摘要： Disclosed is an integrated process for producing 2,6-naphthalene dicarboxylicacid comprising oxidizing a methylnaphthalene feedstock, hydrodebrominating the crude naphthoic acid product under conditions different from any work known in the art, forming a potassium salt of the acid; disproportionating the potassium salt to produce 2,6 potassium salts of NDA; selectively precipitating K2NDA; selectively precipitating the monopotassium salt of 2,6 NDA(KHNDA); disproportionating the KHNDA into 2,6 NDA and K2NDA; further reacting the 2,6 NDA in a pipe reactor; and drying the product 2,6 NDA by conventional means or directly slurrying directly into a PEN process. The process can tolerate impurities in the economical methylnaphthalene feed and the resulting 2,6 NDA is of high quality with

摘要： A selenium-containing aqueous stream may be used as a quenching water stream and optionally a cutting water stream in a delayed coking process to effectuate the removal of selenium from the selenium-containing aqueous stream resulting in the formation of a selenium-coke product. In addition, selenium may be concentrated in selenium-containing stripped sour water streams by recycling the stream in one or more hydroprocessing units and one or more sour water stripper units and subsequently removed by using a portion of the selenium-containing stripped sour water stream as a quenching water stream and optionally a cutting water stream in a delayed coking process.

摘要： Disclosed is a method for closely linking a process for producing 2,6-naphthalene dicarboxylic acid (2,6-NDA) with a process for producing polyethylene naphthalate, thus eliminating the need for drying 2,6-NDA, handling solid 2,6-NDA, and optimizing particle size of 2,6-NDA which comprises: a) Adding an aqueous slurry of polymer grade 2,6-NDA directly into a process for making PEN, either by directly adding a stream from a 2,6 NDA process into a PEN process, or by adding water to polymer grade 2-6-NDA prior to adding the resulting slurry to a PEN process. b) Removing the slurry water during the first esterification reaction at the same time the water of reaction is removed.
