Hello
Does anyone have experience with the following problem?
Im working in a petroleum refinery, and we are trying improve the sulfur recovery units trying to separate the h2s from the nh3 coming from the sour water stripping units (trying to concentrate the h2s composition over the nh3 in...
Hi,
Anyone could help me, telling me how to calculate the Energy Intensity Index. I know this is a propietary method of Solomon (known as Solomon Index as well).
My question is, If I require to evaluate the EII of certain unit (in a petroleum refinery in this case), where do I get the...
Thank you Christine,
You are right, and I was completely lost.
I checked with B-jac in one case for the same exchanger, and the shell weght reported is the complete exchanger, as you say.
Thank you very much.
Hello,
I have found that the print outs of my HTRI Xchanger Suite 4.0 have a mistake with the equipment weights reported on the data sheet.
The bundle weight is showed in the place of "full of water weight", and the full of water´s weight is reported on the place of "Bundle weight". Even...
Hi,
Anybody has information about a treatment for the spent caustic from refineries through the contact with Boilers flue gas.
I have read that this is a kind of new process for the treatment of the spent caustic, using the CO2 from this gas stream.
Thanks a lot,
Anybody has any idea of the recommended minimum distance between the crude tower feed inlet and the upper tray in the flash zone?, Where could I find this information?
Thanks.
Hello,
Anybody have experience with the inertization of crude cone-roof tanks when the diameter exceeds certain diameter.
I need to design a coneroof tank, and according some legal requirement, when the product storaged in this kind of tank is crude, and the diameter exceeds 50 m, then is...
Hi,
Does anyone have any experience or idea of the alternative of increase the discharge pressure of a recip compressor, to levels near the MAWP.
Nobody in the Dresser has answered my questions (they say they have to do a study of 6 weeks and I need some idea now).
I know that there is a...
I have one Hysys simulation done by somebody else, and they keep the actual gas flow constant, when they change operational conditions.
I think the only constant is the piston displacement, but actual gas flow capacity is function of the operational conditions. The pressure 14.4 used as...
Hi,
I wonder if anybody knows what condition represent the Actual gas flow in Hysys.
Is it the actual operational condition (temperature and pressure), or is at 14.4 psia and actual temperature which is the usual "Actual" condition for reciprocating compresors?
Thanks,
Hi guys,
Anybody has a way to estimate the heat loss of an insulated stirred reactor, or what is the same, the estimation of insulation thickness. (In this case is a batch process and I want to figure the need of heating coils out)
I have found an useful freeware program "3E Plus 3.2", and I...
Hi Homayun,
There are no meters installed in the flare header, and yes, Im wondering if is possible to have any idea of the amount of leakages to the flare...(ton/year, or US$/year, just to justify the implementation of reduction of leakages strategies...something like LDAR leak detection and...
Hellow,
My problem is trying to evaluate the leaks to the flare in a natural gas plant. The fact is that several valves (ball and control valves) are leaking, which is easily checked because inmediatly downstream of the valve, there is ice covering a small portion of the pipe.
Solving the...
KrugerJR,
The program you can find it at
http://www.epa.gov/ttn/chief/software/tanks/index.html
and is based on API-42 Chapter 12 methodology.
