SOLID ELECTROLYTE SYSTEMS FOR USE WITH FURNACES

摘要

A PROCESS FOR OXYGEN-ENRICHING A FIRST FEED GAS STREAM (2) TO BE FED INTO A FURNACE (12) BY UTILIZING AN OXYGEN-ENRICHED GAS STREAM (44;71;120;146;187;214;306;330) FROM A SECOND FEED GAS STREAM (47;82;106;135;174;210;301;319), WHEREIN THE FIRST FEED GAS STREAM (2) IS COMPRESSED AND THEN HEATED (10) PRIOR TO INJECTION INTO THE FURNACE (12).THE SECOND FEED GAS STREAM (47;82;106;135;174;210;301;319) IS SEPARATED USING AN ION TRANSPORT MODULE (38;83;107;136;176;211;302;321) CONTAINING AN ION TRANSPORT MEMBRANE (40;84;108;138;178;212;304;322) HAVING A RETENTATESIDE (40A;84A;108A;138A;178A;212A;304A;322A) AND A PERMEATE SIDE (40B;84B;108B;138B;178B;212B;304B;322B) TO PRODUCE AN OXYGEN-DEPLETED GAS STREAM (48;86;110;140;180;216;312;340) ON THE RETENTATE SIDE (40A;84A;108A;138A; 178A;212A;304A;322A) AND THE PURE OXYGEN GAS STREAM OR THE OXYGEN-ENRICHED GAS STREAM (44; 71; 120; 146; 187; 214; 306; 330) ON THE PERMEATE SIDE (40B;84B;108B;138B; 178B;212B;304B;322B) THE PURE OXYGEN GAS STREAM OR THE OXYGEN-ENRICHED GAS STREAM (44;71;120;146;187;214;306;330)IS ADDED TO THE FIRST FEED GAS STREAM (2) AT ANY LOCATION BEFORE THE FIRST FEED GAS STREAM (2) ENTERS THE FURNACE (12) .(FIGURE 1)
