“…In this work the first component is always nitrogen and the second is the agent. Additionally, one additional set of bubble point data was found, [41] and interaction parameters fit for N2/R-1234yf. For simplicity, in the remainder of this document we will use the notation βT and γT where the first component is nitrogen and βT= βT,12 and γT = γT,12.…”

This report summarizes the results of work performed for US Army GVSC by the National Institute of Standards and Technology (NIST), Applied Chemicals and Materials Division on the development of a computer program for fire-suppressant bottle-filling calculations under interagency agreement number 11478007. The work includes the development of an Excel spreadsheet that is to be used with the NIST23 (REFPROP) to provide two bottle-filling calculations (1) given vessel size, mass of agent, mass of pressurizing agent, and filling temperature compute the filling pressure, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase, and (2) given the vessel size, mass of agent, and filling temperature and pressure, compute the mass of pressurizing fluid, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase. The agents

The isothermal experimental VLE data for the strong-zeotropic mixture of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) + ethane (R170) + tetrafluoromethane (R14) were measured using a circulation type apparatus at temperatures ranging from 253.15 to 273.15 K. On the basis of the UNIFAC (Dortmund) method, the new group volume, the area parameters, and the six binary interaction parameters of C2H2F, CF4, CF3, and CH3 were obtained by fitting the experimental data. Two theoretical models, the NRTL-RK model and the PR-WS-MUNIFAC model were used to correlate the experimental data. The AARD of pressure and the AAD of vapor phase mass fraction are 0.28%, 0.0077, and 0.0277 using the NRTL-RK model, and 0.32%, 0.0098, and 0.0185 using the PR-WS-MUNIFAC model, respectively. The isobaric VLE properties for the mixture were predicted using PR-WS-MUNIFAC model at pressures ranging from 0.1 to 2 MPa, and the three-dimensional phase equilibrium diagrams were presented. It is concluded that the temperature glide phenomenon is the most obvious at the mass fraction ratio of 0.35/0.1/0.55, and the maximum temperature glide reaches 73.4 K at the pressure of 0.5 MPa.

“…To examine the refrigeration cycle performance in depth and establish the optimal mixture composition, one of the most important basic strategies is the acquisition of vapor–liquid equilibrium (VLE) data. Many researchers have carried out experiments about VLE properties containing R32 and R218. − But no VLE data for the R32 + R218 mixture have been published. In this work, we focused on the R32 + R218 mixture, and the isothermal VLE of this binary mixture was acquired between 253.150 and 283.150 K.…”

The data for the isothermal vapor–liquid equilibria of a binary mixture of difluoromethane (R32) and octafluoropropane (R218) were obtained from 253.150 to 283.150 K using a vapor phase single recirculation. A model combining the Peng–Robinson equation, the modified Huron–Vidal two-order mixing rule, and the nonrandom two-liquid activity coefficient was used to correlate the vapor–liquid equilibrium data. The mean absolute relative differences of pressure (0.81%) and vapor phase mole fraction (0.011%) of the empirical results and the proposed model were calculated to evaluate its validity. According to the empirical and calculated results, azeotropic vapor–liquid equilibrium (VLE) behaviors can be observed.
