The desulfurizers (cyclobutyl sulfone and diisopropanolamine) have poisonousness. If the sweetening solution foamed seriously that can't be used, sweetening solution's discharge will affect environment.

脱硫溶液严重发泡后将不能再使用，且脱硫溶剂环丁砜和二异丙醇胺都具有毒性，脱硫溶液的排放将会对环境安全造成严重地影响。

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.

Therefore, in the laboratory, a 2L gasliquid equilibrium measurement device was used to measure the equilibrium solubility of H2S, CO2, CH3SH and COS in the mixed solutions of Methyldiethanolamine, Tetramethylene sulfone respectively under different temperatures and different proportions. With the relevant parameters being correlated from the measured data, a corresponding thermodynamic calculation model was set up, based on the gasliquid two phase state equilibrium equation, and in combination with the overseas research results.
