Project Code: 36086

Start date and planned duration: August 2024, 18 months

Objective

Design and development of a testing system enabling dynamic testing in representative CCS environments.
Build and commissioning of a testing system enabling controlled flow of H2S, H2O, SO2, NO2, and O2 impurities.
Development of testing system to facilitate continues analytical detection and quantification of impurity concentrations, and detection of acid formation.
System shall facilitate testing of both metallic (corrosion) and non-metallic materials (ageing and degradation).

Project Outline

This CRP project seeks to develop a new capability in the form of a dynamic testing system, intended for testing of materials in representative carbon capture and storage (CCS) conditions.

The testing system will facilitate testing in controlled environments containing impurities of H2S, H2O, SO2, NO2, and O2. The capability will enable corrosion testing of metallic materials as well as general exposure testing of non-metallic materials, enabling an improved understanding of their response and degradation in controlled impurity thresholds which may result in the formation of complex acid mixtures containing HNO3 and H2SO4. The new testing facility will also enable the detection of acid formation and drop-out, thereby enabling the development of specifications for the safe transport of CO2.

Benefits to Industry

This capability aligns with TWI’s technology roadmap thereby ensuring that the needs and requirements of TWI’s members are prioritised.

The capability will enable member companies to conduct testing of materials in representative CCS environments. This will enable member companies to develop an improved understanding of the performance of both metallic and non-metallic materials, as well as their response to the formation of a secondary phase.

The capability will provide members with the ability to better understand acid drop-out and impurity thresholds at which this may occur, thereby enabling member organisations to develop specifications for the safe transport of CO2.
