A steam injection nozzle for controlling the flowrate of steam injected into a hydrocarbon containing reservoir comprises a passage extending between an inlet and an outlet, wherein the passage comprises a first, pressure dissipating section and a second, pressure recovery section.

A tank includes a cone-shaped wall formed of steel and attached between a first dome-shaped surface formed of steel and a second dome-shaped surface formed of steel. The cone-shaped wall attached between the first dome-shaped surface and the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.
