Case study of a real-world application of chemical injection quills for pipeline corrosion control

One example of a case study of a real-world application of chemical injection quills for pipeline corrosion control is the use of chemical injection quills in a natural gas pipeline in North Dakota. The pipeline was experiencing corrosion due to the presence of hydrogen sulfide (H2S) in the natural gas. To control the corrosion, inhibitors were injected into the pipeline using chemical injection quills.

The pipeline operators chose to use a specific corrosion inhibitor that was known to be effective in controlling corrosion caused by H2S. The inhibitor was injected at a controlled rate using chemical metering pumps that were connected to the chemical injection quills. The quills were inserted into the pipeline at strategic locations and were equipped with flow control valves to ensure accurate and precise chemical injection.

The results of the case study showed that the use of chemical injection quills and corrosion inhibitors was effective in controlling the corrosion caused by H2S. The pipeline operators reported a significant reduction in corrosion and an increase in the lifespan of the pipeline. Additionally, the use of chemical injection quills and inhibitors helped to reduce maintenance costs and improve the overall efficiency of the pipeline.

This case study demonstrates how chemical injection quills can be used effectively in real-world applications to control pipeline corrosion. By injecting inhibitors at the right place, flow rate and time, it’s possible to reduce the corrosion rate, extend the life of the pipeline and ultimately save on maintenance costs. It also shows how a specific inhibitor can be used to address a specific type of corrosion, in this case caused by H2S.

How does the above case study compare to traditional methods of pipeline corrosion control?

This case study of using chemical injection quills for pipeline corrosion control in a natural gas pipeline in North Dakota compares favorably to traditional methods of pipeline corrosion control in several ways:

  1. Efficiency: Traditional methods of pipeline corrosion control, such as cathodic protection, can be time-consuming and labor-intensive. The use of chemical injection quills allows for a more efficient and precise application of corrosion inhibitors, reducing the amount of time and resources required to control corrosion.
  2. Cost-effectiveness: Traditional methods of pipeline corrosion control, such as coatings, can be expensive and require regular maintenance. The use of chemical injection quills and inhibitors is a more cost-effective solution, as it reduces the need for regular maintenance and repairs.
  3. Safety: Traditional methods of pipeline corrosion control, such as acid cleaning, can be dangerous and pose a risk to workers. The use of chemical injection quills and inhibitors is a safer solution, as it reduces the need for manual intervention in the pipeline.
  4. Flexibility: Traditional methods of pipeline corrosion control, such as cathodic protection, may not be suitable for all types of corrosion or pipelines. The use of chemical injection quills and inhibitors provides a more flexible solution, as different inhibitors can be used to address different types of corrosion.
  5. Environmental impact: Traditional methods of pipeline corrosion control, such as acid cleaning, can have negative environmental impacts. The use of chemical injection quills and inhibitors is a more environmentally friendly solution, as it reduces the amount of chemicals used and minimizes the risk of spills and leaks.

In summary, this case study of using chemical injection quills for pipeline corrosion control in a natural gas pipeline in North Dakota illustrates how chemical injection quills are more efficient, cost-effective, safe and flexible than traditional methods, such as cathodic protection, coatings, acid cleaning and others. Additionally, chemical injection quills are more environmentally friendly as they can minimize the chemical usage and spills.

Summary of results and benefits achieved in the case study

In the case study of the natural gas pipeline in North Dakota, the results and benefits achieved by using chemical injection quills for pipeline corrosion control were substantial. The pipeline experienced corrosion due to the presence of hydrogen sulfide (H2S) in the natural gas, and inhibitors were injected into the pipeline using chemical injection quills to control the corrosion.

The results of the case study showed that the use of chemical injection quills and corrosion inhibitors was effective in controlling the corrosion caused by H2S. Specifically, the pipeline operators reported:

  1. A significant reduction in corrosion: The corrosion rate in the pipeline was significantly reduced, which extended the lifespan of the pipeline and reduced the need for maintenance and repairs.
  2. Increased efficiency: The use of chemical injection quills and inhibitors improved the overall efficiency of the pipeline, as the precise and accurate injection of the inhibitors reduced the need for manual intervention and minimized downtime.
  3. Cost savings: The use of chemical injection quills and inhibitors resulted in cost savings, as it reduced the need for regular maintenance and repairs, and eliminated the need for expensive coatings or cathodic protection systems.
  4. Improved safety: The use of chemical injection quills and inhibitors improved safety, as it reduced the need for manual intervention in the pipeline, minimized the risk of spills and leaks, and eliminated the need for dangerous acid cleaning methods.
  5. Environmental benefits: The use of chemical injection quills and inhibitors resulted in environmental benefits, as it reduced the amount of chemicals used and minimized the risk of spills and leaks.

In summary, the case study of the natural gas pipeline in North Dakota demonstrates that chemical injection quills can be an effective method for controlling pipeline corrosion. By using chemical injection quills and inhibitors, pipeline operators were able to reduce corrosion, increase efficiency, save costs, improve safety, and reduce the environmental impact. This case study is an example of how chemical injection quills can be used effectively in real-world applications to address specific corrosion issues and extend the life of the pipeline.
