Perancangan Mesin Sentrifugal Decanter Pati Sagu

Indonesia is a country that has the largest area of sago in the world. Sago processing is currently done manually so that the production capacity of sago that can be produced is still very low. Centrifugal decanter machine is a machine that functions to precipitate and separate sago starch in order to increase capacity and shorten production time in sago flour processing. This study was carried out by observing a sago factory in the Tanah Baru area, Bogor with the amount of wet starch that can be obtained in a day that is 800 kg. The design of this centrifugal machine is carried out using the Pahl and Beitz design method. This machine consists of six sub-assemblies consisting of the frame, the slurry unit, cover, bowl and scroll, the successor round unit, and the motor and support. Based on the design results, the construction of a centrifugal decanter machine with the ability to precipitate and separate sago starch with a capacity of 8.5 m3/ hour with a bowl diameter of 195 mm and a pool height of 10mm. The deposition process occurs with the centrifugal force in the bowl with a rotational speed of 3000 rpm which is driven by an electric motor with a capacity of 7.5 HP (5.5 kW). Separation of starch with liquid occurs due to the difference in the rotation of the resulting screw to the bowl of 33 rpm. The rotation mechanism on the scroll is produced by different electric motors with 3 HP (2.2 kW) power.

Barium-Promoted Ruthenium Catalysts on Yittria-Stabilized Zirconia Supports for Ammonia Synthesis

The cost-effective, small-scale, distributed synthesis of ammonia depends on effective catalysts and processes that operate under modest elevated pressure (i.e., p < 20 bar) conditions. The present paper considers Ru as the active catalyst supported on yittria-stabilized zirconia (YSZ). The addition of alkali and alkaline-earth metal promoters is found to increase synthesis rates by an order of magnitude. The rate enhancement is largely insensitive to the promoter concentration, with Cs outperforming Ba and K by a factor of 2. However, Ba is found to be stable whereas Cs degrades more rapidly, which is attributed to the low melting point of its oxide. At 400 °C and 1.0 MPa, the specific synthesis rate over Ba–Ru is measured to be approximately 1410 mmol gRu–1 h–1, higher than the most active oxide-supported Ru catalysts reported in the literature. The rate becomes inhibited by H2 absorption at low temperature (below 350 °C), but lower H2/N2 ratios enable the rate to remain comparable to what is observed i...

Combined Computational and in Situ Experimental Search for Phases in an Open Ternary system, Ba–Ru–S

Rapid materials discovery in inorganic chemistry should combine predictive computational tools with fast experimental syntheses. We apply such a tandem approach to explore the Ba–Ru–S phase space, where no ternary compounds are yet known to exist. Related ternary oxide ruthenates and ternary iron sulfides exhibit interesting electronic properties due to d-electron correlations, such as superconductivity, metamagnetism, and quantum phase transitions. We use a combination of evolutionary algorithms and density functional theory to inform traditional and in situ diffraction methods. In the course of our investigation, we find that convex hull constructions of the binary constituents inform interpretation of the ternary hull, which in this case has two compounds near thermodynamic stability. Our experimental study does not reveal formation of the candidates BaRu2S2 or BaRuS3, but it does provide the structure of a high-temperature polymorph of BaS2. This methodology can be exploited to study other ternary sys...
