The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

The synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. To provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...

Sequences of the novel gammaretrovirus, xenotropic murine leukemia virus-related virus (XMRV) have been described in human prostate cancer tissue, although the amounts of DNA are low. Furthermore, XMRV sequences and polytropic (p) murine leukemia viruses (MLVs) have been reported in patients with chronic fatigue syndrome (CFS). In assessing the prevalence of XMRV in prostate cancer tissue sampl...

some formation, such as " single column," or " double column," or " column of fours," according as the width of the road, and nature of the ground permitted. Any one who has been on active service with Indian Field Hospitals and Bearer Columns, must have observed the want of order that prevails, and how the men straggle all over the line of march. I think that all the men of the A. H. N. C. sho...

Sequences and arrays with good auto and cross-correlation are useful in communications and digital , .. 'atermarking respectively. Two-valued autocorrelation is relatively easy to achieve. However, sets of pSfudonoise sequences with good cross-correlation arc small and difficult to find. Here, the cross-correlation for particular shifts of m-sequences and GM\V sequences is analysed by looking a...
