The present invention is a pyrolysis system including a furnace for batch pyrolysis processing. The pyrolysis system receives scrap tires or other organic waste materials as inputs and performs batch pyrolysis processing to produce pyro-products as outputs. The pyro-products produced include pyro-vapors from which are condensed pyro-oil with a surviving pyro-gas and also include pyro-solids, particularly pyro-carbon (carbon char) and steel. The pyro-oil includes an inhibitor.

Embodiments of the invention provide systems and methods for water treatment and/or desalination.

The present invention is a aroma recovery equipment from gases exhausted of fermentation vats comprising a first recovery group (100) comprising a first condenser (110) operating at a first temperature of recovered aromas; one second recovery group (200) comprising a second condenser (210) operating at a second temperature of recovered aromas; a cooling group (300) to provide cold by a cooling fluid (301) to said first recovery group (100) via a first fluid connection (302) and to said second recovery group (200) via a second fluid connection (303); control means (400) configured to coordinately control the temperature of said first recovery group (100) and the temperature of said second recovery group (200); and a mobile housing (500) containing said first recovery group (100), said second recovery group (200), said cooling group (300) and said control means (400).

A multi-pass distillation system has a boiling flask with a side exit portal which is functionally connected to a condenser, which is, in turn, functionally connected to one or more cold traps. The condenser condenses wet vapors into liquid while the cold traps protect a pump which is used to suction the air through the system from the boiling flask through the condenser and cold traps. In this manner, one can more accurately collect fractions by way of a sideways exit from the boiling flask, near the top of the flask, with a condenser extending into a body of the spherical flask, such as at a 45 degree angle.

A heat exchanger includes a shell, and a tube assembly disposed in the shell, the tube assembly including at least one tube, wherein the tube has a pair of end sections having a first diameter and a central section extending between the end sections having a second diameter that is greater than the first diameter.

A multi-stage distillation system includes multiple stages, and each stage Si includes an evaporator Ei and a condenser Ci. Each condenser includes a steam chamber in pressure-connection with a steam chamber of each evaporator of the same stage. Each evaporator has a steam chamber outlet connected to a spray inlet of the next evaporator Ei+1, and the outlet of the last evaporator En connects to the spray inlet of the first evaporator E1 with a respective fluid line to form an evaporator circuit. Each outlet of each condenser Ci connects to the one spray inlet of the previous condenser Ci1, and the outlet of the first condenser C1 connects to the spray inlet of the last condenser Cn with a fluid line to form a condenser circuit. A steam line connects between condensers Ci+1 and Ci or between the evaporators En and E1.

The present invention pertains to the recovery, separation and the unique product mixtures obtained by recovery and separation of coal-tar oils produced from low-rank-coal by a novel mild-temperature pyrolysis [MTP] process originating at the point where the vapor phase exits the pyrolysis reactor. Mild-temperature pyrolysis [MTP] takes place below 1200 F. in contrast to the high-temperature pyrolysis [HTP] that is operated at 1600-2000 F. for coke oven processing of metallurgical coke. The yield and composition of coal-tar-oil recovered from MTP are quite different from HTP coal-tar. In order to optimize the oil recovery process, the most appropriate recovery and separation processes therefore also will be different. The MTP process produces coal-tar containing a major fraction of strongly polar compounds mixed with non-polar compounds that separates into several liquid phases and overlap in their distillation ranges. This invention addresses the distinct product fractions obtained from MTP and the integrated multi step oil recovery and product separation process, which is designed with the objective to improve and facilitate the product separation, decrease the required amount of energy for separation and equipment cost for downstream processing.

A multi-stage bubble-column vapor mixture condenser comprises at least a first stage and a second stage. Each stage includes a carrier-gas inlet and a carrier-gas outlet, as well as a condenser chamber containing a condensing bath in fluid communication with the carrier-gas inlet and the carrier-gas outlet. The carrier-gas inlet is positioned to bubble carrier gas from the carrier-gas inlet up through the condensing bath, overcoming a hydrostatic head of the condensing bath. The carrier-gas outlet is positioned with an opening for carrier-gas extraction above the condensing bath, wherein the first-stage carrier-gas outlet is in fluid communication with the carrier-gas inlet of the second stage to facilitate flow of the carrier gas through the condensing bath in the condenser chamber of the first stage and then through the condensing bath in the condenser chamber of the second stage.
