摘要

在美国，环境保护局已就推定最大可用控制技术提出了临时建议。其中两种选择--变压发泡（V.P.F.）和液态 C02 喷射工艺--在以下基础上进行了比较：V.P.F. 和液态 C02 均符合《蒙特利尔议定书》的要求。比较结果表明，液态 C02 是解决环境问题的部分方案，而 V.P.F. 则是更全面的方案。

Comparison of the VPF and Liquid C02 Foaming Processes

A number of technologies are now available to replace ozone depleting chemicals and hazardous air pollutants in the manufacture of flexible polyurethane slabstock.In the U.S.A. the Environmental Protection Agency has made provisional recommendations regarding the Presumptive Maximum Available Control Technology. Two of the options - Variable Pressure Foaming (V.P.F.) and the Liquid C02 Injection process are compared on the following basis: Production Range; Economics of Production; Process Improvements; Environmental Considerations; Capital Costs Both V.P.F. and Liquid C02 fulfil the requirements of the Montreal Protocol.The comparisons illustrate that Liquid C02 is a part solution to the Environmental problem, V.P.F. is the more complete solution.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
