我国大型空分设备的发展,从整体上看,大型空分的数量已经达到了世界上绝对多数,6万等级空分占全球空分的比例大于75%;国内单体规模已达10万等级,在近三年的市场需求中,特大型空分比例占绝大多数。近几年我国空分设备的建设特点如下:一是“大”配套机组的稳定性、运输条件限制、安装困难度大;二是“快”可调整时间短、管理有漏洞;三是“环境”化工区污染物严重、缺水、西北地区风沙大;四是安装队水平参差
As a whole, the number of large-scale air separation units has reached the absolute majority in the world. The proportion of 60,000 air space units accounted for more than 75% of the world air space units. The size of domestic single units has reached 100,000 In the past three years, the market demand, the vast majority of large-scale air separation. In recent years, China’s air separation plant construction features are as follows: First, “big ” supporting unit stability, transport constraints, the installation of a large degree of difficulty; Second, “fast” can be adjusted for a short time, management loopholes; Third, “Environment ” Chemical Industry Park, serious pollutants, water shortages, wind and sand in Northwest China; Fourth, the level of the installation team varies
