Oil & Gas, Petrochemicals

Powering Performance across the Oil, Gas, and Petrochemicals Value Chain

The Oil, Gas & Petrochemicals industry continues to anchor global economic momentum, supplying essential energy and materials to support growing populations and expanding industrial demand. According to the International Energy Agency’s December 2025 Oil Market Report, global oil demand rose by 830,000 barrels per day in 2025, reflecting strengthening macroeconomic and trade conditions. The IEA projects a further increase of 860,000 barrels per day in 2026, with petrochemical feedstocks expected to drive more than 60% of total demand growth as the sector expands its role in the energy and materials value chain.

As the industry scales to meet this demand, particularly across both fuels and petrochemical feedstock production, the operational footprint is equally significant. McKinsey’s Global Upstream Operations Benchmark reports that upstream production spans more than 23 million barrels of oil equivalent per day across more than 600 assets worldwide, generating over 55 million tons of CO₂ emissions annually. These figures highlight the immense responsibility and opportunity for operators to improve efficiency, reliability, and environmental performance across the value chain, from traditional oil and gas operations to the expanding petrochemical sector.

Market Outlook & Challenges

Operators across upstream, midstream and downstream petrochemical segments are navigating a complex set of pressures as they balance production, efficiency, and compliance requirements. Tightening emissions and product quality standards, variable and circular feedstocks, and the need to decarbonize operations make early, well-founded decision critical.

How can operators keep product flowing smoothly while protecting asset integrity?

Challenge 
Maintaining flow under variable temperatures and compositions while avoiding deposition, gel-related blockages, and unplanned downtime. 

Impact
Pressure drop, pigging frequency, equipment stress, reduced injection effectiveness, and lost barrels. 

Solution principles
Outcome‑led cold‑flow and deposition‑control programs that keep products moving and protect asset integrity (e.g., dewaxing aids, tailored polymers), in addition to the use of persulfates in enhanced oil recovery to initiate polymer gel formation and later oxidatively break those gels to restore flow pathways.

How can operators treat produced water effectively without creating downstream complications?

Challenge
Produced‑water handling and microbial control without creating chlorinated by‑products, while managing iron and other oxidizable contaminants.

Impact
Permit risk, safety concerns, chemistry incompatibilities, treatment inefficiency, and buildup of oxidizable species that complicate downstream processing. 

Solution principles
Rapid, oxidizing biocides that work at low temperatures and decompose into benign co‑products, combined with hydrogen peroxide as an additional oxidation chemistry for produced‑water environments, where it acts as a versatile oxidizer and becomes a more powerful oxidant when catalyzed with iron.

Hydrogen pipeline construction from Legden through the Marl Chemical Park to the refinery site in Gelsenkirchen.
50 km of pipeline was laid. The project has three construction phases.
1. A 40 km natural gas pipeline was converted to hydrogen.
2. A new 3 km section through the chemical park was built. 
3. A new 10 km hydrogen pipeline to the refinery in Gelsenkirchen-Scholven was completed.

The pipeline is part of the GET H2 Nukleus project.

How can producers maintain catalyst health and product quality as feedstocks become more variable?

Challenge
Shifts from conventional naphtha/LPG to variable or recycled streams raise impurity loads, drive catalyst deactivation/fouling, and complicate cracking and separations. 

Impact
Shorter run lengths, higher energy intensity, off‑grade polymers, VOC exposure, and turnaround pressure. 

Solution principles
Up‑front purification and contaminant control, catalyst protection/guard beds, and stabilizers that support consistent polymer‑grade quality.

Our Applications

Sustainability & Compliance

Compliance is often business‑critical. Our materials are engineered not just for performance, but to help operators navigate permitting, emissions standards, and stewardship requirements — including methane/VOC controls, sulfur limits, and produced‑water management. 

  • Oxidizing biocides: rapid efficacy at low temperatures; avoid chlorinated by‑products; decompose into benign co‑products. 
  • Membrane gas separations: can reduce energy intensity versus certain thermal alternatives; compact, modular systems. 
  • Durable materials (e.g., PA12, PEEK): corrosion resistance that can lower replacement frequency and risk. 
  • Petrochemicals focus: VOC management, trace removal for polymer quality, and strategies for variable/circular feedstocks to stabilize operation and emissions.

Frequently Asked Questions

Flow assurance refers to the strategies and chemistries used to keep hydrocarbons moving from reservoir to refinery by managing wax, asphaltenes, hydrates, and scale. Effective programs reduce pressure drop, prevent blockages, minimize pigging frequency, and protect asset integrity — ultimately improving throughput and operating margins.

Oxidizing biocides like peracetic acid provide rapid antimicrobial action, work at low temperatures, and avoid chlorinated by-products. They decompose into benign co-products, supporting environmental goals and compatibility with other chemistries used in fracturing or produced-water treatment.

Hollow-fiber membranes are well suited for natural gas upgrading, nitrogen generation, and biogas applications where compact systems, modularity, and selective separations are beneficial. Material robustness against pressure and temperature enables stable performance and simplified operation for many plants.

High-performance polymers such as PA12 and PEEK are used for components that must endure pressure, temperature, and aggressive media. Their corrosion resistance and mechanical stability support longer service life versus some conventional materials, on- and offshore.

Purification materials used to remove water, sulfur species, mercury, and other contaminants help stabilize downstream refining and petrochemical units by protecting sensitive equipment and improving process reliability. Regeneration and rejuvenation services can extend the life of catalysts, improving cost efficiency while reducing the environmental impact associated with full catalyst replacement. In addition, desulfurization and conversion catalysts play a key role in meeting sulfur‑content regulations in transportation fuels and in upgrading petrochemical intermediates into higher‑value products — supporting cleaner, more efficient downstream operations. 

Catalysts can be affected by a range of impurities such as sulfur species, nitrogen compounds, metals, water, oxygenates and halogens, all of which can reduce activity, shorten run lengths or disrupt cracking and polymerization performance.

Effective purification helps remove trace contaminants that interfere with catalyst systems or cause color, stability or processing issues in downstream polymers, supporting more consistent, high‑quality product grades.

As feedstocks become more diverse — especially with recycled or circular streams — operators rely on upfront purification, contaminant control and stabilization strategies to protect catalysts, maintain throughput and ensure product consistency.
