Global ethylene, propylene and butadiene markets are shifting. NGLStrategy’s study provides a fresh look at the future of seaborne petrochemical gas trade and the impact on shipping.

NGLStrategy’s annual study investigates changes to the ethylene, propylene and butadiene seaborne trade market. The impact of changes in such markets on petchem gas shipping is investigated including requirements for larger vessel specifications.
For ethylene, as the US expands its steam cracking industry based on cheap ethylene from ethane, there is the potential for a big expansion of ethylene exports. At the same time, investments in new steam crackers and derivative plants in China and Europe may change global ethylene trade patterns.
The propylene industry is going through a rapid change with the influx of new capacity additions. The influence of such additions on propylene trade is summarised in the report.
The study also looks at the butadiene market and changes in dynamics between East and West.
