Influences of partially hydrolyzed polyacrylamide (HPAM
1. Introduction. Polymer flooding is an enhanced oil recovery (EOR) process. Water-soluble polymer, for example partially hydrolyzed polyacrylamide (HPAM), is added to the flooding water to improve the mobility ratio in the flooding process .Polymer flooding technology has been used in the later period of oil field producing.
partially hydrolyzed polyacrylamide (HPAM). The results indicated that the presence of salts and increased salinity greatly influence the apparent and plastic viscosities and water loss of bentonite suspensions with polymer. Keywords: bentonite, rheology, polymer, ionic strength 1. Introduction

In this work, the effect of partially hydrolyzed polyacrylamide (HPAM) on the oil–water interfacial properties of produced water from polymer flooding (PWPF) was investigated. In addition, this study investigated the effects of three fiocculants (polyaluminium chloride PAC, cationic polymer FO4800SH, and nonionic polymer 402) on the stability
Influence of molar mass of partially hydrolyzed
For that, partially hydrolyzed polyacrylamide (HPAM) with different molar masses were used as the EOR polymer, while the flocculant used was a Polyethylenimine (PEI), an underexplored flocculant in oil industry. HPAM was evaluated in two concentrations (100 and 1000 ppm), under two different conditions: sheared and non-sheared.
Partially hydrolyzed polyacrylamide (HPAM) is the water‐soluble polymer most often used in flooding applications in the petroleum industry. However, in aqueous solutions at high temperatures, HPAM undergoes hydrolysis of the lateral amide groups, and the presence of salts in the solution can lead to precipitation of this polymer.
The Behavior of Partially Hydrolyzed Polyacrylamide
This paper concerns one class of polymers that apparently is being tested widely as an additive for injection water; it is partially hydrolyzed polyacrylamide. The present investigation surveys some ways in which polymer solution properties are affected by polymer molecular weight, rock and fluid properties, polymer molecular weight, rock and
teristics were evaluated as a function of type and concentration of polymer (xanthan gum-XG and partially hydrolyzed polyacrylamide-PHPA) and surfactant: anionic (Blue Streak®, sodium dodecyl sulfate-SDS) and nonionic (polyoxide-based copolymer). Through characterization results (size/size distribution of microbubbles, density and air content) and

Studies have reported a positive effect of prebiotics on the bioavailability of iron. This study evaluated the effect of partially hydrolyzed guar gum (PHGG) on iron absorption mechanisms in anemic rats. Male Wistar rats were fed 75g American Institute of Nutrition Rodent Diets for growth, pregnancy and lactation (AIN93‐G) without iron for three weeks in order to induce iron deficiency anemia.

Solution properties of poly(acrylamide-co-3,5,5 - DeepDyve
The physicochemical properties of hydrophobically modified polyacrylamide (HAPAM) containing a small amount of hydrophobic groups (3,5,5-trimethylhexane methacrylate) and its partially hydrolyzed derivative (HAPAM-10N500) were investigated. The 13C spectrum was used to establish the degree of hydrolysis of HAPAM-10N500. Small-angle X-ray scattering (SAXS) was employed to highlight the
It is well-known that the amphiphilic solutes are surface-active and can accumulate at the oil−water interface. Here, we have investigated the water and a light-oil model interface by using molecular dynamic simulations. It was found that aromatics concentrated in the interfacial region, whereas the other hydrocarbons were uniformly distributed throughout the oil phase.
- What is cationic polyacrylamide?
- Cationic polyacrylamide is projected to be the fastest-growing segment during the forecast period, due to the increasing usage of cationic polyacrylamide in various applications in diverse industries, such as additives in building & construction, color removal and desalination in wastewater treatment, and cell separation in biotechnological broths.
- Which region dominates the polyacrylamide market?
- The report has analyzed the polyacrylamide market in regions, namely, Asia-Pacific, North America, Europe, Middle East & Africa, and South America. Asia-Pacific dominated the global polyacrylamide market, owing to the rising demand for polyacrylamide in this region.
- What is the key market restraint for the global polyacrylamide market?
- Key market restraint for the global polyacrylamide market is the side effects related to the polyacrylamide. The use of polyacrylamide in agriculture might contaminate the food with acrylamide, which is a carcinogen and neurotoxin. Based on type, the market is segmented into cationic, anionic, and non-ionic.
- How will the polyacrylamide market grow in Latin America & Africa?
- The polyacrylamide market will grow in Latin America due to its requirement for water treatment from developing countries. The Middle East & Africa will show development in the polyacrylamide market due to the increasing need to efficiently treat the available water in the region.
