Black liquor concentration using pressure driven membrane separation has long been proposed as a means of achieving energy savings and breaking production bottlenecks. To date, limitations in perfor-mance stability under black process conditions have prevented those promises from being realized outside tightly controlled laboratory settings. In this work, we describe the first successful pilot ...

Methods for processing feedstuffs before analysis can affect analytical results. Effects of drying temperature (corn silage), preservation method (corn grain), and grinding method (corn silage and grain) on starch analysis values were evaluated. Corn silage samples dried at 55 or 105 degrees C and grain samples dried at 55 degrees C were ground to pass the 1-mm screen of an abrasion mill or cut...

Agricultural productivity has increased in Argentina, with cereals yield going from 1.4 to 4.8 tonnes grain ha-1 during the period 1961-2014 [6]. However, in the Province of Buenos Aires, cereals production has changed its composition during the period 2006 2016, with wheat production decreasing from approx.9 mill. to 5 mill. of tonnes and corn production going from 6.1 to 10. 1 mill. tonnes [7...

This paper deals with the identification of MIMO cement mill process using Non-linear Autoregressive with Exogenous Inputs (NARX) models with wavelet network. NARX identification, based on a sequence of input/output samples, collected from a real cement mill process is used for black-box modeling of non-linear cement mill process. The NARX model is considered for two inputs and two outputs of s...

The workplace environment affects the health of workers. Unhygienic conditions are observed in the workplace environment of flour mills as fine organic flour dust gets airborne in the indoor environment of the flour mills. The present work was undertaken to study the health problems related to the workplace environment of flour mill workers. The results show that flour mill workers are receivin...
