The UNIT SIG hed a conference call today from 4:30 pm till 5:40 pm Central European Time.

Agenda: progress the Petroleum Fractions interface specification, especially on the textual requirements pertaining to interactions between PME and Property Package.

Participants: Krishna Murthy PENUKONDA (Schneider Electric), Jasper van BATEN (AmsterCHEM), Richard SZCZEPANSKI (KBC AdvancedTechnologies), Michael HLAVINKA (BR&E), Michel PONS (contractor for CO-LaN as Chief Technology Officer)

Outcome: started back with the question raised by R. SZCZEPANSKI about the possible need, in order to avoid confusion, to name differently a property when it is a Petroleum Property and when it is a Compound Constant. CriticalTemperature was used as an example. This question arose in the midst of formulating additional requirements pertaining to properties such as the requirement that Petroleum Properties can not be set for real Compounds.

It was decided to prefix a small number of Petroleum Properties with “petro” in order to avoid the confusion.The real Compound equivalent to each of the renamed Petroleum Property was introduced in the table that lists Petroleum bulk and Compound Properties.Also the properties referring to elemental contents were given a generic name.

It was deemed necessary to mention explicitely in the same table of Properties the references defining each of the Petroleum Properties.The search for references will be done off-line by KBC Advanced Technologies and by BR&E.

Next conference call is scheduled for April 25, 2017.
