Abstract:
To address the corrosion issues of pipelines and key
components in carbon capture, utilization and storage(CCUS) technology, this
paper delves into the corrosion pattern, forms of failure and corrosion mechanisms
of carbon steel and stainless steel while also introduces the current state of
research on the carbonation corrosion of cement and the failure of non-metallic materials. In an amine environment,
temperature, CO2 partial pressure, amine concentration, and the presence of
heat-stable salts are the
key factors influencing the corrosion behavior of metallic materials. Under the
CCUS environment with supercritical CO2, gas impurities can alter the
composition of carbon steel corrosion byproducts, accelerate corrosion and may
induce cracking. Regulating the moisture content in the gas is an important
strategy to inhibit corrosion. Stainless steel in CCUS system is susceptible to
pitting and stress corrosion cracking. The study separately examines the corrosion
patterns and the factors affecting stainless steel corrosion in supercritical
CO2 storage and liquid amine-based
carbon capture environment. Moreover, a chemical reaction between oil well
cement and CO2 can produce SiO2, which compromises cement's bonding capacity, thereby reducing its sealing
efficacy. Non-metallic
materials in service are prone to swelling and aging phenomena. Hence, their
selection should account for performance degradation due to high CO2 partial
pressures. The applicability of non-metallic
materials should be determined according to the indicators provided by GB/T
34903.1—2017 Petroleum, petrochemical and natural gas industries-Non-metallic
materials in contact with media related to oil and gas production-Part 1: Thermoplastics. The results of this study
can provide reference for material selection and corrosion control in CCUS-related facilities.
