Since this work was reported, resin manufacturers have made improvements in HDPE materials and new grades of HDPE have been developed that have improved modulus values. The authors conclude that HDPE is suitable for use up to at least 40☌ (104☏) in hydrocarbons, and possibly up to 60☌ (140☏) in well-controlled, fully understood applications. This is consistent with known properties of HDPE exposed to liquid hydrocarbons. The authors reported that the maximum swell was about 6% and the maximum weight gain was about 10%. It is clear from these measurements that there are useful properties at 60☌ (140☏) for this particular HDPE grade. 3.1.1 Molar mass (M) and ideal gas specific heat capacity For problems such as the simultaneous process and working fluid design of Organic Rankine Cycles, however, these transport properties act strongly on the objective function ( Lampe et al., 2012). Transport properties do not enter the case study presented below and the inclusion of transport properties into the CoMT-CAMD methodology is therefore not detailed here. We use Quantitative Structure Property Relationship (QSPR) methods for this purpose.Ĭorrelating transport properties, such as shear viscosity, is subject of our current development with very satisfying results. Since the CoMT-step optimizes a hypothetical molecule entirely characterized by solvent parameters of the PC-SAFT model, it is necessary to estimate these properties based on the solvent parameters. Examples are the molar mass, the ideal gas heat capacity or transport properties. #F MOLAR MASS FULL#To allow for a full process optimization within the proposed CoMT-CAMD method, physical properties beyond the standard properties accessible from the PC-SAFT model are required.
