Section NR 254.091 - Specialized definitions

The following definitions are applicable to the terms used in this subchapter:

(1) "Acid recovery" means sulfuric acid pickling operations that include processes for recovering the unreacted acid from spent pickling solutions.

(2) "Acid regeneration" means hydrochloric acid pickling operations that include processes for regenerating acid from spent pickling solutions.

(3) "Bar, billet, and bloom" means acid pickling operations that pickle bar, billet, or bloom products.

(4) "Batch" means pickling operations which process steel products such as coiled wire, rods, and tubes in discrete batches or bundles.

(5) "Combination acid pickling" means operations in which steel products are immersed in solutions of more than one acid to chemically remove oxides and scale and the associated rinsing operations.

(6) "Continuous" means pickling operations other than batch operations.

(7) "Fume scrubber" means pollution control devices used to remove and clean fumes originating in the pickling operations.

(8) "Hydrochloric acid pickling" means operations in which steel products are immersed in hydrochloric acid solutions to chemically remove oxides and scale and the associated rinsing operations.

(9) "Neutralization" means acid pickling operations that do not include acid recovery or acid regeneration.

(10) "Pipe, tube, and other" means acid pickling operations that pickle pipes, tubes, or any steel product other than a rod, wire, coil, bar, billet, bloom, strip, sheet, or plate.

(11) "Rod, wire, and coil" means acid pickling operations that pickle rod, wire, or coiled rod and wire products.

(12) "Spent acid solution" means solutions of steel pickling acids which have been used in the pickling process and are discharged or removed.

(13) "Strip, sheet, and plate" means acid pickling operations that pickle strip, sheet, or plate products.

(14) "Sulfuric acid pickling" means operations in which steel products are immersed in sulfuric acid solutions to chemically remove oxides and scale and the associated rinsing operations.
