Decanters are widely used in the biotech industry to carry out solid-liquid separations. Achieving adequate separation in the decanters reduces the amount of energy, and therefore money, required to treat the reject water in the waterline, however this is at the cost of adding chemicals to the decanters. At the current point in time, it is deemed unfeasible to control the settings of the decanters based on a cost-benefit analysis due to the complexity of accounting for savings in the waterline, so the problem is reduced to achieving decent separation with the necessary operational conditions as determined by the operators. Running decanters with a highly variable feed composition in a satisfactory manner is a task for operators who manually carry out flocculation tests to estimate the proper chemical dosage at a given point in time. This procedure is labour intensive and cumbersome. It also has a strong time component i.e delay between the result of the flocculation essay and the need of deciding for a dosage strategy. In order to circumvent this limitation, we developed a mathematical model based on on-line sensor data to estimate dosing of polymer based on upstream process information. 

Here’s how decanter centrifuges are utilized in this industry:

  1. Drilling Mud Treatment: During the drilling process, a drilling mud or drilling fluid is used to lubricate the drill bit, cool the drilling equipment, carry rock cuttings to the surface, and maintain pressure in the wellbore. Decanter centrifuges are employed to separate solids (drill cuttings) from the drilling mud, allowing for the reuse of the mud in the drilling process, reducing waste, and maintaining drilling efficiency.
  2. Oil and Gas Well Cleanup: After drilling, oil and gas wells often produce a mixture of oil, gas, water, and solids. Decanter centrifuges are used to separate these components, particularly to remove solids and water from the crude oil or natural gas. This separation process improves the quality of the oil or gas, making it suitable for further processing or transportation.
  3. Produced Water Treatment: During the production of oil and gas, large volumes of water are co-produced along with hydrocarbons. This water, known as produced water, contains contaminants such as oil, grease, and solids. Decanter centrifuges are utilized to separate these contaminants from the produced water, allowing for the water to be either reused in operations (e.g., for injection into wells for pressure maintenance) or safely discharged into the environment.
  4. Refinery Operations: In downstream processes, such as refining crude oil into various petroleum products, decanter centrifuges are used for various applications. These include the separation of water and solids from crude oil before it enters refining processes, the recovery of catalysts used in refining processes, and the treatment of wastewater generated during refining operations.
  5. Environmental Remediation: Decanter centrifuges are also employed in environmental remediation efforts in the oil and gas industry. For example, they can be used to treat contaminated soil or water by separating pollutants from the environmental matrices.

Overall, decanter centrifuges play a vital role in the oil and gas industry by facilitating the separation of different components, improving efficiency, reducing waste, and ensuring compliance with environmental regulations.
