| Abstract: | The working principle and characteristics of steam jet pump and liquid- ring vacuum pump are introduced. And engineering de- sigma examples are presented to discuss the Maoming 5000 kt/a atmospheric and vacuum distillation unit transformation process of vacuum dis- tillation tower mechanical vacuum system, process piping and process of automatic control and chain control system, etc. Project implemen- tation justified the retrofit scheme of liquid - ring vacuum pump instead of the secondary steam ejector, more flexible in operation. Compre- hensive energy consumption of unit reduce kgEo 0. 334/t, least in investment and eftlcient in energy saving and environmental protection. At the same time, it puts forward the requirements in equipment selection and piping layout for reference. |
