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...
The resource intensive human activities (such as mining and extraction of mineral oils for betterment of life and modernization of society) have increased environmental pollution several folds. Products of mining and petrochemical industries are advantageous for the modern society. But waste generated such as BTEX from such industries are carcinogenic, toxic and causes adverse effects on enviro...
Background & Aims of the Study: One of the toxic pollutants in the wastewater of petrochemical industries is Terphetalic acid. In this study, the degradation and mineralization of Terphetalic acid in aqueous environment were studied by Ozonation and O3/ZnO processes in a semi batch reactor. Materials & Methods: This study is an experimental research on a laboratory scale. The st...
Introduction: Phenol is one of the aromatic hydrocarbons that exist in wastewater of various industries such as manufacturing chemicals, oil refinery and petrochemical industries. Because of its high toxicity and undesirable effect on organisms, its concentration control is essential in nature. The main objective of this study was to evaluate the efficiency of the Fenton oxidation process for t...
In this study, aerobic digestion of tannery industry wastewater was carried out using mixed culture obtained from common effluent treatment plant treating tannery wastewater. The effect of pH, temperature, inoculum concentration, agitation speed and initial substrate concentration on the reduction of organic matters were found. The optimum conditions for COD reduction was found to be pH 7 (60%)...
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...
