A visual process-simulation environment for chemical engineers, built around drag-and-drop flowsheets and DWSIM and IDAES engines.

Landing page captured for the 2026-08-26 issue.

Field notes

Streamlines presents process modeling as a visual canvas: users place and connect unit-operation blocks, then run the resulting flowsheet through DWSIM or IDAES. The page lists support for Excel, CSV, and text imports, along with custom mixtures, crude-oil assays, and generated pseudocomponents. It also names CAPE-OPEN compatibility and native operation on Windows, macOS, and Linux. The homepage claims a database of more than 1,500 compounds, although its visible compound, block, and example counters currently show zero.
