ADL公司发展部自1977年开始对液态CO_2-煤浆的管道输送进行研究,并已于去年六月与Grace公司签订投产合同。ADL公司的赛氏(C.J.Santhanom)认为液态CO_2-煤浆的管道输送显著优于常规的水基煤浆之处是:1.它的粘度很低,大大减少了泵送所需马力;2.煤浆中煤的重量含量可高达70～80%,而水煤浆中典型的煤的重量只是50%。这就意味着输送同样数量的煤,CO_2-煤浆系统的管网要比水-煤浆的小得多。因此CO_2-煤浆系统的投资及操作费用要比铁路或水-煤浆运输至少要少30～50%(见表)。3.CO_2-煤浆更易分离,
Since 1977, ADL Development has studied the pipeline transportation of liquid CO_2-coal slurry and signed a production contract with Grace in June last year. ADL’s CJ Santhanom believes that the pipeline liquid CO2 coal slurry is significantly superior to the conventional water-based coal slurry is: 1. Its viscosity is very low, greatly reducing the pump horsepower required; The weight content of coal in coal slurry can be as high as 70-80%, while the weight of typical coal in coal water slurry is only 50%. This means that for the same amount of coal to be delivered, the CO_2-coal slurry system has a much smaller network than water-coal slurry. As a result, the investment and operating costs for the CO_2-coal slurry system will be at least 30-50% less than for railways or water-coal slurry transport (see table). 3.CO_2-coal slurry easier to separate,
