Polymer Architecture Effect On Zinc Ions Stabilization In Aqueous Systems

Picture for Polymer Architecture Effect On Zinc Ions Stabilization In Aqueous Systems
Available for download

Fouling of equipment surface by unwanted materials is a well-documented problem in
industrial water systems.1 The foulants are generally classified into four categories: a)
mineral scales i.e., calcium carbonate, calcium sulfate, calcium phosphate, magnesium
hydroxide, etc., b) corrosion products i.e., iron oxide, zinc oxide, copper oxide, etc., c)
microbiological mass i.e., bacteria, algae, fungi, and other organisms, and d) deposits
i.e., clay, silt, calcium-inhibitor salts, corrosion products, etc.

The zinc ion stabilization efficacy of synthetic, biodegradable, hybrid, and natural
polymers has been studied. The results show that performance of polymers tested
strongly depends on the polymer architecture. Based on the data collected, the
performance of synthetic polymers may be ranked as follows: ter- > co- > homopolymers.
For hybrid polymers the trend is CMI-25 > CMI-15. It has also been found that among
carboxyl containing homopolymers synthetic polymers perform better than bio- and
natural polymers. The precipitate consisted mainly of zinc oxide which was predominant
at the experimental conditions, with plate like crystallites with a wide particle size
distribution. The presence of low dosage of acrylic acid homo- and terpolymers did not
have any effects on the morphology of the precipitated crystals but showed reduction in
zinc oxide particle size.

Silicon is an important element of our Planet’s crust, which is transferred into water streams through dissolution.1 Hence, it is usually found as water-soluble silicate or colloidal silica in natural surface waters (sea, rivers, lakes), or underground waters. When such water is used for industrial purposes (eg. industrial cooling), silicate can enter the operating system and can pose a threat to its proper operation. The main reason is the solubility of amorphous silica, a product of the silicate polycondensation process.

Inorganic scaling and fouling are undesirable processes occurring in process waters that are supersaturated with respect to scaling cations and anions. Mineral scaling is the result of nucleation and crystal growth phenomena that follow predictable pathways. This is because the mineral scales are composed of well-defined crystalline salts, the most common being calcium carbonate, calcium sulfate dehydrate (gypsum), metal sulfides, depending on the particular water chemistry and operational parameters (eg. temperature).

Duplex stainless steels (DSS) are an attractive alternative to conventional austenitic 300 series. They are becoming more and more present in industrial applications requiring high mechanical properties combined with good corrosion resistance.  UNS S32202 is a lean duplex grade designed to guarantee corrosion resistance superior to that of 304L in most environments and even equivalent to 316L in NaCl environment at room temperature. Its yield strength is twice as high as 304L and 316L allowing thickness and weight reduction in structural components. With low nickel content (2.5%) and no molybdenum addition, the impact of raw material price fluctuation is reduced. It makes UNS S32202 suitable for a high number of applications including public transportation, building & construction, watersystems, liquid storage and pulp&paper industry.
