How Should The Petrochemical Industry Select Level Gauges? The Crucial Role of Radar Level Gauges in The Safety And Efficiency of Storage Tanks.

Introduction: Measurement in the Petrochemical Industry Allows No Insufficient Error

In the petrochemical industry, storage tanks are the core of production and also the focus of risk. A single level measurement error can lead to:

Safety Disasters: Overflow, empty tanks, or mixing of incompatible media.

Huge Economic Losses: Inaccurate inventory leading to trade disputes, or incorrect production proportions resulting in the scrapping of entire batches of products.

Compliance Risks: Inability to meet increasingly stringent Safety Integrity Level (SIL) and environmental regulations.

Traditional differential pressure and float-type level gauges often fall short in the face of extreme temperature, pressure changes, and media characteristics. Therefore, seeking a highly reliable, high-precision, and maintenance-free measurement technology has become an industry consensus. Radar level gauges are the ultimate answer to this need.

Typical Petrochemical Storage Tank Challenges and Targeted Solutions for Radar Level Gauges

1. Crude Oil and Heavy Oil Storage Tanks

Challenges: High media viscosity, prone to wax formation, presence of thick oil and gas layers, and convection caused by temperature differences within the tank.

Radar Solutions:

High-Frequency Radar (26/80GHz): Its strong signal penetration effectively overcomes oil and gas interference.

Guided Wave Radar: For very viscous crude oil or crude oil with stratification (oil-water interface), guided wave radar (coaxial or single-cable) is ideal, as its measurements are unaffected by changes in medium properties.

Advantages: Provides stable level and interface measurements, supports Automated Tank District Management (ATG) systems, and enables accurate inventory accounting.

2. Light Oil Product (Gasoline, Naphtha, Aviation Kerosene) Storage Tanks

Challenges: High volatility, high vapor pressure, and the tank's internal vapor space filled with high concentrations of flammable vapors, requiring extremely high explosion-proof instrumentation.

Radar Solutions:

Intrinsically Safe or Explosion-Proof Certification: Radar level gauges generally possess ATEX, IECEx, and other explosion-proof certifications, meeting the requirements for use in Zone 0 and Zone 1 hazardous areas.

Non-Contact Measurement: No moving parts, no sparks generated, ensuring safety in principle.

High-Precision Trade Transfer: Accuracy up to ±1mm, combined with temperature sensors, fully compliant with international standards (such as API standards) for trade measurement requirements.

Advantages: Safe and reliable, the first choice for precision metering in internal floating roof tanks or dome-roof tanks.

3. Liquefied Gas (LPG, LNG) Spherical Tanks/Storage Tanks

Challenges: Ultra-low temperatures (LNG down to -162°C), high pressure, media in a boiling state, and violent liquid level fluctuations.

Radar Solution:

Cryogenic and High-Pressure Resistance Design: Antenna and process seals utilize special materials and structures to ensure no leakage or failure under extreme conditions.

Intelligent Signal Processing: Advanced algorithms filter out interference echoes caused by boiling and turbulence, locking onto the true liquid level.

Advantages: Provides continuous and reliable level and volume data, crucial for preventing overloading and calculating BOG (Bottle-Off Gas).

4. Corrosive Chemical (Acids, Alkalis, Solvents) Storage Tanks

Challenges: Highly corrosive media, placing stringent requirements on the materials used for contacting instruments; polymerization and crystallization sometimes occur.

Radar Solutions:

All-Plastic/PTFE Antennas: For strong acids (such as sulfuric acid and hydrochloric acid), antennas coated with polypropylene or PTFE are provided, offering perfect corrosion resistance.

Non-Contact Measurement: Again highlighting its advantages, the radar antenna does not come into contact with the corrosive media, avoiding the risk of sensor corrosion damage.

Planar Antenna Design: Smooth surface, easy to clean, preventing crystal buildup.

Advantages: Long lifespan, extremely low maintenance costs, ensuring measurement continuity under highly corrosive conditions.

Beyond Measurement: How Radar Level Gauges Empower Smart Petrochemical Plants and Safety Compliance

1. Meeting Functional Safety (SIL) Certification

Modern petrochemical projects have clear SIL level requirements for Safety Instrumented Systems (SIS). Safety-grade radar level gauges, certified by third parties (such as TÜV), provide SIL 2 or SIL 3 level measurement signals for high-high/low-low level interlock shutdowns, adding a layer of "digital insurance" to plant safety.

2. As the Core of Automated Tank Farm (ATG) Systems

Radar level gauges are the "eyes" of the Automated Tank Farm Management System. They upload high-precision level and temperature data to the control center in real time, automatically calculating standard volume, mass, and feed/discharge rates to generate reports. This enables:

Unmanned inspections, reducing labor costs and risks.

Inventory visualization, optimizing the supply chain and cash flow.

Leak detection, providing early warnings of potential leaks through minute level anomalies.

3. Contributing to Environmental Protection and Emission Reduction

Accurate level and vapor pressure measurements help optimize the operation of oil and gas recovery systems. By controlling the breathing losses of storage tanks, radar level gauges indirectly help plants reduce VOC emissions, meeting environmental regulations.
