\r\n
\r\nIndigenously developed highly efficient structured packing modules and distillation column sections for operations involving separation of mixtures of very close boiling species
\r\n
\r\nSystem is economical import substitution and embodies the “Make In India” philosophy
\r\n
\r\nLarge interfacial area (700 m2/m3) for efficient mass transfer, low HETP (5-7 cm), high wettability, high voidage (>92%), low pressure drop characteristics (4 mm Hg/m packed height at 1400 kg/h vapour flow) at par with international suppliers
\r\n
\r\nSuccessful operational experience of these columns in critical applications in the nuclear industry for over 40 years
\r\n
\r\n Each upgrading column being used at Indian PHWR site has a total of 238 such modules packed into 14 sections of 1.05 m diameter.
