Abstract: The present invention relates to a process for thermal cracking of heavy petroleum oil, in which when a thermal cracking facility having a cracking furnace, two or more of trains each comprising two reaction vessels and one distillation tower is operated, each train is operated by repeating a cycle comprising drawing the heavy petroleum oil from the cracking furnace, feeding the drawn heavy petroleum oil into the first reaction vessel and then feeding the drawn heavy petroleum oil into the second reaction vessel, steam is directly brought in contact with the heavy petroleum oil to be thermally cracked, and gaseous cracked substances produced and steam are introduced into the distillation tower to be distilled and separated, wherein phase delay is provided for the cycle repeated in each train so that the thermal cracking facility is operated with the different initiation time of feeding to the first reaction vessel in each train.

Abstract: The suppression of coke adherence in a reaction vessel and cracked gas pipelines at the outlet of the reaction vessel and the prevention of plugging are designed by improving the dispersion of superheated steam inside the reaction vessel to preferable conditions, and pitch having more uniform and higher quality can be produced. A cracking process in which superheated steam is directly contacted with the heavy petroleum oil by blowing the superheated steam into the reaction vessel to be thermally cracked to oil fractions and pitch, wherein the superheated steam is blown into the reaction vessel from the bottom portion thereof so that the superheated steam generates rotational flow around the central axis of the shell of the reaction vessel.

Abstract: A substrate processing apparatus comprises a control unit executing a first recipe for substrate processing. After the substrate processing is completed through the execution of the first recipe, if a predetermined time is elapsed in a state that a next substrate to be processed is not carried into the process chamber, a second recipe is executed for maintaining a process chamber where the substrate is processed.
