There was a rush of interest in CCS in the late 2000s, including $3 billion for it in America sstimulus package of 2009. But many projects are now being cancelled. Either the developershave lost confidence in government commitments to support them or their costs haveturned out higher than expected. Mongstad-a billion-dollar development owned jointly by theNorwegian government and three oil companies, Statoil, Shell and Sasol of South Africa-is arare exception that has actually opened. Hence the hoopla.
二十世纪末,有一阵子人们对CCS感兴趣,2009年美国曾对其直接投入三十亿美元。但是很多工程现在被取消了。不是支持工程的开发商对政府的承诺失去信心就是成本超出预期。蒙斯塔出人意料地联合挪威政府和三家石油公司开发的价值十亿美元的项目已经正式开工。关于CCS的争论更加激烈。
The facility itself consists of two capture plants fitted with more than 4,000 instruments tomonitor what is going on, and with a total capacity of 80,000 tonnes of carbon a year. Theseplants are connected to the exhaust flues of the refinery and also to a nearby gas-firedpower station. That lets operators experiment with different flow rates and carbon-dioxideconcentrations, which can be tweaked to be anything from 3.5% to 14% .
这个装置本身包括装配着两个收集设备,这两个设备里面安置了四千个用来监控设备运行的仪表,每年能收集八万吨碳。这些设备和炼油厂的废气管相连,而且附近就是一座燃烧天然气的发电站。操作人员可以用不同的流速和二氧化碳浓度进行试验,这些参数可以从3-5%调整到14%。
