simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Sunn hemp cellulose graft copolymers polyhydroxybutyrate composites: morphological and mechanical studies
For the synthesis of biocomposite materials for useful applications, it becomes necessary to modify the surface of natural fibers through chemical treatments. Morphology, structure and properties of natural fibers have an obvious effect on the mechanical properties of the biocomposite materials. It is thus necessary to know the morphology, thermal stability and crystalline behavior of original ...
متن کاملSunn-Hemp Utilized as a Legume Cover Crop for Corn Production
the winter, chemically terminated in the spring, and then corn is planted into the surface residue. Corn is typically The benefits of winter legumes as cover crops for corn (Zea mays planted early in the growing season, which forces an L.) are diminished by the earliness of corn planting in relation to early termination date. A termination date at least 14 d biomass and N production by the legu...
متن کاملSunn hemp cover cropping and organic fertilizer effects on the nematode community under temperate growing conditions.
Field experiments were conducted in Maryland to investigate the influence of sunn hemp cover cropping in conjunction with organic and synthetic fertilizers on the nematode community in a zucchini cropping system. Two field treatments, zucchini planted into a sunn hemp living and surface mulch (SH) and zucchini planted into bare-ground (BG) were established during three field seasons from 2009 t...
متن کاملDesign and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton
This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...
