Determining When to Coating Concrete

Product Number: 51220-268-SG

Author: Manuel Najar

Publication Date: 2020

$20.00

Reinforced concrete is the most common building material in water and wastewater treatment facilities. It is very common to see unprotected concrete in severely corrosive environments or corroding reinforcing steel that has been exposed due to construction defects or coating failures. The decision to coat new and existing concrete structures can be very difficult for owners due to the cost, turn-around times for putting structures back into service, and lack of confidence in certain protective coatings.

Induction Time Modeling for Common Scaling Minerals in the Absence and Presence of Inhibitors Using a Novel Theoretical Framework

Product Number: 51323-18805-SG

Author: Gaurav Das, Ronald D. Springer, Jerzy Kosinski, Andre Anderko

Publication Date: 2023

$20.00

Mineral scale deposition resulting from waterflooding processes and chemical treatment operations is one of the common issues in upstream oil and gas production. It can lead to significant flow assurance problems as scaling in the reservoirs, wellbores, well casings, oil pipelines, and other production facilities may cause considerable equipment damage and production loss while interfering with corrosion management. Scale usually deposits as a combination of different mineral phases due to the changes in solution conditions such as the saturation level, temperature, pressure, and pH.

Metal sulfide mineral scaling, fouling and deposition are frequently encountered problems in geothermal systems. Their formation, crystallization and deposition occur principally because of their extremely low solubility, based on the low solubility product (Ksp). Among the metal sulfides that cause problematic issues, the most common ones are iron sulfide (FeS), zinc sulfide (ZnS), lead sulfide (PbS), and, less frequently, antimony sulfide(s) (Sb2S3 and Sb2S5). Zinc sulfide, for example, has a Ksp of 2·10-25 mol²/L², whereas for PbS, it is 1·10-28 mol²/L² (~ three orders of magnitude less soluble). ZnS can precipitate either as Sphalerite or Zinc Blende, and PbS commonly crystallizes as Galena. Mitigation of such ZnS and PbS precipitates and deposits can be achieved by chemical interventions, by the addition of organic chemical additives to the water. Herein, we report the inhibitory effects of phosphonate-based chemical additives for ZnS and PbS scales. These additives can inhibit formation of sulfide scale, and, significantly, prevent its deposition on metal surfaces. The efficiency of these additives is dosage-dependent, and relatively high inhibitor concentrations are needed for their inhibitory activity to take place. Possible mechanisms will be discussed focusing on inhibition and dispersion.

Necessity and Challenges of Using a Float Coat for Preservation of Ballast Tanks

Product Number: 51317--9366-SG

ISBN: 9366 2017 CP

Author: John Wulterkens

Publication Date: 2017

$20.00

Traditional water treatment methods pose several challenges to large-vessel preservation. A solution to these challenges involves the application of an immiscible corrosion inhibiting oil partition on the water surface. This paper will highlight challenges of traditional preservation methods and examine the efficacy of one commercial float coat.

Author: Darrell Freeman, Ryan Horsley, David Whitt, Mel J. Esmacher

Publication Date: 2023

$20.00

In late 2021, several leaks were observed inside the waste heat boiler coil of the steam reformer furnace at the refinery. The leaks were located in the first row of tubes of the hot bank in the vertically-oriented coil, where boiler water inside the tubes is heated via waste heat of the reformer stack. The waste heat boiler coil has a design duty of 69.59 MMBtu/hr (~20.4 MW), with design pressures and temperatures of 1010 psig (6.9 MPa) and 700°F (371°C), respectively.
