HCl/HBr Synthesis Unit

Positioning and Value Proposition:

We design and supply hydrochloric acid (HCl) and hydrobromic acid (HBr) synthesis units for highly corrosive industrial environments. Our services include process engineering, 3D modeling, the supply of various equipment, assembly, on-site integration, on-site commissioning, and long-term technical support throughout the facility’s lifecycle.

Our value proposition is built on fundamental pillars that set us apart in the market:

"Brand-Agnostic" Expertise:

We offer a service that is independent of the graphite equipment manufacturer's brand.

Thanks to our technical expertise in optimizing, repairing, and maintaining existing units from various international manufacturers (MERSEN, SGL, Graphite India, etc.).

‍‍

Technical Support:

Support throughout the entire lifecycle and long-term partnership (inspection, maintenance, troubleshooting).

‍

Process Control and Technical Performance

‍

The performance, purity, and reliability of our units depend on rigorous control of the synthesis process, which is based on a controlled exothermic reaction between hydrogen (H₂) and chlorine (Cl₂) or bromine (Br₂).

‍

Description of the Standard Procedure

A typical process configuration includes the following key steps to ensure optimal and safe production:

• Controlled feedof H₂ and Cl₂/Br₂ reagents.
• Synthesis in a dedicated burner or reactor with precise control of the ratio and temperature.
• Rapid coolingof the reaction gases to stabilize the product.
• Downstream processing for the production of dry gaseous HCl/HBr or an aqueous solution at the required concentration.
• Wastewater treatment through gas scrubbing and neutralization of liquid effluents, in accordance with environmental standards.

‍

Key Performance Indicators

Our units deliver high and measurable performance:

• Pureté Exceptionnelle : teneur en chlore libre < 1 ppm
• Operational Flexibility (Turndown): Stability from 5% to 100% load without affecting quality.
• Concentration Accuracy: Production ofaqueous acid up to a concentration of 38% w/w, with integrated cooling systems for optimal thermal management.‍
• High Availability: The maintenance-oriented design facilitates service, minimizes downtime, and maximizes the unit's availability.

This performance is based on advanced technological choices and high-quality materials .

‍Fundamental Technological Differentiators

Our competitive advantage is based on the integration of proprietary technologies and strategic material choices that address the industry's most common challenges, such as corrosion, thermal shock, and recurring failures.

‍

Exclusive Silicon Carbide (SiC) Burner Technology

Standard graphite burners are a chronic source of breakdowns, leading to costly production downtime and extensive maintenance.

To address this issue in a sustainable way, we have developed a proprietary silicon carbide (SiC) burner technology.

This innovation offers significant advantages:

• Superior Resistance: SiC offers exceptional resistance to chemical deposits (salts, oils, moisture) and thermal shock,
• Durability: The robustness of SiC significantly extends the service life of the equipment and considerably reduces the frequency of maintenance cycles

Advanced Materials and Integrated Safety

We select advanced materials, such as high-density impregnated graphite, to optimize the corrosion resistance and service life of heat exchangers and columns.

Safety is built in from the design stage thanks to our burner management system (BMS), which is based on our dedicated safety PLCs. This approach places safety at the heart of the engineering of every installation.

These innovations are being implemented in both new units and modernization projects.

Portfolio of Solutions: New Projects and Modernization

‍

Our expertise enables us to offer a comprehensive range of solutions, from the construction of entirely new facilities to the targeted optimization and modernization of existing ones .

EPC Approach for New Installations

Our key deliverables include:

• Engineering: Comprehensive basic and detailed design studies, including P&IDs, 3D modeling, and risk analyses (HAZOP/HAZID).

‍

• Manufacturing and Supply: "Plug-and-play" skid-mounted units for simplified installation, instrumentation, and control systems.

‍

• On-Site Services: Installation supervision, commissioning, performance testing, and training for operators and maintenance personnel.

‍

‍

‍

Modernization and Optimization Services

‍

Modernizing existing assets is one of our specialties. We work on units of all brands to improve their performance, safety, and compliance.

• Burner Replacement: Replacement of faulty competitors' burners with our highly durable SiC technology.

• BMS Modernization: Implementation of burner management systems (BMS) compliant with ISO 13577-2 (EN 746-2) and SILstandards .‍

• Capacity Increase: Optimization of absorption columns and heat exchangers to increase flow rate without replacing the entire unit.

• Emissions Control: Exhaust gas scrubbing systems designed to meet the strictest environmental regulations (BREF/BAT).

‍

‍

‍

‍

Automatic ignition: via pilot burner and dedicated control panel — safe, repeatable startup that complies with ISO 13577-2.

‍

• The system automatically controls the purge, ignition, and flame monitoring sequences, while monitoring gas and process safety systems. This automation reduces operator risks, improves startup stability , and ensures higher equipment availability.

‍

• Designed in accordance with the requirements of ISO 13577-2, it ensures compliant and safe operation and is suitable for demanding industrial environments.

‍

‍

‍

Energy Recovery

‍

We integrate heat recovery systems to convert heat into process steam (up to 10 barg).

This transforms “waste” into a useful resource.

‍

‍

Process Safety and Regulatory Compliance

The pillars of our safety approach include:

• Risk analyses (HAZID / HAZOP) to identify and manage critical scenarios.
• Safety interlocks and cause-and-effect logic that ensure safe automatic shutdowns.
• Purge, inerting, and ventilation systems to ensure safety during transient phases.
• Leak detection and emergency management for a rapid response in the event of an incident.

‍

We guarantee that our designs comply with the most relevant international standards and codes, including PED, ASME, AD2000, and ATEX.

‍

On-site Technical Expertise

We provide support throughout the system's entire lifecycle to ensure long-term performance, maximum reliability, and uncompromising safety.

• ‍Diagnostic audit:
  
  • Vibration analysis, flame stability control, and thermal imaging

• Maintenance Support:
  • Cleaning the burner while it is running by injecting steam to prevent unplanned shutdowns
• Troubleshooting
  
  • ‍SolvingFlame Arrestor Clogging Problems Using an Advanced Technique for Removing Moisture (H₂ and Cl₂)
