Abstract
SE PRESENTA UN PROCESO PARA SU USO EN TUBERIAS DE GAS EN EL QUE EL LIQUIDO CONDENSADO ES EXTRAIDO HACIENDO PASAR UN CILINDRO (1) HECHO DE UN MATERIAL POLIMERICO ESPONJOSO, PROPULSADO POR UNA PEQUEÑA DIFERENCIA DE PRESION ENTRE LA PARTE TRASERA DEL CILINDRO ANTES MENCIONADO Y SU PARTE FRONTAL, DE MANERA QUE EL DESPLAZAMIENTO DEL CILINDRO A LO LARGO DE LA SUPERFICIE INTERNA DE LA TUBERIA EMPUJE EL LIQUIDO CONDENSADO. EL PISTON ESTA HECHO DE UN MATERIAL ESPONJOSO, PREFERIBLEMENTE POLIURETANO ESPONJOSO FLEXIBLE CON UNA DENSIDAD INFERIOR A 40 KM/M3 QUE SUFRE UNA PERDIDA DIMENSIONAL MAXIMA DEL 0.50% DESPUES DE ATRAVESAR LAS TUBERIAS CON UNA LONGITUD TOTAL DE MAS DE 1000 KM.
