Study of Coke-oven Gas Desulphurization and Methods to Improve Sulphur Quality
Abstract: The coke-oven gas has high calorific value and can be used for the burning process. The coke-oven gas coming out from the coke-oven department contains impurities like Sulphur, Ammonia, Tar, and Naphthalene. Sulphur is the major impurity; it is very harmful and poisonous to the environment. So the removal of sulphur plays an important role in the purification of coke-oven gas. The sulphur extraction can be done by absorption using …

Doping of Cerium, Boron and Sulphur with ZnO Nanoparticles and their Impact on Lattice Parameters, Studied through UDM Model
Abstract: Un-doped and tri-doped ZnO nanoparticles were successfully synthesized by the simple sol-gel method. Tri-doped nanoparticles of ZnO were prepared by using Ce, B and S as a dopant in concentrations of 1, 2 and 4 wt% with respect to ZnO. The effect of Ce, B and S on the ZnO nanoparticles was investigated by using X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) techniques against particles …

A Comparative Analytical Study on Gandhaka Ointment Prepared by Two Different Oleaginous Bases – As a Thesis Article
Abstract: Gandhaka (purified sulphur) is broadly used in Ayurvedic dermatological preparations, particularly in Malahara Kalpana (ointment formulations), due to its well-known antimicrobial and skin-healing properties. Although classical Ayurvedic texts, such as Rasa Shastra and Bhaishajya Kalpana, do not directly mention Gandhaka ointment, Rasatarangini by Acharya Sadanand Sharma describes four discrete methods for preparing Gandhaka Taila (sulphur-infused oil). In this study, the third method was selected to prepare Gandhaka Taila using two …

A Critical Review of Gandhaka & Its Shodhan Research Work with Special Emphasis on the 1st Method Following Rasatarangini
Abstract: Background: Ayurveda is an ancient healthcare system that influences many modern treatments. One of its key branches, Rasa Shastra, studies the health benefits of strong minerals and metals like mercury, sulphur, mica, and black bitumen. Among these, sulphur is critical for detoxification, blood purification, and digestion, being the third most common element in the human body after calcium and phosphorus. Before sulphur is used in Ayurvedic medicine, it must be …

Steel corrosion about application of inhibitors
Abstract: In chronology of prevention of irreversible degradation of metals, inhibitors to corrosion have studied to inhibit use of toxic inhibitors. Prevention of toxic inhibitors has further studied to explore non-toxic inhibitors prepared from biological origins, e.g. plant originated or underwater organisms or expired drugs. Toxic organic inhibitors are further studied to select those in which toxicity is removed by dilution of processing chemical. If water pipelines are considered use of …

Polymeric Coating Applied for Corrosion Protection of Mild Steel in Corrosive Medium
Abstract: Mild steel is coated with a polymer layer of polybutadiene for protection. However, this coating does not effectively safeguard the metal in environments containing moisture, sulphur dioxide, or chloride. These pollutants interact with the polybutadiene-coated surface, creating a highly corrosive atmosphere. Moisture condenses on the coated metal surface and absorbs sulphur dioxide, forming sulphuric acid. This acid initiates both chemical and electrochemical reactions with the polymer-coated metal, accelerating the corrosion …
