Aromatics Extraction

thyssenkrupp Uhde'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 solutions and technologies for aromatics production, some in cooperation with valuable partners:

  • Divided wall fractionation

  • Coke oven light oil hydrorefining

  • Selective hydrogenation of pyrolysis gasoline

  • Toluene disproportionation

  • Dealkylation of aromatics

  • Olefin removal units (whitening or clay treating, hydrorefining).

Through an alliance with thyssenkrupp Uhde (Paramax Alliance), Axens also offers the Morphylane® process for licensing within grassroots aromatics complexes that produce para-xylenes and other petrochemical products within the product value chain.

Morphylane® extractive distillation

The purpose of the Morphylane® extractive distillation (ED) process is to produce high-purity aromatics products. A special characteristic of the Morphylane® ED process is its use of the solvent N-formylmorpholine (NFM), which combines optimum selectivity and solvent efficiency.

Use of this solvent offers the following advantages:

  • High permanent thermal and chemical stability

  • No corrosive effect

  • No toxicity / non-hazardous

  • No need to add water

  • Single-component solvent

  • Low basic nitrogen content

  • Small solvent inventory, low price.

thyssenkrupp Uhde's Morphylane® process for aromatics extraction boasts:

  • maximum product purity

  • high yields

  • extremely low energy consumption.

Process flow sheets for aromatics extraction

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

In thyssenkrupp Uhde’s proprietary Morphylane® ED process, a single-compound solvent, N-Formylmorpholine (NFM), alters the vapor pressure of the components to be separated. The vapor pressure of the aromatics is lowered more than that of the less soluble non-aromatics, thus allowing the two to be separated.
