zdas04, We don't have this book in our library. Is it possible for you to make a scan of it when you have the opportunity.

Poli60, We don't know what the downstream application is. We just store it in spheres and bullits. We did an analysis on water content and found a watercontent of 10 and 24 ppm in 2 rundown streams, while we expected more because of the temperature of the rundowns of 23-28°C and 40-43°C...

We add methanol in order to prevent the present water from freezing. But we want to get rid of the methanol. To pass the freezing test you have to remove the water. I made some mistakes in my description: Injecting Propane should be injecting methanol.

Hello, At this moment I'm working on a project to investigate possible techniques to remove dissolved water in propane. The only thing I can find is installing a dryer with silica gel or injecting propane to reduce the freezing point. Are there other techniques applicable? Does anyone have...

bchoate, I tried to describe the condensor that is situated after the adsorbtion vessels. The purpose of the condensor is condensate steam and benzene during a steam regeneration of the adsorbtion vessels. The condensed steam and benzene is collected in a vessel underneath the condensor. When I...

To all, Thanks for your input, it made things clear to me. In my simulation I discovered another phenomenon that I can't explain. At a temperature of 69.64°C all the benzene begins to condensate. While the boilingpoint of benzene is 80.1°C. I think this decrease is caused by the "large" amount...

The air is suppleted via an air-break in the vapourline from the collection vessel. It's an existing installation which is not very sophisticated. So using N2 is not really an option. But thanks for your feedback.

For a client I'm designing a condensor (chiller) in a vapour treatment unit (adsorption by active carbon)which removes benzene from an air stream. The active carbon is regenerated with steam. The steam with desolved benzene is condensed in a condensor and catched up in a atmospheric vessel. The...

One of our clients wants to investigate the possibility of using a thermocompressor to mix two steamflow's (one superheated and one saturated at different pressure and temperature) in order to get superheated steamflow. Is it possible to simulate a Thermocompressor in ASPEN Hysis? If not, are...

Thank you both for the information

At this moment I'm working on a project in which an existing vapour recovery unit has to be redesigned. This unit catches up the benzene in a vapour stream. IT consist of 2 adsorption vessels (with activated carbon beds). In order to regenerate the carbon its washed with 125°C steam. The steam...
