#achema2018 - “Jack of All Trades is the Master of None”, is what they often say. But, have you ever met the “Master of All Trades?” At Sulzer, a multinational and diverse team of dedicated, young professionals is making both the ends meet, in order to establish their influence in the field of mass transfer.

Ranging from column internals (trays, packings, weirs and downcomers) to crystallizers, Sulzer promises to be a “one-roof solution” for all your mass transfer queries. The umbrella valve tray, an excellent example of elegant engineering, boasts of all the perks associated with a bubble cap tray but also overcomes the loopholes associated with it. This fact has rendered this type of tray indispensable for majority mass transfer operations. It can be operated with a low pressure drop and thus, the usage of this tray doesn’t hamper the hydrodynamics of the column. In addition to this, it is also suited for lower duties of the feed.

The rotating disc contactor employed for extraction presents a prudent picture of perfection. The extraction unit operating with a rotating disc contactor is mounted in a skid system and has a built in solvent recovery unit in order to get out the best from the process. Such extraction units are common in recovery of phenol from waste water as direct separation of phenol from water by distillation isn’t possible. The extraction is subsequently followed by a wastewater water stripper which removes the solvent form the waste water stream. The built-in solvent recovery system promises efficient recovery of solvent form phenol. Flexibility and integrated solvent recovery has made this unit an apple of the eye of the stalwarts in the chemical industry.
