Hydrogen Bromide Compressor

Hydrogen bromide (HBr) is a colorless, intensely irritating, highly corrosive and asphyxiating gas. Its core risk lies in the fact that it forms highly corrosive hydrobromic acid upon contact with water, and under certain conditions, bromide ions can drive pitting and corrosion of stainless steel even more aggressively than chloride ions. In industrial applications, it is a key raw material for organic synthesis, pharmaceutical intermediates, and semiconductor etching processes, imposing extremely high demands on gas purity and equipment reliability. Therefore, for the compression of hydrogen bromide, absolute sealing and comprehensive corrosion-resistant design must be taken as the lifeline to ensure safety and prevent contamination.

dvantages of Hydrogen Bromide Diaphragm Compressor

01

Absolutely Oil-Free and Zero Leakage Guarantee:

The unique metal diaphragm completely physically isolates the process gas from the hydraulic oil system, achieving 100% oil-free compression. The entire gas chamber adopts a static sealing structure, fundamentally eliminating the risk of hydrogen bromide gas leaking outward or external impurities penetrating inward, perfectly meeting the extremely high purity requirements of semiconductor etching and similar applications.
02

Intrinsically Safe Corrosion-Resistant Platform:

All flow-wetted components can be manufactured from high-grade corrosion-resistant alloys. The gas only contacts carefully selected anti-corrosion surfaces, avoiding the complex corrosion and wear issues associated with dynamic seals in reciprocating compressors. This results in long equipment life and significantly extended maintenance intervals.

Key Design Points for Hydrogen Bromide Diaphragm Compressor

01

Full-Series Corrosion-Resistant Materials for Flow-Wetted Parts:

All components in contact with hydrogen bromide, including the diaphragm head, cylinder head, gas valves, internal piping, and flanges, must be made of materials resistant to hydrobromic acid corrosion. SS316L stainless steel is the basic choice. For extreme conditions with high moisture content or other oxidizing impurities, evaluation and upgrading to duplex stainless steel or nickel-based alloys are necessary. All stainless steel components must ensure sufficient corrosion allowance (typically not less than 2 mm) and undergo thorough degreasing, cleaning, and passivation treatment.
02

Core Diaphragm Material and Rupture Monitoring:

The diaphragm is the core component for isolation and sealing. Materials with excellent corrosion resistance in hydrogen bromide environments and high fatigue strength, such as special alloys like Inconel 718, must be selected. A standard three-layer diaphragm structure with a diaphragm rupture alarm device is required. When the middle diaphragm ruptures, the pressure sensor immediately triggers an alarm for maintenance, while the outer diaphragm still ensures no gas leakage, providing dual safety protection.
03

Integrated Safety Discharge and Monitoring System:

Exhaust gas containing hydrogen bromide from the safety valve must never be discharged directly into the atmosphere or a flare; it must be directed to a dedicated caustic scrubber for neutralization treatment. A fixed hydrogen bromide gas detector probe shall be integrated into the compressor skid to monitor the ambient concentration in real-time and interlock with the ventilation system. Simultaneously, continuous monitoring of cooling water flow, oil pressure, and pressures and temperatures at each stage shall be conducted, with comprehensive alarm and shutdown interlock logic configured.

Advantages of Hydrogen Bromide Reciprocating Compressor

01

Strong Flow and Pressure Adaptability:

Reciprocating compressors can provide a wider flow range and a higher single-stage compression ratio than diaphragm compressors, making them suitable for boosting and transporting large volumes of hydrogen bromide gas in large-scale chemical production, with a better investment cost-benefit ratio.
02

Mature and Reliable Enhanced Corrosion Protection Architecture:

Based on our company's successful experience with hydrogen sulfide, hydrogen chloride, and similar projects, a complete set of enhanced corrosion protection solutions can be customized for hydrogen bromide service. From the cylinder and piston to the piston rod and packing, every component in contact with the medium undergoes targeted material upgrades and process treatments to ensure long-term stable operation under harsh conditions.

Key Design Points for Hydrogen Bromide Reciprocating Compressor

01

Fully Corrosion-Resistant Cylinder and Piston Assembly:

The cylinder body can be designed with a lined 316L stainless steel cylinder liner or directly use a solid stainless steel cylinder. The piston body should abandon aluminum and be made of forged stainless steel (e.g., 304). Piston rings and rider rings shall use corrosion-resistant polymer materials such as filled PTFE or PEEK to achieve completely oil-free lubrication, avoiding oil contamination and the formation of corrosive by-products.
02

Special Protection and Hardness Control of Piston Rod:

The piston rod is one of the weakest links in corrosion protection. The base material should be a precipitation-hardening stainless steel such as 17-4PH. The surface must be coated with a dense, high-hardness wear- and corrosion-resistant coating such as High Velocity Oxygen Fuel (HVOF) sprayed tungsten carbide, and the hardness of the substrate and heat-affected zone must be strictly controlled within the range of HRC 37–41 to resist wear and corrosion while suppressing the tendency for sulfide stress corrosion cracking (SSC).
03

Nitrogen Buffer Seal and Closed Leak Management:

A nitrogen buffer packing system shall be adopted, with pure nitrogen introduced as a barrier gas to effectively prevent hydrogen bromide gas from leaking along the piston rod into the crankcase. The trace gas leaking from the packing, together with the buffer gas, shall be extracted and directed into a closed leak collection vessel, ultimately sent to the exhaust gas treatment system. This design achieves controlled and manageable leakage, greatly enhancing on-site safety.
