  • Patent number: 9822087
    Abstract: There is provided a manufacturing assembly for the production of an alkylene oxide and a stream of glycol ethers. The manufacturing assembly produces the alkylene oxide and stream of glycol without the use of equipment for separating substantially all of the alkyl alcohol from the alkylene oxide product stream. Thus, the use of additional pieces of equipment can be avoided, or the equipment required to effectuate any required further separation and/or purification may be smaller and/or cheaper to purchase and/or operate.
    Type: Grant
    Filed: February 12, 2016
    Date of Patent: November 21, 2017

  • Patent number: 9273019
    Abstract: There is provided a process for manipulating the amount of alkyl alcohol in a product stream, e.g., such as an alkylene oxide product stream. More particularly, and in contrast to conventional processes wherein substantially all of the alkyl alcohol must be separated and desirably recycled, in the present process, a greater amount of alkyl alcohol may be allowed to remain in a partially refined alkylene oxide product stream. The residual alkyl alcohol is subsequently substantially entirely reacted to form a downstream product, e.g., a glycol ether, which is more easily separated from the alkylene oxide product stream. Indeed, the amount of alkyl alcohol in the partially refined alkylene oxide product stream can be selected based upon the output of glycol ethers, if desired.
