Aromatics Extraction

Aromatics Extraction

thyssenkrupp Industrial Solutions's Morphylane process for aromatics extraction is one of the world's leading technologies for the production of high-purity aromatics. The company also offers a wide range of process design and technologies for aromatics production, partly supported by cooperation with valuable partners:

  • divided wall column fractionation

  • coke oven light oil hydrorefining

  • pyrolysis gasoline selective hydrogenation

  • toluene disproportionation

  • aromatics dealkylation

  • olefin removal units (Whitening, clay treating, hydrorefining)

Through an alliance with thyssenkrupp Industrial Solutions, Axens also offers the Morphylane® process for license within grassroots aromatics complexes producing para-Xylenes (Paramax Alliance) and other petrochemical products within the product value chain.

Morphylane® Extractive Distillation

The task of the Morphylane® extractive distillation process is to produce high purity aromatics products. A special characteristic of the Morphylane® extractive distillation process is the use of the solvent N-formylmorpholine (NFM) combining optimum selectivity and solvent efficiency.

The applied solvent NFM provides the following advantages:

  • High permanent thermal and chemical stability

  • No corrosive effect

  • No toxicity / non hazardous

  • No water addition

  • Single component solvent

  • Low basic nitrogen content

  • Small solvent inventory, low price

thyssenkrupp Industrial Solutions Morphylane® process for aromatics extraction is characterized by:

  • maximum product purity

  • high yields

  • extremely low energy consumption

Process Flow Sheets of Aromatics Extraction

The Morphylane® Process is the technology for recovery high-purity aromatics from reformate, pyrolysis gasoline, coke oven light oil and synthetic feedstock sources using extractive distillation (ED).

 

In thyssenkrupp’s proprietary extractive distillation Morphylane® process, a single-compound solvent, N-Formylmorpholine (NFM), alters the vapor pressure of the components being separated. The vapor pressure of the aromatics is lowered more than that of the less soluble non-aromatics allowing for the separation of the aromatics from the non-aromatics.
