ENZYMES FOR PAPER INDUSTRY

• Richcore Lifesciences Pvt ltd
• Bangalore

2
Enzymes
Microbial Bio-catalysts which influence the rate
of organic reactions.
3
Effect Of Enzyme Addition
4

• RICHPULP
• (Enzyme formulation for Bleach Boosting of Paper)

5
PRODUCT SPECIFICATIONS

• Chemical family Hemi-Cellulase
• Molecular weight 24 kDa
• Physical state Amber liquid
• Appearance odor Mild fermentation odor
• pH6-9.5

6
MODE OF ACTION
BLEACH BOOSTING

• Lignin or chromophores, generated during the
  Kraft cook, react with carbohydrate moieties
• Hemicellulases liberate residual lignin by
  releasing xylan-chromophore fragments, thereby
  increasing their extractability.

7
MODE OF ACTION (COTD)
8
RICHPULP ACTION
9
DOSAGE GUIDELINES

• Diluted solution of enzyme to be mixed with pulp
  at 8 10 consistency at the brown stock decker
  outlet for dispersion
• Dosage 0.3 to 0.5 kgs/ton of
  pulp
• Optimal pH 6 9.5
• Temperature 35 700C
• Residence Time 1 to 4 hours.

10
APPLICATION PROCEDURE

• Check for the last brownstock decker outlet
  volume/min
• Add Richpulp _at_ 0.3-0.5 kg/ton of pulp outflow at
  the outlet
• Min contact time of Richpulp with the pulp should
  be 1-4 hours

11
RICHPULP ADVANTAGES

• Substitution of upto 15 of the total active
  chlorine in ECF bleaching improves the
  sufficiency of ClO2.
• Higher final brightness (up to 2 ) or reduction
  in chemical consumption in TCF bleaching.
• Reduced organic chlorine levels (upto20 of AOX)
  in effluents.
• Marginal improvements (upto 5) in strength
  properties of the fibers.

12

• PROREFINE
• (Enzyme Formulation for Paper Refining)

13
PRODUCT SPECIFICATIONS

• Chemical family Cellulase
• Molecular weight 27 kDa
• Min Enzyme Activity 2600 ? 200 CMCase units/gm
• Physical state Offwhite Powder
• Appearance odor Mild fermentation odor
• pH 6.50.5

14
Mode Of Action PROREFINE
15
FIBRE PROPERTIES
16
MODE OF ACTION

• Separation Rearrangement of paper fibrils that
  enhances inter-fiber bonding
• Change in surface fibre morphology, such as
  flakes and peeling
• Selective digestion of short fibers thus
  enhancing Freeness

17
APPLICATION PROCEDURE

• Measure the pulp inflow rate/min into the
  pulper
• Dilute requisite quantity(0.5-1.5 kg/ton of
  pulp) of Prorefine with water (115 dilution)
• Add Prorefine at the batch pulpers to the
  pulp with 2-6 pulp consistency ( pHlt7.5, 45-65
  ºC).
• Pump the pulp to storage chest (total
  storage time 30-120min prior to pumping the
  stock to the refiner)
• Allow the treated pulp into refiners

18
DOSAGE GUIDELINES

• Diluted solution of enzyme to be mixed with
  pulp
• (2 6 )consistency at the batch pulper outlet
  before inflow into storage tank
• Dosage 0.5-1.5 kg/ton of
  pulp
• Optimal pH 4-7.5
• Temperature 45 65 0C
• Residence Time 30-120 min.

19
PROREFINE ADVANTAGES

• Enhances Drainage (reduced SR value by 18-20)
• Reduces refining energy load
• - 15-20 for soft wood,
• - 20-25 for hard wood
• Reduces total BOD and COD (25-30 )
• Increase in BOD / COD ratio for higher effluent
  biodegradability
• Decreased Paper-breaks
• Decreased level of Colloidal matter(resinoids) in
  the paper machine.
