The Beijing Spectrometer (BESIII) [1] is a high precision general-purpose detector designed for high luminosity e + e − collisions in the τ-charm energy region at the Beijing Electron Positron Collider (BEPCII) [2].At BESIII, the current end-cap time-of-flight (eTOF) detector consists of 2×48 fast scintillators (EJ204) readout with fine-mesh …
WebQuestion: Use vapor pressure data for CO2 and critical data to determine the value of its acentric factor. Compare the value you calculate with that from Table A-2 in the text. Note that when interpolating vapor pressure data, one is much better off assuming that the data are correlated by the relation In(Pg)=(A/T)+B than by using a linear interpolation. WebJan 23, 2024 · C2F4H2: Boiling point at Patm-0.5°C-26°C: Vapour pressure at 35°C: 2,3 barg: 7,9 barg . From a technology point of view, the operating conditions are easier to achieve for butane, and butane is classed as a “green” solvent. The use of butane, however, generates an ATEX zone.
