Provided are a vacuum rectification tower with a satellite-type tower kettle and a vacuum rectification method for atmospheric pressure residual oil. The vacuum rectification tower includes a satellite-surrounded vacuum tower kettle and a rectifying section; the satellite-surrounded vacuum tower kettle includes a main tower kettle and a plurality of sub-reactors arranged outside the main tower kettle in a satellite-surrounded mode; the main tower kettle is provided with a first outlet and a plurality of spray inlets, and a top portion of the main tower kettle has an opening; the sub-reactor is provided with a second outlet and a first inlet, the spray inlets are connected with the second outlets of each sub-reactor in a one-to-one correspondence, and the first outlet is connected with the first inlets. The above vacuum rectification tower is used for treating the atmospheric pressure residual oil, and an extraction rate of light oil may be effectively improved under relatively mild temperature and pressure environment.

An apparatus for extracting contaminants from a contaminated material, such as contaminated soil and animal manure, includes an extraction tank having an interior, a heating element that is adapted heat the contaminated material to a temperature where contaminants in the contaminated material are released therefrom to the interior of the extraction tank, and an agitator that is adapted to agitate the contaminated material as it is being heated by the heating element. The apparatus also includes an air pump that generates a series of positive pressure air pulses at an outlet thereof and a series of negative pressure air pulses at the inlet thereof. The apparatus further includes one or more contaminant retaining mechanisms, such as a sediment holding tank, a fluid holding tank, and a gas filter. The interior of the extraction tank, the air pump, and the contaminant retaining mechanisms are connected in a closed loop air circulation system such that the contaminants that are released from the contaminated material are stored in the contaminant retaining mechanisms.

A thermal utilization plant including a heat engine and a cooling system for the heat engine. The heat engine is operable to receive heat from a non-carbon heat source (carbon heat source can be used) and to transfer heat to the cooling system. The cooling system includes an evaporator configured to vaporize a working fluid to a vapor state. A condenser is coupled to the evaporator by a conduit and operable to receive the working fluid in the vapor state and to condense the working fluid to a fluid state. An output is coupled to the condenser and operable to receive the working fluid from the condenser and to provide the working fluid for beneficial use.

A method and system of and for extraction or removal of phytochemicals from plants, including those of the plant family Cannabaceae. More specifically, a method and system for extracting essential oils from plants, such as cannabis, without the use of a solvent.

The present invention relates to a device and also to a method for separating and recovering a cyclic diester, in particular dilactide or glycolide from polymer melts which include the cyclic diester as impurity. The device and also the method according to the invention allow recovery of the cyclic diester with a high yield and at the same time high purity.

A method for distilling a fluid includes moving a fluid to be distilled into a distilling column. A motive fluid is pumped into a liquid-driven gas ejector. Gas from a vapor outlet of the distilling column is discharged into a gas inlet of the ejector. Fluid is conducted from an outlet of the ejector into a heat exchanger. Heat from fluid conducted from the ejector is transferred to at least one of the fluid moved into the distilling column and an interior of the distilling column.
