Description:
Descriptive Report of the Invention Patent: PROCESS OF COAL TAR DISTILLATION FOR PRODUCTION OF ELECTRODE PITCH AND DERIVATIVES USING DIRECTLY A INDUCTIVE HEATER AS HEAT SOURCE TO HEAT UP THE MATERIALS IN PROCESS.

The present invention refers to a distillation of coal tar and or petroleum/derivatives, using an inductive heater as direct heating source to heat up the several materials in process, this, create a productive process that doesn't cause any negative impact to the environments, we ignore similar patented process or in this state of technique.

Nowadays electrode pitch is produced under two process that in principle has the same origin, through the heating up and progressive distillation of coal tar or petroleum/derivatives.

The usual process are: . Batch process . Continuous process The normal way to heat up the materials in both process is to burn gas or liquid fuel, being in batch process used electricity (electrical resistances) to complement the heating up.

I) In the continuous process where is practiced the direct heating, using gas or fuel as thermal energy source presents the inconvenient that is you can't guarantee the quality, because you can't avoid some hot

spots in the materials mass that promote some deterioration in final products.

II) When you use gas or liquid fuel you trow in the atmosphere gases (C02-CO-Nox-Sox etc.) that are generated due the combustion, in this process the energethical revenue varies from 60% to 80%.

III) In the batch process, can be used the indirect heating up, through a thermal fluid, that by one way avoid the overheating, in the other hand increase the accident risk due to the thermal oil. This process generate, also, combustion gases from the heating up thermal oil process, in this case, also the thermal revenue is relatively low.

OBJECT Use of inductive heater for the ends named in this solicitation.

The-inductive heater, whose energy revenue is superior at 90% and it doesn't generate any effluent. We can consider it as heating source completely clean and without any environment impact.

This heater is connected to the pumping system that pumps the products and operates with reactors (under vacuum, or not), with boilers attached to distillation columns or connected to some other kind of intermediate or not, equipment involved in this process, object of this solicitation.

A. B- Reactors, with or without vacuum, with or without others alternatives heating sources complementary or accessory, boilers connected or not to distillation columns, intermediate buffers.

A. C- Rectification columns, distillators or secondary reactors.

With the implantation of this process, partially or totally, is observed the following: 1-Significant increase of the energy revenue, what means production cost reduction and reduction of public investment and or private tied up to infrastructure.

2-Significant reduction or elimination of combustion effluents, reducing completely the environmental's impact.

3-Productivity increase when applied, even partially, in existent facilities.

4-Reduction of investment mass in new facilities.

5-Significant reduction of the degree of work accidents in comparison to the conventional process.
