Dsc wax appearance temperature
WebJun 11, 2024 · Wax Appearance Temperature, also known as cloud point, is very important measurement in the oil industry. It is the temperature where the first wax crystal starts to precipitate out from crude oil. When the wax molecules develop into a solid structure, it can cause crude oil to experience a gel fluid with low flow ability. WebFurthermore, DSC analysis indicated that pure monoolein may be problematic with respect to melting transitions between 25.4 and 33.4°C. Solubility data for SME–MAG mixtures indicated a broad transition temperature range from solid at low temperature to liquid at temperatures exceeding 60°C.
