I have a problem with overflow titanium tetrachloride. Is used only in ione recipe, byt this recipe not consuming whole chloride and tons of purified tetrachloride storaging in tanks without any usage.

The crafting process is meant to be:
[4x Rutile Ore, 4x Carbon] makes [40x Titanium Tetrachloride]
This in turn is used in Purified titanium tetrachloride:
[80x Titanium Tetrachloride] makes [1x Iron Slurry, 2x Magnesium, 40x Purified Titanium Tetrachloride]
This is then used to craft Titanium Sponge:
[1x Magnesium, 20x Purified Titanium Tetrachloride]

Two cycles of Titanium Tetrachloride to produce on cycle of Purified Titanium Tetrachloride, which in turn is enough for two cycles of Titanium Sponge.

Could you explain a bit more on how you are ending up with overflow? Even with productivity modules the ratios should stay the same.
