Title: Treatment of tributyl phosphate waste
Inventor: MIYAMOTO HITOSHI
IPC: G21F9/06
Filed: 1987-04-30
Abstract: PURPOSE:To decompose a liquid into butyl alcohol and phosphoric acid, by a method wherein the liquid is extracted continuously or periodically from a hydrolysis tank to be passed through a cathode section of a phosphoric acid removing tank, and after the removal of phosphoric acid, it is returned to the hydrolysis tank to promote a decomposing reaction. CONSTITUTION:A high pressure pump 6a is linked to a phosphoric acid removing tank 1 and sucks up pure water 7 to be turned to waster 8, which is sent to a regenerative heat exchanger 3 together with a tributyl phosphorate (TBP) waste liquor 9 fed with a separate high pressure pump 6b as (water plus TBP waste liquor) 10. The temperature of the combined solution is raised with the heat exchanger 3 to about 250-300 deg.C to perform a hydrolysis of the TBP. Thereafter, (the TBP plus the decomposed solution) 11 passes through the heat exchanger 3, a decompression mechanism 12 and a nonregenerative heat exchanger 4 to cool. Thereafter, the solution enters a specific gravity difference remover 5 to recover butyl alcohol 13 alone. On other hand, (water plus a phosphoric acid liquid) 14 is sent to the removing tank 1, where phosphate ions shift to the anode side to turn a anode liquid to a phosphoric acid solution. Water 8 cleared of phosphoric acid is mixed with new TBP again and, then, sent to the heat exchanger 3.
