The Tamar Emission Reduction Project

The Tamar Project is the major supplier of natural gas to Israel. The main processing facility for the Tamar Project is an offshore platform. Since Tamar’s natural gas is dry and sweet it requires minimal treatment, which focuses on separating the gas from fluids, and desiccating it to the specifications required by the Israeli regulator. Ultimate desiccation is achieved by flowing the gas through Tri-Ethylene Glycol (TEG), which absorbs the water from the flow stream. The TEG is recycled by heating it to the point where the water evaporates.

A similar recycling-by-boiling process is performed on the platform for Mono-Ethylene Glycol (MEG), which is injected into the wells to prevent hydrates formation in the subsea system.

The original installation of these reboiler systems routed the vapors from the boiling process to the atmosphere via individual vent stacks. Following a sampling campaign in 2017 of the MEG and TEG vents and a dialogue with the environmental authorities, Tamar launched a massive effort to reduce pollutants emissions, by as much as 98%.

The system became fully operational on March 31, 2019. Periodic sampling conducted since shows over 98% reduction in BTEX and NMVOC emissions from the specified vents.
