The Bripell Production System

One line produces between 12,000 to 15,000 tons per year Works with most types of biomass waste and ag residue Can effectively process biomass residues with up to 65% moisture content Low energy consumption: 150 Kva Low maintenance cost and easy to replace wearable components Automated production system

HOW TO TURN AG RESIDUES INTO A VIABLE ENERGY COMMODITY:

CORN STOVER or other crops

Burn alone or with coalTurn into cellulosic ethanol Ideal for gasification for CHP

BRIPELLS (43 lbs/ft3)

ECONOMIC CONSIDERATIONS

FEEDSTOCK REQUIREMENTS

1 Bripell plant produces between 12,000 to 15,000 MT of Bripells yearly

(higher rates with dryer material - higher the MC the more material is required ) 

FEEDSTOCK REQUIREMENTS

1 Bripell plant produces between 12,000 to 15,000 MT of Bripells yearly

(higher rates with dryer material - higher the MC the more material is required ) 

FEEDSTOCK AREA 100% Dedicated area = Approximately 50 Circles or 6,000 acres. (Realistic

Estimate around 150 to 200 Circles with an estimated 20% farmer participation)

Area production will depend on possible crop mixes. (Crop rotation with different harvest times), and also on regional factors

for different crops & outputs.

TRUCKING COSTS

Keep within a 10–15 mile radius of the plant to keep costs low

Biomass requirements

This is a function of the amount of water in the biomass. To compact correctly the biomass must have at least 8-10% MC

Biomass with a MC of 15% or lower can be fed directly into the compactor without going through the dryer.

Biomass above 65% MC can be processed but will slow production down considerably.

As a rule of thumb approximately 8-12% of the fines of the feedstock input will be burned up running the dryer.

The bripells that are produced have between 8-14% MC

ADVANTAGES OF THE BRIPELL PRODUCTION SYSTEM OVER PELLETIZING

Much more energy efficient

Bripell energy production cost @ U$4 to U$6 per ton

Pellet energy production cost @ U$9 to U$11 per ton

One production line operates on less than 150Kva-average around 120Kva x 0.6 power factor= 72Kw p/hr

No hammermill necessary as in pelletizing- shredded material is dried and directly compacted

Unique drying system uses just the biomass fines as fuel

Eliminates alot of dirt and rocks from the biomass before compacting when going through the dryer

In pelletization biomass with dirt and rocks goes directly to the hammermill, then to the pellet mill, and this excess silica leads to equipment wear and tear

The cost for bripell equipment spare parts is around U$5 per ton
