Low sulphur fuel system utilizing coal char,and coproducts thereof

Abstract

Abstract IN ACCORDANCE WITH THE DISCLOSURE OF THE PRESENT INVENTION IN ONE EMBODIMENT, COAL IN GRANULAR FORM IS HEATED AND INTRODUCED UNDER PRESSURE INTO A COAL DEVOLATILIZER FORMING A REACTION CHAMBER FOR THE COAL AND FROM WHICH REACTION BY-PRODUCTS ARE SEPARATELY WITHDRAWN. PREHEATED OIL ISINTRODUCED UNDER PRESSURE INTO AN OIL FLUID COKER FORMING A REACTION CHAMBER FOR THE OIL, AND FROM WHICH OIL REACTION PRODUCTS ARE SEPARATELY WITHDRAWN. GRANULAR RESIDUE FROM THE COAL DEVOLATILIZER AND OIL FLUID COKER ARE INTRODUCED UNDER PRESSURE INTO A HEAT GENERATOR IN WHICH FURTHER REACTION TAKES PLACE, THERE BEING MEANS FOR EFFECTING AN INTERCHANGE OF MATERIAL BETWEEN THE COAL DEVOLATILIZER AND THE HEAT GENERATOR, AND BETWEEN THE OIL FLUID COKER AND THE GENERATOR. THE BY-PRODUCTS FROM THE OIL FLUID COKER AND FROM THE COAL DEVOLATILIZER ARE SEPARATELY PROCESSED, AND THE DESULPHURIZED FUEL COMPONENTS THEREOF ARE USED WITH THE CARBONACEOUS PRODUCT, WHICH IS A COMBINED COAL CHAR AND OIL FLUID COKE, PRODUCED BY THE SYSTEM, WHEREBY TO PROVIDE A LOW SULPHUR FUEL SYSTEM, AND ALSO ELEMENTAL SULPHUR AND OTHER USEFUL BY-PRODUCTS WHICH MAY BE SEPARATELY UTILIZED. THE USE OF THE OIL FLUID COKER IS OPTIONAL, AND IN ONE FORM OF THE INVENTION THE OIL FLUID COKER COKER VESSEL IS USED AS A FURTHER PROCESSING VESSEL FOR DESULPHURIZING THE COAL, INTO WHICH HYDROGEN ISINTRODUCED TO FURTHER THE DESULPHURIZATION PROCESS.
