The VS pneumatic vacuum-conveying system (photo) automatically transfers bulk materials in a choice of lean or dense phase using the same conveying system. Featuring a designed-in ball valve in the feeding elbow, the conveyor can be operated in dense phase…
Small-scale distillation processes have specific concerns that are different than commercial-scale distillation. Presented here are several topics, including column internals and column-sizing software, considered from the perspective of pilot-scale distillation The design and operation of laboratory- and pilot-scale columns are…
This company’s custom mixing systems (photo) are engineered to optimize unique processing projects, including batch size, material properties, agitation levels and more. Engineers can develop a mixing system that includes mixers and tanks from simple open-top designs to full ASME…
The Fisher Fieldvue L2t liquid-level controller pairs with an electrically-actuated control valve to reliably maintain ideal separator levels. Compared to alternatives using electric on-off valves, the new Fisher controller makes it possible to save significant energy and maintenance costs by…
Launched last December, the High Efficiency Scrubber (HES) Optimizer (photo) is a digital tool that combines internal process calculations with measurements available at site to enable energy savings in the operation of Venturi-type scrubbers in wet-gas cleaning plants. Although the…
This company recently received FM approval for its Rack Fire Protect (RFP) non-occupancy buildings. Fire rated for 2 hours at 2,192°F, they minimize the risk of fire spreading, making them suitable for the storage of flammable chemicals, lithium-ion batteries and…
Understanding the water chemistry is a first step in preventing heat-exchanger fouling At the two power plants and chemical plant in which this author formerly worked, the fresh-water-makeup supplies (two lakes and an underground aquifer adjacent to a river) all…
Reactors are at the core of most processes in the chemical process industries (CPI) and are broken down most broadly by whether their operating mode is non-flow (batch) or continuous. Each reactor type has advantages and disadvantages depending on the…
A laboratory ventilation system that does not work effectively may not keep personnel safe and can produce significant adverse impacts on operations Laboratory personnel treat their ventilation systems as a given. They expect them to be designed right, to always…
The new SLPX Series of sloped-top motor disconnects (photo) enable plant operators to more easily prioritize sanitation while meeting requirements for multiple disconnects. Available in three multi-gang enclosure sizes, the stainless-steel SLPX Series features a unique clean design for critical…
