[Poisoning by CO2 in a silo].

Palladium composite membrane with high reversibility of CO2 poisoning

A palladium membrane was prepared using the electroless plating technique (ELP) for the separation and purification of hydrogen from a gas mixture. Depending on operating conditions, hydrogen flux from the membrane was in the range of 0.012-0.023 mol.m-2.s-1. The membrane performance in the presence of CO2 was investigated. The results of the GC analysis showed that at a feed concentration of 1...

Silo Effect a Prominence Factor to Decrease Efficiency of Pharmaceutical Industry

To be sure, all the industries try to be involved in globalization with a constant trend to find out ways to increase productivity across different functions within an organization to maintain competitive advantage world. Pharmaceutical industries are not exceptional and further are based on fragmentation. So these kind of companies need to cope with several barriers such as silo mentality that...

Experimental Determination of the Optimum Ball Impacts for Solution of Silo Obstruction (RESEARCH NOTE)

A number of considerations should be taken into account in design stage to avoid the foregoing malfunctions of vertical silos containing ore concentrate. One of the silo problems is obstruction at the outlet which blocks the material flow. There are procedures, depending on the material properties and silo dimensions, to solve this problem. A common way is impacting the silo wall by manual hamm...

Effect of Material Wet on Silo Obstruction Solution by Impact (TECHNICAL NOTE)

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...
