Caspeo intervenes at the different stages of a process design:
    - preliminary design,
    - advanced design,
    - engineering.

Caspeo integrates the team of the design project performing studies for sampling, material balance, process modeling and numerical simulation.

To carry out these tasks, Caspeo uses ECHANT, BILCO and USIM PAC software.

Preliminary design

The orientation laboratory trials are conducted on raw material samples. Based on its expertise in sampling, Caspeo helps in the definition and constitution of these samples and determines their level of representativeness.

From the results of the orientation laboratory trials, Caspeo uses modeling and numerical simulation techniques to deliver elements for a first evaluation of the feasibility of the industrial plant.

This evaluation concerns the global plant performances, the product quality, the environmental impact, the capital and operating costs. It allows comparison between various options and selection of the most promising ones for an advanced design.

Advanced design

The advanced design tries to obtain a maximum of data from laboratory and pilot plant scale trials with the objective of refining the plant feasibility and calculating the equipment sizes.

Here also, the laboratory and pilot plant scale trials are conducted on raw material samples. Data are generally obtained by analysis of product and sub-product samples. Caspeo helps in the definition and constitution of the different kinds of samples and determines their level of representativeness.

Caspeo validates the experimental data coming from the different trials by the aid of data reconciliation by statistically coherent material balance.

The more accurate data and the modeling and numerical simulation techniques allow Caspeo to better evaluate the equipment sizes and to compare different options through various criteria.

Engineering stage

During the engineering stage, Caspeo uses numerical simulation to evaluate the impact of the technological choices on the plant performances.

The experience of Caspeo in sampling and material balance is then useful in the choice of sampling locations and techniques along the process. The objective is then to have an optimal follow-up of the future plant.
