APPLICATION EXAMPLES
GPP Onshore Argentina – Installed in 2019
Enhancing Oil Recovery with Polymers
The end user uses polymers to increase the efficiency of oil recovery. Polymers require a large amount of water to hydrate the polymer before it is injected into the tank, and this is where production water is used for hydration. One of the main quality controls for production water is that the oil content should be <40 ppm (parts per million). A general purpose probe (GPP) is used at each site to monitor the oil content of the production water prior to mixing with the polymer and is set to alarm if the concentration exceeds 40 ppm.
GPP Onshore Qatar – Haffar Petroleum – Installed in 2020
Detection of hydrocarbons in seawater for a power installation
Seawater is used as a source of water for a power installation, so it is crucial that the seawater does not contain hydrocarbons. The GPP is mounted horizontally on the tank wall with a 90° radius, so that the probe reaches approximately 1 meter below the water surface. The water level is maintained so that the probe is constantly submerged and therefore provides reliable oil concentration levels. When the concentration level exceeds a critical value, water intake is stopped to allow the oil to settle for removal. The customer indicated that a low-maintenance solution was necessary because the tank is unmanned. Furthermore, a bypass solution was not feasible, so GPP was selected as the best available solution.
