“…Firstly, operating conditions for an OiWM filtration system was optimized by deploying the full factorial design methodology, where the different operating conditions was analyzed with respect to permeate flux, fouling resistance, and TOC rejection [92]. Secondly, optimal operating conditions for MF and UF systems treating an OiWM where found in [93]. The Taguchi method was deployed to find the optimal conditions among temperature, TMP, CFV, and back pulse time.…”

The offshore oil and gas industry is experiencing increasing water cuts as the reservoirs mature. The increase in produced water stresses the currently deployed deoiling technologies, resulting in more oil in the discharged water. Deploying membrane filtration to reduce the hydrocarbon concentration inherits additional complications related to fouling of the membranes: A process where the accumulation of material within and on the membrane surface adds additional flow resistance. This paper reviews and analyses the fouling detection, removal, prevention, dynamical and static modeling, with emphasis on how the membrane process can be manipulated from a process control perspective. The majority of the models rely on static descriptions or are limited to a narrow range of operating conditions which limits the usability of the models. This paper concludes that although the membrane filtration has been successfully applied and matured in many other industrial areas, challenges regarding cost-effective mitigation of fouling in the offshore deoiling applications, still exist. Fouling-based modeling combined with online parameter identification could potentially expand the operating range of the models and facilitate advanced control design to address transient performance and scheduling of fouling removal methods, resulting in cost-effective operation of membrane filtration systems. With the benefits of membrane filtration, it is predicted that membrane technology will be incorporated in produced water treatment, if the zero-discharge policies are enforced globally.

“…The rapid flux decline demands both physical cleaning, i.e. backflushing or backpulsing, and chemical cleaning in place (CIP) to sustain the flux, with physical cleaning efficacy demonstrated in a number of studies (Li and Lee, 2009;Ebrahimi et al, 2010Ebrahimi et al, , 2012Silalahi and Leiknes, 2011;Reyhani et al, 2015;Weschenfelder et al, 2015ab). As a consequence of the large number of variables impacting on operation, reported permeability values for CMs challenged with PW or its analogues have been very wide-ranging, from below 20 to ~800 LMH/bar (Table 1).…”

“…On the other hand, evidence from demonstration trials (Lee et al, 2005;Pedenaud et al 2011) and recent extended trials (Weschenfelder et al, 2015b) indicate very significant permeability loss over a period of several days. There have also been few studies comparing candidate CM materials; comparative studies have tended to focus on the relative performance of ceramic and polymeric membranes (Vitai et al, 2009;Reyhani and Meighani, 2015). Studies which include CM chemical cleaning efficacy (Ebrahimi et al, 2010;Weschenfelder et al, 2015b) have not encompassed long-term use of the cleaned membrane.…”

Produced water (PW) generated from oil exploration requires rigorous removal of suspended matter (free oil and particulate solids) as tertiary treatment (downstream of hydrocyclone and gas flotation) if it is to be re-injected into low-permeability reservoirs. The viability of membrane filtration for this duty is largely dependent on sustaining a high membrane flux to minimise the process footprint. A pilot-scale study of PW filtration using crossflow multi-channel ceramic membrane technology has been conducted to identify the appropriate membrane characteristics for sustaining the flux whilst maintaining the required treated water quality. Membranes based on two materials (silicon carbide, SiC, and titanium dioxide, TiO2) and two different pore sizes were challenged with real PW samples taken from oil platforms operating on the Arabian Gulf. The membranes were characterised according to the overall permeability decline rate and the end permeability. Results suggest that SiC membranes outperform TiO2 ones with respect to sustainable permeability under the same operating and maintenance conditions. The SiC microfiltration membrane provided anomalously high permeabilities but also the highest fouling propensity. Results suggest that whilst the high fluxes (1300-1800 L m-2 h-1) are attainable for the technology, this is contingent upon the application of an effective chemical clean.

“…For some wastes the membranes have been found to be prone to fouling by waxes and asphaltenes [17]. Further good oil removal results have been obtained using an alumina membrane, with 95%-99% removals of oil [47,48]. A commercial tubular α-Al2O3 MF membrane with a pore size of 0.2 µm has been used to remove 95% of the oil from a refinery effluent, operated at 32.5 • C, leaving but 4 mg/L in the permeate [49].…”

The current situation with the problems associated with the removal of oil from wastewaters by membranes is being explored. Many types of membranes have been investigated-organic polymers, inorganic or ceramic species and hybrids of the two. Polymeric membranes can be designed to facilitate the passage of oil, but the more successful approach is with hydrophilic types that encourage the passage of water. Ceramic membranes have an advantage here as they are less often irreversibly fouled and give a higher recovery of oil, with a lower flux decline. Furthermore, they can be cleaned up by a simple heating procedure. More attention should be given to understanding the mechanism of fouling so that operating conditions can be optimised to further reduce fouling and further decrease the flux decline, as well as assisting in the design of antifouling membranes. Another obstacle to ceramic membrane use is the high cost of manufacture. Cheaper starting materials such as clays have been surveyed.
