    Usually it is observed that after startup of unit delta P of overhead condenser increases, which limits the steam flow to the column and increases the top pressure.

    Usually ammonia and HCL vapors in the overhead gas combine to form salts which create pressure drop.  Addition of and use of water sprays into the gas stream mitigate this.  Additional sour water is recovered in the boot of the overhead accumulator.
