Process For Heating Coal-Oil Slurries

US Patent:
44241089, Jan 3, 1984
Filed:
Jan 8, 1982
Appl. No.:
6/337301
Inventors:
Walter A. Braunlin - Spring TX
Alan Gorski - Lovington NM
Leo J. Jaehnig - New Orleans LA
Clifford J. Moskal - Oklahoma City OK
Joseph D. Naylor - Houston TX

Assignee:
The Pittsburg & Midway Coal Mining Co. - Englewood CO
International Classification:
C10G 100
US Classification:
208 8LE
Abstract:
Controlling gas to slurry volume ratio to achieve a gas holdup of about 0. 4 when heating a flowing coal-oil slurry and a hydrogen containing gas stream allows operation with virtually any coal to solvent ratio and permits operation with efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry will depend on numerous factors such as coal concentration, coal particle size distribution, composition of the solvent (including recycle slurries), and type of coal. Further system efficiency can be achieved by operating with multiple heating zones to provide a high heat flux when the apparent viscosity of the gas saturated slurry is highest. Operation with gas flow rates below the critical minimum results in system instability indicated by temperature excursions in the fluid and at the tube wall, by a rapid increase and then decrease in overall pressure drop with decreasing gas flow rate, and by increased temperature differences between the temperature of the bulk fluid and the tube wall. At the temperatures and pressures used in coal liquefaction preheaters the coal-oil slurry and hydrogen containing gas stream behaves essentially as a Newtonian fluid at shear rates in excess of 150 sec. sup. -1.
