  • Patent number: 11135545
    Abstract: Provided is a gas separation device configured to separate a non-hydrocarbon gas from a feed gas containing the non-hydrocarbon gas through use of a gas separation membrane, in which a decrease in operating rate can be suppressed, and economic efficiency is satisfactory. A first membrane module (1) and a second membrane module (2) are arranged in parallel to each other with respect to supply lines for a feed gas. Gas lines for regeneration (14, 15) ((24, 25)), which are branched from a permeate gas line (13) ((23)) of the membrane module (1) ((2)), and which are joined to a feed gas line (21) ((11)) configured to supply the feed gas to the membrane module (2) ((1)), are provided. Under a state in which the feed gas is supplied to the membrane module (1), a permeate gas through the membrane module (1) is supplied, as a gas for regeneration, to the membrane module (2) through the gas lines for regeneration (14, 15).

  • Patent number: 9146793
    Abstract: A management system outputs catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of multiple providable resources, and which shows the respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources. The management system provides the selected resource as a provided resource, and determines, based on a performance threshold configured with respect to the application of the provided resource, whether or not a performance measurement value, which relates to the processing performance of a network service using the provided resource and which can be monitored by the management system, is normal.

  • Patent number: 8051262
    Abstract: A storage system stores golden image of a server or any physical/virtual machine execution environment and associate the golden image and the storage port. The storage system also creates the copy of the golden image to the logical volume, and allocates the internal path between the storage port and the logical volume. Upon receiving an access request from the host computer via the storage port, the storage system transfers the access request between the storage port and the logical volume which stores the copy of golden image associated with the host computer.
