it could be the quality you are using. from my end i can see the sheets and what is written very good

I'm sorry i haven't worked with v11.

@@adrianl6811 can you send the aspen hysys which you are using . I will install My email: [email protected]

Yes, lots of Caribbean people have Indian ancestry.

I didn't use a tutorial. It was based on my experiences of characterizing hypothetical crudes from boiling point data acquired by lab analysis.

You can add as many reactions to the set as you need.

For any stream set the vapor fraction to zero. You must specify a pressure but not a temperature. The temperature at which the first droplet of liquid forms will be calculated. You can also use a stream envelope utility to see the phase equilibrium data.

You can assign a Utility to the energy stream for reboiler and condenser. Just use a utility that can satisfy the temperature requirements.

Just double click the energy stream and choose a utility

@@adrianl6811 thanks. i got it now.

Thank you

What's kintecus?

@@adrianl6811 The Kintecus chemical simulation software, chemical kinetics program, chemical kinetics software with full regression/optimization abilities and has been cited in over 400+ peer reviewed journals: SCIENCE, NATURE, J. Phys. Chem.A, PCCP, J. Biol. Chem., Plas. Chem. Plas. Proc., Int. J. Chem. React. Tech, Arch. Bio. Chem. Bio. Phys., etc. Click the Papers button on the left side to see some! Kintecus is a powerful Industrial Strength/Research Grade chemical modeling software for simulation and optimization/regression of combustion, nuclear, biological, enzyme, atmospheric and many other chemical kinetic and equilibrium processes. KINTECUS - What can it do ? ________________________________________ Kintecus is a compiler to model and regress/fit/optimize the reactions of chemical, biological, nuclear and atmospheric chemical kinetic and equilibrium processes. A quick overview of the main features: • A very thorough and easy to use Uncertainty Analysis (Monte Carlo sampling runs) to calculate "real-life" averaged behaviors with confidence bands/standard deviations of your chemical system given Gaussian/Poisson/Uniform deviations. • Fit/Optimize/Regress rate constants, initial concentrations, Lindemann/Troe/SRI/LT parameters, enhanced third body factors, initial temperature, residence time, energy of activation and many other parameters against your dataset(s). Note that Kintecus will actually fit the parameters at EXACTLY the time your data was measured. Unlike other programs, Kintecus DOES NOT interpolate a function against your data and then fit the values against this interpolation. There is absolutely no need to “clean” your data, suggest interpolation methods nor specify timing meshes against your experimental data since Kintecus calculates values at exactly the times you specify in your experimental datafile. Kintecus V3.8 and above can also perform accurate bootstrapping of errors. • Global Data Regression/Fitting/Optimization Analysis: Kintecus V5.0 and up now supports an extremely powerful global data regression/fitting/analysis. You can regress or fit or optimize multiple datasets that have multiple initial conditions such as temperatures, pressures, concentrations or any combination and with data sets that have different time scales, different time steps, different species, temperature profiles, heat output, different amount of data points, etc. There are many sample Kintecus-Excel worksheets demonstrating some basics of this new global regression. • Fitting/Regressing with Arbitrary Constraints/Conditions/Heat Output: Apply any type of constraints of any type of complexity in equation form between any variable or constants for use in regression/fitting. • Local Variable Regression: One can now also regress/fit the initial conditions for a species (or temperature) in any of the initial_conditions.txt file (some programs call this local variable fitting/regression). This can be done by suffixing any numeric value in an initial condition file with a question mark, “?”. Kintecus V5.00 and up also supports the ability to regress/fit against heat generated during a reaction. • User Defined Chemical Rate Equations: The special USER chemical kinetic function is new in Kintecus V6.51. You can use it to define your own chemical kinetic rate equations of any complexity using ANY mathematical form. • Full output of global normalized sensitivity coefficients selectable at any specified time or times. Normalized sensitivity coefficients are used in accurate mechanism reduction, determining which reactions are the main sources and sinks (network analysis) and which also shows which reactions require accurate rate constants and which ones can have essentially guessed rate constants. Kintecus V6.8 and up now include the Atropos system for full chemical mechanism elucidation and automatic reduction. • The ability to use profiles or perturbations of any wave pattern for any species, temperature, volume or hv. Using profiles/perturbations can also be used for studying very realistic systems, such as quenching affects, dissolution of various gases into a system over time, induction of current into a system, heat flow into a system, a piston compressing the reaction chamber and so on. • Built in support for special reactions such as: reactions involving third-bodies (M), fall-off reactions (Troe, Lindemann, SRI, JPL forms, MCM forms, etc.) , enhanced third bodies, exclusive multiple enhanced third bodies, vibrational transfer reactions (Landau-Teller) and many others. • Some heterogeneous chemistry can be modeled. For example, a species in the aqueous phase will not contribute to the overall pressure in the system or be involved in third-body reactions or fall- off reactions. Gaseous species can “enter” other phases through out a simulation and vice-versa. • *The ability to do reactions in a continuous stirred tank reactor or homogenized plug-flow reactors (CSTR,PFR) with multiple inlets and outlets and independent FLOW temperatures. * • Kintecus V5.5 and up now support some of the special IUPAC chemical kinetics forms from the Master Chemical Mechanism (MCM) ( see mcm.leeds.ac.uk/MCM/parameters/complex.htt , www.iupac-kinetic.ch.cam.ac.uk/ and/or iupac.pole-ether.fr/ or Google/Bing "Master Chemical Mechanism"). Most of the these forms pertain with special pressure fall-off reactions that cannot be fully cast into the traditional Troe, Lindemann forms. • The ability to convert Chemkin-II/Chemkin-III/Senkin models to Kintecus format. Kintecus can run almost any converted Chemkin model. Once converted, you may apply any Kintecus feature to the system. Do not be surprised to see the converted system run much faster! • Comes with multiple thermodynamic databases containing thermodynamic data (G,E,H,S,Cp,K,Kp) on several thousand species over a wide temperature range (200K-6000K)! • Reactions, adiabatic or non-adiabatic (isothermal, any temperature program), can be performed under isochoric (constant volume) or isobaric (constant pressure) with a simple flick of a switch along with optional volume, temperature, concentration wave perturbations or set profiles. • The ability to model thousands and thousands of reactions in a relatively short time. Kintecus has been used with models as large as 120,000+ chemical reactions. You will not find anything faster than Kintecus. • Multiple-well, Multiple-channel Reactions Utilizing Chebyshev Polynomials and PLOG reactions. Kintecus V5.5 and up now support the Chebyshev expansions proposed by Venkatesh for representing pressure fall off and temperature dependant rates of multiple well reactions. Please see those references for the list of equations that are utilized in Kintecus to calculate those rates. • Global Equilibrium calculations. Why design a kinetic scheme when all you have to do is give Kintecus a listing of all the relevant species in your system. No need for ANY REACTIONS! In fact, you do not even have to specify which species are reactions or products! You can even perform phase stability plots of systems over ranges of temperatures, pressures, volumes and concentrations of other species. You can even fit/optimize experimental data against your equilibrium model. • Perform eigenvalue-eigenvector analysis of the Jacobians of the system as the model runs. This is useful for metabolic control analysis (stability analysis). • Easily perform four types of scanning: combinatorial, parallel, parallel-repeat and sequential. • A powerful parser with automatic mass & charge balance checker for those reactions that the graduate student "supposedly" entered in correctly but the model is yielding incorrect results or is divergent. Do you know a kinetics program that can completely parse and check for mass/charge balance on a reaction like this: Rate Constants , (m and Ea), REACTIONS: 1.234e-20, 1.2, 3000,CH3(((NO2)3(CO)93)3 (CH2)9)+23.30H2O+ + Co2 ==> A--- + B++++ +C+C+C+C+C Or how about this: Rate Constants , REACTIONS: 5.043e+20 , 3.43234 (CH4(N(PO342)43(CH3)3)34)(Os(S7)8)34++++ + 199.432 X++++ 5CH5+ ==>5.434 Some_Really_Funky_Long_Enzyme_Name+ 8 HCl + HCO3- This smart mass balance can be used for biological and nuclear reactions! Kintecus also provides duplicate reaction and species checking. • As you can see in the above reaction, fractional coefficients for species! Now you can finally model that last step in the Oregonator or crunch 100 elementary reaction steps in one reaction step! • Dynamic mode for feedback and/or dynamic simulation runs and external user control of Kintecus • Much, much more!

@@scinix8067 very cool. Thanks for sharing.

Most welcome. One day i will get some more done. :) But very happy it helps some folks out.

Not sure what you mean. Please explain a bit more.

@@adrianl6811 I am sorry. I am just a beginner. I need to find heat duty from the distillation using sep2 block. But there is recovery of components. Water. Methane n ethanol in overhead n bottom stream. I wonder how can we include it in the simulation.

@@baidurimumtazah5215 you should probably be using shortcut distillation column instead of sep2 block. You can specify recoveries and it outputs the duties. See the first video i posted on distillation.

@@adrianl6811 yes, we also view some video, and we are thinking to use radfav too. But the question wants us to use sep2. The question: a two-feed, two product distillation column operating at 1 atm is to be simulated using the Sep2 block. The components are methanol, water and normal hexane. You may assume that the system thermodynamics can be represented by an ideal vapor phase and the UNIFAC correlation for the liquid phase. The componential flow rates of the first feeds are 50 lb mol/h of methanol and 100 lb mol.h of water and is a saturated liquid at 14.696 psi. The second feed flow rate is 150 lb mol/h of pure n-hexane at 120° F and 14.696 psi. Both feeds are at 1 atm and are saturated liquids. 1. Perform the mass and energy balance simulations using the following column specifications: a. One half of the methanol fed is to be recovered in the overhead product b. 99% of the water fed is recovered in the overhead product c. 99% of the n-hexane fed is recovered in the bottom product

@@baidurimumtazah5215 Sorry i can't see how this can be done using Sep2 block. Please ask your teacher. I would like to see how this can be done.

Agreed I made an error there

@@adrianl6811 That's no problem. I was just feeling bad beacause I didn't undertand that at this moment and I started to write down a few equations about molar fractions and so on and after 2 minutes I felt dumb that you were only speaking about % :P (this is the effect teachers have on me lol)

You should create another method set and associate it with the 2nd component list. Then in the flow sheet change the basis of the streams and unit ops that you wish to use the second component set with. Hysys will add "stream cutters" to create the transition from one basis to the other automatically. You may have to adjust the settings on the stream cutters as needed to get convergence.

@@adrianl6811 I don't see where am I supposed to do so. I asked the question on SE, you will find pictures of what I did. Can you either answer my question on this website with a few screenshots or guide me to find the "method set". And thank you very much for your great series of videos. engineering.stackexchange.com/questions/29631/how-to-use-a-specific-list-of-components-in-a-stream-in-aspen-hysys

@@orthoh2224 you associate the fluid package "Basis 2" with your second component list. Then in the flow sheet environment change the basis for the required streams and unit ops to Basis 2. Hysys uses the terms Fluid Package and Property Methods interchangeable.

Been meaning to get to it. Hopefully this week.

They are all listed on his channel.

Are you installing the psuedocomponent from the boiling point range or are you attempting to install from the crude database?

Adrian L, I’m using the boiling point range for the assay

@@gabrielaojedar send me screen shot of error. You're not using any database here so shouldn't have an issue. [email protected]

Your welcome. Happy I could help.

Increases in pressure will result in higher temperatures according to the equation of state that is applicable. Although these temperature changes may be small when compared to temperature changes associated with the heat transferred via the pipe walls to the surroundings.

Thank you.
