The global market for degassing services is a specialized, regulation-driven segment currently estimated at $3.2 billion USD. Projected to grow at a 5.2% CAGR over the next three years, this market is fueled by stringent environmental mandates and aging industrial infrastructure requiring frequent maintenance. The primary opportunity lies in leveraging new vapor recovery technologies to meet increasingly strict ESG targets, while the most significant threat remains price volatility tied to fluctuating energy and skilled labor costs. This brief provides a detailed analysis to inform our strategic sourcing approach for this critical maintenance category.
The global Total Addressable Market (TAM) for degassing and vapor control services is estimated at $3.2 billion USD for 2024. Growth is steady, driven by non-discretionary maintenance, repair, and operations (MRO) spending in the chemical and oil & gas sectors. The market is projected to expand at a compound annual growth rate (CAGR) of est. 5.2% over the next five years, reaching approximately $4.1 billion USD by 2029. The three largest geographic markets are 1) North America, 2) Europe, and 3) the Middle East, collectively accounting for over 75% of global demand.
| Year | Global TAM (est. USD) | CAGR |
|---|---|---|
| 2024 | $3.2 Billion | — |
| 2026 | $3.5 Billion | 5.2% |
| 2029 | $4.1 Billion | 5.2% |
Regulatory Compliance (Driver): Stringent air quality regulations from bodies like the U.S. Environmental Protection Agency (EPA) and the European Union's Industrial Emissions Directive are the primary demand driver. Rules governing Volatile Organic Compound (VOC) emissions and confined space entry (OSHA) make professional degassing a non-negotiable requirement for safe and compliant plant turnarounds and inspections.
Aging Infrastructure (Driver): A significant portion of global refining, chemical processing, and storage tank infrastructure is over 30 years old. This necessitates more frequent maintenance, inspection, and repair cycles, directly increasing the demand for degassing services to prepare equipment for "hot work" or human entry.
Industrial Production & Turnarounds (Driver): High utilization rates in end-markets (e.g., chemical, oil & gas) correlate directly with the need for planned shutdowns and turnarounds (TARs). These large-scale events are a major source of revenue for degassing service providers.
Skilled Labor Shortage (Constraint): The service is dependent on technicians with specialized training in handling hazardous materials and operating complex equipment. A persistent shortage of qualified field personnel is driving up labor costs and can limit supplier capacity during peak demand periods.
Capital Intensity (Constraint): The high cost of acquiring and maintaining specialized equipment, such as portable vapor combustion units (VCUs) and vapor recovery units (VRUs), creates a significant barrier to entry and contributes to market concentration among a few large players.
Barriers to entry are High, due to significant capital investment in equipment, stringent safety certifications (e.g., ISNetworld, Avetta), and the need for established Master Service Agreements (MSAs) with major industrial clients.

⮕ Emerging/Niche Players * Zeeco: Primarily an equipment manufacturer (flares, thermal oxidizers) that also offers rental and service, specializing in complex combustion solutions. * Cimarron (including Aereon): Focuses on emissions control equipment and services, with a growing emphasis on vapor recovery units (VRUs) for ESG-conscious clients. * Thompson Industrial Services: A strong regional player in the U.S. Southeast, competing on service agility and local presence. * Anco-Eaglin: Specialist in tank cleaning and maintenance, often subcontracting for degassing or providing it as part of a bundled service.
Pricing is typically project-based, quoted on a lump-sum or a time-and-materials (T&M) basis. The price build-up consists of three main components: 1) Equipment Day Rates (for VCUs, blowers, hoses), 2) Labor Costs (field technicians, supervisor), and 3) Consumables & Ancillary Charges (mobilization/demobilization, fuel, nitrogen, waste disposal). For large turnaround events, suppliers may offer volume discounts or bundled service rates.
The most volatile cost elements are directly tied to commodity and labor markets. Procurement should scrutinize these inputs closely during negotiations. 1. Labor: Field technician wages have seen significant upward pressure due to skill shortages. Recent Change: est. +6-8% (YoY). 2. Fuel (Propane/Natural Gas): Used to power the combustion units. Price is tied directly to energy market indices. Recent Change: +/- 30% (trailing 12 months). 3. Liquid Nitrogen: Often used for inerting and purging tanks. Price is influenced by air separation unit (ASU) operating costs, which are energy-intensive. Recent Change: est. +10-15% (YoY).

Demand for degassing services in North Carolina is moderate but consistent, driven primarily by the state's chemical manufacturing clusters, bulk fuel storage terminals (e.g., Greensboro, Selma), and pharmaceutical production facilities. The demand outlook is stable, tied to routine maintenance schedules rather than large-scale greenfield projects. Local capacity is adequate, served by the national Tier 1 suppliers (Clean Harbors, Veolia) operating from regional depots in the Southeast, supplemented by regional specialists like Thompson Industrial Services. The labor market for skilled technicians is competitive but less constrained than in the Gulf Coast. The regulatory environment, enforced by the NC Department of Environmental Quality (NCDEQ), is mature and aligns closely with federal EPA standards, creating a predictable compliance landscape.
| Risk Category | Grade | Justification |
|---|---|---|
| Supply Risk | Medium | Market is concentrated. While national players have mobile fleets, simultaneous major turnarounds in a region can strain local equipment and labor availability. |
| Price Volatility | High | Direct and immediate exposure to volatile fuel, nitrogen, and skilled labor markets. Surcharges are common and can be significant. |
| ESG Scrutiny | Medium | The service is an environmental control, but the method (combustion vs. recovery) is under increasing scrutiny. Emissions from VCUs are a reputational risk. |
| Geopolitical Risk | Low | Service is delivered regionally with domestic labor and largely domestic equipment. Indirect risk exists via global energy price shocks affecting fuel costs. |
| Technology Obsolescence | Low | Core combustion technology is mature. Innovation is incremental (efficiency, monitoring), not disruptive. VRU is a parallel, not replacement, technology. |
Consolidate Regional Spend & Index Pricing. Initiate a regional RFP to consolidate spend across our Southeast facilities with two pre-qualified suppliers. Negotiate 24-month fixed rates for equipment and labor, but allow for fuel/nitrogen adjustments based on a transparent, third-party index (e.g., OPIS, ICIS). This will secure capacity, reduce administrative overhead, and protect against opaque or excessive surcharges.
Mandate Dual-Technology Bidding for ESG Gains. Require that all bids for degassing projects >$50k include proposals for both a standard Vapor Combustion Unit (VCU) and a Vapor Recovery Unit (VRU), where technically feasible. This will force suppliers to compete on sustainability metrics, drive adoption of superior recovery technology, and may generate value from recaptured product while reducing our Scope 1 emissions.
