Coal Washeries :
New mining techniques result in fine coal particles. Flocculants
have been used increasingly for recovering coal from tailings as
a settling aid or by filtration/centrifugation by dewatering methods.
In addition to controlling pollution, the large quantities of water
used in washeries can be recycled using polyelectrolytes.
Brine Clarification :
Polyelectrolytes have been developed to replace the natural flocculants
once used to improve the efficiency of solids removal in the brine
circuit. These specific grades are designed to have very low levels
to metal contaminants, especially mercury.
Oil Field Services :
High performance polymers are used in all areas of the industry
– production drilling, core drilling, water shut off, mobility
control, fracturing, workovers, completions, solids removal, shale
inhibition, produced fluid treatment and in certain EOR (Enhanced
Oil Recovery) techniques such as polymer flooding.
