This paper presents the development of a real-time microsensor-based monitoring system that can be used to detect and characterize volatile organic compounds in soil and groundwater. The system employs an array of polymer-based microsensors (chemiresistors) packaged in a waterproof housing that is designed to protect the sensor from harsh subsurface environments, including completely water-satu...

This paper includes the significant on-site experience of the authors related to problems faced in amine systems with fresh amine and their possible solutions in phases#2&3 of South Pars gas                complex. The amine system was designed as a closed circuit system with the primary objective of removing H2S, CO2, and other acidic components from gaseous hydrocarbon streams. Amine plant op...

The title compound, [Zn(NCS)(2)(C(12)H(17)N(3)O)], was prepared by the reaction of zinc acetate with pyridine-2-carbaldehyde, 2-morpholinoethyl-amine and ammonium thio-cyanate in an ethanol solution. The Zn(II) atom is five coordinate with a distorted trigonal-bipyramidal geometry, coordinating with three N atoms of the Schiff base (2-morpholinoeth-yl)(2-pyridylmethyl-idene)amine and two N atom...

In the title compound, C(8)H(6)BrN(3)S, the thia-diazole ring is oriented at a dihedral angle of 48.35 (3)° with respect to the bromo-phenyl ring. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules.
