Table 3
Effect of pressure and temperature variations on predicted EACNlo values. EACNlo were calculated for two pressures (P1 = 200 bar and P2 = 500 bar) and two temperatures (T and T + ΔT, T is the temperature as indicated in Table 2 and ΔT = 100 K). αEACN (in EACN K−1) and βEACN (in EACN bar−1) denote absolute relative variations of EACN values resulting from ΔT and ΔP (ΔP = 300 bar), respectively
