Patent #01

  • A Process for Preparing low Silica CaO by State of art vertical lime Kiln.

  • CaO is very important Gradient for paper industry. It consumes 500 kg CaO to produce 01Mt Paper.

  •  Main Raw material for CaO is CaCO3 Calcium carbonate to get a high purity CaO one must have high purity of CaO3.

  • Theoretcal energy requirment to produce 80% purity CaO is 2.6 GJ/M . In Paper industry this energy requirment goes as high as 12 GJ/Mt for recycling lime Sludeg.

  • By this patent Process someone can be able to get 80% purity lime by consuming only 4.5 GJ/Mt energy.

  • In this process we desilicate lime sludge and then sludge under goes for pelletization.

  • Pellet undergoes for natural sun dry process.

  • Finally are fed to state of art vertical lime kiln.

Patent #02

  • Two Way Feedding and condensate sealing system to increase individual effect overall heat transfer coefficient in Multiple Effect Evaporation Plant.

  • Get your water evaporation capacity atleast 1.5 times more without adding any new heating surface area.

  • Get steam Consumption as low as 140 kg/Mt water evporation in 8 Effect evaporation plant .

  • Steam economy as high as 7.3 MT/MT

  • Solids as high as 85%

Patent #03

  • A Processfor weak black liquor conditioning for scale minimization in kraft MEEs

  • This is a four stage wet washing of  raw materials like wheat straw, Bagasse, rice straw and wood chips.

  • Chloride content has been reduced by 90%.

  • Silica in treated material reduced by 75%.

  • Calcium and magnesium ions has been reduced by 99%

  • Ash content has been reduced by 85% from raw material.

  • Black liquor solids generation reduced by 20%.

  • Black liquor GCV improved

  • reduced load of CD in pulp mill.

  • lesser silica in pulp means more speed of Paper machine (Drainage improved).

  • reduced bleaching cost.

  • Zero dischage from wet washing to ETP
