SYNOPSIS

Top of line corrosion (TLC) in CO2 wet gas pipeline is a major threat to oil and gas industry,where difference in temperature of internal pipeline and outside environment leads to condensation of water in a stratified flow regime. This condensed water is corrosive to pipelines’ surface containing organic acids and dissolved acidic gases such as CO2 and H2S. In oil and gas field, gas condensate is usually present in the pipeline. However, only gas condensate-free TLC systems were usually studied. This condensable hydrocarbon may affect condensation process as it is immiscible with water which leads to different wett ability on pipeline surface. On top of that, the control and monitoring of TLC is challenging to pipeline operators since it requires corrosion inhibitor with volatile properties to reach the upper part of pipe. Typically, conventional corrosion inhibitor is applied to mitigate corrosion by deploying itvia continuous injection or batch treatments. Such inhibitor functions by forming a protective film or layer on the steel surface which consequently contribute to the reduction of corrosion.However, the method is only feasible for bottom-of-line corrosion (BLC) because the inhibitor is normally not volatile and are absent at the top-of-line unless they are physically transported there by droplet transport or non-stratified flow. In order to mitigate both bottom-of-line and top-of-line corrosion, volatile corrosion inhibitor (VCI) needs to be applied. However, the technology development of VCI is still low in Malaysia as most of the product are made from international company. This was due to the lack of knowledge and technology in TLC specifically in VCI testing in Malaysia. However, InCORE UiTM is the pioneer in TLC and VCI R&D where volatile and non-volatile corrosion inhibitor are our main focus of development since the technology was successfully transferred from USA since 2015.

1) Michelle Lau

Michelle Lau is a NACE International Cathodic Protection Specialist and she is serving as the Managing Director at Mach3 Engineering Sdn. Bhd., a role which she has held since its inception.

Her career is in the field of Cathodic Protection for the Oil and Gas, Power Generation and Water Utility industry. She has experience in handling various projects around the Asia Pacific region which includes developing design specifications, performing inspections and audits for cross country pipelines, storage tanks, plant piping, marine structures, intake and offshore structures. She is also one of the very few certified Cathodic Protection Specialist in Malaysia.

Apart from that, she has been invited to give technical presentations on the awareness of corrosion, cathodic protection and corrosion control at many international conferences and corrosion management workshops.Her passion and tireless contribution is in combating corrosion as well as advocating female participation and contribution in the engineering fraternity.

Despite her busy work life, she is actively involved in both local and international engineering associations asa voice of the industry. Presently, Michelle is on the Board of Directors of the Association for Materials Protection and Performance (AMPP); prior to this, she served as the NACE International Institute Vice President, and NACE International East Asia and Pacific Area Director. As a staunch believer in coaching and grooming youth to the industry, Michelle was appointed to the Industrial Advisory Panel for Materials Engineering Programme at University Science Malaysia. She is also actively guiding undergraduates inorganising activities to create awareness of corrosion prevention.
