To defray energy costs, many industrial plants have their own boilers to generate steam in order to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels.

Reverse osmosis (RO) is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure.

Storage tanks are used in a variety of industries ranging from holding crude oil to holding feedstock for vinyl chloride monomer (VCM).

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.

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.

This article describes the tasks performed to develop and implement a real time, online model for energy cost minimisation and energy management at KNPC's MAA refinery.

After a description of the main project implementation tasks, the Real Time Energy Management System's (RTEMS) functionalities are described and the optimisation implementation procedures are commented on. Finally, several obtained results are presented.

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.

Process plants use different type of fuels, they often operate cogeneration units, their steam networks consist of several pressure levels, there are different types of energy consumers and there are emission limits to be observed. Import or export of electricity in deregulated markets, which could also be traded off with more or less CO2 and other contaminant gaseous emissions, increase the optimization problem complexity.

The Repsol YPF Tarragona Refinery operates a large, complex steam system. Utilities Optimization has been performed with an on-line computer based steam management program (VISUAL MESA) in order to make the Refinery more energy efficient and reduce steam system operating costs.

VISUAL MESA allows operators and engineers to:

1. Monitor steam production and use;
2. Optimize the production and use of steam, fuel and power in order to reduce 
costs;
3. Perform "what-if" studies, and
4. Audit the system with continually validated data. 
Nelson & Roseme, Inc. and Soteica Europe S.L. have worked with Repsol YPF Tarragona

Petronor is Spain's largest refinery, with a processing capacity of eleven million tons a year. Its energy system is large and complex, therefore the auditing and control of energy costs are a real challenge.
This paper describes the tasks performed together with Soteica, using a modern on line information and optimization system tools, to reduce energy costs.

A detailed model of the steam, fuels, electricity, boiler feed water and condensates systems has been built, including all the interactions between these systems, real plant constraints and degrees of freedom of their operation. Such a model is scheduled to perform automatic executions of the optimization of the entire system and is continually populated with validated live data from the process. A calculation of equipment efficiencies is done as part of the performance monitoring activity of the model. Other monitoring aspects include the continuous auditing of the energy system so the data can be relied on for evaluating the value of energy production and usage, and waste can be reduced or eliminated.

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. 

After a feasibility study, TOTAL decided to test an on-line model for site wide energy system management. TOTAL operates a large and complex energy system at Feyzin refinery. A detailed model of the energy system has been built and it is continuously fed with validated (not reconciliated), real-time data. It includes all the actual constraints of the site and decision variables for their operation. Continuous performance monitoring is also done, since the model writes back its results to the Real Time Data Base (Plant Information system). It also provides reliable data that helps to audit the energy productions and usages within the site energy system, and in that way wastes can be detected and eliminated.

An online steam management program can help refineries manage their steam and utility systems more energy efficiently and reduce their operating costs through optimisation and monitoring

Repsol Cartagena was the first oil refinery to be built on the Iberian Peninsula. It has an annual crude distillation capacity of 5.5 million tonnes, with two main areas of production: fuels; and lube oils, asphalts and paraffinic and aromatic oils. Repsol Cartagena is currently involved in an ambitious expansion project, whereby 22 new units will be built, increasing its refining capacity to an annual 11 million tonnes.

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.

This paper shows real industrial examples in which, with the existing equipment, continuous CO2 emissions reductions were achieved while optimizing the energy systems by using an on line model.
The importance of including the cost of CO2 emissions and how it should be taken into account when managing energy systems is explained. Furthermore, the optimization model is useful to perform case studies to evaluate energy system modifications taking into account this aspect.

A refinery energy system is modelled, including all the constraints, with continuous model validation using live data. Performance monitoring includes the tracking of equipment efficiencies by utilising validated data for its continuous calculation,

Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.

This paper shows how to improve distillation operations by focusing on procedure automation. It will review the importance of using procedures in distillation operations and highlights the collaboration work underway between Fractionation Research Inc. (FRI) and Yokogawa Corporation to improve procedural operations.

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.

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.

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.

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.

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. 

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.

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.

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.

This paper describes the tasks performed together with Soteica, by using an on-line model, to help achieve site wide energy costs minimization.
A detailed model of steam, fuels, electric, boiler feed water and condensates system has been built, contemplating all the real constraints and degrees of freedom for their operation. The electric power system is also modelled as it interacts with the steam production and usage. Such a model is continually validated with live data. A continuous calculation of equipment efficiencies is done as part of the performance monitoring activity of the model that is running as a service.

High volumes of volatile organic compounds (VOCs), typified by trichloroethylene and tetrachloroethylene, have long been used in various industrial fields for their high degrees of industrial usefulness. On the other hand, there is a growing awareness of environment preservation today, and of the fact that we face serious environmental pollution due to such harmful VOCs.

Migration of a refinery's DCS provided an opportunity to reconfigure and consolidate the control rooms and operational management system.

A Yokogawa ProSafe-RS safety instrumented system (SIS) will be the nucleus of a new fire and gas safety system at Shell's Clyde (NSW) refinery. The contract includes the control system, system engineering and installation and supervision.

In times of abnormal operations, systems are configured to produce lots of data – humans are not configured to handle or interpret them. However, when presented with the right information, in the right context, during an abnormal condition, humans are able to do things machines cannot.

Process automation in oil refineries is undergoing major changes, driven by customers frustrated by what they consider to be slow and incremental advances from the main automation original equipment manufacturers (OEMs) in the industry. ExxonMobil has become a de facto industry representative and is driving vendors like Yokogawa and others to reevaluate how large-scale automation projects are implemented.

Using wireless technology for monitoring a variety of measuring points in Industrial Plants has becoming a very attractive choice for plant managers. Today, the plant manager is able to build a quick and cost effective network solution to enable flexible information acquisition and to improve maintenance efficiency and safety.

Visual MESA Systems empower improved operational efficiencies in real time

Machines don't panic and they always do what they're told. But they can't think on their feet and can't react to situations for which they have not been programmed. Which do you want to depend on when your life depends on it?

CONTROL, January 2013

Standard Automation Methodology Improves Operations and Prevents Incidents by Enabling the Sharing of Best Practices Among Operators.

ARC believes that by implementing procedural automation, many process plants can minimize variability to help ensure smooth, efficient, and safe state transitions.

Machines can support humans when facing a stressful situation. Using a standards-based approach can reduce the likelihood of a problem escalating.

Assets and operations will have human-like learning and adaptive capabilities, allowing responses without operator interaction to situations within a secure, bounded domain.
