Fiber-Optic Measurement Systems: Microwave and Radio Frequency Heating Applications

EOAF 12004160 65 66 67 68 69 70 71 Abstract Fiber-optic sensors do not interfere with electromagnetic fields and are commonly used to measure temperature and pressure used in microwave and frequency heating research and applications. This article introduces the physical principles for three different types of commonly used fiber-optic sensors and discusses important parameters to be considered ...

Sterilization of Foodstuffs Using Radio Frequency Heating

A study was conducted with a pilot-scale sterilization system based on 27-MHz radio frequency (RF) energy to investigate the effectiveness in shortening process time and in improving quality for foods sealed in 6pound military-ration polymeric trays. Chemical marker M-1 was used to evaluate heating uniformity in 20% whey protein gels as a model food, and macaroni and cheese was processed to ass...

The Viability of Oil Extraction from Trinidad Tar Sands by Radio Frequency Heating: A Simulation Approach

Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...

Radio Frequency heating for oil recovery and soil remediation

The paper presents basic principles of RF heating and describes its possible applications for oil extraction and soil remediation, based on the experience obtained by several years of work at Consorzio Polo Tecnologico Magona (CPTM). Activities include a complete approach, which goes through the steps of problem formulation, modeling, and experimentation. It is shown that RF heating can represe...
