help in gas processing

[coelhothiago]

I am a chemical engineering student and my final project is about a processing gas plant.
It is a DDP (Dew Point Plant). In the end of the process, there is a stabilization tower that separates two fractions, one light having C1 and C2 and other heavy with C3, C4, C5+.
The idea is to separate the C3 from the heavy stream to reuse in the refrigeration system (simple refrigeration by propane) of the plant. Today the C3 for refill the refrigeration system is bought, so we want make itself sustainable in refrigerant fluid with this adaptation.

Which would be a good layout and equipments to do that? Does someone have any tip?

Thank You

Normally the extraction plants of LNG are attached to plants of fractionation, where are extracted the c3, c4, c5+, separately, in this way could obtain part of the flow of c3 for refrigeracion,if this is not truth, could add a tower depropanizer to the process, although i do not think that is very feasible, is preferable to have a plant fractionation complete.

Although i am just a student of engineering of gas, would be good the opinion of a professional with experience.

You are right my friend, I also think isn't feaseble but is an idea to change the actual process. Just to fill some requirements of my final project. They said that had to be done something different of the actual project. Thank for the opinion. Another thing, do you have some kind of messenger? I would like to practice my spoken english with some one, if you or anybody else be intersted.

Hi, I'm a 3rd year student of chemical engineering. I'm working on a project dealing with the fractionation of free fatty acids from refined palm oil. I would be grateful if you could provide me with useful free ebooks and articles relevant to the subject. Thank you.

Hi,
I need your some info about the price of some fatty acids at 80% purity : oleic, palmitic, and stearic . Please send the info if someone have it thanks.

dear college

i agree with the opinions above but i think you could consider other uses of this component as As with ethane and other paraffin hydrocarbons, propane is an important raw material for the ethylene petrochemical industry. The decomposition of propane in hot tubes to form ethylene also yields another important product, propylene. From propylene such organic chemicals as acetone and propylene glycol are derived. The oxidation of propane to such compounds of carbon, hydrogen, and oxygen as acetaldehyde is also of commercial interest.

i hope you can find the best approach.

best regards

hi
you can use REFIRIGERATION Lean Oil absorbtion column with side product C3

Hy, I am a junior process engineer and I confront with a big problem: H2S and CO2 removal from natural gas. I simulate with Hysys but I don't know if I can trust in the results. What about PRO II simulator?Which of them do you recommend me?
Thank's a lot,
Adela.
