Engineering Basis

Methodology

Converts flow and active-ingredient dose to active demand, then uses entered active mass fraction and product density for product feed, storage, and pump-rate screening. Product strength and density are user inputs; they are not inferred by the model.

Active demand = flow × user-entered active dose × 0.001. Commercial product mass = active demand / user-entered active mass fraction, where fraction means active ingredient mass per commercial product mass.

Product solution volume = commercial product mass / user-entered product density (kg/L). Normal feed = daily solution volume / 24 h.

Working storage = daily product volume × storage days. Gross storage basis = working storage / usable storage fraction.

Minimum and maximum feed cases use the entered design doses. Required turndown = maximum / minimum feed when minimum feed is positive.

Pump-rate screening assumes entered duty pumps share the required feed equally. Pump staging/on-off control is not modeled.

Scope / Limitations

Each chemical retains a separate feed and storage system. Optional dose range, usable storage fraction, density, and pump capability are evaluated from entered inputs.
Each chemical has a separate storage and feed system. No cross-chemical arithmetic total is presented as a shared tank, feed, or pump sizing basis.
Does not select a manufacturer, size piping, determine material compatibility, predict product degradation, or replace tank-code design.
Pump capability is compared only with user-entered turndown data; this is a screening comparison and not a pump selection or performance guarantee.
Product active mass fraction and density are user-entered; solution concentration and dilution-water demand are not calculated. Storage volume is per chemical system; tank count is not calculated. No US-unit conversion path is implemented; inputs and outputs use SI units.

Upstream Context

Whole-plant configuration and design cases Use the declared process arrangement, flow cases, and operating assumptions as context; this tool supports plant-wide design and is not a sequential stage.
