Question:  What standard, guideline or regulation should I use to create a cybersecurity program, or should I wait until a standard is finalized? Answer:  Waiting until a cybersecurity standard is explicitly selected, accepted and enforced is a mistake for two very good reasons.  First, a security program is much more social and cultural than technical. One thing we’ve learned from the...

Question:  Besides rotary, fluidized-bed, and flash dryers, what other types of dryers can remove moisture and other volatile compounds from bulk solids? Answer:  For many applications, an efficient and cost-effective alternative is to dry the bulk solid in a silo equipped with heat exchangers or modified to permit injection of a gas. Compared to other dryers, drying silos have several...

Question: How do rain, snow, ice and fog impact wireless performance? Answer: In the process of distributing wireless to a geographic area, it is often necessary to place transceivers outdoors. In doing so, a prudent designer understands that one cannot afford to overlook the effects of the environment on the life of the equipment and the performance of the wireless system. The major environmental effects...

Question:  Should we convert from manual dumping of sacks to discharging from bulk bags?    Answer: Dry, bulk chemicals have long been purchased in 50-lb (23-kg) paper and plastic sacks for several reasons. In volumes smaller than rail and truckloads, sacks were often the only packaging in which to purchase many such products. Sacks also enabled plant personnel to physically lift, slit and...

Question:  Is  wireless ready for control?    Answer: The IEC 62591 (WirelessHART) standard was designed for both control and monitoring from the very beginning.  However, users wanted four key pillars in place before putting theory into action. Proof of comprehensive wireless system security, redundant systems, faster device scan rates and proven field experience were required...

Question: How are hydrocarbons best removed from water? Answer:  First, the type of hydrocarbons present must be identified. Typically, the hydrocarbons in question are in the form of oil or an oil-like substance. In that case, the miscibility of oil will have a major influence on the process used. If the oil is immiscible in water and the droplet size is large, the droplets will probably rise rapidly...

Question:  What is driving the trend toward increased water reuse and how is membrane technology addressing this? Furthermore, what does the future hold for water reuse? Answer: Meeting water demands and ensuring a plentiful supply of water for future generations is a top-of-mind issue for the water industry today. Adequate, safe and accessible water supplies are essential to sustaining life and...

Question: What is the RF spectrum and what considerations regarding it do we need to take as we expand our implementation of wireless networks? Answer: There is an extremely important asset that you own and control. However, if you don’t manage this asset effectively, it could turn into your greatest liability. This asset is your airwaves — the radio-frequency spectrum that is available in...

Question:  What can we do to prevent caking? When our powders are packaged into bags at our plant, they appear to be free of agglomerates.  However, our customers report that when the bags are opened at their facilities, they observe an excessive amount of caked material.  This results in rework and potential losses in sales.  We suspect that moisture is the cause, but our bags include...

Biodiesel, the methyl ester of fatty acids, has been accepted as a renewable-sourced alternative to fossil-derived diesel fuel. Today in many parts of the world, biodiesel is already blended with diesel fuel up to about 5%. Presently the demand for biodiesel is only approximately 40–50% of the production capacity, but the global biodiesel market is expected to experience strong growth in the next few...

Question: What are the top considerations I need to take into account when planning for control over wireless? Answer: The prospect for control over wireless is one of the manufacturing industry’s hottest topics, but it’s important to realize that it’s not an appropriate solution for every application. Plants should consider three key factors when evaluating whether control over wireless...
