Hi jari001,
Thank you for responding to my query. I have attached a snapshot and a copy of the control panel messages which may also be helpful.
Hi pmoneysh,
Thank you for responding to my query. I did use the NIST Databank for those chemicals which i had to define by drawing their...
Hi,
Currently I am running a steady state simulation, on ASPEN PLUS (I have only a few years of experience in the usage of ASPEN PLUS), for a Pharmaceutical plant. It's a batch process and I am using a BATCHSEP model in this simulation. The feed comprises Na2co3 along with Dichloromethane...
Initial investigations found various stages of corrosion in different sections of the fractionator column of this RFCC Unit although the investigation is still ongoing by a team comprising the Licensor and our engineering consultant and we expect to get more information on the extent of the...
Hi,
As part of an ongoing exercise in the company to debottleneck a 70 KBPD existing refinery one of the issues that needed a resolution was the corrosion issues in an RFCC unit in order to debottleneck it. Following below are options to debottleneck the same, which under discussion right now...
Generally the equipment nozzles are sized to match the connected pipe work and the connected pipe work are sized to meet pressure drop and velocity requirements based on a a given flow of fluids through them (some design standards like the Shell DEP on 2 phase / 3 phase Separators mention a...
Yes I faced a similar situation few years ago with an operating company i worked with. However it was understood that at alltimes the mating relief valve inlet pipe ND would match the relief valve inlet ND..irrespective of what the internal diameter of the relief valve inlet or the nozzle would...
The documentation that may have accompanied your copy of the HYSYS software from the vendor has a detailed discussion in one of its chapter regarding the various types of volumes and volumetric flow rates used by HYSYS in ite simulation.
Yes they are obtained experimentally for the said compounds, pure components and mixtures with these experiments conducted in a certain range of temperatures and pressures. Thermodynamic packages like UNIFAC use the Group Contribution Method and in this method the functional groups present on...
Villivord,
Before you look at anything else, I would reckon that with all the system information that you have with you viz. buliding height, static head friction losses etc. you should be able to draw a rough sketch of the entire pumping system with the 3 safety showers located at various...
Curvyrace,
ASME B31.1, as you may be aware, is a Code which needs to be followed / adhered to to meet permit / regulations / certification requirements. API is a Standard which would be used as an aid to applying good engineering practices in the design. Hence as you may notice, the language of...
As far as I know, based on the engineering school I came from, OP would have studied at least one course of heat transfer and some basic thermo in his engineering school which should be enough for him to solve this problem of an elementary nature....Hence OP needs to pick up those books of that...
curvyrace,
I am not sure a diverter valve is a good idea since one of the lines from the out let of this valve leads to a relief valve. Though I have not done much of these boiler / steam generation systems what I know is as per any local regulations / API etc. the inlet pipe work leading upto...
Latexman is right. This is an elementary problem involving whatever heat transfer and thermodynamics that you may have studied during your engineering school days.
Go ahead..remove the collecting dust on your textbooks !...[bigsmile] ...Look at the problem again and you may be able to solve it...
Do you have more information to share on your query other than what you have given? You have said that your results are acceptable. Hence I assume you had used a proper calculation / simulation procedure to arrive at the results. Therefore your concern is not understood.
Nevertheless, if you...
your idea need to be first tested against proper heat exchange calculations since the heat transfer characteristics (heat exchanger area, heat transfer coefficients etc.) may be totally different for a kettle exchanger and a double pipe exchanger since you are stating this proposal...
Hello folks,
I am not sure whether this post belongs here but considering the fact that the other forums do not seem to discuss what I wish to state in my post I thought that this may be the most appropriate foreum of them all :)
I am a Process Design / Systems Engineer with 20 plus years of...
Hmmmm....interesting. Then I am wondering why the AGRU plant's licensor in our NGL facility suggested HEP as a promoting agent to the MDEA solution that he proposed for removal of CO2 and H2S i.e. bringing their content down to ppm levels in the treated gas. I will try to find out why.
Thanks...
Just to let all of you know.....
the colour coding that was followed by my current company on the field for oil and gas pipinig / pipelines was totally the opposite of what was being used in the oil company I worked with earlier [bigsmile]
Hence i realised that although there may be an...
Yes Kald you are right :). There are many in the market and hence that poses a challenge as to which one is good or better than the rest.
I worked on QUE$TOR before in another company previous to this one. I thought their software was also good i.e. giving a "realistic" picture of the actual...
