摘要:
Provided is a method for providing a recommended operating condition with which an oil refinery device can be operated more efficiently. A server 20: acquires past operational data for a device, a scheduled operating condition which is an operation condition for the device scheduled by a user, and plant information including at least a usage expiry time of the device; creates a user-specific catalyst deterioration function from the past operational data; calculates, on the basis of the catalyst deterioration function, the plant information, and the schedule operating condition, a recommended operating condition that achieves a catalyst lifetime which is later than the usage expiry time of the device and is earlier than the catalyst lifetime when the device is operated under a scheduled operating condition calculated on the basis of the scheduled operating condition and the catalyst deterioration function; and transmits the recommended operating condition to a user terminal.

Provided are a desulfurization catalyst performance prediction system and a desulfurization catalyst performance prediction program with which the performance of a desulfurization catalyst is predicted with high accuracy, without performing a complicated process such as a plant simulation. A server, which is connected to a user terminal via a network, and which supplies a desulfurization catalyst lifetime of a user plant to a user on the basis of desulfurization catalyst bench plant data and a desulfurization catalyst lifetime function, is equipped with a processor and a storage means that stores computer-readable command. When a computer-readable command is executed by the processor, the server receives user plant-related data and a user desulfurization catalyst performance prediction condition from the user terminal to the user plant on the basis of a comparison between the desulfurization catalyst bench plant data and the obtained user plant-related data, calculates a catalyst lifetime for the user's desulfurization catalyst on the basis of the obtained user desulfurization catalyst performance prediction condition and the user desulfurization catalyst lifetime function, and transmits the calculated catalyst lifetime to the user terminal.

In the hydrocarbon-producing apparatus of the present invention, 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 is provided with a first return line. The vapor-liquid separation tank of the second vapor-liquid separation unit is provided with 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.
摘要:
A start-up method for a hydrocarbon synthesis reaction apparatus, comprising: an initial slurry-loading step in which the slurry is loaded into the reactor at the initial stage of the Fischer-Tropsch synthesis reaction at a lower loading rate than that applied to the reactor in a steady-state operation; and a CO conversion ratio-increasing step in which the liquid level of the slurry in the reactor is raised by adding to the slurry the hydrocarbons synthesized at the early stage of the Fischer-Tropsch synthesis reaction so that the CO conversion ratio is increased in proportion to a rise in the liquid level of the slurry in the reactor.
摘要:
Heavy hydrocarbons contained in FT off gas of a GTL process are removed by bringing the FT off gas into contact with absorption oil, by introducing the FT off gas into a distillation tower, by cooling the FT off gas or by driving the FT off gas into an adsorbent. A burner tip for heating a reformer tube, using FT off gas as fuel, is prevented from being plugged by the deposition of heavy hydrocarbons contained in the FT off gas.
