Corrosão em dutos de petróleo e gás: revisão e estudo de caso na cidade de Macau

Abstract

The demand for oil continues to be very high, taking into account that world production is estimated at around 89.8 million barrels produced daily, used for many purposes, including the main one - energy -, it currently moves the global economy, generates profits and capital increase for countries with this natural resource. Brazil is concentrated in its production in the states of Rio de Janeiro and Rio Grande do Norte. The city of Macau located in Rio Grande do Norte has approximately 78 oil wells in operation at the moment, currently with greater exploration in mature wells previously used for extraction. Despite the economic prosperity provided by oil and natural gas production, corrosion has been an obvious obstacle to obtaining greater profits from the transport, storage and production of petroleum derivatives, as it compromises structures and can lead to leaks with capital and environmental damage, in addition to natural disasters. The objectives of this work are aimed at better understanding the relationship between corrosion and damage caused to oil and gas pipelines, as well as to prove the topics presented in the theoretical framework, based on the methodology of an online form aimed at a professional working in the industry, who verified the veracity of the facts reported by the scientific research in this article – commonly the incidence of corrosion induced by acid gas attacks and BRS bacteria, presence of hydrogen sulfide, carbon dioxide and oxygen gas, a difference evident in the constitution of ducts depending on the environment in which they are inserted, and mapping with corrosion coupons mentioned prior to the application of the digital form – concluding the success in directing the bibliographic review.
