Kostnad för uppgradering
Cost for up grading
Our estimation for BioSling and
1000 cow is 0,18 €/nm3
Raw gas from
1000 cows ≈70nm3/h

a)
b) Coil pump, circulates a liquid for gas absorption.The
pump is partially submerged in a trough filled with
absorption liquid. The mouth of the coil is
alternating in the atmosphere or in the liquid by
rotation. Rotation creates alternating scoops of liquid
and gas, which are screwed to the right. The gas is
compressed and absorbed accordance to Henry´s law.
The liquid is selected to selectively absorb carbon
dioxide, the basic principle for gas separation.
c) Vessel accumulating methane and diverting liquid
with absorbed carbon dioxide. The pump generates a
gas pressure of a few Bars.
d) V1, a throttle valve depressurizes the liquid .
Bubbles of methane
and carbon dioxide
e) "flashtank" is an atmospheric vessel for releasing the
carbon dioxide . The vessel is also buffer volume for
the absorbent .
f) V2, a control valve for the liquid level in the trough.
Manure + urine + organic substrate +
bacteria for anaerobic digestion
g) F1, this float controls the liquid level and stops gas
from escaping .
