Palm Oil Mill

There is currently no standard for the Specific Energy Consumption (SEC) in the palm oil industry. SEC is a value that can be used as an indicator to measure the optimization level in the use of energy. Indonesia as one of the largest palm oil producing countries requires a standard for energy intensity in the palm oil industry. SEC in palm oil mill is defined in the amount of energy per unit of production (kWh/kg). The classifying method that has been used in this study is K-means cluster analysis with the measurement samples in 14 palm oil mills for 12 months of period. This study has suggested the SEC standard for Indonesian palm oil industry and it is expected to be SEC reference for other studies in the palm oil industry.

This article discusses a study of extrusion’s process of feed-stuff for fish on the developed two-screw extruder. The main technological requirements of fodder-stuff for fish was determined. The results of experimental studies were described, the relation of the specific energy consumption of the temperature and humidity of feed-stuff was defined. The obtained results show that the specific energy intensity of the two-screw extruder is lower than with other devices for the production of fodder-stuff for fish.

The Relationship

Kuzbass coal mines are equipped with powerful mining equipment; it is CME excavator type with bucket capacity from 4.6 m3 to 20 m3. To evaluate the efficiency of the excavation processes, a universal criterion was used – the value of specific energy consumption (kW h/m3). The dependences of excavator efficiency on the quality of rock blasting, estimated by the diameter of the average piece in the shot pile, are obtained. The relationship between the efficiency of excavators CME - 4.6, CME – 8, CME – 12.5, CME – 20, their energy intensity and the diameter of an average piece in the shot pile is determined.

The Moment

Traditional thick-film production technology CCS for almost 20 years not only does not provide the necessary dynamics of growth of specific energy intensity, but also tends to reduce it in order to increase the safety of operation of products. The development of thinfilm technologies and new electrochemical systems with a higher resource (more than 10,000 charge – discharge cycles-20 years of operation) and a higher specific energy (500…1000 W∙h/kg) is considered to be the most important breakthrough tasks at the moment. A promising direction is considered to be the use of elastic conducting matrices based on carbon in the creation of nanocomposite structures. To develop a complex of vacuum thin-film nanotechnologies for creating electrode materials for current sources based on a flexible carbon matrix with a highly developed surface. A complex of vacuum thin-film nanotechnologies for creating electrode materials for current sources has been Developed. Based on the developed electrode material, chemical current sources (CCS), ultra-high-capacity capacitor structures (UCS) and pseudocapacitors and hybrid capacitors were manufactured and studied. Analysis of the results of specific energomasha super powerful capacitor structures (UCS), has superb capacitor structures with metallization, hybrid UCS based on cobaltate lithium capacitors with pseudoeunotia showed that the specific energy consumption of hybrid UCS based on cobaltate lithium capacitors with pseudoeunotia oxide of manganese, have a value exceeding the specific energy of UCS 4.5 and 4.8 times, respectively. The developed technology allows increasing the energy consumption of cells and reducing their internal resistance.The developed complex of vacuum thin-film nanotechnologies allows creating electrode materials based on a flexible carbon matrix with a highly developed surface. The resulting electrode materials can be used in energy storage.

And Behavior

The article presents the results of driving and static tests of pile models with different longitudinal shapes, carried out in laboratory conditions. It was revealed that the specific energy consumption of driving a pyramidal-prismatic pile can either exceed or be less than the specific energy consumption of driving a prismatic pile. Unlike pyramidal piles, pyramidal-prismatic piles have less specific energy consumption for driving. Energy costs for driving pyramidal-prismatic piles, as well as their resistance to pressing vertical loads depend on the length of the pyramidal section and rise with its increase. It has been established that, with the same depth of driving and with the same piles, the specific bearing capacity of the pyramidal-prismatic piles is higher than the prismatic piles and less than the pyramidal pile. The revealed features of the behavior of the pyramidalprismatic piles are due to the influence of the longitudinal shape and the length of the pyramidal part of their shaft on the driving process and behavior under the loads.

Fenugreek Seed

Experiment to identify ambient grinding conditions and energy consumed was conducted for fenugreek. Fenugreek seeds at three moisture content (5.1%, 11.5% and 17.3%, d.b.) were ground using a micro pulverizer hammer mill with different grinding screen openings (0.5, 1.0 and 1.5 mm) and feed rate (8, 16 and 24 kg h-1) at 3000 rpm. Physical properties of fenugreek seeds were also determined. Specific energy consumptions were found to decrease from 204.67 to 23.09 kJ kg-1 for increasing levels of feed rate and grinder screen openings. On the other hand specific energy consumption increased with increasing moisture content. The highest specific energy consumption was recorded for 17.3% moisture content and 8 kg h-1 feed rate with 0.5 mm screen opening. Average particle size decreased from 1.06 to 0.39 mm with increase of moisture content and grinder screen opening. It has been observed that the average particle size was minimum at 0.5 mm screen opening and 8 kg h-1 feed rate at lower moisture content. Bond’s work index and Kick’s constant were found to increase from 8.97 to 950.92 kWh kg-1 and 0.932 to 78.851 kWh kg-1 with the increase of moisture content, feed rate and grinder screen opening, respectively. Size reduction ratio and grinding effectiveness of fenugreek seed were found to decrease from 4.11 to 1.61 and 0.0118 to 0.0018 with the increase of moisture content, feed rate and grinder screen opening, respectively. The loose and compact bulk densities varied from 219.2 to 719.4 kg m-3 and 137.3 to 736.2 kg m-3, respectively.
