Brass alloys are considered corrosion-resistant in potable water. However, chloride, disinfectants, and high flow rates were reported to weaken pipes, leading to leaks and damage. The degradation of copper alloys causes concern as metal ion release may affect water taste and human health in high concentrations. Therefore, materials with improved flow corrosion properties and increased corrosion resistance are needed. Failure investigations were performed on C52100 brass domestic water flowmeters by visual inspection, microstructural analysis with scanning electron microscope energy dispersive X-ray spectroscopy (SEM-EDS), and X-ray diffraction (XRD). The failure is mostly initiated by high local flow rates causing erosion corrosion attacks with dezincification. The corrosion behavior of C52100 (phosphor bronze), C89520 (Se-Bi brass), and S31600 (stainless steel) was investigated and compared to C27453 (brass) in drinking water with varying contents of chloride, ammonia, and chlorine by potentiodynamic polarization curves and long-term immersion tests. Furthermore, flowmeters (made of C27453 and C89520) were installed in a flow test setup to investigate flow induced conditions in a laboratory environment with aggressive drinking water. Immersion tests, flow tests, and potentiodynamic investigations show that brass corrodes at a higher rate than bronze, Se-Bi brass, and stainless steel in such environments.

The unstable oil market demand in the petroleum industry, the oil financial crisis and the Covid-19 pandemic have pushed the Oil and Gas operators to look for optimized, cost effective and more reliable strategies of design and operation. Large part of CAPEX is invested in the well materials. Hence, materials of Oil and Gas wells should be selected to withstand both internal and external threats to ensure integrity and availability while maintaining on focus on affordability over the lifecycle.¹

Corrosion issues in the conversion of vegetable and waste oils to produce biofuels

Product Number: 51323-19308-SG

Author: Fouad Andari, Jean Kittel, François Ropital, Joana Fernandes, Laure Dodelin

Publication Date: 2023

$20.00

To limit the impact of greenhouse gas emissions on climate change, the use of conventional hydrocarbons needs to be reduced significantly. The global demand for biofuels is thus expected to grow during the present decade. Hydrogenated Vegetable Oil (HVO) is one of the predominant biofuels produced by converting lipidic feedstocks (vegetable oils, animal fats, waste cooking oils, …) through a conventional refinery hydrotreatment (HDT) process.

Project A is being developed by the company with two fields about 220 km distance from Bintulu, Sarawak. The fields are classified as sour with estimated H2S concentration up to 5,000 ppm and 3.8 mol% CO2. The two fields are mainly Field A1 and Field A2 with approximately 20km apart. Field A1 will have two dry xmas trees, drilled from the Platform A while Field A2 will be developed with 2 subsea wells and supporting subsea infrastructures.

Corrosion Management Improvements in Liquids-Rich Shale Play - Pipeline Internal Corrosion Mitigation Case Studies

Product Number: 51324-20990-SG

Author: Monica Fernandez; Chris Jeske; Robert Terry; Ruben Carrera

Publication Date: 2024

$40.00

This paper details the process followed to enhance the pipeline internal corrosion management during operational stage in a liquids-rich shale play, focusing on pipeline internal corrosion mitigation. The process involves several key steps, encompassing a thorough review of historical data (operational conditions, fluid chemistry, corrosion coupons, chemical treatments, pigging activities, inspection results, among others), meticulous data analysis, strategic scheduling, implementation of short-term, mid-term, and long-term actions, followed by periodic monitoring to evaluate barrier performance in conjunction with an inspection plan to confirm asset integrity and optimize resource utilization. The improvements have considered industry best practices, know-how, lessons learned, valuable insights gained from past failures, challenges encountered within upstream operations for corrosion and integrity activities execution, and the actions taken to overcome them.

Corrosion Management in Hydrocracking and Hydroprocessing Units

Product Number: MPWT19-14442

Author: Hendrik J. Debruyn

Publication Date: 2019

$0.00

Hydrocracking and other refinery hydroprocessing units have a common goal to convert organic sulfur compounds to hydrogen sulfide (H2S) that can be removed, thereby producing low-sulfur refinery products. Corrosion and equipment degradation risks range from high-temperature hydrogen attacks (HTHA) to ammonium bisulfide and ammonium chloride corrosion in the downstream heat recovery and fluid separation equipment.
This paper provides an overview of corrosion management principles that can be applied to reduce operating risks in new and existing units, focusing equipment susceptible to ammonium bisulfide (NH4HS) and ammonium chloride (NH4Cl) corrosion. Best practices for materials selection, as well as designing for corrosion management through adequate provision of corrosion management related instrumentation and sampling points are covered.

Corrosion Management Learnings For Atmospheric Storage Tanks

Product Number: 51322-17951-SG

Author: Gulnur Badalova, Mikael Johansson

Publication Date: 2022

$20.00

The terminal is subdivided for Oil, Gas and Produced Water plants. Each of these plants has number of storage tanks. The age of the tanks varies between 15-25 years. The products held within these tanks varies, from crude oil, condensate, produced water, potable water, to off spec oil and diesel fuel.

Most of the tanks within the facility have a similar CP arrangement and design. Each tank base is protected by an impressed current grid mesh anode buried in compacted, clean, sand backfill beneath the tank base and is powered by a transformer-rectifier placed outside the bund wall or within an electrical switch room. Permanent reference electrodes are installed beneath all tank bases to enable accurate potential measurements. Reference electrodes vary from Copper/Copper Sulphate, Silver/Silver Chloride to Zinc.

Corrosion Mechanisms Of Mild Steel In The Presence Of Formic And Acetic Acids

Product Number: 51322-17944-SG

Publication Date: 2022

Corrosion is a surface phenomenon, which is defined as the deterioration of a material due to chemical and/ or electrochemical reactions. The continued interest in understanding corrosion phenomena and devising mitigation methods stems from the potential influence corrosion has on infrastructural damage across diverse industries. The most prevalent forms of corrosion encountered in the oil and gas industry are referred to as sweet and sour, corresponding to aqueous CO₂ and H₂S environments, respectively. The presence of an aqueous phase in these environments leads to the formation of a weak acid which is understood to be detrimental to the service life of carbon steel pipelines, when not properly mitigated.
