Patent number: 7837855Abstract: A high solvency dispersive power (HSDP) crude oil is added to a blend of incompatible and/or near-incompatible oils to proactively address the potential for fouling heat exchange equipment. The HSDP component dissolves asphaltene precipitates and maintains suspension of inorganic particulates before coking affects heat exchange surfaces. HSDP co-blending for fouling mitigation and on-line cleaning can be affected using different concentrations of top-performing and moderate-performing HSDP crude oils.Type: GrantFiled: August 15, 2008Date of Patent: November 23, 2010Assignee: ExxonMobil Research & Engineering CompanyInventors: Glen B. Brons, Chris A. Wright -
