Method for extruding gelatinous material

Abstract

Abstract AQUEOUS POLYMER SOLUTIONS USEFUL AS FLOODING AGENTS IN THE RECOVERY OF PETROLEUM BY WATER FLOODING, AND IS ESPECIALLY ADAPTED FOR INSTALLATION AT THE SITE OF A WATER INJECTION WELL. A METHOD FOR PROCUCING PARTICULATED GELATINOUS SUBSTANCES, SUCH AS GELATINOUS POLYMERS, AND SOLUTIONS OF THESE MATERIALS IN WHICH THE GEL IS FORMED IN A REACTION CHAMBER EQUIPPED WITH A HYDRAULICALLY ACTUATED PISTON THE PERFORATE EXTRUSION HEAD AND THE GELATINOUS PROCUCT IS SUBSEQUENTLY EXTRUDED INTO A STREAM OF SOLVENT OR NONSOLVENT LIQUID FLOWING AT RELATIVELY HIGH VELOCITY ON THE EXTERIOR OF THE PERFORATE HEAD. THE GELATINOUS SUBSTANCE IS DISPLACED FROM THE REACTION CHAMBER BY INTRODUCING A FLUID INTO THE REACTION CHAMBER ABOVE THE PISTON AT A SUFFCIENTLY ELEVATED PRESSURE TO DISPLACE THE SUBSTANCE FROM THE CHAMBER THROUGH THE PERFORATE EXTRUSION HEAD. THE HYDRAULIC PRESSURE ACTUATING THE PISTON IS ADJUSTED TO MAINTAIN THE PISTON IN PRESSURE BALANCE DURING THE EXTRUSION OPERATION. GRAVITATIONAL FORCES ACTING UPON THE PISTON CAUSE IT TO REST UPON THE UPPER SURFACE OF THE GELATINOUS MASS AND TO ADVANCE DOWNWARDLY THROUGH THE REACTOR AS THE GEL IS DISPLACED FROM THE CAHMBER. THE METHOD OF THIS INVENTION IS PARTICULARY SUITED FOR THE PREPARATION OF
