hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Formulation and In-vitro Evaluation of Aceclofenac Microcapsules
Aceclofenac was formulated as novel enteric microcapsules for improved delivery to the intestine using the polymer ethyl cellulose as the retardant material. Micro encapsulation of aceclofenac was done to achieve a controlled drug release profile suitable for per oral administration. Aceclofenac was used as core and microcapsules were prepared by an emulsion solvent evaporation method. The prep...
متن کاملTHE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
متن کاملFormulation and In Vitro Evaluation of Acyclovir Mucoadhesive Microspheres for Intravaginal Application
The purpose of the research was to formulate microspheres of acyclovir (ACV) using mucoadhesive polymers, sodium alginate and chitosan. Calcium chloride was used as the ionotropic gelling agent. Sodium alginate was crosslinked by calcium chloride leading to a slower release of the drug. Chitosan which is a cationic polymer interacted with sodium alginate, an anionic polymer, to form an interpol...
متن کاملPurification and Properties of Bakers' Yeast Trehalase.
Since recent surveys of insect hemolymph (1, 2) have shown that trehalose is the major blood sugar, the hydrolytic enzyme trehalase has also awakened the interest of investigators. A purified preparation of the enzyme from Galleria mellonella (3) and from Phormia regina (4) was recently obtained and some of its properties described. The biosynthesis of trehalose with an enzyme preparation from ...
