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, todays 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.

Environmental Health and Safety Compliance in Biotech Companies: Common Deficiencies Encountered During Audits
Environmental health and safety (EH&S) compliance programs for companies that house laboratories are complex and not easily maintained. Even the most basic plan involves keeping a variety of permits up-to-date, performing regular employee training, conducting inspections, complying with a myriad of chemical storage and handling requirements, and keeping a number of contingency plans current and complete. This white paper identifies the most common pitfalls and four simple steps to keeping your EH&S program current.
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.

The fan repair and rebuild experts
Before you order brand-new air-moving equipment to replace your worn, corroded, unbalanced equipment, consider the potential benefits of repairing or rebuilding that equipment.
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.

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 its from the office or from the comfort of your own home. Todays 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.

Clean-in-place operation for thin-cake filtration technologies
This article discusses the choice of thin-cake (2 25 mm) separation technologies and their benefits to optimizing the effectiveness of the production process. The paper continues with a
discussion of clean-in-place operations to meet current Good Manufacturing Practices (cGMP) guidelines including riboflavin test and validations.
De-bottlenecking A De-iso-butanizer With VG-Plus High Performance Trays
To maximize a plants 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.
