Scrubbers for phosphoric acid plants (Journal Article)

The basic considerations in selecting a scrubber for large phosphoric acid plants are 1) whether they can meet process requirements and environmental standards, 2) reliability and ease of operation, and 3) capital and operating costs. Heat and material balance work will establish the flows, composition, and temperatures for the basic design.
