Technical articles, interactive engineering tools, process flow diagrams, technology overviews and project references — organized for project engineers evaluating evaporation and crystallization systems. Content is written for engineering evaluation, not for marketing purposes.
In-depth technical writing on evaporation, crystallization and process design. The latest published articles are below — the full catalog lives on the blog.

Core evaporation and crystallization technologies, each with a dedicated page — working principle, applicable feed and duty, and design characteristics.
All technology pages: Technologies →
Annotated process flow diagrams for reference configurations. Diagrams are schematic and project-agnostic — actual PFDs are developed per project during detailed engineering.
Single-train ZLD on high-TDS brine where electric utility is cheaper than steam
Steam-driven concentration + crystallization for fertilizer-grade ammonium sulfate
Compressor integration on Effect 1 of a 3- or 4-effect train approaching boiler limits
Differential-solubility staging for binary NaCl / Na₂SO₄ salt systems
Secondary crystallization with controlled purge for impurity management
Low-temperature crystallization for thermally sensitive organics (amino acids, citric acid)
Two-stage concentration: clean-liquor finishing followed by fouling-prone final-stage
Wet-oxidation pre-treatment + ZLD for pesticide / pharmaceutical effluents
Process flow diagrams on this page are reference configurations for educational purposes. They are not project-specific engineering deliverables and should not be used for construction, permit application or process safety review without re-validation under a formal engineering services agreement.
Free browser-based calculators for preliminary project evaluation — each tool runs on this site, no download or sign-up. Outputs are indicative screening values, to be validated during detailed engineering.
Binary mass-balance evaporation: three inputs return water removal rate, concentrate flow and concentration ratio instantly. Screening only.
Compare annual purchased-energy cost of MVR vs 3/4/5-effect steam evaporation using your local steam and electricity prices.
Estimate CO₂ reduction and carbon-credit value from a steam-to-MVR retrofit — Scope 1+2 screening with regional grid factors.
Six process inputs return a recommended crystallization route and vessel configuration: FC, DTB, OSLO or stirred-batch.
Simple payback, 3-year net savings and annualized ROI from CAPEX, energy savings, maintenance rate and operating hours.
Authorized, anonymized case studies with documented feed, duty and process route — ZLD, crystallization, mother liquor recovery and MVR retrofit projects.
Tell us about your project. We can share project-specific references, PFDs and selection rationale under NDA where the public library is insufficient.
Send your feed characterization (TDS, COD, main salts, viscosity), throughput and product targets — we respond with a preliminary process route within two business days.
