Water Soluble Polymer Flocculants: Synthesis

There is no universally accepted formal definition for flocculation, but it is generally accepted that flocculation is the aggregation of solids achieved with the help of high molecular weight polymers through the formation of bridges between particles.

Acrylamide©based anionic polyelectrolytes and their

These negatively charged polymers are widely used as flocculants, rheology control agents, and adhesives. They are employed especially in oil field operations as viscosity control agents for enhanced oil recovery and to a lesser degree in engineering fluids used for lubrication, for effluent reclaiming, and for opening oil passage channels in

enhanced dewatering of oil sands tailings by a novel water

Enhanced dewatering of oil sands tailings by a novel water

This investigation introduced a new polymer flocculant for the enhanced dewatering of oil sands mature fine tailings. The monomer VBTMAC polymerizes rapidly in aqueous free radical polymerization to produce relatively high molecular weight poly (VBTMAC) that appears to be a good candidate for the flocculation of MFT.

polyacrylamide

Polyacrylamide

About 30% of polyacrylamide is used in the oil and mineral industries. [1] Flocculation [ edit] One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing.

transfer and degradation of polyacrylamide-based flocculants

Transfer and degradation of polyacrylamide-based flocculants

Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.

Influences of partially hydrolyzed polyacrylamide (HPAM

Polymer flooding technology has been used successfully in some oil field, but the produced water is more difficult to treat than that from water flooding. The influences of temperature and concentration of partially hydrolyzed polyacrylamide (HPAM) residue on the treatment of simulated oily wastewater from polymer flooding were studied in this
