Patent
Cosmo Oil Co. and Kubota Co. | Date: 2015-03-09

A separation preventing device that prevents separation of a fluid pipe in a pipe axis direction, includes a main body externally fitted to an outer peripheral surface of the fluid pipe and has a recess portion facing the outer peripheral surface; a locking member housed in the recess portion in a tiltable manner and is able to bite into the outer peripheral surface of the fluid pipe; and pressing units that are provided in the main body and press the locking member, wherein the locking member has a plurality of wedge portions in a front-back direction of a pipe axis of the fluid pipe, and is equipped with a projection portion that regulates biting of a front wedge portion of the plurality of wedge portions into the fluid pipe, when the fluid pipe moves to a separation side in the pipe axis direction.

There is provided a method for upgrading hydrocarbon compounds, in which hydrocarbon compounds synthesized in a Fisher-Tropsch synthesis reaction are fractionally distillated, and the fractionally distillated hydrocarbon compounds are hydrotreated to produce liquid fuel products. The method includes fractionally distilling heavy hydrocarbon compounds synthesized in the Fisher-Tropsch synthesis reaction as a liquid into a first middle distillate and a wax fraction, and fractionally distilling light hydrocarbon compounds synthesized in the Fisher-Tropsch synthesis reaction as a gas into a second middle distillate and a light gas fraction.

In the hydrocarbon-producing apparatus, a vapor-liquid separation tank of a second vapor-liquid separation unit is provided with a filling material layer. A vapor-liquid separation tank of the first vapor-liquid separation unit has a first return line. The vapor-liquid separation tank of the second vapor-liquid separation unit has a second return line. A light component of light oil discharged from a bottom of the vapor-liquid separation tank is returned to a portion between a top side above a return-location from the second return line within the vapor-liquid separation tank of the second vapor-liquid separation unit, and a line directly connected with a cooler installed on the first vapor-liquid separation unit through the first return line. A heavy component of light oil discharged from a bottom of the vapor-liquid separation tank of the second vapor-liquid separation unit is returned to the filling material layer through the second return line.
