Pharmaceutica

I. Applications of Oxygen in Pharmaceuticals

1. Cell Culture and Bioreactions

• Oxygen is essential for cellular respiration and metabolism. In biopharmaceutical production (e.g., antibodies, vaccines), precise oxygen control maintains cell viability and promotes product synthesis.

• Certain enzymatic reactions (e.g., cholesterol oxidase-catalyzed reactions) rely on oxygen as a substrate; high-purity oxygen enhances reaction efficiency and specificity.

• High oxygen concentrations improve microbial metabolic efficiency in fermentation processes (e.g., glucose fermentation), increasing yield.

2. Chemical Synthesis and Process Optimization

• Oxygen acts as an oxidant in drug synthesis, accelerating reaction rates and improving yield. For example, enzymatic oxidation reactions (e.g., cholesterol oxidase-catalyzed reactions) depend on high-purity oxygen to ensure specificity and efficiency.

• Oxygen is used as a combustible gas auxiliary in ampoule sealing processes.

3. Environmental Control and Protection

• Oxygen regulates tank atmospheres in fermentation and cell culture to prevent contamination or oxidative stress.

• High-purity oxygen is used for drying medical equipment and cleaning sterile areas, ensuring pollution-free production environments.

4. Medical Applications

• Medical-grade oxygen (93%-99.5% purity) treats respiratory diseases (e.g., hypoxia, respiratory failure) and serves as the basis for hyperbaric oxygen therapy.

• Oxygen is required for producing pharmaceutical excipients (e.g., aerosol propellants).

II. Advantages of On-Site PSA Oxygen Systems as Oxygen Sources

1. Economic Efficiency and Cost Control

• On-Demand Supply: Customizable oxygen flow and purity match production needs, avoiding waste or shortages.

• Cost Reduction: Compared to liquid oxygen or cylinder oxygen, PSA eliminates transportation and inventory costs, offering lower long-term expenses.

2. Stable and Controlled Oxygen Quality

• High Purity: PSA technology produces oxygen with 90%-99.5% purity, meeting strict pharmaceutical requirements (e.g., high-purity oxygen for cell cultures).

• Real-Time Monitoring: Automated systems ensure continuous, stable oxygen supply with consistent pressure, preventing production disruptions or material loss.

3. Safety and Compliance

• Eliminated Storage Risks: On-site oxygen generation removes the need for hazardous tanks, reducing explosion/leak risks and aligning with GMP safety standards.

• Customized Adaptation: Flexible configurations meet diverse oxygen demands while complying with pharmacopoeia limits on impurities (e.g., moisture, oil, microbes).

4. Environmental Sustainability

• Low Energy Consumption: Advances in PSA technology reduce energy use, and zero emissions support green pharmaceutical practices.

• Carbon Footprint Reduction: Eliminating liquid oxygen transportation cuts carbon emissions, aiding pharmaceutical companies’ “dual carbon” goals.

5. Process Optimization and Efficiency

• Precise Control: Adjustable oxygen concentration and flow optimize parameters in cell culture, oxidation reactions, etc., enhancing product consistency.

• Compact Design: Space-saving PSA units fit constrained factory layouts, and modular designs facilitate scalability.
