Micro-interface enhanced mass transfer sodium carbonate absorption carbon dioxide reaction

Micro-interface intensified reactor(MIR)can be applied in series/parallel in the absorption of CO_(2)in industrial gases by Na_(2)CO_(3)due to the ability to produce large numbers of stable microbubbles.This work focuses on the variation pattern of mass transfer characteristics parameters of the reaction gas in Na_(2)CO_(3) solution under the influence of different solution properties and operating parameters in the reaction of CO_(2)absorption by Na2CO3.The mass transfer characteristics parameters include bubble Sauter mean diameter,gas holdup,interfacial area,liquid side mass transfer coefficient,and liquid side volume mass transfer coefficient kLa.The solution properties and operating parameters include Na2CO3 concentration(0.05–2.0 mol·L^(-1)),superficial gas velocity(0.00221–0.01989 m·s^(-1)),superficial liquid velocity(0.00332–0.02984 m·s^(-1)),and ionic strength(1.42456–1.59588 mol·kg^(-1)).And volumetric mass transfer coeffi-cients kLa and superficial reaction rates r of the MIR and the bubble column reactor are compared in the reaction of sodium carbonate absorption of carbon dioxide,and the former shows a greater improvement under different solution properties and operating parameters.The enhanced role of MIR in mass transfer in non-homogeneous reactions is verified and the feasibility of industrial practical applications of MIR is demonstrated.

The Present Situation of IT Outsourcing and Countermeasure

With the market competition intensifies, enterprises focusing on core business has become the most important rules of survival. Therefore, more and more enterprises adopt outsourcing as critical business initiatives due to its effectively reduce costs, enhancing the core competitiveness of enterprises and other characteristics. Duroc, a famous American management scholars had predicted: “In ten to fifteen years within any business background to support not only to do the work of creating turnover should be outsourced.” Do what you do best (your core competency) and outsource the rest. It has become an irreversible trend. In this paper, we will introduce the business value of IT outsourcing, discuss IT outsourcing industry’s strengths and weaknesses, finally we will provide corresponding countermeasures based on the discussion.

Issue in Implementing Customer Operations Performance Center (COPC)

Customer Operations Performance Center Inc (COPC) is the world’s leading authority on Contact Center Operations Management. The COPC 2000 Standard is a comprehensive operating model for Contact Centre Operations. It is a world-wide benchmark and certification for contact centers. As well as an overall performance management system, COPC is designed to reduce costs, increase revenue, and improve service, quality and customer satisfaction. However, many COPC implementation projects failed. In this study, we first review the process of implementing COPC. Then, we identify major barriers in implementing COPC. Organizations should take proper measures in overcoming these barriers to ensure successful implementation of COPC.
