Conversion of Nitrogen Plant to Oxygen Generation at L.G. Rotary Hospital, Vapi
Transformation of a PSA-based nitrogen plant into an oxygen generation system at L.G. Rotary Hospital in Vapi. The process involves utilizing PSA technology with a specific operation philosophy, molecular sieve types for O2 and N2 generation, and various modifications to adapt the plant for oxygen production. The installation by M/s UPL was completed within 72 hours, showcasing efficient and effective implementation.

Conversion of PSA based Nitrogen Plant to Oxygen Conversion of PSA based Nitrogen Plant to Oxygen Generation Generation ( (An installation by M/s UPL at L G Rotary Hospital, Vapi) ) 1
PSA Technology: Operation Philosophy PSA Technology: Operation Philosophy Compressor for generating the pressure of feed air at 6 barg Tower A & B : filled with Alumina (water removal) & Molecular sieve Each tower working for 45 sec for generation of O2/N2 and 15 sec for re-generation Buffer tank to maintain the constant pressure at supply side during change over Gas sensor for continuous monitoring of O2 or N2 quality at supply side Discharge O2 or N2 at constant pressure of 4.5 barg 2
Type of Molecular Sieve & Usage Type of Molecular Sieve & Usage O2 Generation: Zeolite Molecular Sieve N2 Generation: Carbon Molecular Sieve 3
List of Modification : From Nitrogen to List of Modification : From Nitrogen to Oxygen Generation Oxygen Generation Molecular Sieve Changer over from Carbon to Zeolite & Activated Alumina Oxygen analyser for quality monitoring 2 stage filter for dust removal at outlet (1 micron and 0.1 micron) Control Panel program modification/ replacement On-Off valve installation for automatic change over Limitation of N2 Plant to O2 Production Spare Nitrogen Plant availability at Industry Nitrogen or Oxygen can be produce at one time and can t change over without above modification 4
