Product Specification
Custom Distributor For Strong Acid
Precision-engineered anodic protection acid distribution equipment designed for regulated processing of high-strength sulfuric acid (concentrations above 96%) and oleum in demanding industrial environments.
Product Overview
This specialized equipment is typically deployed in sulfuric acid alkylation sections at petroleum refining complexes and absorption/drying stages of acid production facilities. The system ensures even fluid dispersion across vessel internals while employing electrochemical passivation techniques to resist aggressive acid media.
Core Functionality
Liquid Spreading Mechanism: Internal configuration features interconnected collection channels, precision-formed overflow lips, and distribution apertures. The unit receives incoming acid streams and divides them into numerous individual flows that fall uniformly onto underlying packing material.
Surface Protection via Anodic Methods: Standard metallic materials undergo rapid degradation in concentrated sulfuric acid at elevated temperatures. The system overcomes this through strategic alloy selection combined with an impressed anodic protection system.
Technical Concept: A regulated electrical current is applied to the metal surface, maintaining its potential within a passive region. This mechanism encourages formation and continuation of an unbroken, securely bonded shielding film that insulates the base metal from corrosive fluid.
Operational Result: This technique restricts material loss to minimal rates (commonly under 0.1 mm per year), resulting in extended equipment lifespan and prevention of metal impurities entering the acid flow.
Construction Features
- Materials Used: Fabricated from austenitic stainless steel grades (including 304L and 316L) selected for appropriate response to anodic conditioning and capability to withstand acid exposure
- Flow Design: Incorporates carefully established weir heights and opening sizes to preserve uniform liquid distribution across the entire operating envelope
- Assembly Approach: Produced in modular pieces that move through standard vessel access points, permitting interior installation without welding work at site location
- Electrical Configuration: Contains specially situated electrode components within the acid stream to complete the protective circuit without affecting distribution patterns
Operational Advantages
- Extended Service Life: Lowers ongoing upkeep expenses through effective handling of corrosion-related deterioration
- Acid Purity Assurance: Prevents metal ions from mixing with acid flow, meeting purity criteria for sensitive downstream applications
- Process Efficacy: Supports regular wetting of column internals, aiding optimal mass transfer and separation functions
- Structural Robustness: Maintains mechanical soundness during continuous operation under high temperatures and aggressive chemical conditions
Common Applications
- Alkylation Facilities Using Sulfuric Acid Catalyst
- Drying and Absorption Towers in Acid Manufacturing Operations
- Acid Temperature Control and Circulation Installations
