Metallurgical processes and systems for gas atomization of molten slag and/or molten metals from a metallurgical furnace are integrated with off-gas handling processes and equipment, such that the off-gases are fed to the gas atomization plant for atomizing the molten slag and/or molten metal. The use of by-product off-gases for atomizing molten slag and/or molten metals provides a number of benefits, including elimination of off-gas handling and treatment equipment, centralization and upgrading of heat via atomization to improve heat recovery, prevention of oxidation of granular products of atomization, and reduction of CO.sub.2 emissions. A process for preparing a granular product comprises: feeding a molten material and a by-product off-gas to a dispersion apparatus; and contacting the gas with the molten material in the dispersion apparatus, whereby the molten material is dispersed and solidified by contact with the gas to form the granular product.

The present invention discloses a multiple modular system for the formation of powders, characterized in that it comprises a tower (1) comprising an interchangeable head A selected from the group consisting of a disk spray unit A1; a nozzle spray unit A2; a dual fluid spray unit A3 and a high temperature spray unit A4; and wherein said tower (1) comprises an interchangeable collector installed in the lower part B of the tower selected from the group consisting of collector type 1 (B1), collector type 2 (B2), collector type 3 (B3) and collector type 4 (B4) or combinations of the same.
