hello to reader,
We are carrying out thermal design of De-ethaniser and De-butaniser reboilers (kettle)for one of our gas processing units using Hot oil circulation(diesel) on tube side as heating medium.
I have questions about the same.
What should be the maximum heat flux which i should...
I want to know the chemical composition of Antioxidant / Antistatic addtivites used for 'jet fuels'.
Who are the suppliers? What should an inquiry consist of, if i want to order these chemicals?
What should be the criteria for the selection of these additives from available options?
Thanks.
While designing relief valve, we consider 10% overpressure as a criteria, in general. What does it really mean?
1) Does this mean that the pressure in the system will remain at 110% value all the time during relief? (provided the cause of overpressure has not been mitigated).
2) Now consider...
Does anyone have an experience of providing 'booster' pump in the cooling water return line?
Certain min. pressure at B/L in cooling water return line. After considering pressure drops in various exchangers, it is not possible to provide the required back pressure.
So, a pump in return line is...
Does anyone has an experience of using sealing compounds to arrest minor leakages from flanges in high pressure process plants?
how much reliable these compounds are?
Thanks,
We have the following Hyrogen compressors in our Diesel Hydrotreater. The op.pressure of reactor is of the range of 115 - 120 kg/cm2g.

We are about to carry out tightness test of a Diesel Hydrotreater reaction section for newly constructed plant. The op.pr. is 125 kg/cm2 range.
To carry out tightness test of this system with NITROGEN, Make-up gas and Recycle gas compressors can provide max upto 42 kg/cm2 g pressure because of...

A plant in refinery is constructed before more than a year. Due to unavoidable circumstances, it could not be commissioned. All the equipment and machinery are not in operation after they are erected.
Is there any standard which says about requirement of Hydrotest of heat exchanger if it is not...
We are planning for the start up of the Diesel Hydrotreater unit in refinery. The unit consist of Hydrotreater and Amine treating facility. The diesel feed is hving 2000 ppm Sulphur and the plant is designed to produce 500 ppm sulphur diesel.
The problem we are going to face is the Sour gas...
