Overview:

Visual MESA© is a steam system optimization and management computer program that was originally developed at Chevron and now marketed by Nelson & Roseme, Inc. Visual MESA is currently used at refinery and chemical manufacturing sites to optimize the overall site steam system and the parts of the electrical system that economically trade off with the steam system.

This paper will explore significant optimization variables and constraints commonly encountered in refinery steam system optimization, the strategies Visual MESA uses to deal with them.

Overview:

In general, refineries exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.

Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.

Overview:

This paper will not describe just all the features of the software or fully explain on-line optimization technology. The objective of this work is to present some interesting facts and lessons from the experience of implementing a cost based optimization program at thirty oil refineries and petrochemical complexes, around the world, since 1997. This paper will focus on the key optimization variables and constraints in steam system optimization, how they should be handled and how the human and organizational aspects can be addressed. 

Overview:

Industrial facilities where power and steam is produced (i.e., Cogeneration) exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.

Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.

Visual MESA was successfully applied to many industrial facilities worldwide, several of them operating steam and power generation networks of different complexity and capacity but all with energy cost savings. 

Overview:

This paper discusses real industrial examples in which the sitewide utilities system of refinery and petrochemical Sites are optimized with a real time, on line, industrially proven software. Experiences gained during more than 20 years of industrial projects deployed worldwide are commented (Refs. 1 to 10 are related to some recent projects). Main project steps are explained and critical details to be taken into account to assure successful use and proper technology transfer are presented. Specific case studies will be discussed in the paper. 

Overview:

Utilities and energy systems are often the major source of SOx, NOx and CO2 emissions, therefore, emissions control and the management of credits and quotas are tightly interrelated with energy management.

Overview:

Big and complex industrial facilities like Refineries and Petrochemicals are becoming increasingly aware that power systems need to be optimally managed because any energy reduction that Operations accomplish in the producing Units could eventually be wasted if the overall power system cost is not properly managed. However, process engineers always attempted to develop some kind of tools, many times spreadsheet based, to improve the way utilities systems were operated. The main drawback of the earlier attempts was the lack of data: engineers spent the whole day at phone or visiting the control rooms to gather information from the Distributed Control System (DCS) data historian, process it at the spreadsheet and produce recommendations that, when ready to be applied, were outdated and not any more applicable. 

Overview:

Utilities and energy systems are often the major source of SOx, NOx and CO2 emissions, therefore, emissions control and the management of credits and quotas are tightly interrelated with energy management.
In the case of refineries, chemical and petrochemical plants, energy represents the main cost (second to feedstock) and therefore its reduction has become a bottom line business decision. The energy systems at these sites are inherently complex, with the emissions cost analysis and limits compliance introducing an additional factor to the complexity of the energy costs reduction challenge.

Overview:

The energy systems, the steps for the implementation of Visual MESA and several features of the model are described in this article, with a focus on the use of the software for the calculation of energy-related KPIs. The EMS implementation project is discussed and the main conclusions relative to the reduction in operating costs are also presented.

Overview:

The aim of this work is to present a proposal for implementation of a support framework for abnormal situation management in the chemical process industry. A main feature of the technology developed is that it takes advantage of existing software packages that are familiar to plant engineers (e.g. Plant Information System) and a commercial process simulator. On the basis of three sources of information (a historical database, a HAZOP analysis, and a first principles plant model), the support framework is developed and easily implemented into the real plant. It consists of a preprocessing module, which performs a variety of key tasks using plant data such as data reconciliation, filtering, and denoising. Some of the outputs of this preprocessing module are the inputs of the fault diagnosis system (FDS). This FDS is a combination of a pattern recognition approach based on neural networks and a fuzzy logic system (FLS) in a block oriented configuration. The case study used to demonstrate the FDS implementation corresponds to a real petrochemical plant.

Overview:

Experiences gained during more than 20 years of industrial projects deployed worldwide are commented. Main project steps are explained and critical details to be taken into account to assure successful use and proper technology transfer are presented. Specific case studies will be discussed in the paper. Open loop vs Closed loop implementation is also presented.

Overview:

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

Overview:

The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux.

Overview:

From engineering to installation, commissioning, operations, and maintenance, FOUNDATION fieldbus offer significant cost reductions of 30 percent or more versus conventional analog systems. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.

Overview:

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

Overview:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Overview:

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Overview:

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

Overview:

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
