Abstract
An absorber-crystallizer tower is provided with improved means for spraying aqueous solution into a reactive gas to saturate the solution from which the product crystalizes and with improved means for removing scale from the crystal containing suspension which is formed. The apparatus has no scale sensitive internal surfaces and operates continuously without substantial scale build-up.
