A recent research study conducted at Sunway University in Bandar Sunway, Malaysia, proposes a new approach for the design of extractive distillation processes that incorporates environmental, health, and safety (EHS) considerations during the entrainer screening phase. The study focuses on two azeotropic mixtures and identifies ethylenediamine (EDA) as the optimal choice for separation based on EHS criteria. The researchers successfully simulated the separation processes using Aspen Plus, confirming the validity of the screened entrainer. This research provides valuable insights into the integration of EHS factors in the early stages of process design. [Extracted from the article]

The article offers information on several types of essential oils including Rangpur Lime oil, kewda oil, and labdanum oil extracts. It states that Rangpur Lime oil contains several constituents including myrcene, limonene, and geraniol. It notes that the kewda oil is obtained through hydrodistillation of flowers of Pandanus fasiculatus. It mentions that labdanum oil extracts features several compounds including furfural, sabinene, and myrcene.

The article presents information regarding the optimization of hydrocracker operations for increase in the amount of distillation. It mentions that an accurate operating window for a hydrocracker enables the increase in diesel production and decrease in lower value materials like light ends. It also informs that the method involved in hydrocracking includes primary cracking of heavier feedstocks and then secondary cracking of middle distillates.

The article offers information from various studies conducted on Cyperus rotundus oil and extract, focusing on its application on flavor and fragrance manufacturing. The oil, which is acquired by steam distillation of the dried tubers, is primarily produced in China and India. Several charts are presented including the percentage composition of the chemotypes of Cyperus rotundus, the composition of the oil and its headspace volatiles, and the structures of sesquiterpenoids found in the oil.

The article informs about the licensing of GT-BTX extractive distillation process of GTC Technology U.S. LLC. for the production of high-purity aromatics at Reliance Industries Ltd., Jamnagar refining and petrochemical complex in Gujarat, India.
