A techno-economic perspective on benchmarking aging petrochemical assets

Evaluating Aging Petrochemical Assets Through Cash Cost of Production Analysis
As petrochemical assets age, the economics of operating these plants evolve. Shifts in feedstock markets, energy pricing, trade flows, and competitive supply additions can materially change a plant’s cost position over time. In an increasingly competitive global environment, understanding the true cash cost of production is essential for sustaining profitability and guiding strategic decisions.
Cash cost of production analysis provides a clear and practical lens to assess the short-term economic viability of an existing asset and to identify opportunities for margin improvement relative to competitors.
Cash cost represents the total out of pocket expenses required to operate a petrochemical plant and is often viewed as the minimum cost at which production remains economically viable. It reflects the costs that must be covered for continued operation, excluding non-cash or corporate level items.
Understanding Cash Cost of Production
Cash cost in a petrochemical asset typically includes the following components:

Certain costs are intentionally excluded from cash cost analysis to maintain focus on operational economics. These typically include general marketing expenses, research and development, depreciation, financing charges such as interest, working capital effects, and downstream logistics such as tariffs, freight, and handling costs to the final customer.
For asset owners, revisiting and reassessing cash costs over time is critical. Without periodic re-evaluation, plants risk losing competitiveness as relative cost positions shift across regions and technologies.

Benchmarking Aging Assets with FGE NexantECA’s Cash Cost Curves
In most petrochemical markets, pricing dynamics are driven by marginal production economics. In competitive industries, market prices tend to equilibrate around the cost of the marginal producer. As a result, understanding where an asset sits on the global cash cost curve is fundamental.
Benchmarking cash costs enables producers to address several strategic questions.
Pricing and profitability
Understanding how current and forecast market prices compare to a plant’s cash cost helps determine margin resilience across cycles.
Regional and technological competitiveness
Assets positioned at the lower end of the cost curve enjoy greater strategic flexibility, including higher operating rates, stronger margins, and resilience during downturns. Producers at the upper end of the cost curve must differentiate through product quality, integration, or operational excellence to remain viable.
Structural attractiveness of an industry
Industries with steep cost curves tend to be structurally attractive, characterized by limited competition, diversified technologies, advantaged feedstocks, and wide cost dispersion. In contrast, flat cost curves signal mature technologies, many competitors, and limited cost advantage, increasing margin pressure.
Impact of structural change
Cost curves allow assessment of how new capacity additions or emerging technologies may shift industry economics and pricing over time.

Developing Recommendations to Improve Cash Margins for Aging Assets
The Cash Cost Curve enables asset owners to identify where their plants underperform relative to peers. Common sources of cash margin gaps can be summarized as per diagram below:

Once gaps are clearly identified, structured and actionable improvement plans can be developed to close the margin gap relative to competitors.
Cost optimization strategies may include:
Feedstock sourcing optimization and contract restructuring
Manpower, utilities, and overhead cost optimization
Maintenance strategy and reliability improvement
Revenue enhancement strategies may include:
Process and yield optimization to maximize high value products
Minimizing low value byproducts while increasing monetization of higher priced streams
Re-optimization of product placement into higher margin markets
Reducing exposure to structurally low margin destinations
Operational performance improvement initiatives can further enhance margins through:
Increasing on stream factors and utilization rates
Implementing structured performance improvement programs
Re-optimizing turnaround timing and scope to reduce downtime
Asset margin analysis

Conclusion
Cash Cost of Production analysis and benchmarking are essential tools for evaluating the ongoing competitiveness of existing petrochemical assets. In an environment of shifting feedstock dynamics, evolving technologies, and intensifying competition, periodic reassessment of cash costs enables producers to protect margins, prioritize investments, and make informed strategic decisions.
