I have a query regarding multiple PSVs with same set pressure at what cases it can be considered for installation to protect an equipment instead of installing them in staggered manner.?
Hello,
In an attempt to design a shell & tube heat exchanger using Aspen EDR, I have designed a BHM exchanger to cool syngas from 46 DegC to 18.35 DegC using chilled water at 7 degC with excess area value of 0 %. However, when I used the same exchanger geometry generated by design mode in...
Hi All,
We intend to cool CO2 compressor suction stream of around 95000 KG/H from around 55 DegC to 44 DegC using chilled water of a temperature ranges between 5 DegC to 12 DegC. However, our CO2 suction stream pressure is as low as 0.985 Barg and by introducing the cooling unit this pressure...
Dear All,
We are in a process of purchasing a process simulation software for our company (Aspen Hysys/Aspen Plus/Unisim Design/Aveva Process Simulation/ Pro/II/ Chemcad/Symmetry etc). However, we need to go in competitive basis for selecting the best software.
For that we need to define scope...
Dear All,
Whenever I am selecting the Peng-Robinson fluid package in Hysys, I find estimated values of Binary Interaction Parameters (BIPs) that are used for the calculation. Anyone have an idea by what method those BIPs are estimated ? is it Group Contribution method? or another method? or they...

Hello All,
I want to simulate An ammonia absorber same as the attached sketch.The purpose of the simulation is to see the effect of increasing ammonia concentration in the solvent stream on the top product stream ammonia concentration. Could you please advise me what fluid package I should use...
Dear Experts,
In our complex we are currently facing higher sodium to phophate ratios problem in all our Boilers.
We have an integrated BFW system where interconnected de-aerators which are common for both HP BFW pumps and KP BFW pumps are installed. BFW is supplied to both the Ammonia trains...
Dear Expert,
I am trying to conduct Gibbs Free Energy Direct Minimization Calculations using Excel spreadsheet.I am following the procedures published in the attached PDF file. However, I am facing a problem in the initial estimate described in the paper (Highlighted in Yellow). In fact,I'm not...
