Alkylation units ensure facilities meet gasoline quality specifications and allow for the production of premium gasoline grades, adding significant economic value to the refinery operation. These units are extremely susceptible to aggressive corrosion. Corrosion can lead to an HF release, which may cause significant production loss and place the health and safety of the refinery staff and local community at risk.Measuring corrosion damage in HF acid alkylation units using traditional methods is difficult. Iron fluoride can scale and build up on the inside of pipes, confusing normal ultrasonic thickness measurements. Additionally, traditional intrusive probes, or frequent manual inspections present safety risks due to the hazardous environment of these units.
Emerson’s new version of DataManager solves these problems by helping refiners gain a better understanding of the correlation between corrosion rates and upsets, or changes in process conditions.Engineered with a unique new signal processing module, the solution delivers data directly to the engineer’s desk with wireless, non-intrusive sensors that communicate with an Emerson Wireless Gateway, reducing the frequency of manual inspections. These sensors are designed to withstand harsh, potentially high-temperature refinery conditions.
"Today's refineries require monitoring technology that can safeguard their people and their business," said Jake Davies, global corrosion product director at Emerson's automation solutions business."Reducing the risks from HF acid attacks and minimising the potential for leaks allows facilities to better forecast equipment lifespan while also securing the health and safety of their employees."
