Hydrated Lime/Slaked Lime
(Calcium Hydroxide)

Description :

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders’ lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide.

Description :

Hydrated Lime having higher percentage of Calcium Hydroxide (+90%) over low-grade (65% Purity) Hydrated Lime :

  • Reduced reaction time : The rate of chemical reaction depends upon the degree of purity of the chemical being used. Higher the purity , lesser would be the reaction time.
  • Reduced consumption : By quantitative analysis it is established that 1 m.T. Of 90% grade hydrated lime is equivalent to 1.378 m.T. Of 65% purity grade . Thus there is a reduction of 37.8% in consumption.
  • Reduced handling cost etc : By using this high purity material , handling charges inclusive manpower can be reduced by 37% due to reduction in consumption . This is a direct saving in labour cost by the same proportion.

  • Reduced transportation cost : Total transportation cost for carrying low grade (65% purity) hydrated lime = cost of carrying 65% pure material + cost of carrying 35% impure material. Total transportation cost for carrying high grade (90% purity) hydrated lime = cost of carrying 90 % pure material +cost of carrying 10% impure material. Thus it's clear that with same transportation cost 25% more pure material / utilizable material can be transported .
  • Less storage space : As there will be reduction in consumption ,less godown space would be required for storage purpose , there by, reducing storage problem & inventory cost.
  • Minimized disposal problem : Due to less consumption less sludge would be generated, resulting in reduced disposal cost.
