LIME STORAGE

AIR SEPARATOR

AIR SEPARATOR

Coarser Products

PRODUCTION

PROCESS Limestone to quicklime: -Calcium carbonate ---heat---> calcium oxide (QUICKLIME) + carbon dioxide -Chemical formula: CaCO3 ---heat---> CaO + CO2

Quicklime to slaked lime: -Calcium oxide (QUICKLIME) + water ---> calcium hydroxide (SLAKED LIME) -Chemical formula: CaO + H20 ---> Ca(OH)2

PRODUCTION

PROCESS

CaC2(s) + 2 H2O(l

Calcium Carbide reacts with water to form acetylene gas and Calcium hydroxide (slurry).

C2H2(g) + Ca(OH)2(s)

TESTING

LAB

SIEVING

DRY

SIGNIFICANCE

-Customer Requirement

-Coarser particles will choke pipelines

PROCEDURE

- Weigh out 5g of sample

- Weigh the residue left on the mesh

after 10 mins of vacumn

- Calculate the percentage passing

SAMPLE

COLLECTION

UNCONFINED PRESSURE TEST

SIEVING WET

SIGNIFICANCE

-Determine the amount of material finer than a given sieve size

-Used on adhesive/sticky soils

PROCEDURES

-Wet Sample Weighed Out -Placed on Sieve and washed down -Care taken to ensure accurate results
