Hi all In pro ii simulation, how can I insert two or more simulation flowsheet in one window? If I duplicate a flowsheet, in simulation window, how can I change one flowsheet without affecting other one? Besr Regards

dear all in pro ii simulation software, we define two oil streams with different sulfur content, for example for stream 1 sulfure content is 2% and for stream 2 , sulfur content is 3%, but in output, software automatically distribute sulfure content between two streams, that is different from...

Hi all I am going to design a caustic scrubber for refinery off gas to capture h2s. Is there any procedure for measurement of sodium sulfide(na2s) and sodium hydrosulfide(nash) separately in an aqueous solution? best regards s.mataji

Hi all How can vapour pressure of spent caustic from the bottom of scrubber tower be calculated? Tower pressure is 6.5 barg and temperature is 70 deg c thanks smk

Thanks all. The solution in my mind is to alocate existing gas oil stripper for kerosene and kerpsene stripper to gas oil. Installation valving system for change over should be considered.

Thanks all. I EXAMINED ALL CASES. TOWER HAS BEEN DESIGNED FOR 4500 BPSD . ID IS 1100 MM.THER IS NO ROOM FOR IMPROVMENT OF JET FLOODING, DC BACK UP .ETC..

sorry,11000 BPSD of kerosene is correct.

I want to modify design of sour water stripper for improvement of NH3 CONTENT in stripped sour water. Is it required second tower? what software is suitable for sour water stripper with high ammonia content?

normal design is 4500 bpsd kerosene and 12000 bpsd gas oil. with some feeds we kerosene cut is 110000 bpsd and gas oil is 4500 bpsd. kerosene stripper can,nt handle this large flowrate of liquid.

In our condensate distillation unit , kerosene cut and gas oil cut rates frequently change dramatically, that exceeds capacity of kerosene stripper. We are thinking about installation of valving system to change strippers,and allocate gas oil stripper which is larger, in kerosene service and...

Hi all I want to increse capacity od kerosene side stripper of crude atmospheric distillation column. I am considering installation of structural packing . Existing internal is 8 valve trays .Is ther any experience of side stripper with structural packing? best Regards shahabemk

Thank you all line size of kerosene draw off to the stripper is 6 " and for gas oil stripper is 12 "

Hi all I am working for a revamp project for crude disstilation unit. The atmospheric column has two side stripper. Level controler of stripper botton send signal to a control valve of draw off line to stripper. Which type is suitable for this stream' butterfly or globe valve type ? Best...

HI ALL PLEASE LET ME KNOW HOW TO CALCULATE SNIFFER RING CROSS SECTION AREA. DIMENSIONS ARE : L=80 MM H= 200 MM THICKNESS T1=12 MM THICKNESS T2= 12 MM THANKS

Dear all I am checking the design calculation of a pressure vessel. The calculation sheet is attached. I can,t understand how 18 mm is selected as minimum thickness after forming. Would you please help me...

Dear all I am going to design a pipeline for hydrogen sulfide transportation from amine stripper reflux drum to sulfur recovery unit.The distance is very long?( about 4 km). would you please inform me about the specification of such hazardous material pipeline? Is it necessary to be jacketed...
