Real Life Application
Case study – Liquid Nitrogen Use
A user of liquid nitrogen (LN2) for cooling multiple GC (gas chromatograph) Cryotrap, piped liquid nitrogen throughout the facility using vacuum jacketed (VJ) pipe and a keep full device. Unfortunately for them, the system had not been designed correctly and they were wasting 50% of the LN2 delivered. With some minor modifications, the system was returned to its normal use at savings in excess of 10,000 gal of LN2/mo. LN2 is used for freezing food, thermal chambers, among many other applications.
Case study – Hyperbaric Oxygen
A medical hyperbaric application was using ~1300 gal/mo of liquid oxygen, as a gas. However, there were several opportunities to save wasted gas by the addition of some different design equipment. By reengineering the storage system type and design, savings of ~50% was achieved.
Case Study – Tank Blanketing
A plant was using nitrogen to blanket flammable storage tanks. The customer was originally having flow problems during purging and withdrawal operations. After engineering analysis of the system and review of the piping system several recommendations were made that eliminated the flow problems and achieved savings of 75% of the consumption.
Case Study – Equipment Type and Size
A manufacturer was using cylinders and small liquid containers due to the infrastructure costs to go to a larger container. After providing project cost and engineering analysis of the system, it was proven that the savings in product price, lost product, and decreased labor costs (not considering potential accidents due to moving heavy containers) would pay back the infrastructure costs in 6 months.
Case Study – Incompatible Materials
A plant owned, cryogenically operated oxygen storage system was requested to be reviewed for correct design. The results determined incorrect materials of construction for cryogenics temperatures and incompatible materials for any oxygen systems. Although a catastrophic event did not occur, the potential was very real. The cost for the new parts were less than $200 to repair.
Case study – Pipeline Not Delivering
A customer called to complain about discoloration at the cutting edge. After an engineering analysis of the entire system from storage vessel to the laser, several undersized areas within the system were identified and changed. In addition, the tank modifications were needed as well to assure the storage pressure was maintained.
