A Current Review of Polymeric Dispersants and Their Practical Significance in Industrial Water Treatment

The fouling of equipment surface by suspended matter and precipitated scale forming salts is a critical concern to water technologists and plant operators. Certain feed waters especially surface waters require far more extensive pretreatment than sources such as deep wells. Polymeric dispersants are used in water treatment formulations to control fouling of equipment surfaces. This paper will compare the performance of commercially available polymers as dispersants for a variety of suspended matter i.e. corrosion products hydroxyapatite clay silica etc. under a variety of stressed industrial water system conditions i.e. temperature high hardness high total dissolved solids presence of heavy metals surfactants coagulant/flocculant etc. Results will be presented on polymer phosphonate polymer/polymer and polymer/phosphonate blends. Additionally zeta potential data will be presented to explain the performance of different dispersants.The efficiency of test compounds towards dispersability of the different systems depends strongly on the type of interaction between the polymers with the solid surfaces and on their conformational changes at the particle-electrolyte interface.

The long-term performance of three different automotive surface coatings (physical barrier, sacrificial, and hybrid) was predicted using electrochemical impedance spectroscopy (EIS). Corrosive conditions faced by vehicles in the field, such as deicing, can be simulated using accelerated methods. The coating/metallic substrate interface experiences various degradation mechanisms during exposure to harsh conditions. In this work, real-time measurements were performed via EIS testing to characterize the degradation and corrosion mechanism of coating and substrate. After the real-time measurements, a mathematical framework based on mechanistic and machine-learning concepts was developed. Phase angle plots from EIS were utilized to monitor the state of the coating during steady-state conditions and train the Artificial Neural Network (ANN) as an arrangement of Time Series Prediction (TSP). The transport processes, activation, and interface interaction with the corrosive environments were analyzed as a corrosion mechanism and were predicted via the ANN model. The ANN has predicted the coating performance for several years, and the experimental results have been validated by employing scanning electron microscopy (SEM) imaging. Each coating condition has been validated via SEM imaging at the initial state and when the coating protection is activated.

High-temperature service places severe constraints on materials selection due to a combination of factors including the formation of oxide films, spallation and volatilization, and deterioration in mechanical properties. Materials selection is principally informed by laboratory testing under simulated conditions of temperature, thermo-mechanical fatigue, and environment chemistry (such as the presence of steam, exhaust gas chemistry, or salts). Models for predicting the high temperature performance of materials a priori are an active area for development, and are currently focused on elements such as predicting oxide formation, microstructure evolution and reduced order models for creep.

On November 4, 1993, OSHA’s Lead in Construction Standard became the law of the land.  Initially, (and to some extent today) the small residential contractor community reacted with complete outrage due to marketability fears, many claiming that they would simply stop working on “old houses.”  Industrial contractors along with the larger residential and commercial contractors often at first ignored or complied in a lackadaisical manner with these laws, continuing to work “as it’s always been done.”

In the recent years, Horizontal Directional Drilling - HDD - became a real improvement for pipeline construction when crossing obstacles such as rivers, roads or railways. For the corrosion protection of the carbon steel pipeline, a protective coating is associated with cathodic protection. But for trenchless techniques, the coating shall withstand the stresses from the installation. Several standards are used to specify corrosion protection coatings for buried pipelines but those documents do not cover the specific conditions of an HDD.

A series of accidents involving falls from or in water tanks has highlighted inadequacies in tank design and a potentially greater problem. The rescue may be more dangerous than the original accident, with the potential for more loss of life or injury.

Microbial biofilms are behind microbiologically influenced corrosion (MIC). Currently, all the so-called MIC test kits on the market are actually microbe test kits. Our new disposable miniature electrochemical biofilm/MIC test kit based on 10 ml serum vials with solid-state electrodes fills the gap to provide corrosion information such as abiotic corrosion vs. MIC, and MIC by electron-harvesting biofilms vs. MIC by corrosive metabolites. It can also test antimicrobial efficacy. An electrochemical workstation is used as a base station to perform various electrochemical scans such as linear polarization resistance, electrochemical impedance spectrometry and potentiodynamic polarization scans to provide near-real time transient corrosion data after a fluid or sludge is injected into the vial. This work presented a prototype with two different solid-state electrode choices. Three different methods to distinguish MIC from abiotic corrosion, and two different methods to distinguish MIC by electron-harvesting biofilms from MIC by corrosive metabolites. Anaerobic Desulfovibrio ferrophilus IS5 (a highly corrosive sulfate reducing bacterium) biofilm, aerobic Pseudomonas aeruginosa biofilm and an anaerobic corrosive oilfield biofilm consortium were used as examples. Tetrakis hydroxymethyl phosphonium sulfate (THPS) biocide was used as an example for assessing biocide efficacy. The patent-pending technology is currently undergoing field-testing.

Scale and corrosion inhibitors are commonly used in many oil and gas production systems to prevent inorganic deposition and to protect asset integrity. Scale inhibitor products are based on organic compounds with phosphate or carboxylic functional groups such as amino phosphonates, phosphate esters, phosphino polymers, polycarboxylate and polysulfonates,1 as shown in Figure 1. These anionic groups have strong affinity to alkaline earth cations and can adsorb on the active growth sites of scale crystal (Figure 2), resulting in stopping or delaying the scale formation process.
