Heavy oils simulation, modeling capabilities

New capabilities apply the precision of conventional oil simulation software to the unique and specialized processing and modeling requirements of heavy oils.


Invensys Process Systems demonstrated the enhanced SimSci-Esscor PRO/II 8.1.2 software solution at the World Heavy Oils Congress March 10 -12 in Edmonton. New capabilities apply the precision of conventional oil simulation software to the unique and specialized processing and modeling requirements of heavy oils.
Enhancements to PRO/II include a new petroleum characterization procedure specifically designed for heavy oils. This new procedure is used to extrapolate critical properties and molecular weights with normal boiling points well beyond 1000 degrees K. With PRO/II software, Invensys is helping heavy oils industry clients solve refining problems that result from inaccurate or incomplete simulation inherent in heavy oils processing.
"We recognize the importance of heavy oils in the worldwide market, and are developing solutions that bridge the gap between simulation software that is used to model conventional oils and the special requirements for accurately modeling heavy oils," said Joseph McMullen, PRO/II product manager. "We've taken the first of many development steps to address the growing needs for simulation of bottom-of-the-barrel refining."
Invensys Process Systems is continuing to develop and implement additional methodologies that can accurately simulate very high viscosity, low API gravity, numerous impurities such as sulphur and heavy metals and other heavy oil properties, to predict the range of heavy oil physical properties. Invensys' advanced applications business has established a heavy oils consortium, the goal of which is to provide industrial guidance on development of SimSci-Esscor solutions that serve industry needs. The consortium will also foster the sharing of information and experience that will help validate Invensys solutions. Invensys will implement advanced solutions for heavy oils with each major release of PRO/II simulation software.
Supplementing SimSci-Esscor simulation and modeling capabilities for heavy oils are solutions from several other Invensys Process Systems' business units. The Field Devices segment, for example, is working on a Coriolis meter that measures 2-phase flow, eliminating the serious problems caused by entrained gas in heavy oils. The Manufacturing and Business Operations Management segment provides a variety of solutions such as production forecasting & scheduling and energy management, which deliver advanced analytical and optimization capability well-suited to the intricacies of heavy oils processing. When combined with its comprehensive process control and automation offerings, Invensys Process Systems can deliver a complete portfolio of solutions for the heavy oils market.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
