SYNOPSIS

High corrosivity of dense-phase CO2 tends to disqualify the use of carbon steel as an economic pipeline material of choice while corrosion-resistant alloys are a few times costlier. Some of technical challenges include limited validity domain of existing CO2 corrosion prediction model, unavailability of corrosion inhibitors that could effectively reduce the uninhibited corrosion rates, uncertainty on suitable in-line inspection and online corrosion monitoring technologies and the unavailability of a prediction model to account for the minimum required fracture toughness.

The talk will highlight the technologies developed by PETRONAS that will enable the economical and safe transportation of dense-phase CO2 to sequestration sites as part of PETRONAS’ efforts towards net zero carbon emission
