SIZING OF THE DEPERICARP SYSTEM

You need to calculate the following ;

• the fibre volume
• the air required for transporting the fibre
• the separation velocity of the fibre and the nuts
• the separation column and the transport duct dimensions
• mass flow rate of air
• the selection of the fan with right volume flow rate and the choice of corresponding motor

NUTRIENT CONTENT OF EMPTY FRUIT BUNCHES

• Nitrogen (N) - 0.44
• Phosphorous (P) - 0.144
• Potassium (K) - 2.24
• Magnesium (Mg) - 0.36
• Calcium (Ca) - 0.36

# Composition as a percentage to dry matter

RATE OF EMPTY BUNCH APPLICATION

• circle mulching of newly planted and immature palms - 15 to 25 t per ha per yr
• mature palms on coastal soil - 25 to 40 t per ha per yr
• mature palm on inland soils - 35 to 70 t per ha per yr

Heat Energy Content on Unwanted Waste

• Fuel / Ratio to FFB / Energy content to total energy produced
• Fibre / 15% / 44%
• Shell / 6% / 26%
• EFB / 23% / 30%

1. Fibre @ 38% moisture @ 4700kcal/kg on dry matter
2. Shell @ 15% moisture @ 4950kcal/kg on dry matter
3. EFB @ 68% moisture @ 4200kcal/kg on dry matter

POME Extraction of Biogas

• 300,000t/year FFB, produces 5,628,000m3 of biogas
• Equivalent to 10.1304 million kwh/year
• Equivalent to approx. 50,000t CER on methane captured
• Equivalent to approx. 6,000t CER on power connection to grid

Methane Capture from POME

• Biogas CH4 ; 60-70%
• CO2 ; 30-40%
• 1 tonne POME = 28 cu m Biogas
• 1 cu m Biogas = 2 kwh

Revenue from Unwanted Waste Based on 300,000t/year FFB

• Fuel / Amount / Unit price RM / Total RM
• Fibre / 45,000t / 40 per t / 1,800,000
• Shell / 18,000t / 80 per t / 1,440,000
• EFB / 69,000 / 10 per t / 690,000
• Biogas / 10,130 kwh / 0.21 / 2,026,000
• CER / 56,000t / 34 per t / 1,904,000
• Total - RM 7,860,000

EFFECT OF HIGH FFA CPO ON OIL REFINING

The advantages that can be accrued from refining of low FFA CPO are ;

• lower refining losses of oil
• lower usage of bleaching earth
• lower dosage of phosphoric acid
• higher throughput which mean lower down time

The relationship are ;

CPO FFA CONTENT : REFINING FACTOR

<>

3 to 4% : 2.1 X % FFA

4 to 5% : 2.2 X % FFA

> 5% : 2.3 X % FFA
