Abstract
A fundamental solution to the problem of the structure of a comprehensive
relational data base for chemical process data is proposed. The proposed
data base structure can hold data about the physical attributes of chemical
processes and about their reactants, products, and catalysts. By means of a
relation that essentially contains both process composition and process
stream (flow) recursive relationships, the data base also holds data about
the breakdown of any process into its subprocesses, their subprocesses,
and so on, to any desired breakdown level, and about how these subprocesses
connect to form flow networks at each level of decomposition. The relational
data base language SQL can easily be used with the data base, which makes it
suitable for field use in remote locations. Where molecular substructure
data is also needed, then the chemical process data base can be used with a
comprehensive relational molecular structure data base.
