Abstract

EN LA MAYORIA DE LOS EMPLEOS PRACTICOS DE LOS PROCEDIMIENTOS PARA BORDAR EL GAS DE ESCAPE SE MEZCLA AMINIACO A LA CORRIENTE DE GAS DE ESCAPA BARDADO CONTIENE TODAVIA RESIDUOS DE AMONIACO EN FORMA DE GAS. ADEMAS EL POLVO SUSPENDIDO CONDUCIDO, CONTIENE, LA MAYORIA DE LAS VECES, UNIONES FIJAS DE AMONIUM, QUE A TRVES DE LA REACCION DEL AMONIACO SE PRODUCE CON COMPONENTES ACIDOS DEL GAS DE ESCAPE. COMO ES CONOCIDO, EL AMONIACO, EN FORMA DE GAS, SE LAVA DEL GAS DE ESCAPE Y SE RECUPERARA. DE LA CENIZA VOLANTE SE RECUPERA TAMBIEN AMONIACO A TRAVES DE TRATAMIENTO TERMICO O DE EXTRACCION. EL AMONIACO RECUPERADO SE ACUMULA EN UNA DISOLUCION ACUOSA EN UNA RESERVA DE AGUA DE AMONIACO. EL AMONIACO EMPLEADO PARA BORDAR COMO DISOLUCION ACUOSA A LA CORRIENTE DE GAS DE ESCAPE.
