Name of the Project
Virginia gas project.

Location
The project spans 187 000 ha of gasfields across Welkom, Virginia and Theunissen, in the Free State, South Africa.

Project Owner/s
Tetra4, a subsidiary of domestic natural gas and helium producer Renergen.

Project Description
The project entails the construction of 52 km of gas-gathering pipeline and cryogenic liquefaction processing facilities.

The aim is to produce all South Africa’s helium requirements and export the balance of production, as well as produce the first liquefied natural gas (LNG) locally available for commercial consumption.

Phase 1 aims to produce 350 kg/d of helium. Output will be increased through the construction of Phase 2, expected in 2025, “arguably making it among the biggest helium projects on the planet", Renergen CEO Stefano Marani has said.

This will deliver more than 0.4-billion cubic feet (bcf) of helium, which, over 19 years, amounts to 7.6 bcf, or just over half its estimated proven and probable reserves.

Phase 1 of the project will produce about 50 t/d of LNG, which is about 75 000 ℓ/d of diesel equivalent. Phase 2 will potentially increase this to the LNG equivalent of about 1 000 000 ℓ/d of diesel, subject to the final agreed design being scoped by Renergen and offtaker Ivanhoe Mines.

Phase 2 allocations will likely result in the project’s transforming into a significant LNG production facility, placing the project more in line with global small- to medium-scale production capabilities.

Phase 2 is intended to have the first stage completed by 2025.

Potential Job Creation
Despite the project’s size, relative to traditional mining operations, it will create an estimated 360 temporary jobs during development and construction, and an estimated 160 permanent jobs once all the clusters have been developed.

Capital Expenditure
The total projected capital expenditure to roll out the first phase of production is estimated at R1-billion, which includes the cryogenic liquefiers.

Planned Start/End Date
Phase 1 of the Virginia project was expected to start producing LNG and liquid helium by the end of 2021, but this was delayed, owing to Covid-19. The revised schedule forecasts the startup of commercial operations in April 2022.

Phase 2 is expected to complete construction in 2025 or 2026.

Latest Developments
Renergen achieved the natural gas-to-plant milestone at its Virginia project on July 8.

This was signified by the opening of the main inlet line from the gas gathering system to the process plant and then to the natural gas filtration and precompression system.

The key objective of introducing gas to plant is to ensure that the plant safety systems can be verified under controlled conditions, before progressing into various areas of the process plant.

The full commissioning and operational testing of the emergency and operational flare systems have also been completed, which is the first integrated run between the pipeline system and process plant.

The flare system tests included pilot and igniter operation and functional tests using product from the process plant. Tests also included the wet gas knockout testing and water collection and recirculation systems.

Final commissioning workstreams will be completed over the coming weeks, with commercial operations starting once customer sites are ready to begin accepting product.

Renergen expects this to occur towards the end of July.

Key Contracts, Suppliers and Consultants
Phase 1:
