Proof of Performance for ExxonMobil Refinery

This technical report details the performance of lubricants and services provided to the ExxonMobil Billings Refinery, focusing on a specific incident involving rising bearing and oil temperatures in an Ingersoll Rand air blower. The refinery faced a potential shutdown due to these escalating temperatures, which had reached 227ºF. The Mobil Serv Engineering team was engaged to troubleshoot the issue, identifying that the oil was contaminated with 50% water. They recommended immediate actions, including a bleed and feed with Mobil DTE 832 gas turbine oil and the use of a Solvancer-based oil soluble cleaner to address varnish deposits. These interventions stabilized the bearing temperatures and helped avoid a costly shutdown, resulting in reported savings of approximately $8.3 million. The report outlines the situation, recommendations made by the engineering team, and the impact of these actions on the refinery's productivity.
