INTEGROIL presents first results TUPRAS Izmit refinery pilot
The H2020 INTEGROIL project is conceived to develop and demonstrate a solution to increase water reuse in the oil and gas sector, one of the eight industrial sectors with the highest water consumption. In this way, by reducing fresh water dependence the project contributes to improve the sustainability of this industrial sector.
Within the project, demonstration in upstream and downstream scenarios were foreseen. After the upstream demonstration period that ended in August 2018, INTEGROIL plant was shipped to Turkey and commissioned successfully in TUPRAS Izmit refinery (Figure 1). From October 2018 the INTEGROIL pilot plant is continuously treating refinery wastewater and operated by the refinery own personnel.
The preliminary results obtained so far are the following:
• 95% of turbidity removal by the dissolved air flotation (DAF) process
• Up to 93% of COD removal and 90% of BOD removal by the membrane bioreactor (MBR) process.
• Up to 90% total carbon (TC) removal by the catalytic wet air oxidation (CWAO).
• 97.49% normalized salt rejection by the reverse osmosis (RO) process.
Although the results are highly encouraging, we expect to improve them in the next two months, thanks to the advantages provided by the developed Decision Support System (DSS) that assists in plant operation. In this regard, the DSS has been adapted to the downstream scenario (i.e. the MBR unitary process has been added) and has been under operation. This has enabled, on one hand, assessing the suitability of the DSS in another scenario, and on the other, obtaining data on the performance of each process when dealing with refinery wastewater. The data compiled is currently being used to forecast each unitary system performance, by means of big data and machine learning tools. This will enable further tuning the algorithm capable of selecting the optimal treatment scheme (based on the incoming water quality and the reclaimed water final use, with minimal costs), as well as facilitating the optimisation of each process by identifying those variables with greater influence.
