The present invention relates to a pressure-controlled oil refining device for refining oil from liquid-state oil waste. The purpose of the present invention is to provide a pressure-controlled oil refining device wherein: liquid-state oil waste is introduced and then heated such that, as the pressure rises, the vaporized fluid (oil+impurities) is transferred in the upward direction; a pressure valve is opened/closed such that the oil and impurities can be separated from the fluid and then discharged; the oil is condensed by a cooler such that the same can be liquefied again and stored; and the oil can be refined from the oil waste and reused.

A method for preventing blockage of a cryogenic injection system is disclosed. The cryogenic injection system is provided comprising a gas feed line attached to a gas distributor. A gas is fed through the gas feed line and the gas distributor into a cryogenic liquid. A portion of the gas feed line passes through the cryogenic liquid. An insulative layer is provided for the portion of the gas feed line that passes through the cryogenic liquid. Heat transfer through the insulative layer between the portion of the gas feed line and the cryogenic liquid is countered sufficiently to prevent blockage of the gas feed line by a component or components of the gas. In this manner, blockage of the cryogenic injection system is prevented.

The present invention is related to a solar driven irrigation apparatus for converting contaminated water contained in a contaminated water body into distilled water and using said distilled water for irrigating the vegetation grown on the said irrigation apparatus, the solar driven irrigation apparatus comprising a cover in the form of a geometrical projection comprising a wall, an opening, a semi-permeable mesh, a soil layer and a chamber. The present invention also related to a process for irrigating natural vegetation using the solar driven irrigation apparatus.

Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. ?5? C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step series of concentrator devices, such as zeolite concentrator devices. One or more emission control operations can be carried out downstream of the single or multi-step concentrators. The aforementioned condensing process enables the one or more concentrators to operate in a favorable temperature range for removal of 99% or more of VOC, thereby meeting or exceeding strict environmental regulations.

Provided are urea manufacturing method and apparatus, which can increase the conversion ratio into urea and to reduce the consumption of steam. The temperature of the reactor is increased by introducing the entire amount of raw material ammonia and introducing a portion of the decomposed gas from the stripper into the reactor. The raw material ammonia is preferably heated using the steam condensate generated in the purification step, and/or the steam generated by the heat of condensation of the decomposed gas and the unreacted substances in the condensation step. The heating temperature is preferably between 70 and 140 C.
