Multiple chemical supply line

A method of supplying multiple chemicals in a supply line 1, wherein the chemicals are supplied as discrete slugs A, B, C, i.e. not mixed in the supply line. Chemicals may be supplied in such an order that adjacent chemicals are immiscible and do not react with one another. Alternatively, inert sepa...

Zusammenfassung:	A method of supplying multiple chemicals in a supply line 1, wherein the chemicals are supplied as discrete slugs A, B, C, i.e. not mixed in the supply line. Chemicals may be supplied in such an order that adjacent chemicals are immiscible and do not react with one another. Alternatively, inert separators P may be used between each chemical. The separators may take the form of a solid pig, an inert fluid, an inert gel, a volume of inert gas or ice. At the distal end of the supply line, chemicals may be stored in respective chemical tanks, and the inert separators sent to a waste store.
