US Classification:

423089000, 423099000, 423111000, 423087000

Abstract:

Disclosed herein are methods for removing and recovering metalloids from gasification systems. Also disclosed are methods for on-line removal of deposited entrained materials from a heat exchanger unit. A method is provided for on-line removal and recovery of deposits from fossil fuel gasification systems to improve plant performance and recover a valuable metalloid. Plant performance will be improved by decreasing impedance to gas flow and decreasing downtime required to clean the gas cooling system by providing an effective method to remove deposits while the gasification system is operating. In the preferred embodiment of the method, the deposits rich in condensed metals and metalloids are captured on heat transfer surfaces within the range of temperatures of about 400 C. to about 600 C., the temperature of the heat transfer surface is cycled causing the deposit to spall from the steel surface, and the deposits are removed from the gasifier without impacting gasifier operation.

US Classification:

210766, 210151

Abstract:

A method and apparatus are provided for improving water quality using a gasification system. Whereas water is normally a deterrent to the combustion process, water is beneficial to the gasification of carbonaceous materials. The method and apparatus uses this, and other aspects, to utilize several processes to improve water quality by means of gasification in new and beneficial ways.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G07B 1502

US Classification:

235384

Abstract:

A radio frequency (RF) tagging system is used to monitor vehicles passing through an area access to one or more vehicle storage area(s). One or more of the vehicles stored in the storage area is equipped with a RF tag which has vehicle ID information about the vehicle stored in a tag memory contained on the tag. The tag communicates with a base station when passing through the area accesses, (entering or leaving). A central and preferably one or more remote computers accesses status information that might include vehicle identification, customer, lot identification, time of day, and vehicle and lot status. The information is used in security or marketing functions. The security function can include a paging system for sending alarms and/or messages to a manager or security personnel. The marketing function can include determining how long or how many times different makes an model of vehicle are chosen by customers for test drives. Additionally, the marketing function will identify past vehicles that were sold at the dealership as an indication of a potential interested buyer.

International Classification:

G01N 23/222
G01N 23/223
G01N 33/28

Abstract:

A system for predicting rare earth elements (REEs) in a feedstock sample includes a measurement instrument that records a measurement for a sample, a processor communicatively coupled to the measuring instrument, and a memory communicatively coupled to the processor and containing machine readable instructions that, when executed by the processor, cause the processor to correlate the measurement series using a model; and predict a presence of one or more rare earth element based at least in part on the correlation. A method for predicting rare earth elements includes measuring feedstock samples via XRF or PGNAA, to generate a measurements of elements of interest with a lower atomic weight than REEs; correlating the measurements with a model; and predicting a presence of one or more rare earth elements based at least in part on the correlation.

Abstract:

A method includes contacting a coal feedstock with an acidic solution to form residual coal and a leachate. The method further includes separating the residual coal from the leachate where the leachate contains rare earth elements and where the residual coal has preserved organic content and reduced inorganic content. Another method includes contacting a coal feedstock with a basic solution to form residual coal and a leachate. The method further includes separating the residual coal from the leachate where the leachate contains rare earth elements and where the residual coal has reduced inorganic content, but preserved organic content.
