Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.

Production Excellence

Production Management

  • MES integration
    A variety of individual systems that perform scheduling and other functions are included in the manufacturing execution systems (MES) domain. The connectivity among systems is a fundamental key enabler for agile production management.
  • Workflow standardization
    Production workflows should be defined and monitored for reliable production management. The standardization of workflows is especially effective at companies with multiple production sites. 
  • Real-time production management
    Overall real-time production management is required to speed up the production plan-do-check-action (PDCA) cycle.

Production Control

  • Loop tuning
    Process identification (PID) control plays a fundamental role in process control. Proper tuning is required for stable process control and is a prerequisite for advanced-level control. 
  • Advanced automation
    Advanced process control and knowledge-based navigation systems are key contributors to a well-automated operation.  
  • Real-time optimization
    Plant-wide optimization can be achieved with a real-time optimizer using rigorous model calculations.

Production Monitoring

  • Alarm rationalization
    An approach to alarm management based on the well-known engineering equipment & materials users’ association (EEMUA) No.191 guideline is recommended. Alarm root cause analysis is also an effective approach to successful alarm rationalization.  
  • KPI monitoring
    A wide variety of key performance indicators (KPI) should be monitored by each person. KPI monitoring requires comparison with targets and drilling down for detailed information.    
  • Production navigation
    Production tasks need to be managed correctly by the system. Task progress monitoring is a valuable bridge between planning and manufacturing that facilitates cooperation in production management.

Production Environment

  • Operator training
    Operator training systems allow operators to gain experience in handling various situations such as equipment malfunctions and in performing start-ups and other routine operations. It helps operators upgrade their skills.    
  • Control room design
    Control room design needs to take into consideration all aspects of the work environment including ergonomics, safety, ease of communication, functionality, automation of systems, and business policy.    
  • Resource optimization
    A central control room is desirable for an effective production environment. All production-related units should be stationed nearby to ensure good communication. In addition to centralizing the control room, the optimization of human resources and other activities can be considered to achieve production excellence.

Energy Management System Helps Refineries to Reduce Emissions and Energy Costs

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.

Use of Online Energy System Optimization Models

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.

Proposal To Speed Up the Implementation of an Abnormal Situation

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.

A Methodology for Batch Control Implementation - Real World Lessons

ISA S88.01 provides great benefit to users and vendors by solidifying batch operating models and standardizing batch control terminology. On the other hand, as befits an industry-wide standard, ISA S88.01 leaves great flexibility for individual users to apply their own project practices and implementation methodology. Even when utilizing ISA S88.01 models and terminology, many pitfalls remain for those who implement batch controls and recipe management without thinking ahead. Real-world project experience has demonstrated a number of design and implementation "lessons" which might be overlooked to the eventual grief of the batch engineer.

This standard depiction is based on the requirements of S88.01, technical report ISA-TR88.0.03-1996, user requirements, previous standards and commonly used procedure depiction methods in use today. PFCs can provide a common basis for the exchange of recipes, reduce the learning curve between control systems, and establish a common ground for improved human communication. This paper provides a brief overview of the development of PFCs, the rules for their use and some of the benefits expected by their adoption in the industry.

Automatic Adaptation of Batch Logic to Changing Levels of Field Automation thumbnail

Automatic Adaptation of Batch Logic to Changing Levels of Field Automation

As batch processes are automated, it is common to leave certain less essential field devices without automatic actuators. Thus, the initial control design must accommodate both automated and manual activities. Later, the manual field devices may be automated, either one-at-a-time or in related groups as equipment modules. These field changes, often occurring over a period of years, each require rework of the batch control logic, which can easily exceed the cost of the actuator. In response to this undesirable situation, a technique has been developed which permits the batch design to automatically modify itself, or evolve, to accommodate changes in field automation.

Production Performance Ratings

Key Performance Indicators (KPIs) are used in batch processing industries as measurements of production performance. Their use is one element in the current trend of real-time performance management. A single KPI used as the primary measurement of production can cause other dimensions of production performance lose importance. When multiple KPIs are used to measure a batch's production performance it can be difficult to reconcile differences between them for individual batches or for groups of batches. KPIs based upon meeting a target, or specification, measure absolute performance yet do not provide relative information regarding how a batch performed against its peers. The peer comparisons are important for monitoring variability of production performance, which is a critical factor in documenting ROI.
