Structured packing has gradually become more prevalent in cryogenic air separation over the last 15 years. The need for high thermodynamic efficiency in the cryogenic distillation of the components of air (mainly argon, oxygen, and nitrogen) within an air separation unit (ASU) requires a large number of separation stages operating with small mass transfer driving forces. The pressure drop of ...

Solving Leakage Problems on Top-Entry Agitators
Top-entry agitator shafts on reactors, fermenters, crystallizers and similar machinery frequently cause sealing difficulties. Usually, the drive shaft is suspended from a coupling at the top, and terminates at the bottom inside the vessel.
The internal termination of the shaft creates an inherent maintenance problem: the lower bearing – if one ...

A chemical producer installs mechanical seals on its horizontal rotary vacuum dryer to maintain vacuum and increase productivity.
A chemical manufacturer produces two chemical compound resins as abrasive pastes that have to be dried to powders. The pastes each contain a different solvent and are dried separately at different temperatures in the same horizontal rotary vacuum dryer. The company ...

Vapour containment can be one of the most troublesome challenges in operating and maintaining process machinery. Aromatic hydrocarbons are a process ingredient for a vast array of materials, and evaporative loss of these volatile chemicals can be costly in many ways.
The simplest case is that evaporative loss is a direct expense: solvent lost to the atmosphere must be replaced – often at about ...
