BASF PETRONAS Chemicals Integrated Aroma Ingredients Complex, Gebeng, Kuantan, Malaysia


L-menthol

Malaysian joint-venture (JV) BASF PETRONAS Chemicals started the construction of an integrated aroma ingredients complex at its Gebeng Industrial Park near Kuantan in April 2014. The new facility will produce citral, citronellol and L-menthol, which are used in home and personal care products and fragrances, as well as in the food and pharmaceutical industries.



Carbon Holding's proposed Tahrir Petrochemical Complex is to be located within the Ain Sokhna industrial zone.


The MYR1.5bn (approximately $500m) project, which is funded 60% by BASF and the remaining by Petronas Chemicals Group (PCG), is expected to generate approximately 120 new jobs. The project is designed primarily to meet the increasing demand for citral-based products in the Asia Pacific region.

The complex is being constructed in phases, with production from the first plant scheduled for 2016. Integrating the existing infrastructure at Gebeng is expected to benefit the project.

Flour was awarded the engineering, procurement and construction management (EPCM) contract for the project. In September 2013, the company completed front-end engineering and design (FEED) for the project.

Applications of citral, citronellol and L-menthol

Citral is an aroma chemical identical to the natural ingredient found in oils of certain plants, such as lemon grass and litsea cubeba. It provides a lemon, citrus and fruity odour and taste. It is used in the imitation of flavours, the production of vitamins A and E, and as a precursor for aroma ingredients.

L-menthol is used in the food industry and oral care products for its fresh taste. Its cooling effect makes it useful for the body care industry and pharmaceutical applications, such as ointments and inhalers. Citronellol, which produce a rose-like fragrance, is used in floral compounds and insect repellents.

Feedstock and production of aroma ingredients

The complex will use manufacturing processes based solely on petrochemical feedstock. Citral will be produced by the synthesis of isobutene and formaldehyde molecules under high pressure, while L-menthol will be produced using citral as feedstock in a process involving asymmetric hydrogenation with a catalyst, including two further synthesis steps. The products will undergo special distillation processes before delivery.
