Sour Water Stripping Unit - Refinery Distillation

Dec 20, 2020 · The water is pumped to steam stripper column V-103, with about 40 sieve plates. Ammonia and H2S are stripped from this water in column V-103, with 40 plates. The column has a thermosyphon reboiler E-104, heated with 150psig steam. Feed before entering the column is heated to approximately 205°F by heat exchange with the V-103 bottom stream in

May 11, 2021 · Heggs and Alane 20 reported a circulation ratio of 100 kg circ kg feed −1 at a system pressure of 200 mbar and a heat flux of 12 kW m −2 for the boiling of water in a thermosiphon reboiler. Their maximum circulation ratio in the measurement range was 245 kg circ kg feed −1. It should be noted that deviations due to flash evaporation in

Steam strippers allow for the removal of heavy soluble organic compounds that air strippers cannot remove. The temperature of these columns is usually very close to the boiling point of water. In a typical steam stripping column, the liquid feed is introduced at the top of the column and the steam input is located at the bottom.

The sizing of a sour water stripper is very important since its capacity must equal or exceed the normal production rates of sour water from multiple sources in the

For reliable design and operation, the vapor weight fraction in thermosyphon reboilers should be limited to about 25–30% for organic compounds and about 10% for water and aqueous solutions [ 1, 2 ]. If these limits cannot be attained with once-through operation, then a recirculating system should be used.

The sour water stripper reboiler supplies heat to the stripper to strip the H 2 S and NH 3 from the sour water. This reboiler is supplied with a low-pressure (LP) saturated steam as a heating medium. The overhead acid gas from the top of the stripper is then sent to the SRU. Fig. 1 shows the Stripper 1 simulation. The package selected for this
