Glycol injection is provided by the injection pumps with the minimum to maximum flow rates of each pump ranging 0.19 – 0.69 m3/hr according to design. The rich glycol is separated from the condensate in the Cold Separators, about 35-120 minutes retention time dependent on the EG circulation rate, this is provided for the glycol to ensure proper separation of the glycol and condensate. The glycol exits the Cold Separators, under level control and flows to the reflux coils above the packing in the still columns of the EG Re boilers where self refluxing occurs.

The rich glycol is then passed through integral lean/rich glycol coils in the surge tank section of the M.E.G Re-boilers. After being preheated by the lean M.E.G. in the accumulator the rich glycol stream flows to the
