Random PackingRandom Packing has been used for separations in chemical and refining plants for many years. The practical, chemical process and commercial benefits of Random Packing are well-established in many applications and is one of the mainstays in the area of mass transfer equipment. For example at high liquid load and in high pressure applications, Random Packings are preferred by providing improved distillation or absorption efficiency and reduced pressure drop compared to other mass transfer contacting devices. Moreover, ease of replacement and suitability for storage make Random Packing the equipment of choice for systems with heavy fouling or corrosion.

Natural Gas Liquids (NGL) Treatment• Liquid-Liquid extraction service with amine solutions

• Random Packing decreases droplet size and increases dispersed phase hold-up while supressing back-mixing

• Sulzer Chemtech VSX liquid treater internals promote phase separation and redistribution

• A similar scheme using aqueous caustic as solvent is employed to remove mercaptans from the liquefied natural gas

Application

Butadiene• Divided Wall Column requires design and manufacturing skills for complex column internals

• Random Packing has proven to be a reliable mass transfer device for this extractive distillation with high risk of polymerization

Air Cooling Cl2/HCI/HF Absorption, Degassing, Water Treatment, Flue Gas Treatment• Plastic random packings show an excellent chemical corrosion resistance

• Are used preferably at low to moderate temperatures

• Plastic random packings are favored for their economic advandage
