Five first-principles calculators that answer the five questions every evaporation, crystallization and decarbonization project must resolve — mass balance, energy strategy, project economics, crystallizer routing, and carbon reduction. Each runs in-browser, returns order-of-magnitude numbers, and takes less than two minutes.
TOOL VISUAL
Each tool targets a specific engineering question and uses a documented mass/energy balance or screening-grade emission factor. Start with the Evaporation Calculator for capacity, then move downstream to energy strategy, economics, crystallizer routing, and decarbonization — or jump directly to the question you need answered.
Solves the binary mass balance for water removal: given feed flow, initial concentration and target concentration, returns evaporation capacity (t/h water), concentrate flow (t/h), and concentration ratio. Independent of evaporator type — the upstream input to every downstream tool.
Compares annual purchased-energy cost of Mechanical Vapor Recompression (MVR, 15–25 kWh/t water) versus N-effect steam-driven evaporation (3/4/5 effects → 0.33/0.28/0.25 t steam/t water). Inputs: local electricity price, steam price, annual hours, effect count. The single largest OPEX decision in an evaporation project.
Computes simple payback period, 3-year cumulative net cash position, and annualized ROI (%) for a retrofit or new-build project. Inputs: total installed CAPEX (USD), annual energy savings, maintenance rate (% CAPEX), operating hours. Industry-typical 3-year payback hurdle is applied for go/no-go screening.
Recommends crystallization route (evaporative / cooling / vacuum cooling / reaction) and vessel configuration (Forced Circulation, DTB, OSLO fluidized-bed, or stirred-batch) from six process inputs: chemistry, solubility-temperature sensitivity, thermal sensitivity, target crystal size, throughput, and corrosivity. Weighted scoring against an installed-base matrix.
Estimates annual CO₂ reduction, carbon-credit value and tree-equivalent offset from retrofitting a steam-driven evaporator train to MVR or TVR. Steam emission factor 0.21 t CO₂/t steam (natural-gas boiler); grid factors selectable by region (China 0.58 t CO₂/MWh, EU 0.23, Nordic hydro 0.03). Scope 1 + Scope 2 screening only.
Each tool runs a documented engineering calculation and returns an order-of-magnitude estimate. Understanding what each number captures — and what it deliberately excludes — is the difference between a useful screening result and a misleading one.
Disclaimer. All tools on this page are provided for preliminary screening only. Results are derived from simplified first-principles mass/energy balances, documented specific-consumption bands (MVR 15–25 kWh/t, multi-effect 0.25–0.40 t steam/t depending on effect count), and regional grid emission factors. They do not account for boiling point rise, VLE of volatile species, fouling/scaling, viscosity, partial-load behavior, or feed-specific chemistry. They do not constitute a process guarantee, a fixed-price quotation, a code-compliant design, or a formal carbon inventory. Always validate with bench-scale testing and a qualified process engineer before making equipment or investment decisions.
Screening tools tell you the range. Our process engineers give you the answer — backed by feed-specific bench data, a code-compliant process design package, and guaranteed performance.
