Download or read book Heat Pumps in Chemical Process Industry written by Anton A. Kiss and published by CRC Press. This book was released on 2016-10-14 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the chemical process industry is among the most energy demanding sectors, chemical engineers are endeavoring to contribute towards sustainable future. Due to the limitation of fossil fuels, the need for energy independence, as well as the environmental problem of the greenhouse gas effect, there is a large increasing interest in the research and development of chemical processes that require less capital investment and reduced operating costs and lead to high eco-efficiency. The use of heat pumps is a hot topic due to many advantages, such as low energy requirements as well as an increasing number of industrial applications. Therefore, in the current book, authors are focusing on use of heat pumps in the chemical industry, providing an overview of heat pump technology as applied in the chemical process industry, covering both theoretical and practical aspects: working principle, applied thermodynamics, theoretical background, numerical examples and case studies, as well as practical applications. The worked-out examples have been included to instruct students, engineers and process designers about how to design various heat pumps used in the industry. Reader friendly resources namely relevant equations, diagrams, figures and references that reflect the current and upcoming heat pump technologies, will be of great help to all readers from the chemical and petrochemical industry, biorefineries and other related areas.

This book was released on 1995 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: ON ETUDIE, SUR LE PLAN THEORIQUE ET EXPERIMENTAL, DES SYSTEMES THERMODYNAMIQUES A COMPRESSION-ABSORPTION DESTINES A LA PRODUCTION SIMULTANEE DE FROID ET DE CHALEUR. LE CYCLE HYBRIDE ELEMENTAIRE, AVEC LE MELANGE EAU-AMMONIAC, EST APPLICABLE AUX DOMAINES DES MACHINES FRIGORIFIQUES (-20C) ET DES POMPES A CHALEUR (JUSQU'A 100C). L'EFFICACITE DU CYCLE RESTE INFERIEURE DE 1 A 10% A L'EFFICACITE D'UN CYCLE A COMPRESSION D'AMMONIAC MAIS COMPARABLE AVEC CELLE DES CYCLES UTILISANT LES HCFC CLASSIQUES. NOUS INTRODUISONS ET DECRIVONS PLUS DE 60 CYCLES HYBRIDES COMPOSES AU PLUS DE SIX ELEMENTS PRINCIPAUX. NOTRE CHOIX DE L'APPLICATION, NOUS A CONDUIT A RETENIR SEULEMENT SIX CYCLES. LES PERFORMANCES SIMULEES APPARAISSENT DISPERSEES ET SANS RELATION AVEC LE NOMBRE DE CONSTITUANTS. ELLES SONT INFERIEURES DE 13% ENVIRON A LA PERFORMANCE D'UN CYCLE A AMMONIAC PUR A DEUX ETAGES (A INJECTION TOTALE). LE BANC D'ESSAIS SE COMPOSE D'UN CYCLE A COMPRESSION D'AMMONIAC PUR COUPLE A UN CYCLE HYBRIDE ELEMENTAIRE. LES RESULTATS, SUR LE CIRCUIT HYBRIDE, DONNENT UN COEFFICIENT DE PERFORMANCE FRIGORIFIQUE COMPRIS ENTRE 3 ET 3,4 SELON LA COMPOSITION DU MELANGE (90 A 60%) POUR L'ECART DE TEMPERATURE 0/40C SUR LE FRIGORIGENE. LA PERFORMANCE MAXIMALE POUR LES TEMPERATURES 0/60C TOMBE A 2,12. LA PUISSANCE THERMIQUE VARIE DANS UN RAPPORT DE 1 A 4 LORSQUE LE TAUX DE RECIRCULATION VARIE. LE COUPLAGE DES DEUX CIRCUITS NE POSE PAS DE DIFFICULTE PARTICULIERE ET LE FONCTIONNEMENT EN THERMO-FRIGO-POMPE EST VALIDE POUR DES ECARTS DE TEMPERATURE DE 100 K DANS LE CYCLE. L'EFFICACITE DE L'ABSORBEUR EST SUPERIEURE A CELLE DU DESORBEUR QUI ATTEINT EN MOYENNE 0,75. L'INTERET DES ECHANGEURS A PLAQUES, CHOISIS POUR L'ABSORPTION ET LA DESORPTION, EST DEMONTRE BIEN QUE DES MODIFICATIONS DOIVENT ETRE APPORTEES POUR ETENDRE LEURS CONDITIONS DE FONCTIONNEMENT

ZANIFE and published by . This book was released on 1991 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: L'OBJET DE CE TRAVAIL CONCERNE LA GESTION DE LA CHALEUR DANS LES MACHINES A ADSORPTION A DEUX ADSORBEURS. NOUS AVONS CONSIDERE DEUX COUPLES, DEUX TYPES DE CYCLES ET DEUX TYPES DE MACHINES: 1) LES DEUX COUPLES CONSIDERES SONT LES COUPLES ZEOLITHE-EAU D'UNE PART ET CHARBON ACTIF-METHANOL D'AUTRE PART; 2) LES DEUX CYCLES ETUDIES SONT LE CYCLE A RECUPERATION DE CHALEUR ET LE CYCLE A RECUPERATION DE MASSE; 3) LES DEUX TYPES DE MACHINES SONT D'UNE PART UN PILOTE DE POMPE A CHALEUR (PAC) DE 230 KW INSTALLE EN SITE INDUSTRIEL ET D'AUTRE PART UNE MAQUETTE DE MACHINE FRIGORIFIQUE. LES OBJECTIFS POURSUIVIS PAR LES ETUDES DES DEUX TYPES DE MACHINE SONT TRES DIFFERENTS. DANS LE CAS DE LA PAC, NOUS ABORDONS ESSENTIELLEMENT LES PROBLEMES LIES A LA REGULATION ET A L'INSERTION DANS LE RESEAU INDUSTRIEL DE LA DISTRIBUTION D'EAU CHAUDE SANITAIRE (ECS). NOUS METTONS EN EVIDENCE TROIS PARAMETRES DETERMINANT POUR LA COMMANDE DE LA PAC ZEOLITHE-EAU: LE DEBIT D'ALIMENTATION, LA CONSIGNE D'ARRET DE LA PHASE DE COMPLEMENT DE CHAUFFAGE/REFROIDISSEMENT (TZMAX ET TZMIN) ET ENFIN LA CONSIGNE D'ARRET DE LA PHASE DE RECUPERATION DE CHALEUR ENTRE LES DEUX ADSORBEURS (DT). L'ETUDE EXPERIMENTALE A PORTE SUR UNE PAC DE 230 KW. NOUS MONTRONS QUE L'UTILISATION D'UN SYSTEME MONOBLOC (ADSORBEUR RELIE DIRECTEMENT A L'EVAPO-CONDENSEUR) PRESENTE L'INTERET DE SIMPLIFIER LA COMMANDE ET DE REDUIRE CONSIDERABLEMENT LES RISQUES DE FUITE. LES POSSIBILITES ET LES LIMITES DE L'UNITE SONT ANALYSEES. DANS LE CAS DE LA MACHINE FRIGORIFIQUE A ADSORPTION, NOUS AVONS EFFECTUE L'ETUDE EXPERIMENTALE ET LA MODELISATION D'UN CYCLE OU INTERVIENT UN TRANSFERT DE FLUIDE FRIGORIGENE ENTRE LES DEUX ADSORBEURS. NOUS MONTRONS QUE L'UTILISATION D'UN TEL CYCLE PERMET DE BAISSER LA TEMPERATURE DE REGENERATION. IL EST ALORS POSSIBLE DE GENERER DU FROID A BASSE TEMPERATURE (10C) EN UTILISANT DES REJETS THERMIQUES A 80-90C POUR REGENERER LE CHARBON ACTIF
