An hybrid absorption-hydration method was adopted to recover C2H4 from C2H4/CH4 binary gas mixtures and the hydrate formation conditions of C2H4/CH4 mixtures was studied experimentally in diesel in water (w/o) emulsions. Span 20 at a concentration of 1.0 wt% in the aqueous phase was added to form water in diesel emulsions before hydrate formation and then hydrate in diesel slurry was separated ...

Three different commercially available molasses-based supplements were evaluated for their effects on the performance of preconditioning calves during the fall of 2002. One hundred and forty calves (mean body weight, 465 lb) were randomly allotted to one of four treatments. Treatments offered were: 1) 16% crude protein fortified molasses slurry, 2) 16% crude protein fortified molasses slurry pl...

ISSN 2277 5056 | © 2012 Bonfring Abstract--Fluidization is an operation in which solid particles are kept under suspension supported by the upward flow of liquid/gas phase. In classic fluidization the solids density are higher than the liquid, where as in Inverse fluidization the solids density are lower than that of continuous liquid phase. The phase holdup measurements in three phase classic/...

Hydrate plugging is the major challenge in the flow assurance of deep-sea pipelines. For water-in-oil emulsions, this risk could be significantly reduced with the addition of anti-agglomerants (AAs). Hydrates often form from water-in-oil emulsions and the measurement of emulsion and slurry viscosity constitutes the basis for the application of hydrate slurry flow technology. In this work, using...

Co-digestion of cattle slurry and maize has been shown to have benefits for both, improving the biogas yield of the slurry and stability of digestion of the maize. The effect of increasing the total loading rate from 3 to 6 g VS l(-1) day(-1) on the co-digestion of cattle slurry and maize, mixed at equal volatile solids volumes, was investigated in laboratory-scale continuously stirred digester...

nt matter & 2007 IAgrE. emseng.2007.03.037 hor. : [email protected] Research on the incidence and effectiveness of natural crusting on slurry storage as a means of ammonia emission abatement was undertaken in studies at farm-scale, pilotscale and on a small-scale. At the farm-scale, slurry crusting was found to be commonplace across a large proportion (ca 80%) of slurry storage facilities, d...

This study investigated the effectiveness of vegetated buffer strips for removing contaminants in runoff from grassed plots (slope 15%) after application of cattle slurry. Plots (8 x 8 m2 or 8 x 3 m2) received slurry or inorganic fertilizer, and then simulated rainfall (1, 7 and 21 days after slurry/fertilizer application); after each event, runoff and percolates were sampled at various distanc...

Animal manure is an important source of N for crop production. Part of the manure N is bound in organic compounds and must be mineralised in the soil before it can be utilised by plants. The composition of animal manure is influenced by the diet fed to the animal. We have studied the effects of pig and dairy cattle feed composition on the turnover and potential utilisation of manure N. Dairy co...

Although talc slurry pleurodesis is effective for control of malignant pleural effusions and recurrent pneumothorax, the mechanisms of pleurodesis remain incompletely defined. We instilled 70 mg/kg of sterile asbestos-free talc slurry into the pleural space of New Zealand white rabbits and studied the inflammatory response at 1, 2, 3, 7, 15, 30, 60, 90, and 120 days by observing pleural fluid a...

While many small dairy farms have shut down milk production, the livestock density and number of livestock farms have increased in certain regions in western and central Finland during recent decades. At present, most dairy farms prefer almost continuous grass cultivation to crop rotation with cereals and grasses. Consequently, slurry is spread onto fields of silage grass instead of using earli...
