2Introduction<strong>Linde</strong> Cryo<strong>Plants</strong> Ltd. is a subsidiary of The <strong>Linde</strong>Group based in UK.The <strong>Linde</strong> Group is a world leading gases andengineering company with more than 52,000employees working in around 100 countries.<strong>Linde</strong> have supplied more than 3,000 air separationplants and maintain the highest standardsof service.Comprehensive services that ensure a highlevel of client and customer care include:- A world-wide network of <strong>Linde</strong> offices oragencies- Teams of plant designers and consultants- World-wide aftersales services- Erection and start-up services- Full product training- Plant maintenance contractsConceptThe <strong>GAN</strong> range of nitrogen plants are pre-assembledmodular systems offering safe, reliableand easy operation. The plant’s design providesflexibility to meet the needs of individual usersof nitrogen gas. When needed liquid nitrogenoutput is available to meet either a regular demandfor liquid nitrogen or a need for strategicreserves of nitrogen product.<strong>Linde</strong> Cryo<strong>Plants</strong> Ltd. design and manufacture arange of small and medium sized containerisedcryogenic air separation plants that provide highpurity nitrogen to the oil and gas industry.The highly adaptable design of <strong>GAN</strong> plants isthe result of over 100 years of <strong>Linde</strong> experiencemaking them the first choice for industrial usersneeding on-site, cost effective nitrogen gas.- Oil and Gas- Petrochemicals- Pharmaceuticals- Synthetic Fibres- Electronics- Float Glass- Metallurgy- Breweries- FertilisersInternal container image forMINI<strong>GAN</strong>, <strong>GAN</strong> and LOX

Air thenpasses into the coldbox where air is cooled,liquefied and distilled to yield pure nitrogengas product.
