Problems solved by technology

The aim of this publication is to cleanly separate the pellets from the cooling lubricant, but it does not address the recovery of the cooling lubricant in a high-quality form if desired, e.g. for reuse in a sawing process

Embodiment Construction

[0029] In two separate experiments, residues contained varying levels of residual oil. This shows that residues with a lower oil content are significantly more difficult to handle than residues with a higher oil content. The reason for this is in particular that residues with a lower oil content have a significantly worse coefficient of thermal expansion than residues with a higher oil content.

[0030] The residue R is preferably subjected to one or more pretreatments 1, such as washing or homogenization methods. In another corresponding pretreatment 2, foreign constituents can be substantially removed.

[0031] At this point, the pretreated residue is transferred to a receiving hopper 3 , after which it is transferred by means of a pump 4 into a first mixing kneader 5 . The pump 4 is preferably a Moino pump, which is also understood to mean a progressive cavity screw pump. Experiments with gear pumps were unsuccessful.

[0032] The transfer to the first mixing kneader ta...

Abstract

In a method of processing and / or recovering and / or reutilizing residues, especially from refinery processes, containing a base substance, especially comprising hydrocarbon, for example kerosene, and oil, and also metallic residues, the residues are to be introduced into a first reactor (5) in which a portion of the volatile residues evaporates and then is transferred into a second reactor (10) and solidifies therein by cooling, optionally promoted by evaporation of water.

Description

technical field [0001] The invention relates to a process for the preparation and / or recovery and / or reuse of residues, in particular from refining processes, containing base substances, in particular hydrocarbons and oils such as kerosene and metal residues . Background technique [0002] Many industrial methods and processes produce residues consisting, for example, of hydrocarbons, oils and metals. All three components are extremely valuable and should not simply be disposed of. [0003] The most important sources of residues with hydrocarbons are eg mineral oil refining processes. These processes include atmospheric distillation, vacuum distillation, preparation of fuel oils and fuels, alkylation with sulfuric acid, polymerization of mixtures of propylene and butane with phosphoric acid, high temperature isomerization, preparation of lubricating oils, rectification, tube furnace distillation, boiling distillation , coking, catalytic cracking, reforming, hydrofining, h...
