Abstract
Because of the Covid-19 pandemic, worldwide consumption of petroleum fuels is reduced due to complete or partial lockdown in most of the countries. The abridged expenditure of liquid fuels imposes pressure on petroleum refinery industries for their processing, storage and transport. Prolonged storage of crude and purified petroleum can cause several corrosion failure problems that can adversely affect the efficiency, storage and transport efficiency of the petroleum refineries. Some of the major corrosion failures encountered because of the prolonged storage are Top-of-Line Corrosion (TLC), Bottom-of-Line Corrosion (BLC), Bottom-of- Storage Tank Corrosion (BSTC), Liquid-Air interface corrosion (LAIC): Differential Aeration Corrosion (DAC). Generally, TLC is attributed due to condensation of water-droplets on the inner-wall of the transport pipelines and closed storage tanks. BLC is accredited due contamination of solid deposits, rusts and scales on the bottom of the transport pipelines and closed storage tanks. DAC is attributed due to the formation of differential aeration cells at the interface of liquid petroleum and open air. Present prospective aims to describe the adverse effect of prolonged storage of petroleum fluids because of Covid-19 pandemic.
