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.
