Compact ship process

In a typical process the finely divided dry crystals are compacted under heat and pressure in a roU press into briquettes having a density of 1.550 to 1.590. The briquettes are passed to a rotary screen where the fins, thin layers of material attached to the periphery of the briquette centerline, are removed and reprocessed. The finished briquettes pass into large storage bins from where they are loaded into rail-hopper cars or shipping bins or packaged into dmms and other shipping containers. 

Plastics recycling using the selective dissolution process can function with possibilities (iii) and (iv). Plastics collected locally would be shredded or compacted at or near the point of collection. They would then be shipped in bulk, typically by rail or water, to central sites for processing. The use of relatively few central sites would give good economies of scale and would allow the plants to be located where chemicals and plastics are now made. Selective dissolution is a chemical process which is yet another stage in the transformation of the original feed stock. It is therefore unreasonable to expect them to be recycled by strictly mechanical means. 

In addition to the various industries and uses identified for sonar and sound waves, the application of sonar helps to support and encourage research in a significant number of other industries and scientific fields. Power for sonar systems is vital, but space on ships or submarines is limited, so sonar development drives the pursuit of compact power sources. The effectiveness of the sonar depends on the power and focus of the beam produced by the transducer, which in turn promotes the exploration of more efficient and effective transmitting materials, as well as means of recognizing and collecting the return beam. The need for small computers to process the return data has created the demand for compact computer processors and data storage. 

The offshore oil and gas sector, be the plants used by the industry necessary to extract and process the fluids located on ships, platforms, down pipes or under the sea bed, was one of the first to embrace process intensification with compact heat exchangers such as the PCHE. The sector has pioneered other PI uses in separations and more recently in reactions, and the potential for growth and further innovation is considerable. More extensive replication onshore, as the demand for these resources continues to grow, is likely.
