One of the biggest issues related to dust collection is compliance with U.S. Occupational Safety Health Administration (OSHA) and U.S. Environmental Protection Agency (EPA) regulations regarding combustible dusts and air quality. And as both agencies up the ante with tighter regulations and more scrutinizing inspections, it is imperative that processors make sure their facilities are meeting the standards...

Thermosiphon reboilers are the new standard in petroleum refineries and chemical plants. Nevertheless, approximately 50% of the world’s reboilers are kettles. In the realm of heat transfer, kettle reboilers have not been understood well. Last month, at ChemInnovations, however, Pete Parker, FRI’s president and my supervisor, cracked the knowledge barrier with insight from nothing other than...

Equilibrium stage simulations are the nearly universal process design tool for mass transfer columns that contact vapor and liquid in countercurrent flow. Whether the service is absorption, stripping, distillation, fractionation, quench or evaporation, equilibrium stage models make mass and heat balances easy. They quickly estimate stream conditions and physical properties. They are easily altered, so a...

  There are various reasons that make filtering necessary in processes. The raw materials might have impurities that require removal at the start of the process. After the initial mixing to produce the process slurry, the mother liquor could have solids that need a separation process. Unwanted solids could also form by a chemical reaction during the production of the process liquid. The nature of the...

I was having a “wallflower moment” after Ms. Ruth Sands’ excellent troubleshooting presentation at the March AIChE meeting. That presentation was well summarized by Editor in Chief, Rebekkah Marshall in the April issue of CE (p. 5). I wanted to tell Ms. Sands, and the other meeting attendees, about my solvents column troubleshoot. Here’s the story: On this particular troubleshoot...

Condensate pots are commonly used on the condensing sides of some reboilers, such as those that are heated by steam or refrigerant vapor. These pots provide a liquid seal that prevents uncondensed vapor from blowing out of the reboiler into the condensate system. A break in this seal can result in heat transfer losses. With steam reboilers, blowing vapor into the condensate header may also lead to...

Among the challenges of effective solid-liquid filtration is the accumulation of solids on the filter surface, which creates an increasingly dense mass that process fluid must push through. In many applications in the chemical process industries (CPI), a step-down filtration approach has the potential to avoid this difficulty, and at the same time, to cut operating costs and improve solution clarity. Even...

Engineers working in the chemical process industries (CPI) sometimes have to deal with aerosol contamination issues in which liquid-gas coalescers are routinely employed. For example, liquid-gas coalescers are used to protect compressors, liquid-gas contactors, turbines, low-NOx burners, metering and instrumentation stations, and for many other applications. Choosing the right coalescer type can be a...

Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time, and highly specialized crystallizer designs have been developed, especially in long-established industries. Solution crystallization is an important unit operation because the process can generate high-purity products from...

I have an ongoing dispute with a longtime colleague, Bob Miller. I said he ruined my new safety boots. He said he didn’t. Bob was a young, fearless distillation engineer at a time when our extraction engineer refused to take a trip to Japan to inspect new trays going into an old extractor. I called Bob into my office and asked him to take the trip, even with zero extraction experience. Bob accepted...
