摘要

利用全生命周期成本理论（LCC）方法，对新型泡沫碳化硅陶瓷波纹规整填料（SCFP-SiC）和传统的金属波纹板规整填料（SCMP）从原材料采购、填料生产以及使用的整个生命周期进行经济评价比较。结果表明，SCFP-SiC填料的生产成本相比SCMP填料的生产成本偏高，但SCFP-SiC填料生产成本受原材料价格波动影响较小；在使用阶段，无论是降低塔高从而降低固定成本方面，还是降低回流比从而降低可变成本方面，SCFP-SiC填料均具有总成本优势。另外综合新型SCFP-SiC填料所具有的超强耐腐蚀性能，未来使用新型泡沫碳化硅陶瓷波纹规整填料替代传统金属波纹板规整填料具有明显的经济性优势。

Abstract

Structured packing has been widely used in distillation processes. An economic feasibility analysis of a new structured packing

the structured corrugation SiC-foam packing (SCFP-SiC)

was compared to traditional structured corrugation metal packing (SCMP) in the whole life cycle from raw materials

production to end use by life cycle cost (LCC) theory. Results showed that the production cost of SCFP-SiC was higher than that of SCMP but was less affected by price fluctuation of raw materials. In end use

SCFP-SiC could have overall cost saving advantages by whether decreasing the tower height to reduce the fixed cost or decreasing the reflux ratio to reduce the variable cost. Assuming that SCFP-SiC could increase 1.5 times more theoretical plate number

the total cost would be lower for SCFP-SiC than SCMP in only 6.8 months' separation operation of xylene mixture. Considered its remarkable corrosion resistance

SCFP-SiC could significantly benefit end users from economic viewpoint as a SCMP replacement in separation processes.
