  • A comparison study of absorption capability of several types of organic solvent: di(2-ethylhexyl) adipate (DEHA), polyethylene 400 (PEG400), polydimethyl siloxane (PDMS), vegetable oil, waste lubricant oil, 0# diesel was conducted using a self-designed absorption device. The results show that changing of the types of solvents or toluene concentration in the waste gases can obviously influence the toluene absorption capability. The toluene absorptive efficiency of the organic solvents will decrease with increasing absorption duration, up to a dynamic saturation. With increasing toluene concentration of the inlet gas, the effective absorption amount of an organic solvent to toluene will decrease, but its saturated absorption amount will increase. Under the same experimental conditions, DEHA shows the biggest toluene absorption capability, followed by vegetable oil, waste lubricant oil and 0# diesel, and PEG400 and PDMS are the worst absorption solvents to toluene. The present result provides a theoretical basis to select a high performance absorption liquid of toluene waste gases for engineering design.

Abstract: A comparison study of absorption capability of several types of organic solvent: di(2-ethylhexyl) adipate (DEHA), polyethylene 400 (PEG400), polydimethyl siloxane (PDMS), vegetable oil, waste lubricant oil, 0# diesel was conducted using a self-designed absorption device. The results show that changing of the types of solvents or toluene concentration in the waste gases can obviously influence the toluene absorption capability. The toluene absorptive efficiency of the organic solvents will decrease with increasing absorption duration, up to a dynamic saturation. With increasing toluene concentration of the inlet gas, the effective absorption amount of an organic solvent to toluene will decrease, but its saturated absorption amount will increase. Under the same experimental conditions, DEHA shows the biggest toluene absorption capability, followed by vegetable oil, waste lubricant oil and 0# diesel, and PEG400 and PDMS are the worst absorption solvents to toluene. The present result provides a theoretical basis to select a high performance absorption liquid of toluene waste gases for engineering design.
