How Degassing Chemicals Work: Industrial Solutions for Tank & Pipeline Safety

Introduction

In oil and gas, petrochemical, and manufacturing industries, vapor control and safety are mission-critical especially when handling volatile hydrocarbons. During maintenance, inspection, or decommissioning of storage tanks and pipelines, degassing becomes an essential operation. If not done correctly, residual vapors can reach dangerous levels, leading to explosions, health hazards, or regulatory violations.

Enter degassing chemicals—specialized agents designed to neutralize and displace flammable and toxic vapors. In this article, we’ll explore how degassing chemicals work, why they matter in industrial safety, and how companies like Hasten Cleanse Solution in Texas are helping businesses stay compliant, efficient, and safe.

What Is Degassing?

Degassing refers to the removal or suppression of volatile organic compounds (VOCs), hydrocarbons, and flammable gases from confined or enclosed spaces such as:

  • Oil and fuel storage tanks
  • Pipelines
  • Process vessels
  • Truck and railcar containers

The purpose is to reduce vapor concentrations below the Lower Explosive Limit (LEL), enabling safe entry, inspection, hot work (e.g., welding), or cleaning operations.

Why Degassing Is Critical

  1. Worker Safety
    Without degassing, confined spaces can accumulate explosive or toxic gases. These pose immediate risks such as fire, explosion, and long-term respiratory issues.
  2. Environmental Compliance
    Under regulations such as the Clean Air Act and OSHA’s Confined Space Entry standards, companies are legally obligated to control emissions and provide a safe working environment.
  3. Operational Efficiency
    Effective degassing minimizes downtime by speeding up cleaning, inspection, and maintenance cycles.

How Degassing Chemicals Work

Degassing agents are formulated using surfactants, solvents, and active compounds that chemically or physically remove volatile vapors. Their primary mechanisms include:

  1. Vapor Displacement
    Some degassing chemicals displace volatile gases by saturating the tank with heavier, non-combustible vapors that push hydrocarbons out.
  2. Molecular Bonding
    Advanced degassing solutions bind directly to hydrocarbon molecules, neutralizing their ability to evaporate and form dangerous vapors.
  3. Surface Washing
    Detergent-based degassing agents clean tank surfaces, dissolving residual oil and gas layers that continue to emit VOCs.
  4. LEL Suppression
    Many modern degassing chemicals include additives that specifically suppress LEL values, reducing ignition risk during confined space entry.

Types of Degassing Chemicals

  1. Water-Based Degassing Solutions
    Eco-friendly, low-toxicity, and ideal for general hydrocarbon removal in tank cleaning.
  2. Solvent-Based Degassing Agents
    Used for heavy-duty applications or high-concentration hydrocarbons; highly effective but require more ventilation.
  3. Foam-Based Degassing Products
    Provide additional coverage and vapor sealing for tanks and pipelines where evaporation rates are high.
  4. LEL Scavenging Solutions
    Specialty chemicals used to neutralize flammable vapors and reduce explosive limits.

Application Methods

Degassing chemicals can be applied using several techniques depending on the system and safety protocols:

  • Spray nozzles for tank interiors
  • Circulation or injection systems for pipelines
  • Foam cannons for wide surface coverage
  • Fogging systems for low-access areas

Each method is chosen based on vapor volume, tank size, and operational accessibility.

Best Practices for Safe and Effective Degassing

  1. Pre-Test Vapor Levels: Always use gas detectors to assess VOC and LEL concentrations before and after application.
  2. Use Approved Products: Select chemicals that are EPA-compliant and safe for the target environment.
  3. Ventilate Thoroughly: Maintain airflow even after application to prevent vapor buildup.
  4. Train Staff: Ensure personnel are trained in chemical handling, PPE, and confined space protocols.
  5. Post-Test Verification: Conduct a final LEL reading before re-entry or hot work begins.

Industry Applications

  1. Oil Refineries
    Degassing before tank cleaning or pipeline maintenance ensures compliance and operational safety.
  2. Fuel Storage Facilities
    Prepares tanks for internal inspection and minimizes downtime.
  3. Chemical Manufacturing
    Reduces VOC emissions during shutdowns or equipment swaps.
  4. Rail & Truck Tanker Cleaning
    Supports Department of Transportation (DOT) safety compliance.

Regulatory Compliance: What You Need to Know

In the United States, chemical degassing operations are subject to stringent federal oversight. Companies must ensure their practices align with:

  • OSHA 29 CFR 1910.146 (Permit-Required Confined Spaces)
  • EPA Clean Air Act (VOC and HAP control)
  • NFPA 30 (Flammable and Combustible Liquids Code)

Hasten Cleanse Solution’s degassing products are engineered to meet these regulations, helping clients avoid fines, shutdowns, and safety incidents.

Degassing vs. Venting: What’s Better?

Factor Chemical Degassing Traditional Venting
Speed Fast (hours) Slow (days)
Emission Control High Low
Safety Controlled environment Risk of ignition/vapor escape
Cost Efficient in the long term Labor-intensive

Future of Degassing Technology

The future of industrial degassing is trending toward:

  • Green chemistry: Biodegradable, plant-based formulas
  • AI monitoring: Real-time LEL tracking and response
  • Drone-based application: For remote or dangerous tanks
