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 to design optimized processes and estimate 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 cost of CH4. When the membrane surface area of one stage is varied, the other surface are held constant at the values of corresponding to Case C in Table DD.

Example of completed project #2

Goals

Separate a mixture of O2/N2

  • Minimize the cost: CAPEX/ OPEX
  • Maximize purity, 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
