RLs are susceptible to internal corrosion that is influenced mainly by fluid corrosiveness including factors such as temperature, pH, carbon dioxide (CO2) and hydrogen sulfide (H2S) content, water chemistry, flow stagnation, wettability, and presence of deposits.

Generally, for corrosion to occur there must be liquid water with sufficient quantity to wet the pipe surface. Once water wet, the line will corrode at a rate determined by the chemistry of the water, acidity and quantity of deposits.

Asset Life Extension Through Deployment of Corrosion and Inspection Technologies: Corrosion Monitoring Vs. Condition Monitoring

Product Number: 51323-19279-SG

As facilities in the oil and gas industry age with time, corrosion mitigation and control become more important. Failure of processing equipment is likely to entail production loss, loss of containment, environmental impact, and/or human risk. Internal corrosion failures represent one of the major risks to process equipment and piping.

Biocide Storage Tank Internal Corrosion And A Mitigation Strategy – A Case Study

Product Number: 51322-17906-SG

Variability of operation and practices can lead to mechanical integrity issues of equipment. A similar case was observed when an external UT survey was conducted on a biocide storage tank that showed localized areas of metal loss in the tank wall. The tank was opened for inspection and extensive internal corrosion damage was observed mainly in the form of large isolated pits. Three potential corrosion mitigation options were evaluated: upgrading the tank material from coated carbon steel to 316 stainless steel, installing a non-metallic lining, or keeping using the coated carbon steel and changing the operation practices. Each mitigation option was evaluated based integrity, feasibility, and economic factors. It was found that keeping the coated carbon steel and adjusting the operation practices can ensure the integrity of the tank while lowering the required economical investment. As such, a new operation manual was issued for the biocide storage tanks that ensured that the corrosion inducing environments are avoided.

Internal Corrosion of Flare Header - A Case Study

Product Number: 51324-21201-SG

Author: Ayman A. Alabdullatif; Lay Seong Teh; Hatam Mehraz; Anaam H. Shaikh Ali

Publication Date: 2024

In a major gas-oil separation plant (GOSP) in Saudi Arabia, a major flare header suffered from severe internal corrosion. Upon analyzing the scale and sludge that was found accumulated in the line, a significant proportion of elemental sulfur was identified. This indicated that in addition to hydrogen sulfide and water (which were expected to be present in the line), significant amount of oxygen was also present. An investigation was conducted to identify the source of this oxygen and to eliminate it. Other critical factors that impacted the internal corrosion were also identified. The line was not properly sloped to drain accumulated moisture. Knock-out boot levels were often high and not regularly drained. In addition, purge gas was not operated at rates adequate to sweep any accumulated liquids. All of these factors combined led to an accelerated deterioration of the header.

Internal Corrosion Risk Assessment for Crude Pipeline-D - A Case Study

Product Number: MECC23-19965-SG

Author: Ayman A. Alabdullatif; Rakan A. Al-Shebil; Ahmad S. Al-Otaibi; Faisal M. Al-Abbas; Omar A. Al-Saif

Publication Date: 2023

Pipeline-D was built in 1997 and was used to transport crude to Gas-Oil Separation Plant-1 (GOSP-1). The pipeline continued operating until it was subjected to intermittent shutdown in 2009 when GOSP-2 was built. As part of the project, 900 meters were added to connect Pipeline-D to GOSP-2.
