Abstract
PROCESSO DE PRODUçãO DE ETENO A PARTIR DE áLCOOL ETìLICO. A presente invenção se refere ao processo de obtenção de eteno por desidratação do álcool etílico (etanol), mais precisamente a partir de etanol contido no álcool hidratado (AEHC) ou álcool anidro (AEAC) em presença de catalisador, em reator adiabático. é um dos objetivos da presente invenção, utilizar como fluido de aquecimento, uma quantidade determinada do efluente do reator, que consiste na mistura de eteno - vapor d'água e outros gerados na desidratação do etanol e de uma quantidade determinada de água, produzida pela condensação da água contida no efluente do reator. A água gerada no sistema de reação e a água proveniente da carga de AEHC/AEAC formam o efluente aquoso da unidade. Outros objetivos atingidos na presente invenção, com as modificações do sistema reacional e com a utilização dos fluidos de aquecimento, que são obtidas do próprio sistema reacional, são: 1) a maximização do aproveitamento do calor nas correntes de processo, com conseqüente redução no consumo de utilidades; 2) a redução do número de equipamentos, que permite a redução do pessoal de operação e do investimento e, em conseqüência, a redução dos custos de capital e de manutenção da unidade. A corrente enviada para a seção de separação, onde o eteno é o principal produto, é constituída pela mistura de eteno, vapor d'água, etanol não convertido, que será reciclado à extinção, e outros produtos gerados a partir de contaminantes eventualmente presentes no AEHC/AEAC, e que serão recuperados para outros usos.ETHENE PRODUCTION PROCESS FROM ETHICAL ALCOHOL. The present invention relates to the process of obtaining ethylene by dehydration of ethyl alcohol (ethanol), more precisely from ethanol contained in hydrated alcohol (AEHC) or anhydrous alcohol (AEAC) in the presence of catalyst, in an adiabatic reactor. It is an object of the present invention to use as a heating fluid a determined amount of reactor effluent consisting of a mixture of ethylene - water vapor and others generated in the dehydration of ethanol and a certain amount of water produced by the reactor. condensation of water contained in the reactor effluent. Water generated in the reaction system and water from the AEHC / AEAC charge form the unit's aqueous effluent. Other objectives achieved in the present invention, with the modifications of the reaction system and the use of heating fluids, which are obtained from the reaction system itself, are: 1) the maximization of the heat utilization in the process streams, with consequent reduction in the consumption of utilities; 2) the reduction in the number of equipment, which allows the reduction of operating and investment personnel and, as a result, the reduction of unit capital and maintenance costs. The current sent to the separation section, where ethylene is the main product, consists of a mixture of ethylene, water vapor, unconverted ethanol, which will be recycled to extinction, and other products generated from contaminants eventually present in the product. AEHC / AEAC, which will be recovered for other uses.
