Our expertise and laboratory to develop your evaporation processes.

In brief

Evaporation is a separation technique generally used to preconcentrate a mixture or replace distillation when the difference in boiling temperature of the constituents is high (e.g., in devolatilization and tar removal).

Processium has the tools and know-how to develop evaporation processes from end to end.

Services

• Acquisition and modeling of thermodynamic properties (vapor pressure, phase equilibria, enthalpy and more);
• Evaporation process simulation, pairing with other unit operations, energy integration, etc.;
• Experimental validation at laboratory scale;
• Choice of technologies, sizing and economic estimates;
• Support in working with an equipment supplier.

Digital

A wide range of third-party and in-house tools enable our engineers to model and simulate evaporation processes. For example, Processium has the following tools:

• Aspen Plus;
• Aspen Exchanger Design and Rating;
• ProSim;
• and more.

Thermodynamics

Processium has tools to acquire precise thermodynamics data: phase equilibria, vapor pressure, and more. We have the following tools:

• Ebulliometer;
• Units to measure static or dynamic liquid-vapor equilibria, equipped with online samplers.

Measurements can be performed over wide temperature and pressure ranges, from -20°C to 280°C, and from 0.1 mbar to 100 bars.

Evaporators

Experimental validation is carried out at Processium’s process laboratory using the following units:

• A batch evaporator, suited to manual handling of products to understand their rheological properties;
• A wiped film evaporator (operating continuously), suited to products prone to clogging, as well as to heat-sensitive or very heavy products;
• A short-path evaporator (operating continuously), suited to heat-sensitive or very heavy products.

Our evaporators can be operated over wide temperature and pressure ranges, from 50°C to 250 °C, and from 10-3 mbar to 1 bar.
