Guideline To Determine Erosional Velocity For Liquid Hydrocarbon Transmission Pipelines

Picture for Guideline To Determine Erosional Velocity For Liquid Hydrocarbon Transmission Pipelines
Available for download

Erosion is a major threat to liquid hydrocarbon transmission pipeline integrity when high liquid flow ratesare combined with the presence of solid particles. However, there is currently no generally acceptedguidance document or standard by which liquid petroleum pipeline operators can define maximum allowable velocities to manage the threat of erosion in their pipelines.

EErosion can be a major threat to liquid hydrocarbon transmission pipeline integrity if high liquid flow rates are combined with the presence of solid particles. Erosion may cause metal loss to the pipeline and in extreme cases lead to pipeline failure. 

There is currently no industry-recognized guidance document or standard for determining erosional velocity limits for liquid hydrocarbon transmission pipelines. Many operators use the general form of the American Petroleum Institute RP 14E equation to determine erosional velocity, but it does not properly address the effect of the key parameters affecting erosion in liquid pipelines and could give erroneous results in some cases. 

This paper presents a guideline to determine erosional velocity limits for liquid hydrocarbon transmission pipelines, developed based on a multi-analytical probabilistic approach that integrated results from two industry-recognized erosion prediction models.

The guidance developed allows pipeline operators to reduce capital costs when designing new pipelines or can provide engineering justification for increasing the throughput of existing facilities while maintaining pipeline integrity relative to the threat of erosion.

The impact of corrosion on society is enormous. The National Association of Corrosion Engineers (NACE) estimated that the global total cost of corrosion is ~$2.5 trillion (USD), approximately 3.4% of global GDP.1 In 2016, NACE released the “International Measures of Prevention, Applications, and Economics of Corrosion Technology” which estimates that implementing corrosion prevention best General Business practices could result in global savings between 13-15 percent of the cost of damage, or a savings between $375-875 billion (USD) annually on a global basis.

The formation of mineral scales is one of the most problematic threats to the oil and gas operations which can lead to loss of production, increased lifting costs and assets deterioration.1 Mineral scales can precipitate at any locations within an oil and gas production system and create blockage in perforations, production tubulars, pumps, and surface equipment. The formation of scale deposits can be attributed to the mixing of incompatible waters from different production zones or physical and chemical condition changes associated with produced water transporting from reservoir to wellhead and further to processing facilities.

One can find some of the most aggressive and corrosive environments for coatings in the process work and equipment functions for Oil and Gas Upstream facilities. These conditions have typically been handled using traditional coating options such as vinyl esters, epoxies, or baked phenolic linings. While these products are often tailored to environments with elevated temperatures and pressures found within upstream and “downhole” oil and gas production, the inception of new drilling techniques and the discovery of new shale basins has morphed the landscape of corrosive environments in this market.
