De-waxing oli plants is removal of wax and ceresin from oil products (diesel fuels, oils) resulting in improvement of their quality, in particular, in reduction of their setting point. De-waxing is carried out by the following methods: crystallization of the above components from oil product solution, e.g. oil crystallization in ligroin at chilling; selective dissolution of oil products in solvent that doesn’t dissolve wax and ceresin; wax capability to form carbamide complex (carbamide de-waxing) and microbiological method are also applied. Produced wax and ceresin are used as valuable raw materials in various industries
