An improved vaporizer part, such as an evaporator element of a disinfection device is for an aqueous solution of hydrogen peroxide. The evaporator element includes one, and/or a branching, meandering structure, in which the straight sections of the groove are joined by 180-degree meanders near edges of the evaporator element. An end pit with an overflow guard is for overflown liquid. Heating elements are used both in connection with the evaporator element to enhance evaporation and on the inner surfaces of the device to prevent condensation. An air blower creates desired vortices near the surface of the evaporator element. The air control element also makes the air flow more laminar. The actual travel of the liquid on the evaporator element functions gravitationally on an inclined surface, and the capillary effect increases the evaporating area of the liquid. A disinfection device includes the vaporizer part.

A method is described herein, comprising vaporizing a glycol material by thermal contact with a heating medium to form a vaporized glycol stream, increasing a pressure of the vaporized glycol stream to form a pressurized glycol stream, and increasing a temperature of the heating medium by thermally contacting the heating medium with the pressurized glycol stream.

The present disclosure is a method of removing contaminants from a feed stream comprising said contaminants and process liquid by bringing the feed stream into contact with a heated heating fluid in or in proximity to a separation vessel thereby causing process liquid to vaporise and flow out of the separation vessel as vapour, after which it can be recovered. Embodiments of the method may include using a heavy heating fluid whose density is higher than that of the feed stream and/or vigorously agitating the pool of heating fluid in the separation vessel.

The present invention discloses a preparation process of food-grade potassium dihydrogen phosphate, wherein phosphoric acid prepared from wet-process phosphoric acid is used for the preparation of high-purity potassium dihydrogen phosphate. The preparation process of food-grade potassium dihydrogen phosphate provided in the present invention effectively reduces the preparation cost of the high-purity potassium dihydrogen phosphate and has the advantage of high process controllability, and by such a process, high-purity potassium dihydrogen phosphate crystals that meet the food-grade requirements can be produced, which crystals have uniform particle size distribution and comprises few fine powder, having a very high market value.

The present invention is related to an advanced control method—including a fast response method—to stabilize, optimize and or maximize the output flow of an evaporation unit via ultrasonic controlled sound or vibration applied to the said evaporation unit. The invention further provides equipment wherein said method is being implemented, such as an evaporation or separation unit.

A cryogenic solid-liquid extractor comprises a reboiler for evaporating an extraction solvent; a cryogenic heat exchanger for condensing the vaporized extraction solvent to a liquid extraction solvent by passing the vaporized extraction solvent through a container cooled by a cryogenic cooling agent comprising a mixture of a cryogenic solvent and a compressed, liquified or solidified gas to cool the extraction solvent to a temperature below the freezing point of water and above the freezing point of the extraction solvent; a cryogenic extractor for passing the condensed liquid extraction solvent through a solid organic material to extract solvent-soluble material, but not water-soluble material, from the solid organic material, wherein the cryogenic solid-liquid extractor returns the condensed liquid extraction solvent containing extracted material to the reboiler to repeat the vaporization and condensation cycle.

The present invention relates to an improved process for the production of alkanesulfonic acids.

Disclosed are a process for operating a flashline heater and a flashline separation system. In the process and system, heat is supplied to the flashline heater by a first steam stage followed by a second steam stage. The steam pressure is controlled by a steam control system such that the pressure in the first steam stage is not equal to the pressure in the second steam stage. Also disclosed is a process for retrofitting a steam control system in a flashline separation system of an olefin polymerization system at least by changing the number of steam stages in the flashline separation system to include a first steam stage followed by a second steam stage, and changing the stream pressure control scheme such that the pressure in the first steam stage is independently controlled to be not equal to the pressure in the second steam stage.

An apparatus capable of heating a liquid may provide a valve assembly configured to receive an incoming liquid from a bulk source. The valve assembly may control the flow of the liquid to a source vessel via a pipe system. The pipe system includes a first pipe directly connected to the valve assembly and a second pipe downstream from the first pipe and connected between the first pipe and the source valve. The second pipe is heated with a heating system that surrounds the second pipe, and the second pipe has a larger diameter than that of the first pipe.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first gas separation followed by pressure reduction and then a second gas separation. Indirect follows the second gas separation and then three-phase separation.
