一、概述 随着我国石油化学工业的迅速发展,特别是近几年来,我国相继建成了一批大型化肥和石油化工装置。在这些装置中,都广泛采用了透平压缩机,并且结合化工工艺过程中的余热,充分地加以利用,以付产的大量蒸汽,采用蒸汽透平来来驱动它。 由于大容量、大功率的高速透平压缩机,是 First, an overview With the rapid development of China’s petrochemical industry, especially in recent years, China has built a number of large-scale fertilizer and petrochemical plants. In these installations, the turbine compressor is widely used and fully utilized with the residual heat of the chemical process, using a large amount of steam to pay for the production, using a steam turbine to drive it. Because of the large capacity, high-power high-speed turbine compressor, yes
