A system of fluid sterilization of fluid of vessel is provided, such as sterilization of ballast water for a water vessel. The system incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.

An evaporation device for evaporating hydrogen peroxide is provided. The device comprises a housing body having at least two fluid channels arranged therein. The fluid channels are connected to each other to form a common fluid line between an inlet and an outlet. The housing body also includes and at least one heating element positioned within said housing body for heating said fluid channels. A first fluid channel, directly connected to the fluid inlet, is positioned relative to the at least one heating element such that its inner walls are heated to a first temperature, and a second fluid channel, being directly connected to the fluid outlet, is positioned relative to the at least one heating element such that its inner walls are heated to a second temperature. In some embodiments, said second temperature is higher than the first temperature.

An acid purifier, comprising: a container (1) for an acid to be purified; a heater (2); a condenser (3) including a Peltier semiconductor cooler, a condenser body (600) and a refrigerant temperature sensor; a purified acid liquid collection bottle (4) connected with the condenser; a controller; an integrated liquid level control component (300) for the acid to be purified, connected with the container (1) for the acid to be purified, and arranged in such a way that a liquid level pipe (320), a liquid adding funnel (310) and a waste liquid discharge valve (330) are integrated; and an acid liquid temperature sensor (400, 500) arranged in the acid to be purified.

The present application discloses a desalination plant that desalinates ocean water. A water gate of the desalination plant is opened to allow salt water from an ocean to flow into an isolated salt water zone. Once desired amount of salt water enters the desalination plant, the water gate is closed to prevent both further salt water from flowing into and the isolated salt water from flowing out of the isolated salt water zone. An isolation wall prevents the isolated salt water from flowing into a desalted water zone. The isolated salt water in the isolated salt water zone is heated by using sunlight and electric heating elements to be vaporized. The sunlight entering the isolated salt water zone is reflected on multiple reflective surface to further heat the isolated salt water. The vaporized water flows towards the desalted water zone, and subsequently cools down to condense into desalted water. The desalted water in the desalted water zone flows through an exit pipe and is collected at a reservoir.

A unique adaptive method of Mechanical Vapor Re-compression (MVR) to dehydrate abrasive sludge to a dry, sterile state that is nearly moisture free while maintaining extremely high process efficiencies by adaptively tuning the system parameters related to the varying specific plus latent heats of the input feedstream. This Adaptive MVR (AMVR) process is supported by the effective use of a unique method and apparatus for the optimization of the conductive heating process as applied to a range of sludge consistencies.

A contaminated medium (such as soil and/or groundwater) contaminated with petrogenic and/or other organic contaminants such as petroleum hydrocarbons, light non- aqueous phase liquids (NAPLs), dense non-aqueous phase liquids (DNAPLs), persistent organic pollutants (i.e. sulfolane), chlorinated compounds, and volatile organic compounds, can be mixed with enhanced stimulators and be thermally remediated. The enhanced stimulators are heat induced to undergo exothermic reactions, which initiate a series of in-situ chemical reactions to such as to produce hydrogen gas. The hydrogen gas causes hydrocracking of heavy hydrocarbons to produce light hydrocarbons which can be recovered such as for future use.

Embodiments relate to systems and methods directed towards arrangements of a preheater, a heat exchanger, a plasma recovery system, and at least one processing stage configured to use steam output of a calciner for heating incoming wastewater that is being processed.

A liquid separation system includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas.

A device for evaporating a liquid such as liquid fuel. The device comprises: a shell; means for supplying heat to the shell; a porous wick located in the shell so that there is a gap between an outer surface side of the porous wick and an inner surface of the shell; means for supplying liquid to the porous wick; and an outlet in the shell for vapour produced in the gap by the application of heat from the shell to the liquid in the wick.

Volatile compound emissions from a product that comprises a polymeric material may be reduced or eliminated from the product by heating the product in a subatmospheric pressure environment. The product may be heated in the subatmospheric pressure environment at a temperature sufficient to vaporize a volatile compound contained within the polymeric material such that vapors of the volatile compound are extracted or released from the product.
