Title:
NITROGEN GENERATOR
Document Type and Number:
WIPO Patent Application WO2004015347
Kind Code:
A3
Abstract:
A portable cryogenic nitrogen generator consists of an air preparation unit and a cryogenic distillation unit mounted inside separate standard-sized ISO containers that can be easily shipped to a drilling site and efficiently and quickly assembled into an operative state. The containers can be connected together at anchor points on the housings of both containers, making the nitrogen generator assembly more stable. The air preparation unit includes an absorption device and optionally includes one or a plurality of air compressor units. The cryogenic distillation unit includes a distillation column and associated heat exchangers. The air preparation and cryogenic distillation units connect through apertures in their respective containers and operate while being mounted in the containers.
