A system for removing or reducing the accumulation of fouling deposits within furnaces and heat exchangers in industrial systems by introducing a periodic steam blast. The steam blast is directed into the process stream from which fouling deposits precipitate onto the heat exchanger surfaces. The steam blast increases the flow rates, creates turbulence and increases the temperature within the heat exchanger to dislodge foulant in both soft and hardened states from internal surfaces upon which foulants have adhered and accumulated.

An inner surface of a thermosyphon reboiler is engraved. The thermosyphon reboiler includes a first side configured to receive a liquid and a second side configured to receive a heating fluid. The thermosyphon reboiler is configured to transfer heat from the heating fluid at the second side to the liquid at the first side to boil the liquid at the first side. Engraving the inner surface of the thermosyphon reboiler includes engraving a pattern across at least a portion of an inner surface of the first side of the thermosyphon reboiler. The pattern has a specified depth that increases a heat transfer surface area of the first side of the thermosyphon reboiler. The engraved pattern prevents film boiling from occurring at the inner surface of the first side of the thermosyphon reboiler.

A mobile mechanical vapor recompression evaporator system including a horizontal vapor separator and a horizontal forced circulation heat exchanger. The horizontal vapor separator can include a generally cylindrical housing configured in a generally horizontal orientation. The housing can include at least one product chamber having at least one product passage configured to receive at least one product. The housing further includes at least one vapor chamber having at least one vapor passage and at least one vapor window located between the at least one product chamber and the at least one vapor chamber, wherein a portion of the at least one product evaporates in the product chamber to produce a vapor that passes through the at least one vapor window into the at least one vapor chamber, and is discharged through the at least one vapor passage.

Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

A production apparatus of sucrose-6-ester is disclosed and includes a distillation separation tank, a reaction tank, and a condensated water collection tank, where the distillation separation tank is arranged above the reaction tank and the condensated water collection tank, and includes a shell and a heating-roller distillation device including a plurality of heating rollers arranged from top to bottom between front and rear side walls of the shell; two ends of the U-shaped plate are respectively fixed to bottoms of the front and rear side walls; a feed pipe is provided at a top of the shell, the condensated water outlet pipe is arranged at a bottom surface of the shell and is connected to the condensated water collection tank, and the liquid evaporation residue discharge pipe penetrates through the bottom surface of the shell, is connected to the U-shaped plate, and is connected to the reaction tank.

Disclosed herein is a low-pressure drop ethylbenzene evaporator, comprising a double-layer structure consisting of a heat exchange unit and a gas-liquid separation unit, the upper layer and the lower layer thereof being connected via an intermediate pipe. The top of the gas-liquid separation unit is provided with an exhaust pipe, and the bottom is provided with a separated liquid return pipe. The heat exchange unit comprises a housing side and a heat exchange pipe, the bottom of the housing side being provided with a liquid flow inlet, and a low-pressure vapor feed pipe being disposed on a side wall of the housing side, located below the heat exchange pipe and close to the position of the heat exchange pipe. In an energy saving process for ethylbenzene vaporization of the present application, a large amount of heat is recovered by means of a main cooler to generate a vapor at 6-32 kpaA, which is used for primary vapor distribution of the ethylbenzene vaporizer design of the present application after being pressurized by a compressor, and is used to replace supplemental 0.21 MPaG low-pressure vapor for a vapor pipe network of a related device, greatly reducing consumption of low-pressure steam in the reaction system, as well as decreasing the amount of circulating water used in the device. The process only consumes the power consumption of a compressor, and saves a large amount of low-pressure vapor and circulating water.
