A Non-Metallic Answer to Corrosion Problems

Corrosion is a most expensive by-product of industry. It is a fact that corrosive solutions and fumes deteriorate plant equipment at an annual rate in excess of 6 billion dollars. All companies are continually seeking new ways to decrease maintenance cost and down time. Paper published with permission.

Bulk Storage of Dried Citrus Pulp

Bulk storage of dried citrus pulp at Plymouth was first considered because our customers, many of whom have been buying our pulp for 15 years, were adopting feeding systems which fitted bulk feeds, and because bag and bag dumping costs seemed to provide a source for sizeable savings.

A New Approach to Evaporation

The ever growing need for the removal of water from solutions has brought forward the development of many new techniques. As the state-of-the-art has become more sophisticated, specialist designs have been evolved to cater for particular requirements. Paper published with permission.

Recovered Volatiles From Citrus Juices

In the early production of frozen concentrated orange juice (FCOJ) several factors contributed to a product quality that closely resembled the fresh juice fed to the evaporator. Among these were: fruit selection, a moderate juice yield, no heat treatment, low evaporator temperatures, cutback juice (8)2, and selected coldpressed orange oil (7).

Fluidics: A New Tool for Controls

This paper discusses the principles which form the bases for the phenomena usually referred to under the common heading of “Fluidics.” It explains how these phenomena can be used to obtain desired results, gives a few examples and points out some of the advantages and disadvantages of Fluidic devices.

Considerations for Air Power Systems

The availability of compressed air in plants today is viewed by many as being in the same category with electricity, water and gas. The one major difference, however, lies in the fact that for most industrial plants compressed air is generated within the plant proper and the compressor and related equipment is maintained by “In-Plant Personnel”, while electricity and its related generating equipment and clean water and its related purification and pumping equipment are supplied from outside facilities and maintained by others. The difference thusly becomes clear. In the case of compressed air, the air compressor and related accessories represent a capital investment on the part of the user, while the other services (electricity, water, gas, etc.) are essentially services paid for on a usage basis and charged as a monthly cost of operation. Although there is a difference as to the source of the utility, compressed air being considered as such is expected to be every bit available in sufficient capacity and pressure by plant management as are ampers and voltage in the case of electrical power or gallons of pure pressurized water. This difference requires the watchful eye of plant management and maintenance personnel, for, unlike the other utilities, the compressed air source and usage is their complete responsibility and not that of the local utilities.

Measuring Stack Particulate Matter Emission

There are many aspects of air pollution: medical, political, sociological — all of which are becoming increasingly a subject of public concern, and quite properly so — for, while it is possible to filter and purify water before drinking it; we must breathe the air just as it comes to us, pure or not pure.
