China Drying Network Recently, France’s Suez Environment Group announced that its joint venture Yangzhou Sino-French Environmental Co., Ltd. has obtained a 30-year contract worth 234 million euros to operate the Yangzhou sludge drying project, of which Suez Environmental Group holds 24 million euros. According to the agreement, Yangzhou China and France will exclusively provide Yangzhou residents and industrial customers with safe, energy-saving and environmentally friendly sludge drying services in the next 30 years. The project is planned to be put into operation in 2015, with a daily processing volume of 300 tons for the first phase of the project. With the needs of urban development, it is expected that the daily processing volume of the project will reach 500 tons.
It is reported that Suez Environmental Group has taken the lead in 2009 to introduce the Group's patented Deloitte-based sludge treatment process INNODRY2E for the Chinese market, and established the first sludge drying treatment plant in the Tangjiabu Wastewater Treatment Plant. In 2011, the group built the first sludge drying treatment plant in Jiangsu Province in Suzhou Industrial Park.
According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
Crude paraffin wax has a higher oil content and is mainly used for making matches, fiberboard, tarpaulin, etc. Fully refined paraffin and semi-refined paraffin are widely used, mainly used as components and packaging materials for food, oral medicine and certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, used for fruit preservation , Insulation of electrical components, improve rubber aging resistance and increase flexibility, etc.
Paraffin wax is a mixture of hydrocarbons extracted from certain distillates of petroleum, shale oil or other bituminous mineral oils. The main component is solid alkanes, odorless and tasteless, and white or light yellow translucent solids. Paraffin wax is non-crystalline, but has a clear crystal structure. There is also artificial paraffin.
Paraffin wax is a kind of petroleum processing product, a kind of mineral wax, and a kind of petroleum wax. It is a flake or needle-shaped crystal obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, pressing and dewaxing of lubricating oil fraction obtained from crude oil distillation, and then solvent deoiling and refining. Used to make higher fatty acids, higher alcohols, matches, candles, waterproofing agents, ointments, electrical insulating materials, etc.
