  • Patent number: 10915837
    Abstract: 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.

  • Publication number: 20190322950
    Abstract: A server is configured to be connected to a user terminal via a network, and to supply a desulfurization catalyst lifetime of a user plant to a user based on desulfurization catalyst pilot plant data and a desulfurization catalyst lifetime function. The server includes a processor and a memory storing computer-readable instructions. When the computer-readable instructions are 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 based on a comparison between the desulfurization catalyst pilot plant data and the obtained user plant-related data, calculates a catalyst lifetime for the user's desulfurization catalyst based on 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.
