Abstract
RECUPERACION DE HIDROCARBUROS CONDENSABLES DE UNA MEZCLA GASEOSA QUE LOS CONTIENE, PARTICULARMENTE ETANO, PROPANO Y SUPERIORES.SE UTILIZAN TURBINAS DE EXPANSION PARA OBTENER LAS BAJAS TEMPERATURAS NECESARIAS PARA LA CONDENSACION DE LOS GASES Y EL SUCESIVO FRACCIONAMIENTO DE LOS CONDENSADOS. LA PARTICULAR DISPOSICION DE LOS APARATOS Y DEL ESQUEMA DE FLUJO PROPORCIONA EFICIENTES RECUPERACIONES TERMICAS Y UN FRACCIONAMIENTO EFICAZ, PERMITIENDO CONSEGUIR ELEVADAS TASAS DE RECUPERACION DE HIDROCARBUROS CONDENSABLES CON UN MINIMO CONSUMO DE ENERGIA.
