Example of completed project #1

Goals

Separate a mixture of gases

  • Select the right materials
  • Sizing and modeling membrane stages

Definition

How to choose the best membrane technologies?

Compare different membrane types and configuration.

Specify the cost function with viable economic parameters.
  • Cost model used in the optimization

  • Economic parameters used in the cost model

Process design and optimization

We have methods and databases for designing optimized processes and estimating costs.

  • Multistage membrane separation process for the recovery of CH4 and CO2 enriched streams

  • Effect of membrane surface area of each membrane stage on the specific separation costs of CH4.

Example of completed project #2

Goals

Separate a mixture of O2/N2

  • Minimize the cost: CAPEX/ OPEX
  • Maximize purity and recovery rate

Design of a membrane architecture

What is the best architecture?

Single-stage

Multi-stage
And what about a more complex architecture?

Optimization multi-goals

We have developed digital tools based on AI to best respond to these issues.

  • Experimental setup for “Time Lag” method: measurement of permeability, diffusion, solubility parameters
  • Fiber counting by image analysis
  • Scanning electron microscopy (SEM)
  • Data acquisition on experimental pilot units
  • New materials or commercial membranes
