Lime Parameters




Method Overview

  • Typically a grab sample from the pebble lime
  • Sampled in accordance with EPRI Method A1.

Target Compounds

  • Solids content;
  • Liquid content;
  • Calcium/Magnesium;
  • Grit
  • Weight Loss-On-Ignition
  • Available Lime Index
  • Slaking Rate

Performance Tips

Parameter Suggested Method of Analysis Description of Method Suggested Frequency Use of data
Slaking Rate EPRI Method B4 Rate of Temperature Rise Start and finish of each performance test run. Temperature rise rate is related to reactivity and lime quality
Grit (Inert Solids) EPRI Method B1 Raw lime is Slaked then sieved for grit content Start and finish of each performance test run. High grit levels indicate poor lime quality
Weight Loss-On-Ignition (LOI) EPRI Method B2 Gravimetric Start and finish of each performance test run. Weight loss is an indirect measure of lime quality via carbonate and hydroxide contents
Available Lime Index EPRI Method B3 Rapid Sugar Test Start and finish of each performance test run. Lime Quality
Calcium and Magnesium EPRI Method J1 EDTA Titration Start and finish of each performance test run. Analysis is required for processes producing a usable byproduct or high magnesium lime systems
Lime slurry solids content (% by Wt) EPRI Method F1 Gravimetric Start and finish of each performance test run. Check density meter calibration and indicate slaker performance

Shipping

  • Acetone must be shipped as a hazardous material. Please call for IATA codes if you need them.
  • Samples may be shipped at ambient temperatures (or at preservations temperatures specified by individual parameter);
  • It may prove more economical to keep acetone rinses separate, ship other samples normally, and the acetone as hazardous.
  • Be sure to include a chain of custody for each shipping container.
