گاز طبیعی به علت تمیزی و آلودگی بسیار پایین، محتوای انرژی و دمای شعله بالا یک سوخت ایده آل بوده و مصرف بسیار بالای سوخت در عصر جدید اهمیت استفاده از گاز طبیعی را صد چندان نموده است. با افزایش مصرف کاز طبیعی بعضی از فرایندهای تصفیه گاز از لحاظ اقتصادی به صرفه نبوده و از رده خارج شده اند و بعضی نیز طی مراحلی بهینه شده اند. فرآیند جذب یکی از مهم ترین روش های جداسازی در صنایع شیمیایی است که در حی...
Global gas flaring is difficult to sense, a tremendous source of wasted revenue, and causes ecological problems. We use satellite sensors to predict gas flares’ sizes. We tested regression and classification algorithms, along with anomaly detection using k-means, and found that linear regression and 2-class SVM are almost as good as the full-tilt sensor model produced by the National Oceanic At...
Observations of the green and red-doublet emission lines have previously been realized for several comets. We present here a chemistry-emission coupled model to study the production and loss mechanisms of the O(1S) and O(1D) states, which are responsible for the emission lines of interest for comet 67P/Churyumov-Gerasimenko. The recent discovery of O2 in significant abundance relative to water ...
We present an overview of solar flares and associated phenomena, drawing upon a wide range of observational data primarily from the RHESSI era. Following an introductory discussion and overview of the status of observational capabilities, the article is split into topical sections which deal with different areas of flare phenomena (footpoints and ribbons, coronal sources, relationship to corona...
We present high time-resolution multicolour observations of the quiescent soft Xray transient V404Cyg obtained with ULTRACAM . Superimposed on the secondary star’s ellipsoidal modulation are large flares on timescales of a few hours, as well as several distinct rapid flares on timescales of tens of mins. The rapid flares, most of which show further variability and unresolved peaks, cover shorte...
The spoilage potential of six bacterial species isolated from cooked and peeled tropical shrimps (Brochothrix thermosphacta, Serratia liquefaciens-like, Carnobacterium maltaromaticum, Carnobacterium divergens, Carnobacterium alterfunditum-like and Vagococcus penaei sp. nov.) was evaluated. The bacteria were inoculated into shrimps, packaged in a modified atmosphere and stored for 27 days at 8 °...
Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]
