Spectroscopic Online Process Monitoring for More Efficiency and Yield in Oil Production

Before being used, crude oil and natural gas are being processed in refineries into mineral oil products such as petrol, diesel heating oil, etc. or pretreated as chemical raw materials. Most of the oil and gas extracted goes to the heating and energy market, only one third is being used in form of chemical raw materials. Petroleum and natural gas products are processed into numerous household and industrial products, e.g. cosmetics, household cleaners, vehicle components and much more.

The Challenge

Oil Production – Complex, Dangerous and Expensive

The exploitation of oil deposits is technically very complex and production costs are high. The major challenges of the petro chemistry therefore include, besides the development of new oil deposits, the increase of yield from oil fields that have already been exploited. For the optimal control of the production process and the best possible yield of high-quality oil, continuous monitoring of the water and gas content is indispensable. Excessive production can lead to dilution and a decrease in yield. To avoid this, it is important to collect and evaluate drill samples at regular intervals. Checking the water content during the production helps to optimize the pump performance so that in the end more oil can be produced in the same time.

The Application

Manual Sample Taking – Inaccurate, Cumbersome and Time-Consuming

The precise measurement of the water content in oil is not an easy task. Fluctuations of the solids, the gas volume fraction or variations in salinity can entail inaccurate measurement results. Besides, oil is very viscous and the environmental conditions vary strongly. Conventional measurement methods based on phase separation are often not precise enough and the analysis of the measurement data in the laboratory cumbersome and time-consuming. Due to the risk of explosion at the oil pipeline, products used in this environment must be certified according to the ATEX product directive 2014/34 / EUATEX.

The Solution

Spectroscopic Measurements in Real- Time directly at the Pipeline – Precise Measurement Results, Higher Output

A more precise measurement of the water content in oil directly at the pipeline and in real time can be achieved applying spectroscopic measurement methods. This measurement technique makes use of big difference in the absorption of near infrared light (NIR) between crude oil and water. The absorption spectrum is based on water and not on the dissolved salts. With the help of WLR (water in liquid ratio) sensors based on a NIR transmission measurement cell, oil and water can be measured in real time and large-scale systems based on phase separation can be avoided. The risk of impaired measurement results due to emulsions or variation in salinity are eliminated.

Precise measurements under harsh process conditions

For transmission measurements under harsh and highly fluctuating process environments, Hellma has developped particularly robust products wicht, thank to the material used for construction and the absence of elastomere seals, have a high level of pressure and temperature resistance and are completely maintenace-free. Depending on the structural conditions at the measuring location, two different designs of the product series can be uesd. Both use a robust metal sealing, a Hellma specific technology.

Excalibur HD FCP20

Choose the correct product for your measuring location

The measurement cells of the FCP series have an adjustable middle part, which results in greater flexibility of the flow cells and their application. The optics are very compact and thus particularly suitable for smaller pipe diameters. The Hellma HD FCP20 measurement cell is based on standard screw connections and is therefore compatible with standard pipe connectors. Thus, larger path lengths for gas measurements can also be implemented. A further advantage of this measurement cell is its gas filling that prevents condensation of moisture in the optics.

Excalibur HD FPT

The Hellma Excalibur HD FPT can be used if a flange for a sensor is already available. This high-performance probe also has a second barrier, making the product even more secure against leaks. Just like the FCP measurement cell, this model also has an inertization with protective gas, which means that measurements with liquid gases are also possible.
