Our Holistic offering
The refining industry uses our technologies to contend with difficult circumstances regarding environmental compliance, safety, energy efficiency, and reliability. From new builds to revamps, our advanced proprietary equipment allows for maximum quality and profitability while minimizing environmental impact.
our innovative solutions
As tail pipe emissions standards tighten and vehicle fuel efficiency standards rise, alkylate plays a critical role in gasoline pool blending. Of the many components comprising the gasoline pool, alkylate provides the most reliable source of low sulfur, low Rvp, high octane blending characteristics.
STRATCO® alkylation technology is the premier sulfuric acid alkylation process on the market today. For a comprehensive solution, the STRATCO® technology is available with the MECS® sulfuric acid regeneration technology.Learn more
Ultra-Low Sulfur Diesel
When you need a cost-effective solution for hydrotreating and mild hydrocracking applications, IsoTherming® hydroprocessing technology provides a commercially-proven alternative to conventional trickle bed technology. Using a liquid-full reactor system, IsoTherming® technology can process a wide range of feedstocks (including kerosene, straight run diesel, DAO, 100% LCO, 100% VGO, …) while maintaining robust catalyst life and significantly reducing operating costs.
Air Pollution Control
Air Pollution control is an issue affecting refiners worldwide. Reliable SOx, NOx and particulate removal technologies are key to successful refinery operations. The BELCO® wet scrubber is the industry standard on FCC flue gas stacks ensuring compliance between turnaround cycles of over 5 years. MECS® DynaWave® reverse jet scrubbers have proven benefits in sulfur recovery unit (SRU) tail gas scrubbing applications and removal of H2S from sour gas.
Sulfuric Acid Regeneration
As a compliment to the STRATCO® alkylation technology or as a stand-alone sour off-gas recovery option, the MECS® sulfuric acid technology is best-in-class for dry gas processing. The MECS® sulfuric acid regeneration (SAR) technology can produce the high purity sulfuric acid (99.2%) required in the alkylation process ensuring the highest quality alkylate production. The MECS® sulfuric acid production technology can also be used to capture sour refinery off-gasses for conversion into sulfuric acid, a valuable and saleable productdownload brochure
