The Urea 2000plus™ Pool Condenser process works as follows:  Ammonia and carbon dioxide are introduced to the high-pressure synthesis using a high-pressure ammonia pump and a carbon dioxide compressor.

The ammonia then drives an ejector, which conveys a carbamate solution into the Pool Condenser. The carbon dioxide feed usually originates from an associated ammonia plant, and therefore always contains hydrogen. This hydrogen is removed by catalytic combustion that uses air (Air also used to be supplied as a passivating agent to minimize corrosion in the synthesis but the advent of the Safurex® material has made this no longer necessary.)

In the high-pressure stripper, the carbon dioxide, entering the synthesis as a feed, flows counter-current to the urea solution leaving the reactor. On the shell side, the high-pressure stripper is heated with steam. The off-gas of the high-pressure stripper, containing the carbon dioxide, together with the dissociated carbamate, is then fed into the Pool Condenser.

In the Pool Condenser, ammonia and carbon dioxide are condensed to form carbamate, and a substantial part of the conversion to urea is already established here. The heat released by condensation and subsequent formation of carbamate is used to produce re-usable low-pressure steam.
After the Pool Condenser, the remaining gases and a urea-carbamate liquid enter the vertical reactor. Here, the final part of the urea conversion takes place. The urea solution then leaves the top of the reactor (via an overflow funnel) before being introduced into the high-pressure stripper.
