Abstract:
본 발명은 분리막 모듈 및 이를 포함하는 불화가스 분리장치에 관한 것으로, 상세하게는 투과구 및 배출구를 포함하는 중공사막(hollow fiber membrane) 분리막 모듈에 있어서, 다공성 격막을 내부에 포함하여 상기 격막에 의해 분리막 모듈 내부가 복수개의 구획으로 구분되되, 구분된 복수개의 구획들은 격막의 기공에 의해 동일한 압력을 나타내고, 상기 다공성 격막의 기공으로부터 나온 투과기체가 모듈의 투과구를 통하여 배출되도록 구성된 것을 특징으로 하는 분리막 모듈을 제공한다. 본 발명에 따른 분리막 모듈 및 이를 포함하는 불화가스 분리장치는 감압에 의해 분리가 수행될 기체를 분리막 모듈로 유입시키는 경우, 분리막 모듈 내부의 압력을 고르게 유지하여 분리막 모듈 내부에서 발생할 수 있는 압력차이를 최소화할 수 있다. 이에 따라, 감압에 의해 불화가스를 분리 시 높은 효율로 불화가스를 분리할 수 있다.

CONSTITUTION: The manufacturing method of the acetylation methylcellulose includes the step of manufacturing solution by dissolving methylcellulose in the solvent containing more than one kind selected from the pyridine, and the acetone and their mixture, adding acetic anhydride in the solution and performing acetylation reaction and solidifying in the water. The rate of solvent and methylcellulose is 5 ~ 40 : 95 ~ 60 weight ratio. The amount of the acetic anhydride is 0.5 ~ 3 molar ratio per the methylcellulose unit. The acetylation reaction operates in 10 ~ 90°C. The acetylation methylcellulose has 160 ~ 180°C melting point.

PURPOSE: A palladium alloy composite membrane for separating hydrogen gas and a method for manufacturing the same are provided to preserve thermal and chemical stabilities between a metal of palladium alloy layer and a metal on a base, and obtain superior permeability coefficient and resolving power of hydrogen gas by introducing a silica thin film by a sol-gel method between the base and the palladium alloy membrane before introducing the palladium alloy membrane by vacuum-electrical plating to the upper part of a porous metallic base reformed with nickel particulate. CONSTITUTION: In a composite membrane for separating hydrogen gas in which a palladium alloy plating layer is introduced to the upper part of a porous metallic base, the palladium alloy composite membrane for separating hydrogen gas comprises a silica thin film layer which is formed between the porous metallic base and the palladium alloy plating layer. The method for manufacturing the palladium alloy composite membrane for separating hydrogen gas comprises the processes of reforming the surface of the base in which the surface of the porous metallic base is dispersion coated with nickel fine powder and heat treated; forming a silica thin film layer by coating silica sol precursor manufactured by hydrolyzing tetraethylorthosilicate (TEOS) on the reformed porous metallic base; and forming a palladium alloy plating layer on the other side of the base as applying a reduced pressure on one side of the silica thin film layer formed base to a pressure of 700 torr or less.
