Ferric chloride from crude copperas
… copperas is as a coagulant in water treatment. Crude copperas, as produced, does not meet these specifications and must be refined and reworked before it is suitable for use. Consequently, in many instances no attempt is made to make further use of the copperas and it is dumped aside as refuse. …

Sulfur forms in crude viscose rayon
A method of analysis of the total sulfur in crude viscose rayon was developed. This consisted of extraction of the sulfur with sodium hydroxide solution, oxidation to sulfates with bromine, and precipitation as barium sulfate. This method is accurate to one percent. A more rapid method for the …

Predictive analytics for crude oil tanker markets
Tanker markets are one of the many markets to experience extreme volatility, historically realizing drastic swings in earnings of up to 260% week over week. This volatility has placed pressure on tanker market participants to forecast future returns, create guidance for their investment decisions, …

Chemistry of alkylaromatics in crude oil upgrading
Due to the rise in demand of crude oil over the long term, technologies to upgrade crude oil need to be developed to ensure maximum use efficiency of future oil sources. In typical carbon rejection processes, coke formation is a common phenomenon that would lead to decreased yield of upgraded oil. …
