  • 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.

  • Oxygen in cell culture/venting ozonated vessels

    This white paper outlines trends and opportunities for gasket standardization in processing plants ... including the potential for more reliable sealing, cost savings, inventory reduction, easier installation and safety practices. Steps are outlined for achieving success in gasket standardization across steel, glass-lined and FRP piping.

  • 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.

  • Process Moisture Analysis using FT-NIR

    Manufacturing a pure product can be critically important to the next steps in the manufacture of a powder-based product. As a result the removal of residual moisture and solvents from the crystallization, filtration and drying steps can be crucial to producing a stable product.

  • 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.

  • Guidance note for environmental safety instrumented systems

    Safety Instrumented Systems (SIS) are designed to monitor the process and control outputs to prevent or mitigate hazardous events. The design process strives for inherent safety, which is enhanced by applying multiple independent safety layers. Learn how to prevent accidents with prevention layers and minimise the consequences with mitigation layers.

  • 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.

  • Preventing Segregation During Powder Drying

    This 4-page case history by Jeroen van den Berg of Bolz-Summix discusses how changing process conditions within a conical screw dryer eliminated granulation and minimized product segregation.

  • 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.

  • 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 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.
