Dear srfish; I enclose estimated vapor fractions for coolers. As you can see Stg 5 and Stg7 won't have cooling and cooling after Stg 8 will liquified CO2. I don't know if with this vapor fractions, water vapor condensation could be ignored. Discharge Pressure (bara) St1 St2 St3 St4...

Hi all; I'm simulating CO2 compression with intercooling. I'm using and 8 stage compressor. I'm using water as refrigerant on the shell side (30-40ºC) At the cooling stages there is some water condensation and as the pressure goes up, gas density (kg/m3) increases as follow: 3.3 6.2 12.1...

Hello All, I would like to use Mathcad for Chemical Reactor Modelling and kinetics. I don't know if you could recommend me, which book is the best one dealing with these issues or if there are any web sites or forums specialized on these topics. Thanks in advance to everyone

Sorry for may delay but I haven been a little bit busy. I have been searching for industrial processes that deal with this problem and I have found that process for the production of H2O2 from H2 and O2 have this parameters: High pressure, low temperature and highly exothermic reaction. This...

First of all thank you for your answers. The process I was thinking of is a process where reagents are both in gas phase and are feed continuously and partially dissolved in the solvent to form the product in the liquid phase. The product will be taken continuously from the reactor together...

Hello, I´m wondering how to eliminate in an efficient way the heat generated during a highly exothermic gas-liquid-solid reaction, with this limitations: ·The reaction takes place at low temperatures (not higher than 50ºC) and high pressures (80-100 bar) ·Temperatures are needed to be kept...

I´m running a simulation and I´m trying to separate a stream with MeOH (98 %w) and H2O (2 %w). The natural way to separate this stream would be by distillation, obtaining MeOH on the distillate (bp 64.6 ºC) and water on the bottoms (bp 100 ºC),the problem is the distillation column would need...

Does any one can help me? I am looking for activation energy of Methyl Ether formation from MeOH . CH3-OH ---> CH3-0-CH3 + H2O What are the optimal conditions (P and T, catalyst) for these reaction to take place. Is there any database on the internet for activation energy of different...

Thank you all of you for your useful references

I am studying a process where methanol, oxygen, nitrogen and hydrogen is present in the gas stream and I would like to know if there is any technical paper, website or excel spreadsheet where ternary diagram construction and its formulas are explained to determine the flammable zone for the...

I am studying the solubility of different gases in alcohols , I have gather some data from bibliography and I have verified that with some gases like H2 its solubility in alcohols increase with increasing temperature, while the solubility of gases generally decreases with increasing...

Hello All, I have to design two fixed bed reactors one of then is liquid-solid reactor and the other is Gas-Liquid-Solid reactor both of then are upflow for liquid and gas. I would like to know literature references, webs or books (with design formulas and design examples) that could help me to...

I am running a simulation with Aspen Plus to study gas solubility in alcohols, the gas feed is compose by H2 O2 N2, the operation conditions are P= 90-150 bar (high pressure) and low temperatures (30-70 ºC). I would like to know what property method of those available in Aspen could calculate...

I´m running a simulation of a purifiaction process, where I have,oxigen, propane, propilene, propilene oxide and methanol at the top of the distillation column. I would like to know if there is any formula or graphic to calculate de flammability of this mixture at pressure and temperature...
