Wax residue treating method and system

Abstract

The invention provides a wax residue treating method and system. The method comprises the steps of 1, heating wax residues to enable wax in the wax residues to stay molten; 2, conducting high-temperature separation on the heated wax residues to obtain molten wax and solid residues; 3, conducting incineration disposal on the solid residues. Through melting and high-temperature separation of wax in the wax residues, recovery of wax in the wax residues is achieved, waste of the wax resource is avoided greatly based on environment-friendly discharge of the wax residues, and economic benefits are increased.

Description

technical field [0001] The invention relates to a solid waste treatment technology, in particular to a slag wax treatment method and system. Background technique [0002] Fischer-Tropsch synthesis usually uses synthesis gas as a raw material to synthesize paraffin-based liquid fuels under catalysts and appropriate reaction conditions. After Fischer-Tropsch synthesis, the catalyst is usually discharged from the Fischer-Tropsch synthesis unit in the form of slag wax. Since the slag wax contains 20-75wt% wax, when the slag wax is treated as solid waste, the wax in the slag wax is usually converted into carbon dioxide and water by incineration first, and the remaining waste residue is treated according to the general solid waste . [0003] Although the above-mentioned treatment method solves the environmental protection discharge problem of slag wax, the wax in slag wax is directly incinerated, thereby causing a great waste of organic matter, and the economic benefit is low. ...
