A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

A process for synthesis of urea from CO.sub.2 and NH.sub.3 wherein a steam flow (13) produced in the condenser (3) of a high-pressure synthesis loop is compressed to raise its pressure and temperature before using the steam as a heat source for a downstream step of the process.

A device for inspecting a surface of an object, in particular a reflective or transparent surface, including an illuminating apparatus with which the surface can be illuminated, a measuring apparatus which senses light reflected at the surface, and a vapor-application apparatus which is designed to apply vapor to the surface. To achieve an efficient application of vapor, it is provided that the vapor-application apparatus includes a nozzle, a vaporization chamber having an enclosure, and a heating apparatus. The nozzle protrudes into the vaporization chamber in order to introduce a liquid into the vaporization chamber, and the vaporization chamber includes a vapor outlet.

The current disclosure provides a method to improve the performance of evaporators and condensers by maintaining the vapor velocities on the heat exchange surfaces within a desired range. This is accomplished by providing a constant or tapered narrow gap for vapor flow in the heat exchangers. The shear induced by the vapor over the heat exchanger improves the evaporator performance by disturbing the liquid film flowing over the heat transfer surface. In the condenser, the vapor shear helps to remove the condensate in the form of film and droplets, and also removes the non-condensable gases from the heat transfer surfaces as the vapor condenses out and increases the concentration of the non-condensable gases over the heat transfer surfaces. Parameters identified include minimum gap and the taper angle between the cover plate and heat transfer surface.

Concentrated creams are produced from starting cream compositions characterized as homogenous, oil-in-water emulsions containing fat globules, phospholipid membrane components and non-fat solids, and which have an initial fat content between about 35 to about 55 percent by weight. To produce the concentrated creams, moisture is removed from the starting cream compositions through evaporative processing, and as a result, the concentrated cream remains in a homogenous state, retains the fat globules, phospholipid membrane components and non-fat solids, and includes a concentrated fat content of at least about 70 percent by weight. In addition, the concentrated cream may be in an oil-in-water or a bi-continuous emulsion. Evaporative processing may be through a wiped film evaporator or a scraped surface heat exchanger.

The invention relates to a disinfection method to be used for cleaning. The invention is characterized in that hydrogen peroxide (H.sub.2O.sub.2) is drained/transferred from one or more tanks (16) by a liquid pressure created by one or more pumps or gravity, through one or more draining pipes (6) to one or more draining devices (5), which draining device (5) drains hydrogen peroxide to one or more onto one or more evaporation top surfaces (4ea) of an evaporation member (4e) of a warming/heating device (4), the evaporation top surface (4ea) is at an evaporation angle (4ej) of 1 to 30 degrees in relation to the horizontal plane so that the end on the draining device (5) side draining end (4c) is higher than a gas discharge end (4d) at the opposite end of the draining device (5) of the warming/heating device (4), whereby hydrogen peroxide spreads by gravity on the evaporation

A process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in cannabis oil reacts with acetic anhydride under reflux to produce THC-O-acetate and acetic acid. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.
