Take Charge of Your Crude Oil Quality

Why monitor the quality of crude oil inline?

When transporting crude oil, whether by pipeline, ground, or sea, quality testing provides critical information for decision making. Extracting samples that are sent to a lab for testing takes time. Lab test results are never in real time and sampling doesn’t represent the variation in the product between sampling times.  Only with online analysis can you get real-time continuous information to truly control your product.

Maybe your country mandates the observation of certain properties for safe transportation or to reduce pollution. Or maybe your organization needs to insure that a stable and reliable product reaches the end of a pipeline for efficient distillation. These and other goals require analysis of a variety of properties of the crude oil.  Results need to be in real time to insure continuous control and adherence to requirements. The LT Industries ParaFuel Analyzer provides just such an analysis tool.

Or maybe you are refining crude oil and need to monitor properties to optimize your distillation and cost. Blending low cost crudes into higher cost feedstocks helps reduce raw material costs. Optimization of the blend can result in significant savings. Performing that optimization in real-time with inline analysis will allow you the control needed to achieve the greatest savings.

How can the ParaFuel help you monitor your crude oil?

Whether in the pipeline, in the refinery, or anywhere along the chain of custody, there will be quality parameters that will help you better manage your product or process. The key is monitoring the parameters that mean the most to your organization. The following examples show only a few of the applications where the ParaFuel Analyzer provided the specific quality parameters to achieve required crude quality goals.

Pipeline to the refinery

The crude oil being transported in the pipeline eventually terminates at the refinery. The customer has historically had to deal with a wide variation in the quality and performance parameters of the crude. This variation complicates efficient management of the refining process and less than optimal operation. By measuring the crude oil at the injection sites, the quality of the crude in the pipeline is not only known in advance, but can be controlled through managing the injection feeds. Through online monitoring of API Gravity, Density, Sulfur, TAN, and Water the product variation in the pipeline is held stable. This allows for the incoming crude feed and resulting distillation to be managed much more effectively.


Pipeline to Distributors

Product quality can often be critical to determine type/grade/speciation, price, and safety for transport. Instantaneous online measurements of crude oil for a full range of properties allows for a deep understanding of the exact product that is being transported at any given moment.


  • Density
  • Sulfur
  • MCR
  • TAN
  • C3 – C20
  • IBP
  • 5% to 90%
  • EBP
  • Water
  • Pour Point
  • RVP
  • Flash Point

In addition to monitoring physical and quality properties of the crude oil, the ParaFuel analyzer will build a library of crude types for instant feedstock identification, without the need for extensive comparison of properties.

Understanding the crude oil in terms of ALL its defining characteristics allows pipeline managers, end users, and stake holders throughout the distribution chain to better know what is being bought, sold, or loaded into a vessel. Enhance the management of your crude oil with real-time physical and quality information.

Pipeline Flow Management

Some pipelines require injection of additives to improve transport.  Methanol injection is used to facilitate good flow properties and control freezing. The amount of methanol needs to be controlled closely. Real-time monitoring of methanol in crude oil at the injection points helps to insure good product flow characteristics. And confirming that product is within limits at the receiving end insures the product is suitable for refining or transportation and if it requires any further processing. 

Other customers monitor the physical characteristics of Asphaltene Precipitation in order to reduce precipitation in the pipeline. Others to blend higher cost and lower cost crudes at optimum blend ratios to reduce the cost of their feedstock. Together Asphaltene precipitation and methanol concentration are two ways customers manage their pipeline flow characteristics to achieve high

Inline integration for any point in the process.

The Grabner/LT Industries ParaFuel Analyzers are suitable for applications in almost any process. With probes suitable for high temperatures and pressures measurements can be done in pipes, blenders, or wherever needed. Analyzers can be mounted in the field and in hazardous areas allowing for a wide range of integration/installation options.  A benefit of the technology is that it typically can be done on the product as is, but when needed sampling systems are also available. With a solution for every need, the ParaFuel can easily be integrated into your process.
