The custom designed three-stage heat exchanger (photo) will be used to increase temperature of a 25,000 std. ft3/min airflow from 50°F to 330°F using 145 psig steam. Each stage is nearly 7 ft tall and 8 ft wide. Heated air…
Lysine (Figure 1) is an α-amino acid used in the biosynthesis of proteins. The compound contains an amino group and a carboxylic acid group. Under biological conditions, the amino group is protonated (–NH3+) and the carboxylic acid group is deprotonated…
Condition monitoring for predictive maintenance (photo) is a drive solution that focuses on status-oriented maintenance rather than traditional time-based maintenance. Status and drive data are recorded periodically or continuously via the programmable logic controller (PLC) output parameters and can be…
The MDM900 mill-discharge slurry pump (photo) is the latest addition to this company’s flagship Mill Discharge (MD) Pump Series. The MDM900 is designed for heavy-duty use in concentrator plants, where capacity and wear-resistance are essential. The MDM900 is an all-metal,…
The Turbex extractor (photo) helps to produce high-quality extracts from botanicals and natural products and to turn waste, such as orange peel or brewer’s spent grain (BSG), into revenue-generating nutrients. This patented extraction technology uses a series of rotors and…
Converting propane to propylene by oxidative dehydrogenation with CO2 is an alternative route to conventional propane dehydrogenation, but existing catalysts for this conversion are not very efficient. Now, in a study described in a recent issue of Nature Catalysis, researchers…
Driven by climate-related concerns, interest in hydrogen for its potential to play a significant role in decarbonization is surging. An increased urgency to get on track with decarbonization targets set by governments and corporations for the next few decades has…
Process hazards analyses (PHAs) are structured reviews during the engineering design process intended to detect potential hazards that were not addressed by the design team. This one-page reference describes commonly employed PHA methods. PHA methods PHAs are often conducted or…
Presented here are some practical points to help in the selection of a shell-and-tube heat-exchanger design for various applications Heat exchangers are widely used in various sectors of the chemical process industries (CPI), including: chemical; oil and gas; power generation;…
Light hydrocarbons in storage tanks can vaporize and vent to the atmosphere, creating harmful emissions. An optimized vapor-recovery unit can effectively and economically reduce such emissions In the chemicals, petroleum refining and natural gas industries, storage vessels are used to…
