Does any body have experience on condensate refining? What is the route for condensate refining? There is a condensate stream with 97% in the range of Gas, Naphtha and middle distillate. In order to separation of different cuts, what are the design criteria for furnace, distillation tower and so...
What are the differences in vacuum tower arrangement for medium and heavy crude with the same No. of products (LVGO, MVGO, LLC, HLC, Slops and Vacuum Residue)?I mean No. of Beds, No. of refluxes and their location, location of side draws with respect to packing beds and No. of packing beds...
Could structured packings be used in Vacuum Towers Stripping Section? Is there any one that has experience on such application? What are the bottlenecks and difficulties?
I have a performance curve(steam rate vs. horsepower) for a single stage turbine (back pressure type)at a certain inlet/outlet steam conditions (temperature and pressure). How can I modify this curve for the other steam inlet/outlet conditions (such as different inlet pressure or temperature or...
Regarding to the industrial lube oil formulation I have some questions about the additives addition to the base oil as follows:
In some procedures, it is mentioned that after addition of additives (liquids or powders) the mixture should be mixed at 10 barg and 100^C for 2 hours.I do not know...
In some vaccum towers(specially in the packed towers) total liquids incoming to Slops Wax tray(I mean the first tray above the flash zone) is too high that this tray is already full of liquids and liquids over flow from tray's down-pipes or chimneis are there.
Is it usual?Has anyone measured...
hello,
There are three methods for feed entering to the vacuum towers(as I know):
1)Tangential
2)Tangential (vane type)
3)Radial (vane type)
Are there any person who compare the performance of these different types in all view points(flow distribution,phase separation,pressure...
In many texts it is mentioned that normal liquid velocity in the pipes ranges from 4-8 ft/sec.Are there any citeria for determining of fluid velocity in pipelines in corrosion errosion point of view?
DO YOU HAVE EVER SEEN ANY ARTICLE WITH COMPARE THE PERFORMANCE OF DIFFERENTS TOWER FEED NOZZLE INLET DEVICE SUCH TANGENCIAL/SCHOEPENTOETER/VAPOR HORN OR OTHERS?
I WOULD LIKE TO KNOW ABOUT THE VAPOR DISTRIBUTION OF THESE DIFFERENTS TOWER FEED NOZZLE INLET DEVICE IN PACKED COLUMNS.
DO YOU HAVE...

I have a question regarding the above subject as below:
There is a single stage steam turbine that is connected to a gear box and a pump.The rated BHP of turbine is equal to 1200 hp.But when we need lower BHP (near to 950 hp),we try to reduce the turbine RPM.But we face to big oscillation in...
