Universal Continuing Decision Process For: Pumps *
| Diagrams show that as much as 50 gallons of HCl is needed to clean the ion exchange beds in a large power plant. The pump only operates periodically but must have to be large enough to deliver the cleaning agent in a short time. Also the system needs similar quantities of caustic. Electric power plants are the third largest consumer of sulfuric acid in Massachusetts. This gives some perspective on the scale. When weak acid cation exchange resins are used for dealkalization or deionization, specific sulfuric acid regenerant conditions are recommended. These are 0.7 percent concentration at a regeneration flow rate of 1.0 gpm/ft3. |
