Hadron energy reconstruction for the ATLAS calorimetry in the framework of the non-parametrical method

2002

This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillator hadronic part) in the framework of the non-parametrical method. The non-parametrical method utilizes only the known $e/h$ ratios and the electron calibration constants and does not require the determination of any parameters by a minimization technique. Thus, this technique lends itself to an easy use in a first level trigger. The reconstructed mean values of the hadron energies are within $\pm 1%$ of the true values and the fractional energy resolution is $[(58\pm3)% /\sqrt{E}+(2.5\pm0.3)%]\oplus (1.7\pm0.2)/E…

Corrosion in alcanolamines for natural gas treatment - High temperature experiments in lean and rich conditions

2011

International audience; In the oil and gas industry, acid gas removal is required for the treatment of natural gas. New applications were also recently pushed forward for CO 2 capture from the flue gas of power plants. For both applications, the most widespread industrial processes use absorption-desorption by an alcanolamine solvent. In such amine units for acid gas removal, corrosion represents an important operational concern. Influent parameters governing corrosion are temperature and acid gas loading, amine nature, and the presence of degradation by-products. Some of these parameters were studied with corrosion experiments in autoclave. Test temperature was between 110°C and 120°C, i.e…
