Process for recovery and treatment of a diverse waste stream

A process for evaporating out particular compounds from a waste stream containing hydrocarbons, through heat retention, the process comprising the following steps:

• a) providing a chamber for receiving a waste stream;
• b) heating the chamber through an external heat source to a first temperature;
• c) introducing the waste stream into the heated chamber at the first temperature;
• d) monitoring the heated chamber to detect any deflection in the shape of the chamber wall during heating;
• e) conveying the waste stream through the heated chamber for a certain amount of time so that compounds with boiling points below operating temperatures are vaporized and removed from the stream;
• f) conveying the vaporized constituents via an inert gas medium through an air cooler;
• g) repeating the steps of a) through f) through subsequent externally heated chambers, each of the chambers retaining the waste stream at a temperature higher than the preceding temperature and for a particular amount of time, to separate compounds out from the waste stream depending on the boiling point of the compound to be vaporized from the stream;
• and
• h) further processing the bas stream to remove impurities such that the stream can be recycled back to the distillation unit.

A process for vaporizing and removing compounds from a waste stream containing hydrocarbons, through heat retention, the process comprising he following steps:

• a) providing a series of externally heated chambers;
• b) introducing the waste stream into a first chamber of the series which is at a first temperature;
• c) conveying the waste stream through the first chamber for a certain amount of time so that compounds with boiling points below operating temperatures of 300.degree. F. are vaporized from the waste stream;
• d) conveying the vaporized constituents via an inert gas medium through an air cooler;
• e) gravity feeding the remainder of the waste stream through a second chamber of the series of chambers for a certain amount of time so that compounds with boiling points of between 300.degree. F. and 900.degree. F. are vaporized from the waste stream;
• f) gravity feeding the remainder of the waste stream through a third chamber in the series of chambers so that compounds with boiling points between 900.degree. F. and 2100.degree. F. are vaporized from the stream;
• g) conveying the vaporized streams from the first chamber, second chamber, and third chamber, via an inert gas medium for removal of entrained solids within the gas stream;
• and
• h) conveying the vapor laden inert gas stream to an air cooler for recondensation of the stream, and further processing the stream.
