With the method of theoretical analysis, this thesis, systematically analyzed the limitations of the present theory of accounting in recycle economy and the reasons for that, analyzed the characteristics of accounting in recycle economy, and, according to the internal demand of recycle economy, put forward brand new development orientation of theory of accounting that would be suitable for recy...

The simulated moving bed (SMB) process has been extensively used in industrial separations for binary and pseudo-binary separations. In pseudo-binary mixtures because the desired component is the most or least retained, the other components do not have to be separated. The UOP Parex process for p-xylene purification is an example. When non-target components have similar adsorption behaviors, th...

The upgrading of low quality crude natural gas (NG) is attracting interest due to high demand of pipeline-grade gas in recent years. Membrane processes are commercially proven technology for the removal of impurities like carbon dioxide from NG. In this work, cross flow mathematical model has been suggested to be incorporated with ASPEN HYSYS as a user defined unit operation in order to design ...

In order to study the performance and mechanisms of excess sludge reduction in the activated sludge that incorporates the Cannibal Process, laboratory activated sludge systems incorporating an anaerobic bioreactor into the sludge recycle stream were operated. In this study, the solids production in the Cannibal system was about 35-40% of the conventional system under steady state conditions. Th...

The recovery and concentrate grade, used simultaneously, are the most widely accepted measures of assessing metallurgical performance. Meanwhile, new challenges are being found with more complex ores around the world, a new methodology to evaluate flotation circuits more accurately is used to keep the Mineral Industry afloat in a changing world by increasing revenues. The flotation process is d...

Process variation reduces a pipeline’s maximum attainable frequency by creating unbalance in the stage delays. As a result, the pipeline ends up cycling with a period close to that of the slowest pipeline stage. ReCycle was proposed in ISCA 2007 as a framework for comprehensively applying cycle time stealing to balance the stage delays under process variation, thereby allowing the pipeline to c...

The application of process control automation software for the recycle of peroxide bleaching rinse water to fabric scouring on a continuous preparation range is presented. Analytical data taken on wastewater samples document operating conditions of the preparation range and the quality of the recycle water. An economic analysis of the recycle process and the cost of range modifications to insta...

The Recycling rate among developing nation is very low and the number of waste is increasing every day. Although many steps have been taken such as through national campaign, yet the recycle rate remains unchanged especially in Malaysia. Thus, the smart recycle bin is proposed to give a reward to public user who thrown the recyclable waste into the innovated smart recycle bin by giving points (...
