제1,2,3,4도는 본 발명의 2단계 투과기를 가지는 암모니아 합성플렌트의 공정도.1, 2, 3, and 4 are process diagrams of ammonia synthesis plant having a two-stage permeator of the present invention.

제5도는 본 발명에서 사용하는 유공섬유 격막 투과기의 단면도.Figure 5 is a cross-sectional view of the porous fiber diaphragm permeator used in the present invention.

Claims (1)

연속인 최소한 2단계의 투과기에서 각 단계의 투과기는 기상원료 혼합물내의 적어도 하나의 다른 가스의 투과율과 비교하여 적어도 하나의 가스의 투과성에 선택성을 나타내는 분리 격막과 공급변과 투과물 배출변으로 구성되며 투과물 배출변은 공급변의전압보다 낮은 전압에 있으며 또한 투과기단계 사이에는 한 투과기단계의 공급변으로 부터의 비투과가스는 적어도 하나의 투과기단계가 적어도 하나의 연속의 투과기단계의 투과물 배출변상의 전압에 대한 공급변의 전압비보다 투과물배출변상의 전압에 대한 공급변상의 낮은 전압비를 가지는 것을 특징으로는 다음 단계 투과기의 공급변으로 통과하며 상기 적어도 하나의 연속단계 투과기의 상기 투과물 배출변상의 전압은 상기 적어도 한단계의 투과기의 상기 투과물배출변상의 전압보다 낮은 직열로된 적어도 2단계 투과기에 기상원료 혼합물을 통과시킴으로서 이루어지는 적어도 하나의 다른 가스를 함유하는 기상 원료 혼합물로부터 적어도 하나의 가스 분리공정.In a continuous permeator of at least two stages, the permeator of each stage is composed of a separation diaphragm that exhibits selectivity for the permeability of at least one gas compared to the permeability of at least one other gas in the gaseous raw material mixture, a supply side and a permeate discharge side. The permeate discharge side is at a voltage lower than that of the supply side, and between the permeator stages, the non-permeable gas from the supply side of one permeator stage is transmitted through at least one permeator stage. It has a lower voltage ratio of the supply side to the voltage of the permeate discharge side than the voltage ratio of the supply side to the voltage of the water discharge side, which passes through the supply side of the next-stage permeator, The voltage of the permeate discharge compensation phase is from a gaseous raw material mixture containing at least one other gas, which is formed by passing a gaseous material mixture through at least two-stage permeator in direct heat lower than the voltage of the permeate emission compensation phase of the at least one stage permeator. At least one gas separation process. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed according to the contents of the initial application.
