Polyacrylates - an overview | ScienceDirect Topics
Dry Strength Additives. Polyacrylamides (PAMs) are used to increase the dry strength of papers by hydrogen bonding. PAM of molecular weight of 100,000 to 500,000 is used at about 0.5% on pulp and also acts as a retention aid. It is sometimes used to allow increased use of lower quality pulps such as secondary and hardwood fiber.
Its effect is that it is mainly used in tertiary oil recovery of oil fields in the aspect oil production, and raw oil of about 100 to 150ton more can be produced through filling the macromolecule polyacrylamide product one ton.
US4617359A - High molecular weight polyacrylamide
This invention discloses a process for the polymerization of acrylamide and for the copolymerization of acrylamide with other monomers. It employs a ferrous/hydroperoxide redox initiator system that greatly enhances the molecular weight of the polymer formed. These high molecular weight acrylamide polymers offer outstanding advantages in enhanced oil recovery as injection water viscosifiers.
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction

Synthesis and Characterization of Different Molecular
will increase the molecular weight of the resulting polyacrylamide. Thus, under nitrogen atmosphere 15, 30 and 50 gm of acrylamide monomer were polymerized in (500ml) distilled water as a solvent and the (0.135gm) potassium persulfate/(180μl) TEMDA system as initiator to produce medium, high and very high molecular weight polyacrylamides respectively.
Polyacrylamide(PAM), often referred to as “polymer” or “flocculant”. It is a long chain, linear organic polymer made up of individual monomer units with the molecular formula of C3H5NO and molecular weights ranging from 3,000,000 to 30,000,000 Daltons. PAM is a dry white or light yellow powder similar in shape to table salt.
Polyacrylamide Market Size, Share & Growth | Industry
Polyacrylamide (PAM) is a synthetic, potassium based long-chain polymer. It has a high-molecular weight and is a kind of water-soluble polymer, that is produced through polymerization of acrylamide. The global polyacrylamide market will grow at an impressive rate owing to its increasing use mainly in petroleum and wastewater sector.
The kinematic viscosity of Iraqi crude oil was calculated according to ASTM D-445, while specific gravity was according to ASTM D 1217-81. 2.2. Drag reduction agent. Polyacrylamide (PAM) is a versatile family of synthetic polymers used worldwide and high infinitely soluble in water. It is white dry solid form with molecular weight of 3 × 10 6

Refinery waste water: The specification of refinery waste water samples which was taken from the Al-Samawa oil refinery was determined in the laboratory of Al-samawa oil field at
- How is produced water treated?
- Mature and robust technology for produced water treatment and disposal. Treatment is carried out through freezing, thawing and evaporation. Efficient in arid environments with regular subfreezing temperatures ( Sorensen et al., 2002 ).The FTE process requires minimal pre-treatment of produced water.
- Which chemical agents are used for PW treatment on offshore platforms?
- Chemical agents for PW treatment on offshore platforms. Water stabilization agents, such as bactericides, descaling agents, and corrosion inhibitors, are used to ensure the stability of the system ( Li et al., 2010; Wu and Yang, 2004; Zheng, 2003; Jang et al., 2017 ).
- Why is PW treatment important for offshore oil & gas fields?
- The capacity of PW treatment would be the one of the most significant factors that can restrict the deliverability of offshore oil and gas fields as the strictness of marine environment protection standards and water content of produced liquid continue to increase.
- What is a realistic treatment process for oil & gas?
- Physical devices coupled with chemical agents are the realistic treatment process. Offshore oil and gas production is increasingly growing popular globally. Produced water (PW), which is the largest byproduct of oil and gas production, is a complex mixture of dissolved and undissolved organic and inorganic substances.
