Hi everyone!

 

We have gas condensate during gas treatment (compression system and gas dehydration), condensate returns into oil treatment system (1st and 2nd separation stage) without stabilization. 

Gas condensate consists a lot of water and light hydrocarbons such as methane, ethane, propane and butanes. This results that light hydrocarbons circulate in the oil and gas systems, gas treatment system capacity is reduced.

 

How can we decrease content of light components in condensate?

 

Thanks in advanced!

Anastasia1905, to paraphrase breizh .. to save your time and avoid misunderstanding, provide a sketch (P&ID or PFD). This is the way that Engineers work ..

Please help us help you and follow breizh's advice (which I fully endorse).

 

I'm not clear on how your process is working in terms of liquid separation. I'd expect to see 3 phase separation to take care of the hydrocarbon condensate and water phases.

 

Given that the hydrocarbons are at the light end of the spectrum, separation shouldn't be complicated by issues that can come along with heavy fractions. The key in either case is just how much shear the liquids have been subjected to upstream of the separator(s). So, I'm not seeing an obvious issue from your description as a first pass. Some further detail by way of a process schematic will probably lift a veil on the lack of understanding.

 

Is this an existing process? Or are you designing from a blank sheet of paper?

 

If the former, gaining an understanding of the liquids separation behaviour can be revealed by doing some bench tests and factoring those results into your assessment.
