BOF drop-in thermocouple

Abstract: A BOF drop-in sensor assembly includes a handle, a weight, a sensor, and a cage to protect the sensor. The weight includes a high density material having a density of at least 1.2 times the density of steel. The cage comprises crossed rods which are easily melted and which allow molten steel to quickly envelop the sensor providing a highly reliable and accurate reading.

Process for producing one- and two-ring aromatics from polynuclear aromatic feedstocks

Abstract: In a process for upgrading a topped-tar fraction of coal tar, topped-tar feedstock containing largely polynuclear aromatic hydrocarbons is hydrocracked in a hydrogen atmosphere in a first reaction zone at a temperature and pressure sufficient to hydrocrack the large molecules to three- and two-ring aromaticnaphthenes. The hydrocracked feed which also contains olefins, is catalytically hydrotreated in a second reaction zone to saturate the olefins, and the feed is then catalytically treated in a third reaction zone at a temperature, pressure and hydrogen to hydrocarbon feed mol ratio sufficient to hydrocrack the threeand two-ring compounds to two- and one-ring aromatics, while, at the same time, naphthenes are dehydrogenated to aromatics, the alkyl aromatics are hydrodealkylated to nonsubstituted aromatic compounds, and substantially all oxygen, nitrogen and sulfur compounds unreacted in the first and second treatment zones are hydrorefined.

Regeneration of alkanolamine absorbing solution in gas sweetening processes

Abstract: A catalytic amount of ammonia or ammonium compounds are utilized to prevent deterioration of alkanolamines employed in gas sweetening processes. The ammonia is added either to the sour gas or the absorbing solution and acts to suppress thiocyanate formation during absorption.

Injection mold with ultra sonic gating means

Abstract: A mold is provided with a pair of cavities interconnected by a runner to a common entry point. One of the cavities is gated whereby plastic may be injected into this cavity only by applying ultrasonic energy to the gate.
