  • Coupling of CFD and semiempirical methods for designing three-phase Condensate Separator: case study and experimental validation
    Journal of Petroleum Exploration and Production Technology, 2019
    Co-Authors: Ahmadreza Ghaffarkhah, Zahra Azimi Dijvejin, Mohammadjavad Ameri Shahrabi, Mostafa Keshavarz Moraveji, Masood Mostofi
    Abstract:

    This study presents an approach to determine the dimensions of three-phase Separators. First, we designed different vessel configurations based on the fluid properties of an Iranian gas Condensate field. We then used a comprehensive computational fluid dynamic (CFD) method for analyzing the three-phase separation phenomena. For simulation purposes, the combined volume of fluid–discrete particle method (DPM) approach was used. The discrete random walk (DRW) model was used to include the effect of arbitrary particle movement due to variations caused by turbulence. In addition, the comparison of experimental and simulated results was generated using different turbulence models, i.e., standard k – ε , standard k – ω , and Reynolds stress model. The results of numerical calculations in terms of fluid profiles, separation performance and DPM particle behavior were used to choose the optimum vessel configuration. No difference between the dimensions of the optimum vessel and the existing Separator was found. Also, simulation data were compared with experimental data pertaining to a similar existing Separator. A reasonable agreement between the results of numerical calculation and experimental data was observed. These results showed that the used CFD model is well capable of investigating the performance of a three-phase Separator.

  • adsorption of residual oil from palm oil mill effluent using rubber powder
    Brazilian Journal of Chemical Engineering, 2005
    Co-Authors: A L Ahmad, Norliza Ibrahim, Subhash Bhatia, Sundaram Sumathi
    Abstract:

    Abstract - A synthetic rubber powder was used to adsorb the residual oil in palm oil mill effluent (POME). POME is the wastewater produced by thepalm oil industry. It is a colloidal suspension which is95 -96% water, 0.6-0.7% oil and -5% total solids including 4 -4% suspended solids originat2 ing in the mixing of sterilizer Condensate, Separator sludge and hydrocyclone wastewater. POME contains 4,000 mg dm -3 of oil and grease, which is relatively high compared to the limitof only 50 mg dm -3 set by the Malaysian Department of Environment. A bench-scale study of the adsorption of residual oil in POME using synthetic rubber powderwas conducted using a jar test apparatus. The adsorption process was studied by varying parameters affecting the process. The parameters were adsorbent dosage, mixing speed, mixing time and pH. The optimum values of the parameters were obtained. It was found that almost 88% removal of residual oil was obtained withan adsorbent dosag e of 30 mg dm

    A synthetic rubber powder was used to adsorb the residual oil in palm oil mill effluent (POME). POME is the wastewater produced by the palm oil industry. It is a colloidal suspension which is 95-96% water, 0.6-0.7% oil and 4-5% total solids including 2-4% suspended solids originating in the mixing of sterilizer Condensate, Separator sludge and hydrocyclone wastewater. POME contains 4,000 mg dm-3 of oil and grease, which is relatively high compared to the limit of only 50 mg dm-3 set by the Malaysian Department of Environment.

The adsorption process was studied by varying parameters affecting the process. The parameters were adsorbent dosage, mixing speed, mixing time and pH. The optimum values of the parameters were obtained. It was found that almost 88% removal of residual oil was obtained with an adsorbent dosage of 30 mg dm-3 and mixing speed of 150 rpm for 3 hr at a pH 7. Adsorption equilibrium was also studied, and it was found that the adsorption process on the synthetic rubber powder fit the Freundlich isotherm model.
