Tests were carried out using Artemisia vulgaris. Even though ABSTRACT: It is known that corrosion is a natural process and is impossible to prevent completely. aqueous corrosion, or corrosion in environments where water is pres-ent. These are as an admixture, surface impregnation of existing concrete structures, or coated rebar cast in concrete. The deicers, NaCl, CaCl 2 , MgCl 2 , have an environmental impact as they might leach into the soil; become toxic to humans, animals, and plants; and reach water bodies. In the 1960s, the company developed new scale inhibitors, which were synthetic or polymeric products, scale inhibitors, and higher scale inhibition rate than natural scale inhibitors, which can meet the requirements of higher scale inhibition. Therefore, versatile materials are required in order to keep corrosion rates in control. Their valorization expands possible applications in industrial fields other than âwaste to energyâ in the perspective of circular economy. We summarize the research focused on using natural products that have been used as green inhibitors in various aggressive media for corrosion protection of different alloys and metals as depicted in Table 1.

As in addition to being environmentally friendly and ecologically acceptable, plant products are inexpensive, readily available and renewable. Scale can form as a reaction between gases and ions present in drilling fluids. Protecting Pipelines Using Vapor Phase Corrosion Inhibitors. Scale inhibitors work to inhibit the crystallization that forms scale. The deterioration of materials because of a reaction with hot gases, however, is included in the definition of corrosion given here. Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, carbonate or sulfide.It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment. The correlation between the molecular structure and corrosion inhibitor efficiency of the oligomers were studied. Corrosion is caused by metals attempting to return to their natural state. The environmental toxicity of organic corrosion inhibitors has prompted the search for green corrosion inhibitors as they are biodegradable, do not contain heavy metals or other toxic compounds. The examples are numerous such as henna, olive, shirsh zallouh, vanillin, natural honey, khella, onion, ficus, opuntia,many oils extracted from different parts of different plants and many others. Thus we only try to control corrosion. ... will be driven by higher oil and natural gas output, particularly from shale formations, as well as by increasing chemical production and an expanding economy. In fact, the use of inhibitors is a well-known strategy when metal corrosion needs to be prevented, controlled, or retarded.

So many inhibitors specially Green Inhibitors as well as Drugs thatâs used in Pharmaceutical fields that can be used as Corrosion Inhibitors. Despite what most people assume, motor oils have no natural ability to protect against rust or corrosion. This results primarily from the industryâs extensive use of carbon and low alloy steels, which, for many applications, are economic materials of construction that generally exhibit poor corrosion resistance. In fact, the use of inhibitors is a well-known strategy when metal corrosion needs to be prevented, controlled, or retarded. NH oil-based rustproofing with rust inhibitors will displace moisture and cut off oxygen. Inorganic CIs are those in which the active substance is an inorganic compound. Corrosion inhibitors minimize or avert corrosion when added in small concentrations to a corrosive medium (Riggs, 1973) by forming monomolecular film-adsorbed surface (Mainier et al., 2003), which obstructs the direct contact between metal and corrosive agents (Ebenso et al., 2012).They have been classified based on sources (as organic or inorganic) and techniques (as synthesized or extracted).
