| titleOfInvention | Process for working up acid resins |
| abstract | A process is disclosed for processing environmentally harmful stored acid sludge, in particular those produced in the distillation of waste oil and tar, the aim of the process being to satisfy both environmental and economic requirements. This is achieved with a process involving the following consecutive process steps: conversion of the acid sludge into a sulphuric suspension by the addition of dilute sulphuric acid; addition of an oxidising agent to convert any sulphide and sulphite ions to sulphate; separation of the sulphate and any solids which may be present; separation of the liquid residues into organic and inorganic fractions. |
