Filed: 1943-10-20
Abstract: 575,776. Regenerating pickle liquor. SWINDIN, N. Oct. 20, 1943, No. 17278. [Classes 1 (ii) and 1 (iii)] [Also in Group II] Hot waste pickle liquor is cooled and settled, stripped of volatile acid, if any, in a preheater and evaporated by direct hot gas contact in a crystalliser. The partly dehydrated ferrous salt deposited is removed in a separator and sufficient regenerated sulphuric acid is fed back to the pickling tank to maintain it below the ferrous salt precipitation point. As shown in Fig. 1 pickle, initially containing 10-15 per cent. sulphuric acid and 1-5 per cent. volatile acid, e.g., hydrochloric, hydrofluoric or nitric acid, maintained at 70 ‹C. in tank 1 is pumped to the conical settler 6 maintained at 60‹C. Deposited dirt and ferrous salt are periodically discharged to a filter 11. The liquor overflows through a junction box 13 to a preheater 14 kept at 90‹C and thence to a crystalliser 15 kept at 100‹C. by a submerged flame burner 43 fed with air and gas, separately or premixed, by a compressor 45. Deposited ferrous salt passes to a centrifugal 54 and is discharged to a bin 56. 30-40 per cent. sulphuric acid flows from the crystalliser to the pickle supply tank 27 which may also receive acid from the centrifuge and preheater. The crystalliser 15 may receive make up sulphuric acid from tank 47 and liquor from filter 11. The preheater vapours containing volatile acid are trapped and concentrated in a tray tower 21 supplied at 23 with, e.g., water or hydrochloric acid. Weak acid is diverted from one of the bottom trays through lute line 24 back to the preheater, the concentrated acid passing via tank 25 to the supply tank 27. When volatile acid is not present the preheater and cascade tower are dispensed with. The hot crystalliser vapours may be used to heat the pickling tank 1, the preheater 14, or be passed to the tower 21. The ferrous salt may be sprayed on the centrifuge with steam, water, or sodium chloride solution from tank 57, the filtrate in the latter case passing to the supply tank 27. Accumulated sodium sulphate may be removed from the pickle liquor by cooling. Specification 551,528, [Group XXVIII], is referred to in the Provisional Specification.
