Core Technology

Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired eductor which is the core technology of the PRR system is presently being used commercially on a cruise ship at a scale of 5 TPD. The capabilities of the PRR technology have been demonstrated in a pilot plant, at a rate of up to 2 TPD of various types of waste. Because of the high intensity of the plasma flame and the reduced amounts of gases produced in a gasification system, compared to traditional combustion systems, the PRR system is typically very compact. As such, the PRR technology opens the door for a decentralized, small scale approach to waste management.

Internet technology continues to grow fast and has now become the dominant computing technology in developing software and computing applications. By fully taking advantage of the quick development of the service concept and modeling, Web services technology, as part of Internet technology, has rapidly evolved and made a drastic impact on enterprise integration. A deployed Web based service, relying on a suite of Internet based standard protocols, is self-contained, self-describing, and network-neutral computing component. It can be readily deployed, published, located, and invoked over the heterogeneous networks. This chapter starts with a brief introduction to the concepts of services and enterprise service computing. The Web service’s technical fundamentals are then fully explored. XML, SOAP, WSDL, and UDDI as the core technologies are further explained in great detail. Implementation examples are finally used to demonstrate how the Web services technology can be typically applied in integrating distributed applications across an organization.
