Has anyone ever use a reliable oil-in-water(OIW) analyzer with some success in the heavy oil industry in particular the SAGD(Steam Assisted Gravity Drainage) application in Alberta?
We want to accurately monitor the OIW continously coming out from the FWKO/Treater in the Bitumen Treating area...
We have a Spiral Heat Exchanger(SHE) downstream of our FWKO(free water knock-out) & Treater vessel where we want to cool the produced water(Alberta SAGD heavy oil) from 110C to 92C using glycol entering at 60C. The SHE is not performing to spec in terms of pressure drop & temp. Maximum duration...
Thanks John, owg & epoisses. For a moment I thought my message was forgotten. Your comments are valuable to me and I hope others in future who are in similar situation will also find these comments useful.
If anyone has an excerpt of this "Rule of Thumb" from Chemical Prcoeesing issue Mar 1987...
I graduated from Chemical Eng back in 1986 but ended up doing Instrumentation Sales specializing in Control valves/PSV's with the Fisher/Emerson organization for 15 years then moved on to become a Instrument Engineer with an Engineering company for 5 years. The opportunity came & I decided to...
Good guess SeanB! Yes, this is a ALberta, Canada issue where ABSA wants us to intall a PSV on my Aerial Cooler therefore my inclination to spec a 3/4"x1" thermal on outlet tube side of the Produce Gas.
Thanks everyone for your contribution! Much appreciated!
Just to conclude I'll work backwards to see what is the highest operating pressure that the Air Cooler can see in the tubes with the HX block in. Then I'll do a Fire Gas Expansion based on this highest operating pressure although I have to...
Thanks Latexman. I did a fire gas expansion earlier with a tube surface area of 32m2 but @ 1,200 kPag the Trelief is like 1990 deg C which led me to conclude Fire case is not a credible scenario.
Thanks Latexman & dcasto for your reply.
That is correct. The MAWP for the heat exchanger is 1200 kPag. I checked for the scenario where valves are blocked and a fire broke out. In this scenario the tubes will melt before it reaches the MAWP. So I decided to spec only a 3/4"x1" thermal to...
Hi
By code I need a PSV to protect my Air Cooled heat exchanger where Produced Gas flows in the tubes. I did a Fire Gas Expansion case sizing & determine the results are not credible at Pdesign=1,200 kPag for gas composition 98% methane.
I decided to select a 3/4" x 1" thermal relief PSV with...
