Oil & gas refining & petrochemicals

Measuring refractive index and liquid concentration in oil and natural-gas refining and petrochemical industries

Vaisala K-PATENTS® Process Refractometers provide accurate in-line refractive index, concentration and density measurements that help to improve oil and gas refining and petrochemical operations such as multi-product custody transfer and loading/ unloading operations, sulfuric acid alkylation, amine gas treating, gas dehydration and lube oil production. The purpose is to eliminate sampling, improve product consistency and operations safety and optimize the process. 

Serving oil, gas and petrochemical industry measurement needs

Vaisala K-PATENTS® Process Refractometers are designed to measure liquid concentration or density in diverse oil, gas, and petrochemical industry applications. The purpose is to eliminate sampling, improve product consistency and operations safety and help to optimize the process. Uniform product quality and minimum waste can be achieved by continuous monitoring. Unlike periodical sampling, continuous monitoring can provide instant feedback to changes in the process. This instant feedback can then be used to control the process in real-time.

The Refinery Process Refractometer is a heavy-duty refinery model designed to meet the unique requirements of the oil and gas refining and petrochemical industries. Typical applications include accurate liquid concentration measurements, e.g. 

  • Sulfphuric acid in alkylation 
  • Glycol or amines in gas processing, e.g. gas dehydration and amine gas treating (sweetening)
  • Multi-product (crude oil, fuel oil, diesel) interfaces in custody transfer and loading and unloading operations.
