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...

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...

An industrial complex specially located in coastal area seriously affect on air quality near residential area. Gwang-yang bay, where is the southern part of the Korean Peninsula, is one of the densely accumulated industrial areas. And air pollution over the area also increase with the density of industrial complex. Since petrochemical industry occupied major part of the Gwang-yang bay complex, ...

The objective of this paper is to design a real-time control solution for chemical processes, namely the ethylene reactor, the key-installation in the petrochemical industry. The controller used is lag or lead controller, a simple yet suitable control tool. This article deals with the problem of finding all first order controllers that stabilize a given LTI continuous time or discrete time plan...
