| Abstract: | The working principle of dry gas seal was analyzed. Every problem and handing method of dry gas seal existed in the process of gas compressor operation of 800Kt/a heavy oil catalytic cracking unit were recommended in detail. It was recognized that the most advanced seal technology could give full play to its advantage, and secure the long period operation of whole set, only when it was organically in combination with the feeding system of cushion gas in unit |
