Chemical value chains

The chemical industry is presented in an overview with chemical value chain structures, industry specifics, market structures and trends before focusing on commodities. 

The chemical value chain shown in fig. 26 results into a product tree over multiple steps starting from the oil refinery and a steam-cracker, chemical products are processed over multiple steps with increasing variety and complexity by adding further substances or additives. The chemical product tree is often reflected in the production structure of chemical produc-... 

This classification correlates with the chemical value chain and the product tree. Products produced in early stages of the product value chain are rather commodity-type products, while products produced in the very late stage of the value chain are rather specialty-type products. Commodity and specialty classification is often not straight-forward and can depend on a set of characteristics as shown in table 6 ... 

Specialty chemicals value chains often contain a large number of different products. Considering the data requirements discussed above, it is critical to sufficiently aggregate the product portfolio. In a first step a classical ABC analysis was performed to identify the most important products. The pilot value chain analyzed consisted of a total of 350 different products. As can be seen in Figure 38, the top 10% of products already represent more than 60% of the total production volume. The share of total production volume that should be modeled explicitly depends primarily on the variability of raw material and - to a lesser extent - processing requirements across the product portfolio. In the case study 20% of products representing 80% of demand were modeled explicitly.
