Welcome to the eProcess demonstration video on the desanding hydrocyclone.
The apparatus shown is a two inch
clear urethane.
hydrocyclone connected to a clear 35 litre.
accumulator section here at the bottom.
Together they make a desanding hydrocyclone apparatus.
In this apparatus will be flowing water
and coal particles at 12 by 20 mesh.
This is done just purely
so you can visualize the movement of the coal particles.
In this case, it takes about 75 seconds to fill the apparatus, which
includes the accumulator
and the hydrocyclone body.
A few particles are added in this case, just to make sure that the
flow is working properly and separation is occurring.
Next, we will introduce particles at a steady state, low concentration
of solids. Steady state, meaning particles, are being introduced
separated 100% separation efficiency. Reporting down through the apex
and into the accumulation section. As a particles fall from the apex
by gravity through the accumulator.
Water is displaced from the accumulator back up through the hydrocyclone
body itself.
We are having 100% separation efficiency as mentioned, and shows the normal operation of a desanding hydrocyclone
in case of like treatment separating, solids are sand from produced water.
Next, we'll demonstrate the Apex flux line, which connects the
accumulator to the overflow of the desander or hydrocyclone line
itself. Allowing water to discharge from the accumulator instead of
back up through the desander to the overflow line itself.
Introducing solids at high concentration demonstrates.
the effect of this apex flux line even more. High concentration solids
will overload or overwhelm the hydrocyclone body
Solids still being separated, but they are limited how fast they can pass through the apex
And that's they will back up into, in the desander body or the
hydrocyclone body, thus, eventually reporting to the overflow and
having zero having low separation efficiency. An apex flux line opened now
Removes that limit and allows the solids to come down quicker.
Leaving that equalization line or the apex flux line open
we can introduce a high concentration of solids at a continuous rate
and you can see the stream line flow pattern of the solids within the
hydrocyclone body.
You see, the typical Cyclone Vortex flow.
Solid particles are being introduced their passing down from the
cyclone body under separating again, 100% efficiency down through the
apex, into the accumulation chamber itself,
falling very rapidly.
And the apex flux line, allows that water to be discharged or removed
from the apex flux.
