...Existing scale prevention technologies with polymers have been closely studied in the past. ⁵ Some low-molecular-weight polymers such as poly acrylic acid (P-AA), poly methacrylic acid (P-MAA), poly maleic acid (P-MA), copolymers of acrylic acid/acrylamide (P-AAM), and polyphosphates...

...-silicate precipitation. The present work focuses on inhibition of silica formation by examining polymeric inhibitors, that have distinctly different functional groups that may interact with soluble silica species, namely uncharged ether groups (e.g,. in polyethylene glycol polymers), neutral amide groups...

... was performed on the use of polymer-based materials or liners for large solids particle slurry applications. The study was conducted in a pilot-scale horizontal slurry flow loop using two different solids: sand and rocks. Each of the respective slurries from these particles contains some amount of the other...

.... ^{9 – 12} This kind of corrosion is also known as microbiologically influenced corrosion (MIC). ¹³ MIC is gaining more concerns since the Trans-Alaska Pipeline leak in 2006. ¹⁴ It is important to investigate whether EOR polymers can be used by microbes as organic carbons...

... not shown). Discussion on cooperative interactions responsible for soluble-silica stabilization In this work, silica stabilization results were presented on three polymeric inhibitors: neutral PEG polymers of variable molecular weight, zwitterionic poly-MHist (carboxylate groups being the anions...

... concentration under high corrosive condition. To solve the problems mentioned above, the functions of low molecular weight polymer were focused on. Low molecular weight polymer is normally used for cooling water systems to prevent scaling. New polymer which can form corrosion protection film on rusting area...

... significant quantities of tight oil; these deposits result from polymerization of dithiazines (a reaction byproduct of MEA triazine) in the presence of hydrogen sulfide. Such fouling has been reported in upstream applications. This paper highlights the effects of such fouling occurring in downstream refining...

..., and the limited performance of existing polymer chemistries in this area, creates the need for new polymeric dispersants that remain effective at controlling hardness based scales but can also control silica and iron fouling in these low pressure systems. In the later decades of the 20^th century...

Typical FRPs consist of continuous E-glass, aramid, or carbon fibers saturated with a thermoset binding resin which included polyester, polyurethane, phenolic, vinyl ester, or epoxies. Abstract Specialized polymer resins play a critical role...

...In many field applications, the lifetime of a polymeric scale squeeze can be governed by the limits of the analytical methodology used rather than the true minimum inhibitor concentration (MIC) of the polymer in the specific application. The use of improved sample preparation techniques...

.... These include water chemistry, system pH, contaminants that exert a demand for or “stress” on the polymer, temperature, water velocity, and system half-life. The late 1970’s marked the introduction of the industry’s first effective polymeric dispersant for the inhibition of calcium phosphate in high...

... and is monitored. The main chemicals coming from cooling water sources are phosphonates, azoles, heavy metals, such as zinc, and polymeric species. The limit of phosphorus and heavy metal discharge is regulated in many areas of the world and permissible limits are decreasing. Until the end of the 1980’s ¹...

...All concrete is not created equal. There are some distinct differences between polymer concrete and Portland cement concrete. These differences vary from the time it takes to achieve significant strength to each of their abilities to counter the effects of acids. Portland cement concrete strength...
