Patent ID: 8632686

Claim:
An apparatus to remove water content in an organic solvent, the apparatus comprising: a treatment tank to which the organic solvent is introduced, a solvent inlet section of the treatment tank that introduces the organic solvent to the treatment tank, a solvent outlet section of the treatment tank through which a treated organic solvent is discharged from the treatment tank, an inert gas inlet section of the treatment tank from which inert gas is introduced to the treatment tank, a treatment gas outlet section of the treatment tank from which treatment gas is discharged from the treatment tank, a cooling treatment tank in which the treatment gas is cooled and gas and liquid are separated, a treatment gas inlet section of the cooling treatment tank connected to the treatment gas outlet section through which the treatment gas is introduced to said cooling treatment tank, a recovered liquid outlet section of the cooling treatment tank from which a separated liquid organic solvent is discharged from the cooling treatment tank, a waste gas outlet section of the cooling treatment tank from which a separated gas is discharged from the cooling treatment tank, and multiple gas jetting ports at the tip of the inert gas inlet section, the multiple gas jetting ports capable of spraying gas in multiple directions and distributing the inert gas to an entire liquid surface of the organic solvent, wherein the water content in the organic solvent is removed by having the inert gas flow over an entire liquid surface of the organic solvent inside the treatment tank.
