To reduce inhalable particle and SO(x) pollution from coal-based urban central heating (UCH), China has been vigorously developing natural gas-based UCH for years. The CO(2) emissions of UCH, having an average annual growth rate of 10.3%, accounted for 4.4% of China's total CO(2) emissions in 2009. This paper analyzes the feasibility of replacing UCH with(More)
Microfabracation is the critical technology to obtain microelectromechanical systems (MEMS) parts. Nowadays, microfabrication technologies are usually based on the mask lithography and Focused-ion-beam (FIB) sputtering, which are in fact two and a half dimensional (2.5-D) fabrication and are difficult to fabricate real 3-D parts. Based on the real 3-D(More)
In this paper an integrated operating simulation system (OSS) for a cryogenic air separation unit (ASU) is developed, which can be used for operators’ training, accident and malfunction analysis and prediction of operating result. Based on the method of modularization an ASU’s components are divided by their physical function. The OSS code(More)
