Product Name
|
Advanced Fixed Bed Reactor for Optimal Naphtha Conversion
|
|
Core Function
|
Specifically engineered to maximize naphtha conversion efficiency through catalytic reactions, such as reforming and hydrotreating. The fixed - bed structure ensures stable contact between naphtha feedstock and catalysts, optimizing product quality and yield in petrochemical refining processes.
|
|
Reactor Type
|
Fixed - bed configuration with a tubular or cylindrical design, facilitating plug - flow behavior to minimize backmixing and enhance reaction uniformity. Suitable for both continuous and semi - continuous operation in large - scale naphtha processing plants.
|
|
Capacity
|
Customizable based on industrial requirements, typically ranging from 500 to 10,000 barrels per day (bpd) of naphtha feedstock processing, catering to various refinery capacities and production demands.
|
|
Material
|
- Reactor body: Constructed from high - grade alloy steels (e.g., Cr - Mo steel) or corrosion - resistant stainless steels (such as 316L) to withstand high temperatures (up to 600°C) and harsh reaction conditions, including hydrogen - rich environments.- Inner lining options available for enhanced chemical compatibility.
|
|
Catalyst System
|
- Designed to accommodate a wide range of naphtha - processing catalysts (e.g., platinum - based reforming catalysts, hydrotreating catalysts).- Easy - access catalyst loading and unloading ports for convenient catalyst replacement and maintenance, minimizing downtime during catalyst regeneration or change - out.
|
|
Temperature Control
|
- External heating or cooling jackets, often using thermal oil or steam, for precise temperature regulation across the reactor bed. Operating temperature range: 300 - 600°C, with control accuracy of ±2°C.- Multiple thermocouple installations along the reactor length for real - time temperature monitoring and adjustment.
|
|
Pressure Rating
|
- Working pressure: 1 - 5 MPa (gauge), customizable to meet specific reaction pressures in naphtha reforming or hydrotreating processes.- Equipped with pressure - relief valves, safety interlocks, and burst discs to prevent over - pressurization and ensure operational safety.
|
|
Mass Transfer Design
|
- Optimized internal flow distributors and baffles to ensure uniform distribution of naphtha feedstock and hydrogen (in hydrotreating) across the catalyst bed, enhancing mass transfer efficiency and reaction kinetics.- Strategic placement of internals to minimize pressure drop while maximizing contact between reactants and catalysts.
|
|
Product Separation
|
- Integrated separation components (e.g., cyclones, filters) for removing catalyst fines from the product stream.- Optional internal heat exchangers for pre - heating the naphtha feed or cooling the product mixture, improving overall process energy efficiency.
|
|
Control and Monitoring
|
- PLC/DCS - based control systems for automated operation, including flow rate control, temperature regulation, and pressure management.- Real - time monitoring of key parameters (temperature, pressure, flow rate, catalyst activity) using sensors and online analyzers for process optimization and predictive maintenance.
|
|
Applications
|
- Naphtha catalytic reforming to increase the octane number of gasoline components.- Naphtha hydrotreating to remove sulfur, nitrogen, and other impurities, meeting environmental and product quality standards.- Production of high - value petrochemical intermediates from naphtha, such as benzene, toluene, and xylene (BTX).
|
|
Customization Options
|
- Multiple inlets and outlets for feeding naphtha, hydrogen, and other reactants, as well as for product removal and sampling.- Custom catalyst support structures for different catalyst types and sizes.- Integration with upstream and downstream refinery units for seamless process integration.
|
|
Durability Features
|
- Reinforced welds and stress - relieved construction to withstand long - term operation under high - temperature and high - pressure conditions.- Corrosion - resistant coatings and wear - resistant materials for extended service life, especially in hydrogen - and sulfur - containing environments.
|
|
Standards Compliance
|
- Meets international standards such as ASME (for pressure vessels), API (American Petroleum Institute) standards for refinery equipment, and relevant environmental regulations, ensuring quality, safety, and reliability in petrochemical operations.
|
|
Maintenance
|
- Low - maintenance design with modular components for easy inspection and repair.- Regular maintenance guidelines provided to ensure long - term reliable operation, including catalyst life monitoring and preventive maintenance of pressure - bearing components.
