Where ALSYS Technologies Add Value Across Oil & Gas
Oil and gas operators manage complex fluids, variable chemistries, and strict environmental requirements. The segments below outline the major operational areas where ALSYS technologies improve reliability, efficiency, and compliance.
Overview
Upstream operations manage produced water, injection water, surfactant-rich emulsions, and solids that disrupt separation performance and drive operating costs. Facilities must maintain stable flux, reduce downtime, and consistently meet reinjection or discharge specifications despite rapidly changing feed conditions.

Answers to Common Oil & Gas Treatment Challenges
Oil and gas operators face complex separation, water-quality, and emissions challenges that shift from upstream to downstream. The questions below highlight where membrane and catalyst technologies make the greatest impact and how ALSYS helps improve reliability, compliance, and overall system performance across the value chain.
Oil and gas facilities routinely encounter fluids containing emulsified oil, surfactants, corrosion inhibitors, fines, and dissolved organics that strain conventional equipment. These variations in feed chemistry can lead to inconsistent treatment performance, higher operating costs, and more frequent maintenance. Membranes provide a controlled separation environment that maintains predictable behavior even when the composition of produced or process water shifts during field or facility operations.
In many cases, the ability to tolerate aggressive cleaning and restore permeability is essential to sustaining long-term performance. Ceramic membranes remain stable under high-pH and oxidizing conditions, while polymeric membranes support polishing steps where finer particulates or emulsions remain. Together, these systems help operators meet discharge criteria, protect downstream equipment, and minimize process disruptions.
- Stable flux with oily or surfactant-rich feeds
- Compatibility with high-frequency chemical cleaning
- Improved solids removal compared to conventional media
- Consistent permeate quality for reinjection or reuse
Downstream environments introduce aggressive solvents, acids, polymeric intermediates, fines, and high-temperature process streams that place significant demands on filtration and emissions-control equipment. Variability in feed quality, batch transitions, and solvent composition can challenge consistency, while regulatory requirements impose strict limits on air emissions from furnaces, boilers, and heaters. Membrane and catalyst technologies must remain stable under these conditions to support reliable operation.
ALSYS provides ceramic and Hybsi membranes designed for chemical resistance, temperature resilience, and repeated exposure to oxidizing or caustic cleaning. Catalysts reduce NOx and VOC emissions while maintaining activity across temperature fluctuations and hydrocarbon-rich exhaust profiles. These technologies help operators protect assets, improve product quality, and maintain compliance without extensive equipment modification.
- Solvent-resistant membranes for purification and dehydration
- High-temperature cleaning compatibility
- Catalysts engineered for refinery heater exhaust
- Systems supporting long-term operational continuity
Produced water contains highly variable combinations of dispersed oil, dissolved organics, surfactants, corrosion inhibitors, solids, and reservoir-derived chemistry. These fluctuations can destabilize gravity separation and create fouling conditions for traditional filtration media. Ceramic membranes address these issues by providing a durable, chemically resistant surface that maintains flux and separation efficiency despite constant changes in water composition.
Their inorganic construction resists swelling, thermal shock, and chemical attack, allowing operators to use stronger cleaning protocols without damaging the membrane. This makes ceramic systems particularly effective for facilities with high fouling loads or frequent upsets, as permeate quality can be maintained through consistent cleaning practices and system controls.
- Resistant to surfactants and oil emulsions
- Capable of high-pH and oxidizing cleaning
- Stable performance across variable feed chemistry
- Suitable for continuous and batch operation
Combustion equipment is used throughout upstream, midstream, and downstream facilities, supporting heating, dehydration, compression, and numerous utility functions. These systems generate NOx and VOC emissions that operators must manage to meet regulatory requirements. The exhaust from this equipment often contains hydrocarbons and particulates that can interfere with catalyst performance if not accounted for in system design.
ALSYS Catalysts are engineered to maintain activity across temperature fluctuations, operational swings, and varying exhaust compositions. They integrate into existing equipment with minimal modification and support consistent emissions reduction over extended operating periods. For operators facing stricter air-quality obligations, catalytic systems offer a predictable and scalable pathway to compliance.
