HCl Control With Dry Injection Of Sodium Bicarbonate Or Trona
By J.P. Balland, Solvay S.A., Yougen Kong, Michael Wood, SOLVAir Solutions, Solvay Chemicals, Inc.
Recently presented at the International Air Quality VIII Conference in Arlington, VA, "HCl Control with Dry Injection of Sodium Bicarbonate or Trona" reviews US emission limits for current boiler MACT and proposed utility MACT, and examines a case study on municipal solid waste incineration (MSWI) in Europe and at a power plant in the United States. Physical and chemical properties of SOLVAir sorbents, their processing and way of use are also reviewed, as is acid gas mitigation chemistry. Guidelines to design dry injection of SOLVAir sorbents are also included. In conclusion, DSI of sodium bicarbonate or trona is shown to be a cost effective way to mitigate HCl within the framework of new boiler MACTs, with very high mitigation possible for HCl (>99%, already achieved in EU facilities.)
