Installation of CO₂ Capture Technology

The project involves the installation of a state-of-the-art CO₂ capture system using advanced amine technology. This system has been specifically chosen for its ability to handle exhaust gases with high oxygen content (up to 15%) and to efficiently capture CO₂ with a high reaction rate.

The installation includes several key components, such as a selective catalytic reduction (De-NOx) unit, exhaust gas scrubbers, MEA reboilers, and a comprehensive CO₂ purification system. Each component is being carefully integrated to maximize CO₂ capture efficiency and ensure the production of high-purity CO₂.

Automation and Control

A fully automated control system is being implemented to monitor and manage the CO₂ capture process. The system includes advanced sensors, PLCs, and an HMI interface, allowing for real-time monitoring and control of all key parameters.

The control system is designed to optimize energy use, reduce operational costs, and ensure consistent production of high-quality CO₂.

Efficiency Improvements

The project is successfully reducing the energy consumption of the CO₂ capture process by utilizing heat recovery from the MEA reboiler, significantly lowering the energy required for CO₂ regeneration.

The advanced amine technology reduces the need for steam and other energy inputs, contributing to a lower overall carbon footprint for the facility.

Production Capacity and Quality

The CO₂ capture system is designed to handle an exhaust gas flow of approximately 14,700 kg/h, with a CO₂ output rate of 1,000 kg/h at a purity of at least 99.9%.

The system includes multiple stages of purification, including drying, filtration, and distillation, to ensure the highest possible quality of CO₂, suitable for food-grade applications.

Methane Liquefaction Evaluation

In addition to CO₂ capture, the project is also evaluating the potential for methane liquefaction from flare gas. Tysagaz is an operator of a small groups of wells. The volume of associated petroleum gas coming from flare gas is insufficient to justify the costs of infrastructure required to connect to gas pipelines or transport gas to existing processing plants.

Therefore, a cost-effective solution being considered is to process and liquefy the flare gas directly at the oil fields using new liquefaction technology. This would enable the efficient capture and utilization of methane, transforming what would otherwise be wasted into a valuable resource.

Project Progress and Expectations

As the installation and integration of the CO₂ capture system continue, the project is already demonstrating a significant reduction in greenhouse gas emissions at the Tysagaz facility. The ongoing work aims to achieve its goal of producing high-purity CO₂ while simultaneously reducing the energy consumption and operational costs of the facility.

The project is on track to be completed within the expected timeline, and the system is expected to provide a reliable source of food-grade CO₂ for commercial use once fully operational.
