Head Pitiylin I.N., Registration Date 24-03-2004 Organization Ukrainian State Researsh Institute for Carbochemistry popup.description2 In connection with the increased requirements of consumers to alkali metal ions in coal tar products a work has been undertaken to study the hydrogen potential in coal tar and ammonia tar liquor during condensation and preparation for processing in the recovery shop, sampling points were chosen and agreed with the Client with consideration of maximum active zones in the system "tar-liquor", the causes of pH variation were found and the components of the chemical composition were determined which are responsible for alteration of hydrogen ion concentration. Two concepts are proposed to potimie the hydrogen potential in coal tar (reducing to a level of 6,5-7,0). Product Description popup.authors popup.nrat_date 2020-04-02 Close
