What is non sour service?
On the other hand non sour services are those which do not include this harmful substance. Examples include, Vallourec which offers a large range of OCTG High Collapse grades, specifically to meet the most challenging collapse conditions of well-environment as well as load cases scenarios.
What is wet sour service?
Wet H2S service is referred in a process stream where both water in liquid phase and H2S are present. Carbon steel is commonly use in this environment, but it can be subject to degradation depending upon pH, H2S level, temperature, duration of exposure and nature of the material.
What is a sour gas well?
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide (H2S). Natural gas typically contains several ppm of volatile sulfur compounds, but gas from one well in Canada is known to contain 90% hydrogen sulfide and others may have H2S contents in the tens of percent range.
What is sour line?
Sour service describes a type of pipeline or storage vessel that is filled with substances that contain hydrogen sulfide (H2S) or sulfuric acid (H2SO4). In order for the service to be considered a sour service, the hydrogen sulfide levels must be above a certain threshold.
What is NACE material?
NACE MR0175, is titled Petroleum and natural gas industries — Materials for use in H2S-containing environments in oil and gas production. It was issued as a recommendation of threshold limits of H2S above which precautions against environmental cracking are considered necessary.
What is difference between NACE MR0175 and MR0103?
NACE MR0175 applies to upstream exploration and production operations, NACE MR0103 is specific for refinery environments. Both standards provide specific requirements for different metallic materials like carbon and low alloy steels, stainless steels, nickel alloys and other metallic materials.
What is sour service NACE?
The definition of sour service used in the standard is: “Exposure to oilfield environments that. contain sufficient H. 2. S to cause cracking of materials by the mechanisms addressed by NACE MR0175/ISO 15156.” This definition addresses both the sensitivity of all metallic materials, including carbon and low-
How do I get rid of sour gas?
The only thing that can be done with Sour gas is to cool it. When cooled to -163.5 °C; 67% of its mass becomes Methane and 33% becomes Sulfur.
What is the difference between sweet gas and sour gas?
The key difference between sweet and sour natural gas is that the sweet natural gas contains trace amounts of hydrogen sulfide, whereas the sour natural gas contains large amounts of hydrogen sulfide. Moreover, sweet natural gas is non-corrosive, less acidic, and requires little refining.
How do you cure sour gas?
Sour gas treatment involves using amine solutions to remove acid gases such as hydrogen sulfide (H2S) and carbon dioxide (CO2) from hydrocarbon gas in refineries and gas plants.
What does NACE stand for?
National Association of Corrosion Engineers
The National Association of Corrosion Engineers (NACE) is an organization serving nearly 35,000 members in 130 countries, and recognized globally as one of the premier authorities for corrosion control solutions.
What’s the difference between sour service and non sour service?
Sour service can be defined as a situation where in the environment there exists Hydrogen Sulfide (H2S). This substance present in the environment is hazardous to the human health. It could also significantly impact steel drilling tubulars performances in service operations as well.
Why is sour service important in the oil and gas industry?
Sour service is a major concern for the oil and gas and wastewater industries. Bacteria in the product collected during the extraction process in the oil and gas industry mixed with high amounts of sulfates can result in a sour service condition. This same risk exists frequently in the wastewater industry as well.
What makes a vessel a ” sour service “?
Sour service describes a type of pipeline or storage vessel that is filled with substances that contain hydrogen sulfide (H 2 S) or sulfuric acid (H 2 SO 4). In order for the service to be considered a sour service, the hydrogen sulfide levels must be above a certain threshold. Sour service can subject the vessel material to corrosion.
Which is the best definition of sour service pipe?
1. Sour Service Pipe Definition. Sour service pipe mainly used in H2S environment. While H2S is a harmful chemicals that mostly easy to generate the corrosion. According International regulation: When partial pressure of H2S reaches 300 pa, the line pipes used shall have the anti-acid corrosion performance.Sour service pipe includes NACE pipe.

How does sulfuric acid lead to sour service?
The sulfuric acid can then lead to corrosion. Sour service is a major concern for the oil and gas and wastewater industries. Bacteria in the product collected during the extraction process in the oil and gas industry mixed with high amounts of sulfates can result in a sour service condition.
