A Review on: Biocidal Activity of Some Chemical Structures and Their Role in Mitigation of Microbial Corrosion

Abstract

Microbial corrosion has developed a foremost problematic in the oil and gas industrial field. This problem is by reason of the continual usage of water swamping in promoting oil recovery. This water moistens the walls of oil pipelines. Microbial corrosion is also present in other industries such as nuclear power reactors and in most hydropower applications. Increased corporate infrastructure also leads to increased microbial corrosion. Sulfate Reducing Bacteria (SRB) is considered as the main kind of bacterial which cause of pipeline corrosion. Because of microbial deterioration is not understood, until recently, there is no clear mechanism to explain why and how microbial corrosion occurs because of the complexity of this area. The new theory of biocatalytic cathodic sulfate reduction is bio-electrochemistry based. In this theory, the bioenergetics can explain why microbial corrosion occurs, while the extracellular electron transference theory is capable of explain how microbial corrosion happens. The microbial corrosion can be caused by nitrate reducing bacteria, which led to an analogous biocatalytic cathodic nitrate reduction theory. The electron mediator assessment intended to validate the extracellular electron transference progression which anticipated in biocatalytic cathodic sulphate reduction. The electron mediators like riboflavin and flavin adenine dinucleotide were accomplished of hastening the microbial corrosion by indorsing electron transport flanked by an iron surface and a biofilm. In case of deficient in organic carbon, the elemental iron substituted the organic carbons as an energy source/electron donor for SRB to get their conservation energy. Under unembellished undernourishment of organic carbon, the largest pit depth was accomplished, which was consistent with the estimate of biocatalytic cathodic sulphate reduction. The developing request and crucial necessity in oil and gas industry is to find an effectual method to avoid and/or mitigate microbial corrosion at a rational cost.

Biokorosi Dan Teknologi Pencegahannya Di Industri Minyak Dan Gas

“…Mikroorganisme membutuhkan empat elemen untuk berkembang yaitu sumber karbon, air, donor elektron dan akseptor elektron [20]. Hidrokarbon dan senyawa organik lainnya merupakan sumber makanan yang sangat baik untuk berbagai macam mikroba terutama jenis bakteri, Archaea dan Eucarya [25]. Dari tiga mikroorganisme yang ada di industri minyak dan gas, bakteri mendapat perhatian paling besar dalam studi MIC [25].…”

“…Hidrokarbon dan senyawa organik lainnya merupakan sumber makanan yang sangat baik untuk berbagai macam mikroba terutama jenis bakteri, Archaea dan Eucarya [25]. Dari tiga mikroorganisme yang ada di industri minyak dan gas, bakteri mendapat perhatian paling besar dalam studi MIC [25]. Studi terbaru menunjukkan bahwa bakteri pereduksi sulfat atau SRB (sulfate reducing bacteria) adalah kontributor utama MIC dengan menghasilkan hidrogen sulfida (H 2S) [26].…”

“…Selain itu, SRB juga memiliki kemampuan metabolisme lainnya antara lain dapat mereduksi nitrat dan tiosulfat serta pengambilan elektron langsung dari permukaan logam [33]. SRB dapat memperoleh karbon dan energi dari asam organik dan nutrisi, seperti laktat, asetat dan piruvat [25]. SRB sering dianggap sebagai kontributor utama biokorosi karena kapasitas metabolismenya untuk menghasilkan H2S [32].…”

Cost-Effective and Green Additives of Pozzolanic Material Derived from The Waste of Alum Sludge for Successful Replacement of Portland Cement

“…Other methods include employing thick forms of concretes that have a low water/cement (w/c) ratio and/or by adding additives such as micro silica that may diminish porosity, which in turn slows the chloride transit rate. Both methods are examples of alternative ways since these approaches are instances of different approaches that might be used 41 .…”

A Review on The Chemical Compositions of Natural Products and Their Role in Setting Current Trends and Future Goals

“…Corrosion inhibitors are the most practical way to deal with this problem. Plant extracts have been extensively reported in the literature as an alternative to conventional corrosion inhibitors [116][117][118]. This is because extracts from plants have been shown to inhibit metal corrosion significantly.…”
