Abstract

COMPOSICIONES PARA EL TRATAMIENTO DE SISTEMAS AGUA-VAPOR, ESPECIALMENTE EN CALDERAS DE MEDIA Y ALTA PRESION. COMPRENDEN: AGENTE DESOXIGENANTE Y PASIVAMENTE DE SUPERFICIES METALICAS, TAL COMO LAS HIDROXILAMINAS; AGENTES ALCALINIZANTES TAL COMO ALCANOLAMINAS PARA FASE LIQUIDA Y AMINAS CICLICAS PARA FASE VAPOR. COMPRENDEN ADEMAS SOLUCIONES ACONDICIONADORAS-DISPERSANTES DE FANGOS PARA USO EN SISTEMAS DE MEDIA Y ALTA PRESION. COMPRENDEN CATALIZADOR QUE AUMENTA LA VELOCIDAD DE CAPTACION DEL OXIGENO. VENTAJOSAMENTE COMPRENDEN: DIETILHIDROXILAMINA COMO AGENTE DESOXIGENANTE, EN CONCENTRACIONES DEL 5 AL 26 POR CIENTO; TRIETANOLAMINA COMO ALCANOLAMINAS Y/O CICLOHEXILAMINA Y MORFOLINA COMO AMINAS CICLICAS, EN CONCENTRACIONES DEL 7 AL 40 POR CIENTO; COPOLIMEROS DE ACIDO ACRILICO/ACRILAMIDA Y SUS DERIVADOS COMO SOLUCIONES ACONDICIONADORAS-DISPERSANTES DE FANGOS, PRESENTES EN CONCENTRACIONES HASTA DEL 10 POR CIENTO; HIDROQUINONA COMO CATALIZADOR, EN CONCENTRACIONES DEL 0,1 AL 0,5 POR CIENTO. SE UTILIZAN EN SISTEMAS AGUA-VAPOR, PREFERENTEMENTE SISTEMAS DE CALDERAS A MEDIA Y ALTA PRESION.COMPOSITIONS FOR THE TREATMENT OF WATER-STEAM SYSTEMS, ESPECIALLY IN MEDIUM AND HIGH PRESSURE BOILERS. THEY INCLUDE: DEOXYGENATING AND PASSIVELY AGENT OF METALLIC SURFACES, SUCH AS HYDROXYLAMINES; ALKALINIZING AGENTS SUCH AS ALCANOLAMINES FOR LIQUID PHASE AND CYCLICAL AMINES FOR STEAM PHASE. FURTHER CONDITIONING SOLUTIONS-DISPERSANTS OF MUD FOR USE IN MEDIUM AND HIGH PRESSURE SYSTEMS. THEY INCLUDE A CATALYST THAT INCREASES THE OXYGEN CAPTATION RATE. ADVANTAGES INCLUDE: DIETILHIDROXILAMINA AS A DEOXYGENATING AGENT, IN CONCENTRATIONS FROM 5 TO 26 PERCENT; TRIETHANOLAMINE AS ALCANOLAMINS AND / OR CYCLLOHEXYLAMINE AND MORPHOLINE AS CYCLIC AMINES, IN CONCENTRATIONS OF 7 TO 40 PERCENT; ACRYLIC / ACRYLAMIDE ACID COPOLYMERS AND THEIR DERIVATIVES AS MUD DISPERSING CONDITIONING SOLUTIONS, PRESENT IN CONCENTRATIONS UP TO 10 PERCENT; HYDROQUINONE AS A CATALYST, IN CONCENTRATIONS OF 0.1 TO 0.5 PERCENT. THEY ARE USED IN WATER-STEAM SYSTEMS, PREFERABLY MEDIUM AND HIGH PRESSURE BOILER SYSTEMS.
