Abstract: Extruded films comprising ethylene vinyl alcohol copolymer (EVOH) with substantially no blow holes therein, are formed by using a pellet feed to the extruder wherein 90-100 wt. % of the pellets pass through an ASTM size 5 sieve and 0-10 wt. % of the pellets are finer than a number 10 mesh (ASTM Sieve size). Uniform feeding to and through the extruder with a lack of bridging of the EVOH pellet feed have been observed.

Abstract: A method of real-time prognosis of a flooding phenomenon in a packed column includes steps as follows. An online data collection step is conducted, wherein a plurality of values of a pressure drop are collected from the packed column under operation. A detrending step is conducted to obtain a plurality of values of a detrended pressure drop. A fitting step is conducted, wherein the values of the detrended pressure drop are fitted with an EGARCH(p, q) model to obtain a value of at least one of model coefficients. A repeat step is conducted to obtain another value of the at least one of model coefficients. A statistical step is conducted, wherein a value of the monitoring statistic is calculated. A control step is conducted, wherein the value of the monitoring statistic is compared to a control limit.

Abstract: A butanol expression cassette includes a butanol production related genes and a fermentation regulatory element. The fermentation regulatory element controls the expression of the butanol production related gene and locates upstream of the butanol production related gene. The fermentation regulatory element includes a promoter, a ribosome binding site and a transcription factor binding site of a fermentation gene. A fermentation in which the fermentation regulatory element involves includes an acetic acid fermentation, an alcohol fermentation, a succinic acid fermentation or a lactic acid fermentation, the butanol production related gene is not the fermentation gene or a gene of an upstream product of the fermentation in which the fermentation gene involves. The present invention provides a recombinant plasmid formed by cloning the butanol expression cassettes in the expression vector. The present invention also provides a butanol production related gene expression method to express butanol production related gene by using recombinant plasmid.
