Summary
This document is a technical report detailing the sour water stripping (SWS) process used in refineries to remove ammonia (NH3) and hydrogen sulfide (H2S) from sour water streams. The report outlines the sources of sour water, which primarily come from various unit operations such as distillation and catalytic cracking. It describes the centralized processing of these streams through a surge tank, heat exchanger, and stripper column. The document highlights the challenges posed by contaminants like solids and hydrocarbons that lead to fouling, resulting in reduced SWS capacity and increased maintenance costs. Additionally, it addresses the need for reliable treatment to meet production quotas and water quality specifications. The report further discusses solutions to improve refinery productivity and sulfur plant reliability by effectively removing particulate and oil contaminants, emphasizing the importance of using high-efficiency prefilters and liquid/liquid coalescers to maintain operational efficiency and safety.
