  • Tank Blanketing in Hydrocarbon Processing Facilities

    During industrial manufacturing, many companies use a wide variety of chemicals from methanol, acetone and benzene to foodstuffs like wine and edible oils stored in large tanks at different points in the manufacturing process. In a technique called “chemical tank blanketing,” or “padding” nitrogen is commonly applied to protect chemicals stored in tanks against contamination, degradation or chemical change as well as to prevent fire or explosions. This white paper first discusses blanketing basics and benefits. It reviews considerations for tank blanketing  systems and discusses a newer approach, which is typically more  cost effective for most applications, is that of generating nitrogen on-demand in the plant itself.

  • Technology expands flowmeter capabilities, reduces costs

    Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.

  • The 7 Steps to ICS and SCADA Security

    The past two years have been a real wakeup call for the industrial automation industry. For the first time ever it has been the target of sophisticated cyber attacks like Stuxnet, Night Dragon and Duqu.

    In addition, an unprecedented number of security vulnerabilities have been exposed in industrial control products and regulatory agencies are demanding compliance to complex and confusing regulations. Cyber security has quickly become a serious issue for professionals in the process and critical infrastructure industries.

    If you are a process control engineer, an IT professional in a company with an automation division, or a business manager responsible for safety or security, you may be wondering how your organization can get moving on more robust cyber security practices.

    In order to provide you with guidance in this area, Tofino Security and exida Consulting LLC have condensed material from numerous industry standards and best practice documents. They also combined experience in assessing the security of dozens of industrial control systems.

    The result is an easy-to-follow 7-step process.

  • The Five Myths of Refining Precious Metals

    Precious metals are often present in hydrocarbon, petrochemical, and chemical catalysts. Techniques for recovering precious metals have been around for many years; yet many catalyst owners have misconceptions about how their refining organizations work.  In "The Five Myths of Refining Precious Metals", critical information is shared about the chemical processing industry:

    • Crucial aspects of weighing
    • Sampling and analysis of catalysts
    • Methods of catalyst recovery
    • What to look for in a proposal from a precious metals refiner
    • Understanding the cost of quality
    • How to ensure maximum precious metals return value
    • Environmental, ethical, and regulatory compliance issues

  • The Green Solution

    The ever present emphasis on technological efficiency is just one of several forces behind the pressure on companies to "go green" despite a trying economy. The ultimate criterion that determines whether a motor is truly green is energy efficiency. Technology, long the key to efficiency, can help resolve this issue.

  • The Perils of a DIY Distributed Control System

    The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.

  • Tips For Cleaning And Sanitizing Pneumatic Conveying Lines

    Pneumatic conveying is an effective form of moving dry materials. However, the long lengths of conveying pipe present a challenge when it comes to addressing cleanliness and sanitation.

    While the closed nature of pneumatic conveying systems protects material from outside contamination, like debris, insects, etc., it is difficult to identify and protect against internal forms of contamination, such as buildup, microbial growth, etc. A plant HACCP or sanitation plan that does not address thousands of feet of pipe and dozens of elbows is incomplete and at risk for a recall.

  • Tips On Controlling Dissolved Oxygen in a Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.
