Title: Production of coal needle coke
Inventor: TSUYUKUCHI AKIO
IPC: C10B57/04
Filed: 1980-03-28
Abstract: PURPOSE: To obtain needle coke of good quality in high coke yields, by a method wherein refined tar is coked while blowing a gas inert to coke into a coke drum from the bottom of said drum.  
     CONSTITUTION: Coal tar is distilled to remove a light fraction and to obtain a heavy fraction. Quinoline-insoluble matter is removed from said heavy fraction to obtain refined tar. Alternatively, said heavy fraction is distilled under reduced pressure to obtain further a heavy fraction from which guinoline-insoluble matter is then removed to obtain refined tar. In a process for coking the above refined tar by a delayed coking process, a gas inert to coke is blown into a coke drum from the bottom thereof. The amount of the gas is adjusted so as to give a gas superficial velocity in the drum of 1W10cm/sec. (calculated from temperature, pressure and MW). It is presumed that spherulites generated by heating the refined tar at 400W500°C have a considerably high viscosity at the combining period of crystals. But, when the gas is blown into the drum at the above gas superficial velocity in the drum, a shearing force having a directional property acts on the spherulites during the passing of bubbles through the spherulites to promote the formation of needle coke. It is believed that the above gas superficial velocity in the drum functions as stated above.

Title: Evaporation of liquefied natural gas
Inventor: EBARA KATSUYA
IPC: F17C9/02
Filed: 1979-04-06
Abstract: PURPOSE:To avoid freezing in liquefied natural gas and stabilize its evaporation, by directly heating the plain water used for heating and evaporating liquefied natural gas with part of the exhaust gas of the natural gas combustion and extracting the plain water by its increased volume by heating to control the plain water temperature. CONSTITUTION:After the heating medium is heated by the heater 40, it enters the evaporator 31 through the duct 35, and there it heats and evaporates LNG, then it is returned to the heater 41 through the duct 36. The liquefied LNG goes through the duct 33 to the boiler 34 where it is combusted, and the combustion exhaust gas is discharged from the outlet 42. From the duct 37 through which the combustion exhaust gas flows a duct 38 is branched to send part of the exhaust gas into the heater 40 and to heat the heating medium. During this, increase of volume of plain water corresponding to the exhaust gas moisture condensed in the circulating plain water is discharged through the duct 43. Circulating and heating of the heating medium in this way keeps the temperature at the outlet of the evaporator over a constant temperature and prevents freezing of LNG in the evaporator, giving less trouble of corrosion and stable LNG evaporation.
