Dear Colleagues,
I am designing a vaccuum destilation system for removing one volatile monomer from a latex through a steam stripping vertical column with trays.
Above the column I have included a foam trap vessel with a demister in order to avoid the foam (developed by monomer evaporation in...
Dear TiCl4,
First thank you for your useful post.
One of my available pumps is a Borger LOBE pump (not Gear) model PL-300 and probable would not have the issues described by Latexman concering weraing, but as you have noticed in your e-mail, the butadiene is very close to saturation condition...
Dear Latexman,
First, thanks for your advice. It is exactly what I would do if I had do specify a new pump, but I am trying to take one of ours available pumps to make the project feasible.
Since I have to pull the butadiene from a vessel underground, I have to consider a sel priming pump...
Dear Sirs,
I am working in a project where we will have to transfer a liquified gas (Butadiene, 3 kgf/cm2g; 30C) from a vessel bellow the sucction pump to charge a reactor that requires at least 7 kgf/cm2g at pump discharge.
I am considering to use a rotary lob pump I have available at my WWTP...
Dear Sirs/Madams,
I am a Chemical Engineering and, therefore, not the right professional to specify storage tanks for industrial aplications, but recently I have specified a process data sheet for an atmospheric tank to storage liquid fatty acids at 60 Celsius degree and choose the API-650 12th...
Dear xnuke,
First, thank you for your fast reply. Concerning your question, the transmitter is well protect against temperature, and the impulses lines are far from the heat sorce and full with cold water (condensate). Our main concern, regarding enviroment conditions, are related to vibration...
Dear Sirs,
The company where I work (rubber production industry) as a Process Engineer has two Alfa Laval Boilers MP-6.5 (6.500 kg/h)for saturated steam 170# generation fully automated with Yokogawa instrumentation, including FF communication platform. This steam generation area has been...

Dear bimr,
Thanks for your help. I also have consideres flotation would be the best option for our wastewater, but at this point I will have to consider it as my last alternative since my plant is already runing and a modification of this magnitude would require resources (money; time...
Dear bimr,
Thank you for your valueable tips. I fully agree that the inclination of bottom tunnel wall should be much great. I would have thought something lika 60o degrees (or 55 degrees as you said).
The concentration of sludge is 7.900 mg/l, and the influent must be around 600 to 1,000...
Dear Sirs,
I work at a Rubber Factory Plant that have started up a wastewater treatment plant since february´ 12.
Our worst nightmare (among small others) is the primary physical treatment where we have a rapid on line mixer to mix 200 ppm of alum with our pH adjusted raw wastewater (to pH...
Dear Friends,
Thanks for you all. Fortunatelly my bosses are not stupid (they are quite clever in fact) and accepted very well that we have no other way than building a flare. I am already quoting and it must be working by september next year.
All the posts; hints; opinions you sent me so far...
Dear Matt,
Allow me to explain my point: - I fully agree with you.
Nevertheless, I have to convince my Board (Who will have to invest a big amount of money in a flare stack) that this is the only option as you say. They were a little bit septical when I have used exactly your arguments...
Dear Chance17,
Thank you very much again for this valuable information regarding butadiene concentration limit at factory fence.
Now I can do my calculation (stack heigh) using the following three criteria:
1) 300 ppb at site fence;
2) 2 ppm at grade floor of the stack (inside the plant)...
