The picture above show the example of daily log book sheet that need to be filled by operator

Daily activities (cont)Distributed Control System (DCS) data monitoringAll the plant and machineries are being monitored through DCS in the panel room to ensure that the condition maintained in safe range.From DCS panel, any abnormalities or defect can be detected and immediate action can be taken.

Project (cont..)

OGT has been operating for many years ago since 1983. For the past few years, OGT has been experienced fluctuation in produced water flow and volume during the production due to aging reservoirTimeline of the project are as follows ;162.

After a certain time where the RO membrane becomes fouled and clogged with dirt and mineral deposited on the membraneReduced the RO performanceCheck the conductivity of MRO and BROHow to clean

During the cleaning process, a flexible hose will attached from RO Cleaning Skid to Inlet of RO Filter Membrane while another flexible hose is attached at the RO reject water outlet to drain out Chemical used ie : Acid HydrochloridFormalin (caustic)Detergent

External Factor (Total running hours) = taken from the daily log sheet templateStandby Hours= 24- (total running hours+ total not available)Internal Factor = data taken from the daily log sheet templateTotal daily Prod = data taken from the daily log sheet templateTotal slowdown = (design capacity* running hours) total daily prod ie. (110*11.38 )- 1410 The template of OEE used in UK)

Conclusion PETRONAS GAS BERHAD as host company has given me a very good technical exposure and experience opportunity.Based on the on the exprience and exposure during my training period in UK, I standly believe that the objective of the training has been achieved.To familiarize and expose the student with the real working environment To widen skill in safety practices, work ethics, communication, management, etc

Treatment of Industrial waste water and produced water using membraneFinal Year Project 123Name : Izzah Sofiahanun Binti IshakProgramme : Bachelor of Engineering (Hons) Oil and GasUniversiti : Universiti Teknologi MARA (UiTM)

outlineIntroductionProblem statementObjectiveScope of workSelected literatureMethodologyExpected result

24

introductionIndustry oil and gas have become significance for developing country such as Malaysia. However, the increasing industrialization has given some impact on ecosystem and environment which human relies on.Discharging industrial waste water without being treated further can contaminate water and soil that may lead disturbances to the ecosystem. Once the organic pollutants are discharged into watercourse, biodegradation by the microorganism will take place.

25

. During the biodegradation process, the microbes will consume the dissolved oxygen in the water. This can reduce the oxygen supply in water needed by the aquatic life and can kill the aquatic life.

25

Problem statementWaste water from the refinery and industry has become one of major sources to water pollution. This is because in the various type of industries, a large amount of fresh water is used to be raw material, as a mean of production and also for cooling purpose.Concerning on the environment and ecosystem, the discharge of waste water need to be treated and improve its quality before being released to river, coastal or lake.The use of membrane filtration processes ie microfiltration, nanofiltration, ultra filtration and reverse osmosis has offer a lot of advantages for the treatment.26

objectiveThere are two main objectives for this research which are as follows:To characterize the parameter of industrial waste water after treatedTo treat the industrial waste water using different characteristic of membrane.

27

Scope of workThe scope of this research project comprised of two approaches i.e. :Material preparationMaterials used in this research are flat membrane (polymersulfone and polyethersulfone) and industrial waste water (sample from UK)2. Characterization of sample waste water by using 7 parameter i.e : pH, BOD, COD, PO4, NH3, TSS, FCL28

Selected literature

This paper focus on treatment of oily wastewater coming out from the post-treatment unit of petroleum industries.Use polysufone with additives ie : polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG)The experimental results showed oil retentions of almost all the membranes were over 90% oil concentration in the permeate was below 10 mg/L29Ghoshal, A., & Purkait, M. (n.d.). Ultrafiltration of stable oil-in-water emulsion by polysulfone membrane. Journal of Membrane Science, 325(2008), 427-437. Retrieved from Science Direct.

where finely divided oil droplets are uniformly dispersed in large volumes of water

29

methodologySynthesis of membrane Raw material : polymer sulfone and polyether sulfone bead Additive: polyvinylpyrrolidone (PVP)Solvent : N-methyl-2-pyrrolidone (NMP) Measured amount of polymer (PSf) and (PES) along with PVP was dissolved in the solvent (NMP) at room temperature (25 C) and relative humidity (72%) to make the casting solution.
