why we need to compress fuel gas before sending it to the absorber column.
why only c3 is absorbed but very less amount of lighters in absorbent which is debutanier bottoms

bluewater,
If you want a reply to this, you need to provide a bit more information, so we can understand what you are talking about. Take the time to send in some pressures, temperatures, compositions, and sketch of the system, with some indication of what its purpose is.

Even without all this, I can raise this point. I don't understand why you ask why lighter components than C3 are not absorbed.Only ethane, ethylene and methane are lighter hydrocarbons than C3. Why would you try to absorb methane from fuel gas? And to absorb ethane you would need high pressure and low temperature in the absorber.
