‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

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. ...

Systematic Studies to Correlate Microcalorimetry with Stability Studies on Liquid Formulations of Various Protein Drugs

The Prosthetic Group of Sulfhemoglobin by Felix Iiaurowitz*

Treatment of hemoglobin with H&S and 02 gives rise to the formation of a green pigment, sulfhemoglobin. In contradistinction to the transformation of hemoglobin into HbOz, HbCO, Meth-Hb, and other hemoglobin derivatives the transformation into sulfhemoglobin is not reversible. The nature of this reaction is as yet unknown (1). An attempt.was made therefore to isolate the prosthetic group of sul...
