The format of each BIP line is: BIP type sec-ID BIP-A, [BIP-B, BIP-C, BIP-D, etc] The BIP type must be one of the following: NRTL PR (Peng-Robinson) SRK (Soave-Redlich-Kwong) UNIQUAC WILSON BWRS ESD SAFT Valid names are listed in the BIPNAMES.SF file in the system directory. The BIP sec-ID is the secondary ID for this BIP data. Associated with each set of BIP values are, of course, two components; the primary component and the secondary component. The BIP keyword must be included somewhere between a pair of STRC and ENDC keywords. The STRC and ENDC keywords define a group of lines pertaining to the same component and it is assumed that this component is the primary component. The BIP sec-ID is the secondary ID associated with this BIP data and is the CHEMCAD ID number for the secondary component. You can specify any secondary ID so long as it is numerically less than the primary ID. For example, the following BIP line specifies values for WILSON BIPs between a user-added component and water (CHEMCAD ID for water is 62). BIP WILSON 62 -52.605 620.63 If the current group of lines in your neutral file pertains to component 8001 and you include the following line in this group, it would be discarded because the secondary ID is greater than the primary ID: BIP WILSON 8005 -52.605 620.63 [invalid data] The order in which you specify the BIP parameters is important. You must specify at least one BIP parameter. The maximum number of parameters depends on which BIP type you are specifying. The BIPNAMES.SF file in the system directory includes the maximum number of parameters that can be specified for each BIP type. The order in which you specify BIP parameters is also important. The following list indicates the correct ordering for each BIP type: BIP NRTL secID Bij, Bji, alphaIJ, Aij, Aji [maximum of 5 parameters] BIP PR secID Bij [1 parameter only] BIP SRK secID Bij [1 parameter only] BIP UNIQUAC secID Aij, Aji, Uij, Uji [maximum of 4 parameters] BIP WILSON secID Aij, Aji [maximum of 2 parameters] BIP BWRS secID Kij [1 parameter only] BIP ESD secID Kij, KTij, KaLin, dHLin, KaBin, dHBin [maximum of 6 parameters] BIP SAFT secID Kij, KTij, KaLin, dHLin, KaBin, dHBin [maximum of 6 parameters] 查看更多1个回答 . 2人已关注
