Process and Piping design Solutions for Liquid Oxygen Storage

• Tank farm design: Implementation of two horizontal cryogenic tanks with a total capacity of 500 m³ (2 x 250 m³).
• Auxiliary infrastructure development: Construction of all necessary support systems to facilitate the efficient storage and handling of liquid oxygen.
• Technological schemes: Design of intricate systems for product reception, storage, and dispensing, including a gas filling rack with three connection points for tanker trucks.
• Pipeline assemblies: Installation of pipelines outfitted with shut-off, safety, and control valves for secure operations.
• Vaporizer systems: Systems to maintain pressure and facilitate the safe dispensing of liquid oxygen.
• Pump units: Both working and backup units designed for effective liquid transfer.
• Control and automation systems: Systems for managing the entire technological process.
• Personnel facilities: A modular operator building equipped with heating, ventilation, and essential sanitary conditions for staff.

Safety and Compliance

Given the oxidative nature of oxygen, our project emphasizes stringent safety measures such as strict adherence to standards, installation of safety valves and bursting membranes to prevent overpressure, and design of grounding systems to mitigate static electricity hazards.

The design project for high hazard category facilities demands safety measures and compliance with technical regulations. We adhere to established standards, including HAZOP (Hazard and Operability Study) and HAZID (Hazard Identification), which are important in identifying potential risks and ensuring safety throughout the project lifecycle.

HAZOP and HAZID Standards

HAZOP involves a systematic examination of the intended operations to identify potential hazards by analyzing deviations from the intended process. This ensures that risks are managed proactively.

HAZID is an initial assessment intended to identify hazards through a high-level review of the project's design and operations, facilitating early mitigations before detailed planning begins.

Handling Extreme Temperatures

Liquid oxygen is stored at temperatures of -196°C, necessitating special considerations:

• Materials: Alloy steels and advanced insulation solutions to prevent brittle fractures.
• Cryogenic Equipment: “Vessel-in-vessel” construction using vacuum-perlite insulation to minimize evaporation to less than 0.4% per day.

Automation

Our automated control systems continuously monitor tank levels and pressures, shutting down pumps at critical thresholds to prevent incidents, ensuring a high level of operational safety.

Logistics scheme

The project requires a complex logistics scheme to facilitate product intake from stationary air separation units and tanker trucks, alongside secure dispensing to consumers through a universal filling rack equipped with metering devices.

This project is not merely about constructing storage tanks; it represents the establishment of a fully automated, secure technological complex dedicated to handling one of the most sensitive materials: liquid oxygen at extremely low temperatures.

We provided end-to-end solutions from reception and storage to controlled dispensing, all while maintaining the highest safety and reliability standards.
