Abstract: The present invention relates to a method performed by a system (110) operable to configure a chemical separation system (120), the method comprising: receiving system hardware configuration data, wherein the system hardware configuration data is at least indicative of fluid manipulation modules (121_1-12N_M) of the chemical separation system (120), desired functionality of the fluid manipulation modules, and a fluid network (210) comprising fluid couplers configured to fluidly couple the fluid manipulation modules (121_1-12N_M), identifying a first set of function blocks to provide the indicated fluid manipulation modules with the desired functionality, generating a second set of function blocks by purging a third set of function blocks from the first set of function blocks to eliminate dead code using the configuration data, sending the second set of function blocks to the system (120).
