Abstract: A flare tank 10 comprises a container 12 having a fluid inlet 14, a fluid outlet 16 and a fluid flow path between the inlet 14 and the outlet 16. A baffle plate 20 is provided in the container 12 between the inlet 14 and the outlet 16. The baffle plate 20 extends transversely relative to the flow path for forming at least a partial barrier to fluid flow in the flow path. A gas outlet, e.g., a chimney stack 18, is located on the container 12 for the discharge of gas separated from the fluid. A burner 46 is provided for the combustion of combustible gas passing through the outlet 18.
