Dehydration of Natural Gases via High Centrifugal Force (Effect of Inlet Gas Velocity to Separation Efficiency)

This project is executed to study the effect of inlet gas velocity to separation efficiency
of removing moisture (free water) from natural gas. This experimental work had been
executed at test rig specially build for this work and using high centrifugal compact
separator. The project needs to prove that certain centrifugal equipment able to remove
99.9% moisture from natural gases. However this claim is made by hypothesis outcome
from experimental work using solid particles of< 10 microns and SF6 as the carrier gas.
There are no theoretical studies and prove regarding this matter. This project varies the
inlet gas velocity of the centrifugal separator at fixed temperature which is 35°C and
water loading 20%. The experimental work required specially fabricated compressor that
allow set up pressure range from 10 bar to 70 bar. The gas flow with desired pressure
and compressor speed (%) enters spraying system that injected fine water droplets (< 10
microns) to the gas line. Wet natural gases flow into the centrifugal compact separators
to separate free water from natural gases. Water collection will determine the separation
efficiency of the equipment based on the operating conditions. Higher pressure will
generate higher inlet velocity of gas and this willproduce higher force into the separator.
This force helps creating higher centrifugal force which improves water separation from
natural gases.
