Design of Experiments

Chemical processes involve complex multi-variable interactions where DOE delivers 15–30% yield improvements. Our engineers systematically optimise reaction conditions, catalyst performance, and distillation parameters through statistically rigorous experimental design.

[INDUSTRY_CHALLENGES]

DOE Challenges
in Chemical Processing

Reaction complexity, catalyst interactions, and safety constraints drive chemical processing DOE needs.

Reaction Yield Maximisation

Temperature, pressure, residence time, and catalyst loading all influence reaction yield and selectivity. DOE identifies the optimal combination while respecting safety and equipment constraints.

Catalyst Performance Tuning

Catalyst activity, selectivity, and lifecycle depend on operating conditions. DOE determines the factor settings that maximise catalyst utilisation and minimise deactivation rates.

Distillation Column Factors

Reflux ratio, feed location, tray design, and operating pressure interact to determine separation efficiency. DOE optimises column performance while minimising energy consumption.

Scale-Up Validation

Laboratory-optimised conditions must be validated at pilot and production scale. DOE identifies which factors are scale-sensitive and establishes robust operating windows for scale-up.

[DOE_PROCESS]

Our 8-Step
DOE Framework

A systematic 8-step DOE methodology for chemical process optimisation and yield improvement.

01

Planning

Define clear objectives, success criteria, and measurable KPIs that align the experiment with your broader engineering and business goals.

Identify all relevant factors and their operational levels, establish measurement system reliability through Gauge R&R studies, and define statistical control boundaries. A robust plan ensures resources are allocated efficiently and that every test run produces actionable data.

02

Screening

Run targeted preliminary experiments to separate the critical few factors from the trivial many, drastically reducing experimental scope.

Leverage Fractional Factorial, Plackett-Burman, or Definitive Screening Designs to evaluate dozens of potential variables in a fraction of the runs a full factorial would require. The deliverable is a ranked Pareto chart of factor significance, enabling your team to focus on the variables that truly drive performance.

03

Modelling

Construct a rigorous mathematical model that quantifies how significant factors and their interactions drive your response variable.

Apply Full Factorial or Response Surface designs to capture main effects, two-way interactions, and curvature. The resulting model is validated with ANOVA, residual diagnostics, and R-squared metrics to ensure it reliably predicts system behaviour across the design space.

04

Optimisation

Fine-tune factor settings using response surface methodology to pinpoint the operating conditions that maximise yield, quality, or efficiency.

Deploy Central Composite or Box-Behnken Designs to map the response surface and locate global optima, even in the presence of complex factor interactions. Multi-objective optimisation techniques such as desirability functions are applied when balancing competing performance targets.

05

Verification

Execute confirmation runs under the predicted optimal conditions to validate that the model accurately reflects real-world process behaviour.

Compare observed responses against model predictions using confidence and prediction intervals to assess agreement. If deviations exceed acceptable thresholds, the model and optimisation parameters are iteratively refined until robust, repeatable performance is confirmed.

06

Execution

Carry out each experimental run according to the randomised design matrix, maintaining strict control over environmental conditions and procedural consistency.

All relevant process parameters, environmental readings, and response measurements are recorded in structured data logs with full traceability. Randomisation and blocking strategies are enforced to guard against systematic bias, ensuring the collected dataset is statistically sound.

07

Analysis

Apply statistical analysis — including ANOVA, effect plots, and contour maps — to extract meaningful patterns, interactions, and correlations from the experimental data.

Beyond classical statistics, advanced predictive models are built using neural networks (SANN), machine learning algorithms, and AI-driven pattern recognition. These complementary techniques uncover non-linear relationships that traditional regression may miss, delivering deeper process understanding.

08

Utilisation

Translate experimental insights into concrete process improvements, updated specifications, and operational best practices that drive measurable business value.

A comprehensive report documenting the experimental design, statistical findings, and recommended operating windows is delivered to all stakeholders. Knowledge is embedded into SOPs, control plans, and continuous improvement frameworks to ensure long-term retention and replication across projects.
