Method and apparatus for storing normally gaseous hazardous material in liquid phase
Abstract
Abstract METHOD AND APPARATUS FOR SAFE VENTING OF VAPORS OF NORMALLY GASEOUS HAZARDOUS MATERIAL STORED IN LIQUID PHASE IN AN INSULATED CONTAINER UNDER LOW PRESSURE AND TEMPERATURE. HAZARDOAUS VAPOR IS WITHDRAWN FROM THE CONTAINER AT TIMES WHEN THE INTERNAL CONTAINER PRESSURE EXCEEDS A PREDETERMINED VALUE AND FED TO A ZONE CONTAINING A CATALYST TO OXIDIZE THE VAPOR TO A HARMLESS GAS WHICH IS VENTED TO THE ATMOSPHERE. IN THE EVENT THE CONTAINER INSULATION FAILS CAUSING RAPID VAPORIZATION OF STORED LIQUID, A LARGE QUANTITY OF HAZARDOUS VAPOR IS WITHDRAWN WHEN THE INTERNAL CONTAINER PRESSURE EXCEEDS A HIGHER PREDETERMINED VALUE AND FED TO A CATALYTIC ZONE OF GREATER CAPACITY WHICH MAY INCLUDE A PLURALITY OF CATALYTIC UNITS. THE INVENTION IS DISCLOSED IN THE ENVIRONMENT OF LIQUEFIED CARBON MONOXIDE AND HAZARDOUS VAPORS THEREOF BEING OXIDIZED CATALYTICALLY TO HARMLESS CARBON DIOXIDE.
