The processes for liquefied natural gas separation,including conventional distillation,thermally coupled distillation,side-stripper,double-effect distillation and heat-integrated distillation were simulated by using rigorous models and their energy consumptions were compared.

The wavelet and profile extraction-based algorithm were introduced to the field of chromatogram baseline extraction.
