Permylene Performance

Permylene membrane systems have several highly desirable olefin-paraffin separation performance attributes:

  • Typical olefin product purities are > 99.5% for a wide variety of olefin-paraffin feed compositions and high recovery levels are achieved
  • Commercially attractive permeation rates are achievable and olefin recovery often exceeds 90%
  • Stable performance has been demonstrated over tests covering thousands of hours

Process Integration

The modular design of the Permylene membrane system allows for easy, incremental expansion if needed and can be easily integrated with other process systems in the plant.  The Permylene system can also be hybridized with existing distillation systems. 

Design and Operation

Designed for continuous operation, Permylene's processing capacities can meet any industrial olefins separation requirements due to its modular equipment design.  The fundamental system building block, the Permylene membrane element, can process between 30 and 100 kilograms per hour (depending on the application).  System size and performance is then tailored using a number of these elements in series or in parallel as required.

Technology Charactaristics

Permylene demonstrates outstanding selectivity for separating olefins from their mixtures with paraffins or other gases.

  • Permylene is primarily suitable for C₂, C₃ and C₄ olefin-paraffin separation applications
  • Permylene operates in the vapor phase, with gaseous feed and product streams involving no phase change and requiring no reflux
  • Constructed of proprietary polymeric materials, the operating temperature range for the Permylene membrane system is between 10℃ and 70℃, making a wide range of practical operating pressures available for various olefin / paraffin separations

Commercial Systems

Imtex has taken great care to maximize performance, stability, efficiency, ergonomics and ease of operations and maintenance in its system designs. The modular nature of the Permylene membrane technology enables the system design to be both flexible and scalable. Permylene joins the trend of membrane technologies being employed more extensively in industrial gas separations such as carbon dioxide removal from natural gas, air separation, hydrogen removal from syngas, etc.

Key characteristics of the Permylene system:

  • Ease of operations: ergonomically designed cassette layout allows for ease of maintenance
  • Design allows for installed spare/standby cassettes and ease of incremental capacity expansions
  • Easy to replace, standard design membrane elements
  • Designs compliant with all safety, pressure rating, electrical and other industrial standards for hydrocarbon processing applications

Imtex has been working for a number of years to make Permylene membrane systems ready for commercial applications. If you are interested in a demonstration at your location.
