In addition to biopolymers which are accessible through fermentation such as PHB and enzymes like thermostable glucananase and xylanase for animal feed, BASF is also looking at the fermentation of succinic acid. (Pictures: BASF) (Archiv: Vogel Business Media)
Seeking an Intelligent Mix

Where Will the Chemical Industry Get Its Raw Materials in the Future?

Whether coal, gas or even biomass will replace petroleum as the chemical raw material of the future is not yet clear. However, one thing is certain. Alternatives will be needed in the long term despite that fact the even pessimists predict that oil will be available for the next forty years. High prices, increasing consumption in Asia and the chaotic political situation in the oil producing countries add an element of urgency to the discussion on diversification of the raw material base. The industry is looking for an intelligent mix and an evolutionary approach to the supply of raw materials.

The importance of mechanical com-
pression of vapors is increasing, due in part to the declining susceptibility of the compressors to faults thanks to improvements in materials and sophisticated monitoring and safety installations.  Pictures: Gea Wiegand (Archiv: Vogel Business Media)

Mechanical Compression of Vapors Increases Efficiency

Energy costs have now become a long-term issue in the chemicals sector and are becoming an important efficiency factor. Process versions which only a few years ago laid abandoned and disregarded in the drawer due to their high investment costs are benefiting from this sea change. This also includes mechanical compression of vapors in evaporators which remained in the long grass for a long time and is now enjoying a renaissance.
