Unit Optimization Solutions
Sulfuric acid alkylation unit design and performance review
An on-site review of plant design, operation, and performance, producing an in-depth report with specific prioritized recommendations for improved plant safety, performance, and operating procedures.
Effluent treating system design and performance review
An on-site study focused on effluent treating system equipment, procedures, and performance.
Acid blowdown and neutralization system evaluation
- Sulfuric acid alkylation unit design and performance review
Operator training simulators
A dynamic simulator programmed with real-life emergency scenarios for improved operations response and procedures training. Emergency scenarios include acid runaway, power failure, instrument failure, improper feed lineup, and more.
Operator training courses and programs
A comprehensive training course tailored to your STRATCO® alkylation unit configuration. The contents are flexible and can be customized to your special interests, providing constructive training for both new and experienced engineers and operations personnel.
Process-Critical Equipment Solutions
Coalescing media and vessels
Designed and manufactured to separate immiscible liquids in alkylation unit feed coalescers, acid settlers, effluent treating and depropanizer feed treating wash drums, and other separators.
Designed for proper contacting of hydrocarbon and acid or aqueous streams in alkylation unit effluent treating and depropanizer feed treating wash applications.
Reaction Zone Monitoring System (RZMS)
A complete package, with panel-mounted ratio glass, acid sampling system, and acid analyzer for on-line acid strength and acid-to-hydrocarbon ratio in STRATCO® Contactor™ reactors. DuPont-approved acid correlations are downloaded into transmitters.
- Acid Transfer Monitoring System (ATMS)
Acid sampling systems
Designed for safe, closed-loop acid sampling in the field. Includes panel-mounted acid sampling procedures.
Test run and existing alkylation unit simulation
On-site reviews that include sample and data collection. Our refinery services experts use this information to set up a simulation (to match test run conditions), test equipment limitations, and identify debottlenecking opportunities. An excellent precursor to an expansion study.
- Unit revamp and expansion studies & process designs
Together, Shaw and DuPont provide innovative solutions for the sulfuric acid alkylation industry through the combination of STRATCO® alkylation technology, detailed engineering, procurement, construction, training, commissioning, startup, maintenance, and reliability services.
