Abstract
The method of adding heat to refrigerated rich liquid that accumulates in a reservoir in a distillation column, to prevent the column from flooding, that includes the steps sensing a rise in rich liquid level to predetermined level in the reservoir, removing rich liquid from the reservoir in response to said sensing, to flow to vaporizer apparatus outside a cold box containing said column, adding heat to the removed rich liquid and converting the removed rich liquid into gas, in said vaporizer apparatus, returning said gas to the distillation column, and utilizing heat from the returned gas in the column to remove excess refrigeration from the rich liquid remaining in the column, thereby stabilizing the column against flooding.
