background heat, chemical and organic pollution are three types of environmental pollution, caused by refinery and petrochemical industries. problems caused by hear and chemical pollutants are currently resolved to some extent but organic pollution such as poly aromatic hydrocarbons (pahs) are still considered as important problems of industry and environment. objectives a laboratory study was ...

The world's increasingly voracious appetite for fossil fuels is driven by fast-growing populations and ever-rising aspirations for the lifestyles and standard of living exemplified in the developed world. Forecasts for higher electricity consumption, more comfortable living environments (via heating or cooling) and greater demand for transport fuels are well known. Similar growth in demand is p...

OBJECTIVE The purpose of this study was to compare thermal desorption tubes and stainless steel canisters for measuring volatile organic compounds (VOCs) emitted from petrochemical factories. METHODS Twelve petrochemical factories in the Mailiao Industrial Complex were recruited for conducting the measurements of VOCs. Thermal desorption tubes and 6-l specially prepared stainless steel canist...

the growing trend of the globalization process and how to deal with this phenomenon has become a major challenge for countries around the world in general and the developing countries in particular. the knowledge of comparative advantages and disadvantages of the home industries could be of great help to the countries trying to join the world trade organization (wto). in this article an attempt...

Recent application of photo-ionization (PI) coupled with GC×GC-HRTOF/MS for authentic standard mix called century mix along with several groups of petrochemical samples demonstrated PI as an effective soft-ionization technique to characterize volatile mixtures particularly, hydrocarbons [1]. This soft-ionization technology was shown to enhance analyte speciation by providing both molecular ions...
