“…Corrosion professionals, asset owners and coating formulators are still focused on understanding and lowering the cost of corrosion and mitigating its effect on the life of structure [2]. Based on to atmospheric exposure conditions corrosion is classified as wet corrosion and dry corrosion [3] and based on mechanism of corrosion, it can be classified in different types; some of them are, uniform corrosion, stress corrosion, galvanic corrosion, crevice corrosion, pitting corrosion, inter-granular corrosion, erosion corrosion and water line corrosion [4] [5].…”

Protection of metal is primary undertaking for any design engineer and coating formulator. Construction of large scale equipment and structure involves huge investment in terms of money, time, manpower and other resources. In economic aspects, the life of such structure must as long as possible to get the best return on its investment. To improve the life of such huge structures, it is becomes mandatory to protect the metal substrates from corrosion. Application of corrosion resistant coating is one of the most intriguing, robust, practical and efficient techniques to safeguard the metal from corrosion. Graphene is novel material and got prodigious application due to its extraordinary features. Lot of research has been conducted since last decade for modifying the graphene and making the best use to formulate corrosion resistant coating. The use of graphene in the coating creates an obstacle and increases the convoluted path for corrosive medium to reach the metal. As the path to reach to metal is increased, it delays the corrosion medium to reach up to the metal and thus corrosion of metal can be avoided. In this literature review is conducted for various aspects of corrosion, importance of graphene in coating formulation is discussed, which includes chemical modifications of graphene, effect of graphene concentration on corrosion inhibition and contact angle of coating. This review also discussed about the importance of water based corrosion resistant coating to avoid the environmental damages. Keywords: Graphene, Corrosion resistance, contact angle, water base coating, metal protection, corrosive media, corrosion inhibition.

“…Application of corrosion inhibitor for the prevention of corrosion found prominent attention. The suitable concentration of corrosion inhibitor reduced the corrosion rate without altering the concentration of corrosive media [1]. For the control of metal corrosion, various kinds of inhibitors including inorganic compounds, plant extract, and organic molecules are commenced for the mitigation of metal corrosion as illustrated in Figure 1 [2].…”

Metal corrosion constitutes degradation of metals in the presence of favorable corrosive atmosphere. It worsens metal quality. The prevention of metal corrosion is so significant to save metals for their better utility. Corrosion inhibitors are widely used for the mitigation of metal corrosion. Small organic molecules as corrosion inhibitors are showed prominent corrosion inhibitive property because of their unique electron donating capacity to the metal orbitals. The bonding occurred between organic molecules and metals are main aspect to retard the corrosive environment toward metal.

“…To overcome these issues, the most cost-effective and widely adopted engineering solution for controlling scale deposition and corrosion is the application of chemical inhibitors, including scale inhibitors and corrosion inhibitors [18][19][20]. Scale inhibitors are chemical substances, such as the phosphonates, polyacrylates, and poly-maleates, added in a low dose (typically in the level of a few mg L −1 ) to the brine to delay or retard the formation of scale [21][22][23]. Some polymeric scale inhibitors, such as polyaspartate and polyepoxysuccinic salts, can also have corrosion inhibition properties in addition to their more common use as a scale inhibitor [24].…”

Production chemistry is an important field in the petroleum industry to study the physicochemical changes in the production system and associated impact on production fluid flow from reservoir to topsides facilities. Mineral scale deposition and metal corrosion are among the top three water-related production chemistry threats in the petroleum industry, particularly for offshore deepwater and shale operations. Mineral scale deposition is mainly driven by local supersaturation due to operational condition change and/or mixing of incompatible waters. Corrosion, in contrast, is an electrochemical oxidation–reduction process with local cathodic and anodic reactions taking place on metal surfaces. Both mineral scaling and metal corrosion can lead to severe operational risk and financial loss. The most common engineering solution for oilfield scale and corrosion control is to deploy chemical inhibitors, including scale inhibitors and corrosion inhibitors. In the past few decades, various chemical inhibitors have been prepared and applied for scaling and corrosion control. Phosphorus-based polymers are an important class of chemical inhibitors commonly adopted in oilfield operations. Due to the versatile molecular structures of these chemicals, phosphorus-based polymeric inhibitors have the advantage of a higher calcium tolerance, a higher thermal stability, and a wider pH tolerance range compared with other types of inhibitors. However, there are limited review articles to cover these polymeric chemicals for oilfield scale and corrosion control. To address this gap, this review article systematically reviews the synthesis, laboratory testing, and field applications of various phosphorus-based polymeric inhibitors in the oil and gas industry. Future research directions in terms of optimizing inhibitor design are also discussed. The objective is to keep the readers abreast of the latest development in the synthesis and application of these materials and to bridge chemistry knowledge with oilfield scale and corrosion control practice.
