Increase Profits and Flexibility with Product Pipeline Interface Detection

Dec 14 2017 Read 681 Times

Petroleum product pipelines are an efficient method of delivering product to distribution terminals. These pipelines are multi-purpose, in that they deliver many different products through one or two pipes. Usually fuel products are injected into the pipe sequentially, with no barrier between products.

What Happens When Transitioning?

When transitioning from one fuel to another (i.e. diesel to gasoline, high to low octane) a mixture phase is present, where two products are blended over a period of time. Terminal operators must switch between Product A, Slop, and Product B tankage precisely, otherwise product quality can suffer, and/or too much product must be re-processed. Mistakes can be costly and time consuming.

Today, NIR spectroscopy (either full spectrum DG-NIR or discrete wavelength photometers) can be used to detect both quantitative and qualitative pipeline interface transitions. This is achieved by comparing the current sample in the pipe with a library of materials in the analyser’s database. The data provides significant information about the product and classifies it as one of various grades of gasoline, diesel, fuel oil, etc. to allow automatic valve switching, so that more fuel can be used and sold, without waste.

Guided Wave’s Technology Allows the Refinery to:

  • be proactive and transition fuels in real-time with optimisation
  • complete target changes seamlessly while minimising quality risks
  • increase gasoline production volumes
  • manage fuel delivery to maximum profit or maximum volume, depending on the particular refinery constraints at that time

The Smart Choice for Pipeline Interface Detection

Guided Wave’s DG-NIR process analyser systems are fully implemented for real-time fuel measurement and control to optimise online pipeline transitions. The benefits of real-time optimisation are many:

  • minimise the amount of product discarded (slop)
  • faster response to dynamic changes in the pipeline operations
  • greater flexibility to transport multiple grades of gasoline at the lowest cost
  • increase opportunity to optimise the pipeline delivery and storage for greater profitability

See how Guided Wave’s DG-NIR technology can be used in your pipeline to quickly and efficiently identify the changing samples giving you uncompromised quality, competitiveness and increased profitability.
