The first set used to pump water from the river.
The second one used to pump this water to the second industrial area after chemical treatment by adding alum and lime to remove suspensions and temporary hardness.
Where water coming from the first industrial area
stored in two large basins. In this region completely removal of
hardness and suspensions in the water,getting rid of dissolved air and
then passes through the large boilers is also conducted in this
region
These
boilers are of two types:
one for water heating and the other is to produce steam.In this region
also , there are compressors with high capacity to provide sulphur
boreholes with compressed air
In this region , sulfur boreholes are found which
distributed in the field as groups ,Each group linked to control room
and a tank to collect melted sulfur out of the boreholes,then pumping
the sulfur from the tank in the field to the purification area.These
boreholes are drilled by drilling rigs with special specifications
Each borehole Consists of four overlapped pipes with different
diameters.The first pipe with the large-diameter used as coating for
the wall of the borehole, The second pipe designed to inject hot water
into the sulphur containing layer .The third pipe used as an outlet of
melted sulfur, the fourth pipe with a small diameter is to pump
compressed air to assist the melted sulfur at the bottom of the
borehole to pass through the third pipe out of the borehole
In this region,sulfur is purified from
bitumen and other impurities,by passing melted sulphur coming from the
third region through special units called (submerged combustion
reactors) .
And then to be passed through filters to come out in purified
state.Then pure sulfur to be pumped to open storage yards. where it
solidifies in the form of regular large blocks ,then it will be, by
special loading equipment ,transported out of yards using rubber
conveyor belts to the Cones of truck loading and trains.Part of
liquid pure sulfur shipped by a special train .
Iraqi sulfur specification is of high
quality and accepted in world markets .
Iraqi sulfur is exported to several countries
