The document compares the process flow for two sour water stripper designs - a preliminary proposed design and an existing design. The proposed design uses 20 sieve plate trays and achieves higher NH3 and H2S removal rates of 99.6% and 99.9%, respectively. It includes a quench feed on the 1st tray, condensor, and live steam injection on the 20th tray for reboiling. The existing design uses 26 valve plate trays, with lower removal rates of 91% for NH3 and 99.9% for H2S. It features a reflux pumparound cooler on the 7th tray, condensor, and thermosyphon reboiler on the 26th tray
