Patent CA-2864478-A1 (CA)
Inventor: ECKERT NORBERT
IPC: C01D3/06
Filed: 2013-02-20
Abstract: In a nanofiltration system for removing sulfate impurity from an aqueous brine stream and for recovering the brine, introducing a dilution stream upstream of the feed stream inlet of a nanofiltration module in the system dilutes the feed stream. This increases the amount of brine salt and water obtained in the permeate stream without substantially diluting the concentration of sulfate in the pass stream and hence results in enhanced recovery of brine while efficiently removing sulfate impurity. The system and process is especially suitable for recovering brine and removing sulfate impurity from a brine stream in a brine electrolysis plant. In a conventional system, the heat exchanger typically used to cool the feed stream can be omitted if the dilution stream is provided at a temperature suitably lower than that of the feed stream.

Title: Method and device for compressing and storing data based on sparse matrix
Inventor: LIU DAOXIN
IPC: G06F5/00
Filed: 2014-11-18
Abstract: A method and device for compressing and storing data based on a sparse matrix are disclosed. According to the method, attribute data and value data of a first data are respectively stored, that is, the attribute data of the first data and an attribute identifiers corresponding to the attribute data are stored in the first storage file, and the attribute identifiers corresponding to the attribute data are set as dimension data for determining the first data. Thus second storage file only stores the dimension data and the single value data. In conventional art, five storage domains are used to store the sparse matrix, where real data value is stored in a data value domain. Since many of the data values of each node are the same, and the same data are stored repeatedly, thus storage space is wasted.
