Process Integration & Synthesis using Chemical Engineering Standards
An expanding public database
Our public flowsheet database is constantly growing in size,
and actively curated for quality.

Built on the Standard Flowsheet Format
SFF is an open, non-proprietary JSON standard that represents process flowsheets as directed graphs: unit operations are nodes, process streams are edges, and rich data attaches to both.
PISCES uses SFF to exchange process flowsheets across supported tools. Structured data makes connections, properties, and source information easier to inspect and reuse.
Partial SFF example. Required metadata and other sections are omitted for readability.
