120&file=CO2_Specific_heat_capacity_vs_temperature_.JPG
Can anybody explain why liquid CO2 has such a temperature dependant heat capacity, especially at lower pressure (~1,000 psi - see attached graph)?
From the PVT diagram I don't see any phase changes at the peak heat capacities.
I am planning a job where we will be injection liquid CO2 into an oil...
I would also think that 316SS would be good enough, but the vendor is recommending Aluminum-Bronze. I am just a bit concerned if the Aluminum-Bronze will work for high pH fluids.
I will be pumping 3 different fluids, portable water, 1-10% Sodium Chloride brine and 1% Sodium Carbonate Alkaline (pH ~ 11) fluids. What material is best to use for the pump Aluminum-Bronze or 316 Stainless Steel?
My main problem is iron (Fe2+ and Fe3+), basically rust is getting into my fluid...
