Another program that is great is BR&E's PROMAX. It is not free , but is excellent. If you do not have the software then you can hire a consultant. It's not worth writing your own on this. There are other process simulators such as VMGsim and HYSYS. I hope this helps.

Reply to TBP. I am glad that you confirmed the lack of information on steam injection lines for heavy oil as well. I have looked in almost every text book on steam lines and even heavy oil production and cannot find information on erosion velocities in steam injection lines. In addition, I...

Thanks for the information. I should have been a bit clearer on what type of steam line I was referring to. It is a steam injection line for heavy oil production that normally operates at pressures greater than 10 MPa. As such the condensate and steam are never separated ( this is standard...

I have looked almost everywhere in order to find recommended erosion velocities for wet i.e. 80% quality steam and have not found much data. What I have found (in Crane and other text books) is that one must design pipes for less than the 100% (saturated) velocities. But Crane and others do...

I am looking at generating steam by using heat exchangers to utilize excess heat from the process. This 2 phase mixture then goes to a separator to produce high pressure steam (about 900 psig). There is also a pump around which takes any liquid hold-up and pumps the by now hot water through...

Reply to ProcessDr and 25362: I have one more question on the tower size for this type of design. What tower size have you come across based on your experience? Kister states that the unbaffled design is applicable in tower diameters of less than 3 feet. (He also states that this design is...

Skoutso you have provided two liquid hold-up times; one for the bottoms product and one for the vaporized portion coming from the reboiler. This would indicate a baffled bottom section of the tower if I interpret this correctly. Yet, the design I was given does not have a baffle. I would...

Reply to 25362: The condensate is the bottoms product which meets an RVP specification. The design I am referring to has only one outlet from the bottom of the tower. This bottoms product is then split into two streams: one goes to the pipeline and one if fed through the forced circulation...

Thanks skoutso for the information. Do you know where I can get specific design information on the forced recirculation design? This would be helpful.

I am evaluating a stabilizer design that has a direct fired heater (reboiler) with pump. This design combines takes the condensate off of the bottom and some of the condensate goes to a pipeline, but the rest is fed through the reboiler and combined with the liquid from the last tray! There is...
