Flare Gas Monetization – Sertum Consulting

A significant volume of associated gas is flared globally as a by-product of oil production operations. This gas often remains unutilized due to factors such as limited quantities, lack of pipeline infrastructure, high treatment costs, or the priority placed on rapid oil production.

The disposal of flare gas not only results in energy loss but also imposes additional operational costs, particularly when the gas contains hydrogen sulfide (H₂S), which requires specialized handling.

Leveraging our in-house expertise in gas treatment and collaboration with technology partners, Sertum Consulting transforms this operational challenge into a profitable and sustainable opportunity through several monetization pathways:

Gas Compression
Power Generation
Energy Recovery: Conversion of H₂S into Gypsum A game-changing technology that combines environmental sustainability with economic value creation

Energy Storage through Methanol Production

Gas Compression and Power Generation

Building on extensive experience in the design and construction of production facilities and associated utilities, Sertum Consulting provides customized solutions for a wide range of gas treatment, compression, and power generation applications.

Examples of recent applications include:

Gas treatment and compression for temporary pipeline systems
Gas treatment and compression for gas injection projects
Fuel gas treatment for power generation using both reciprocating engines and gas turbines

Energy Recovery: Conversion of H₂S into Gypsum

A game-changing technology that combines environmental sustainability with economic value creation

innovative project is based on the valorization of the calorific value of H₂S waste gas through a Heat Recovery Steam Generator (HRSG). The process involves burning H₂S-rich waste gas from oil and gas production facilities and subsequently treating the SO₂-rich flue gas to produce Gypsum, a non-hazardous and valuable by-product.

Key Benefits

Environmentally friendly and safe disposal of H₂S
Energy positive process — the plant generates sufficient power for its operation plus a surplus for export
Production of Gypsum, a valuable, non-hazardous by-product that is easy to handle, store, and transport
Enhanced safety: H₂S is immediately converted to SO₂ at the first stage, reducing risk compared to traditional SRU (Sulphur Recovery Unit) plants
Simplified operation and maintenance
Flexible scalability — suitable for small to medium-scale applications with lower capital and operating costs than conventional SRUs

Deployment Readiness: Ready for pilot implementation

Energy Storage through Methanol Production

This project focuses on the valorization of flare gas from remote oilfields by converting methane (CH₄) into methanol (CH₃OH) for fuel blending applications. The process employs a simplified single-step conversion, providing the most direct and efficient pathway to transform flare gas into a stable, transportable liquid fuel.

By converting gaseous methane into methanol, the process effectively stores and transports energy in a safer and more manageable form, enabling utilization of resources that would otherwise be wasted.

Key Values

Environmental benefit through the reduction of routine gas flaring
Economic value recovery from waste gas, enhancing the financial viability of upstream operations
Generation of Carbon Credits under international sustainability frameworks
Regulatory compliance support, helping operators meet environmental standards and emission targets
