Abstract:
     This invention relates to the method for recovering carbon black from the waste water in the process of synthetic ammonia and methyl alcohol, heavy oil is used as raw material, said carbon black is adsorbed with water, its content is 0.5-3%. Prior process is adopting the method of naphtha extraction, it is easy to stop the vent of equipment. In this invention, it uses filter-pressing and drying method, it has advantages of simple in process and apparatus, it is easy to operate, without pollution, lower investment. Carbon black which is produced by vaporization in Shell vaporizer is recovered by this method, it can be used as functional material in the high power battery, and used for cable, various manufactures of rubber and conductive plastics. The availability of carbon black is higher 10 times than that it is recovered by prior method.
