Storage system design problems

The main problem in the system design is the heat and vapor transport in and out of the adsorbent. Advanced heat exchanger technologies have to be implemented in order to keep up the high energy density in the storage, which would be reduced by the amount of inactive heat exchanger material. 

During the last decade, the fascinating phenomena of the photochromic effect became a hot problem of molecular structure and spectroscopy due to its promising application in the design of new memory storage systems at the molecular level. This phenomenon has been discovered and studied in several nitrosyl complexes of transition metal ions [1-6]. At low temperatures, the most extensively studied sodium nitroprusside Na2[Fe(CN)5(NO)] 2H2Q (SNP) demonstrates two excited... 

The intentions to improve the environment were noble, but the simple vent system design possessed an unrecognized flaw that allowed a minor overfill situation to suddenly and completely destroy the vessel. The acid tank project was rather simple, so the proposal was accepted and no one asked pointed questions like, What happens if the acid storage tank is overfilled by a tank truck (As we shall see, many unforeseen problems have occurred on equipment so simple that a detailed examination of the proposal may have been considered unnecessary in years past.)... 

Some applications of cryogenic-fluid transfer require optimization of many aspects of transfer-system design. This study examines methods of transfer-line insulation, the problems of metal degassing, and line storage life. 

This chapter will consider various insulation concepts used in such storage systems and briefly review the basic design approach used for conventional storage vessels and transfer lines. The accompanying problems of cooldown and two-phase flow encountered in the operation of these cryogenic systems are included in the discussion. 

Many factors must be considered when designing a warehouse storage system. If the wrong choice is made in laying out storage racking, this error can be corrected before operations begin. If the sprinkler system is in error, it may take a fire to reveal the problem. At this point it is too late to correct the error and a serious fire loss may occur. 

The installed capit investment is about 375 per pallet for a 5000-paUet system. A characteristic of drive-in, drive-through, and flow racks is that, at any one point in time, only one product can occupy a given storage lane. Products are not mixed because of the complications that this practice presents in inventoiy management. In any event, there is seldom any need to mix products in the chemical industry because products are made in lots, blends, etc., and a storage lane is ordinarily designed to accommodate either a complete lot or some fraction of a lot. The result is that the total storage space available rarely is completely used. This is a problem that aisle racks...
