Casing Corrosion in Geothermal Environments Containing Sulfuric Acid

Product Number: 51324-20932-SG

Author: Joseph Thevakumar; Joshua Owen; Richard Barker; Evgeny Barmatov

Publication Date: 2024

$40.00

This work focusses on understanding corrosion severity and material performance within model geothermal sulfuric acid (H2SO4)-containing environments. With the use of a tantalum-lined high pressure/high temperature autoclave, the corrosion behavior of N80 carbon steel was compared against duplex stainless steel when exposed to H2SO4 solutions (pH 2-4) at temperatures up to 150°C. Electrochemical linear polarization resistance measurements were implemented to gather real time corrosion kinetic data. Complimentary ex-situ analyses (scanning electron microscopy and white light interferometry) were conducted to understand the corrosion mechanism and quantify localized corrosion rates. A quantitative relationship was identified in terms of pH, temperature and metal corrosion for the selected materials to highlight material capability within such low pH geothermal environments.

Nga Awa Purua geothermal power station (NAP) operates a conventional direct contact condenser with recirculating cooling water and forced air cooling towers. The power station is located at the Rotokawa Geothermal field, near Taupō in the North Island of New Zealand. The field supports two power stations: NAP, which was commissioned in 2010 with an installed capacity of 140 MW; and Rotokawa I, a binary power plant which has been in operation since 1997.

Several components in geothermal power plants need to be protected from the environment due to the corrosive nature of geothermal fluids used to generate the energy. Depending on the fluid properties for any location, the type of protection varies. In geothermal power plants, wear, erosion, corrosion, and scaling are all known problems1. These issues can lead to a variety of outcomes, ranging from decreased plant efficiency to upstream component failure. Failure of a component is thus a significant challenge in the geothermal industry, where materials need to operate in high temperature and high pressure environments. A major cost factor is also linked to the drilling of geothermal wells, where cost rises due to increased depth/distance of drilling, increased trip times, higher high temperature and high-pressure conditions which can lead to increased wear and corrosion of the materials. To address the issue, coatings can be considered to be a potential solution to extend the service life of downhole equipment.
