what is partially hydrolyzed polyacrylamide (phpa

What is Partially Hydrolyzed Polyacrylamide (PHPA

Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.

biodegradation of partially hydrolyzed polyacrylamide

Biodegradation of partially hydrolyzed polyacrylamide

Partially hydrolyzed polyacrylamide (HPAM) in production water after polymer flooding in oil filed causes environmental problems, such as increases the difficulty in oil–water separation, degrades naturally to produce toxic acrylamide and endanger local ecosystem. Biodegradation of HPAM may be an efficient way to solve these problems.

polyacrylamide

Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.

PAM (Polyacrylamide) with its high molecular weight (> 1.0 × 10 6 g/mol) was the first thickening agent used for aqueous solutions. PAM is stable up to 90°C at normal salinity and up to 62°C at seawater salinity. Therefore, it is somewhat restricted to on-shore operations only. [5]
