  • Special Report: Chemical Industry Sees Green

    For years the industry has been “talking green.” But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green? While pollution prevention was the original goal of green chemistry, today’s efforts promise to have a substantial economic impact. This Special Report will bring you up to speed on fruitful efforts to “go green” including an update on the growing interest in bio-based feedstocks.

  • IT Security for Process Control Using Siemens SIMATIC PCS 7

    Ensuring the security of industrial control systems is hardly a new topic. The earliest users of modern control systems in power stations and chemical plants saw the need to protect access to vital control functions from unauthorized use. Similarly, in industries such as fine chemical or pharmaceutical where “the process is the product”, manufacturers have always sought to protect the secrets of their unique processes from the prying eyes of industrial spies. This white paper by ARC describes how the Siemens AG PCS7 Security Concept bundles key security measures in seveal specific areas to create a deep hierarchy of security known as “defense in depth”.

  • Anticipating and Resolving Resource Overloads

    This white paper by Project Success Incorporated focuses on the resource that is of greatest concern to most organizations – personnel. In a project management system, personnel resources may be identified as individuals by name or as functional groups, such as computer programmers.

  • Why WirelessHART? The Right Standard at the Right Time

    The WirelessHART standard provides a robust wireless protocol for the full range of process measurement, control and asset management applications. Based on the proven and familiar HART protocol, it enables users to quickly and easily gain the benefits of wireless technology while maintaining compatibility with existing devices, tools and systems.

  • Design Considerations for High Liquid Rate Tray Applications

    Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.

  • Passive techniques for reducing input current harmonics

    Harmonics can have a detrimental effect on power generators and other sensitive electrical equipment for the user and utility alike. The number of adjustable speed drives (ASDs) has increased significantly in the past decade. Their contribution to the total electrical load of a power system is significant and cannot be neglected. This white paper discusses various passive techniques for reducing input current harmonics.

  • Rectifier design for fuel ethanol plants reduces energy

    Plants have traditionally used trays in the distillation columns to produce fuels grade ethanol. Trays of various configurations have been adequate in this service and their technology is well founded. The ever-present desire to reduce the energy needed to produce a gallon of ethanol has opened the doors to structured packings being used in the rectification sections of ethanol distillation columns.

  • Biodiesel Fuel From Palm Oil – Too Good to be Used as Fuel?

    The high prices for oil and gas have spotlighted other sources of fuel for internal combustion engines. Biofuel, a fuel derived from ethanol, and biodiesel fuel, a dieselequivalent derived from biological sources, are two possible substitutes for petrochemical fuel.

  • Applying ISA-S88 to Software Migration Engineering

    Dow Chemical maintains thousands of batch control systems world-wide built on its proprietary MOD 5 computer system. Over decades, they have been meticulous to preserve and enhance these systems. Dow intends to preserve and reap the rewards of this diligence by developing reverse engineering best practices and tools to migrate this intellectual property to next-generation platforms.

  • Managing Complex Equipment Status in a GMP Environment

    Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.

  • Securing Batch Control Systems

    Batch process control security is becoming a critical concern for the process control domain, IT technology infrastructure and the business enterprise. This paper explores several key security concerns in batch control system architectures and methods for addressing these issues.

  • White Paper: Internet Access in a Process Control Environment

    Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether it’s from the office or from the comfort of your own home. Today’s PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.

  • De-bottlenecking A De-iso-butanizer With VG-Plus High Performance Trays

    To maximize a plant’s performance, it is critical to fully understand the equipment being used, their mechanisms of operation, limitations and capabilities. This includes furnaces, exchangers, pumps, and mass transfer devices for distillation columns: fractionation trays, random and structured packing and associated liquid and vapor distributors. The purpose of this paper is to provide an overview of the key factors to successfully revamp with the goal of maximizing capacity without compromising efficiency.
