An Efficient Scrubber

[sukishan]

From Kimre, Inc.
Horizontal crossflow scrubbers using Kimre Inc's monofilament pad material have been in successful service at a Brazilian NPK plant for 21/2 years. They are cheaper both to install and to run than normal venturi-based systems. When a conventional granulation NPK unit is required to meet rigorous emission limits for particulate material, fluorides and ammonia, it is normal to think in terms of venturi systems with the associated high power consumptions.

This article reports on the successful application of a low-energy cross-flow scrubber based on the KON-TANE and B-GON packing materials produced by Kimre Inc., or Perrine, Florida. During the 1970s, Manah SA constructed two NPK granulation plants based on Fisons technology at its Cubatao site in the state of Sao Paulo using a low-recycle solid-feeds process.

These plants had a nominal throughput of 90 t/h with product rates varying from 24 to 45 t/h, depending on the composition. They were fitted with gas cleaning equipment which was standard for that time.
