Practical considerations in the concentration and recovery of spent nitration acids
Abstract
Most organic nitrations employ sulphuric acid or oleum in the nitration acid. Even in rare nitric acid only nitrations, sulphuric acid is used as the dehydrating agent to produce 99% nitric acid. The used sulphuric acid is discharged in a diluted form contaminated with organic components and nitric/nitrous species. Pressures are emloyed to reconcentrate and reprocess such spent acids. Acid recovery and concentration is expensive. This paper discusses some of the aspects which must be considered when contemplating acid recovery. In the current industrial climate, acid recovery and recycle should be regarded as an integral part of a nitration process development rather than an afterthought. Case histories will be given in which such considerations influenced the course of the development of the nitration process itself. Emphasis will be placed on the importance of well planned bench and pilot scale test programmes.
