FLOQUIP is committed to being the industry leader in the design, fabrication, and installation of polymer storage,applications expertise into every system we offer. Our equipment is designed and
PAM usage can be significantly reduced for both conventional and ballasted flocculation if a dual polymer system is used owing to synergy between PAM and starch. The injection sequence is not a critical parameter. Therefore, a starch–PAM blend solution could be used for polymer coaddition to simplify the preparation and injection of the

automatic preparation. This type of unit (figure 19) comprises the main tank divided into a series of three tanks with overflow transfer: a first tank A, the preparation tank, receives water at a controlled pressure and flow rate, together with the powder measured out by a screw-type feeder, ensuring that the product drops evenly over the disperser; the polymer begins to swell and to dissolve
Bearing great similarities to biological systems, hydrogels with soft and wet feature have been widely explored as polymer scaffold for the engineering of man-made organs or tissues 5,6.
and fabrication of free standing PAM/PEO blend films. For the first time PAMPEO polymer matrix was pr- o-posed and chosen by us to prepare polymer blends. A simple fabrication technique was adopted for the blends preparation. Miscibility is an important property of blend system, which can affect the different properties of the blends.
The present disclosure relates to fracturing fluids that use friction reducers. The composition of the present disclosure is a slurry comprising a water-soluble polymer suspended in an oil-based vehicle with the aid of a suspension agent and a surfactant. Specifically, the water-soluble polymer is polyacrylamide and the oil-based vehicle is petroleum distillate.
Preparation and characterization of nanoparticles: The preparation of biodegradable nanoparticles was achieved by the two step method called desolvation. Gelatin type A 175 bloom: Gelatin type A (0.25 g) from porcine skin (175 Bloom Sigma-Aldrich, Steinheim, Germany) was dissolved in 25 ml water and heated below 40°C along with magnetic stirring.
Preparation of PAM-GA hydrogel magnetite nanocomposites To prepare hydrogel magnetite nanocomposites or hydrogel magnetic nanocomposites (HMNCs), PAM-GA hydrogel (“Preparation of gels”) samples were individually placed in 50 mL of doubly distilled water and allowed to swell completely over a period of 1 day. The swollen hydrogel was
3.1.1. Gelation Time. The experimental results as shown in contour and 3D response surface plots (Figure 3) indicate the relationship between gelation time, as a function of polyacrylamide and polyethylenimine concentrations.The gelation time is crucial because it is used in oilfield applications to determine the ability of PAM/PEI polymer gelant to travel deeper through the reservoir.
Background: PAM. PAM (Peptidyl-Gly alpha -amidating monooxygenase) is a dual-function, 95‑110 kDa protein that belongs to both the lyase and monooxygenase enzyme families. It is expressed in a variety of endocrine and exocrine glands and catalyzes the conversion of C‑terminal Gly into amidated residues.
Polyacrylonitrile (PAN), also known as polyvinyl cyanide and Creslan 61, is a synthetic, semicrystalline organic polymer resin, with the linear formula (C 3 H 3 N) n.Though it is thermoplastic, it does not melt under normal conditions. It degrades before melting. It melts above 300 °C if the heating rates are 50 degrees per minute or above. Almost all PAN resins are copolymers made from
A safe and efficient delivery system is critical for clinical application of siRNA. However, the conventional electrostatic interaction-based siRNA nanoplexes with bulk mixing preparation were always unsatisfactory for its stability and safety. In this study, the new core–shell lipid/PCL-PEI/siRNA nanoparticles (LPS NPs) endowing holonomic constraint of siRNA in the inner core were prepared
When used in polymer flooding for enhanced oil recovery, polyacrylamide (PAM) is an effective viscosifying agent and has been widely used for polymer flooding in oilfields in China for many years.
The crosslinking system formed strongat polymer concn. range of 3000-5000 mg/L, and the gelation time was delayed to 8-30 days, which offered the crosslinking system enough time to flow into deep water-producing zones and plug large pore paths, forcing follow-up fluids to enter low-permeability layer and reduce disproportionate permeability.
Existing reducing agents for cross-linking polymers are expensive and toxic and mostly limited for water shut off applications. A gelation study was performed on a safer, cheaper, more soluble, and short-livedby cross-linking polyacrylamide and chromium as a cross-linking agent using a rheometer and bead-pack porous media. The effect of concentration of sodium thiosulfate as the reducing
