Erosion‐corrosion (E−C) is one of the most intense forms of metal degradation observed whenever a static metallic material is in contact with dynamic liquid. Efficiency of industrial plant mainly depends upon the condition of various components of the equipment. Collective mechanism of corrosion and erosion results in severe surface deterioration with heavy material loss due to synergistic effect. Erosion‐corrosion is mainly observed in the pipelines used in oil and gas industries, petroleum industries, heat exchanges and mainly in marine equipment. Free flowing saline water, containing different grades of sand particles adversely affect marine equipment. Numerous reports are available discussing the impact of erosion‐corrosion in chemical industries. Single report documenting all types of prototypes, comparative study of erosion corrosion of various engineering materials and control techniques is highly limited. This review gives vivid account of various types of prototypes, comparative study of erosion‐corrosion of various engineering materials, various factors affecting tribology of system and control techniques is a systematic way. Application of corrosion inhibitors appears to be an effective method to reduce erosion‐corrosion. This review highlights the importance of understanding the mechanism of erosion‐corrosion in industrial equipment and provides a succinct overview of erosion‐corrosion synergism.

“…Ultra-deep removal of sulfur from gasoline has been a challenging issue and plays a vital economic role in the worldwide petroleum refining industry. 1,2 Significant amounts of sulfur-containing organic compounds, such as mercaptans, dibenzothiophene (DBT), and its derivatives (Th, BT), are undesirable due to their foul odors and impressive corrosive properties. 3 Hereupon, numerous corrective methods for fuel desulfurization have been introduced and adopted in recent years for clean energy generation and environmental protection.…”

To obtain clean gasoline, a new nanohybrid catalyst (TPA@PAN@CH) was synthesized by immobilizing tungstophosphoric acid (TPA) on the surface of polyaniline (PAN) and chitosan (CH) polymers. The features of the materials were detected by FT-IR, UV/vis, XRD, FE-SEM, and EDX methods. The XRD patterns demonstrate that the average crystallite size of the TPA@PAN@CH is estimated to be approximately 45 nm, which corresponds to the results of the FE-SEM.The catalytic performance of the TPA@PAN@CH was tested in the nanocatalytic oxidative desulfurization (Ncat-ODS) of gasoline and model fuels by H 2 O 2 /AcOH (volume proportion of 2:1) oxidizing agent. The best desulfurization outcomes were achieved by 0.1 g of the TPA@PAN@CH as a nanocatalyst at 35 C under mild reaction conditions. Based upon the above findings, the sulfur content could be declined from 0.4986 to 0.0193 wt%, which corresponds to performance of 96%. Mercaptan concentration decreased from 98 to 4 ppm, and the removal efficiency of model fuels declined in the order of DBT ≥ BT > Th.The high catalytic activity of TPA@PAN@CH was maintained for five cycles without significantly diminishing its performance. This work suggested the potential application of the TPA@PAN@CH for eliminating of hazardous sulfur compounds that significantly affect the efficacy of the Ncat-ODS.

“…In stress corrosion cracking, cracking occurs due to a combination of applied or residual stresses and corrosion in a variety of susceptible materials. SCC has the potential to cause catastrophic failure in a large variation of engineering components and applications, including petrochemical pipelines and mechanical components operating in submerged environments [1,2]. External SCC requires three criteria to develop on subterranean pipelines: (1) a significant magnitude of applied stress, (2) a susceptible material, (3) and a corrosive environment near the metal surface [3].…”

Stress Corrosion Cracking (SCC) process through which cracks occur in a variety of susceptible materials is a result of a combination of residual or applied stresses and corrosion. In oil and gas field, buried pipeline steels are made of low-alloy steels with a ferritic-pearlitic structure, such as X70. In dilute solutions, these materials are prone to SCC failure. The Near-neutral simulated soil solution (NS4) solution is established to imitate SCC conditions and subsequently became the industry requirement for crack growth experiments in the majority of laboratories. The strainassisted active crack pathways are considered while modelling SCC growth as an oxide film rupture and anodic dissolution process. It's been hypothesized that increasing the strain concentration can help with dissolution at the filmfree crack tip. This research focuses on estimating the SCC crack growth rate under various environmental conditions in oil and gas pipelines using finite element modelling. The simulation is carried out using the J-integral theory in the COMSOL Multiphysics program. Simulations are performed to model the crack growth rate (CGR) using slip anodic dissolution (film rupture) mechanism. The plastic strain gradient is required to compute the SCC CGR (da/dt). Because the plastic strain located at crack tip increases proportionally to the crack length as it propagates, the CGR increases as the stress intensity factor (SIF) increases. The crack growth rates increase when constant loads are applied and as the temperature rises, and elevating the cathodic potential has a minimal influence on the propagation rate of cracks but raises the material yield strength and imparts brittle behavior to it.
