A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.

An electrostatic air precipitator for emission remediation including, a grounded frame connected to a housing having an upstream direction and a downstream direction with a first ionizing section, having at least a first set of ionizing members and a second set of ionizing members, where the ionizing members of the first set and the second set are electrically isolated from each other and electrically isolated from the grounded frame. Also, the ionizing members of the first set and the ionizing members of the second set are powered by separate power supplies and at least a first collector section is located downstream of the first ionizing section, and the first collector section has at least a first plurality of collector plates.

A method for purifying and cooling biomass syngas. The method includes: 1) cooling biomass syngas to 520-580 C., and recycling waste heat to yield a first steam; then subjecting the biomass syngas to cyclone dust removal treatment; and further cooling the biomass syngas to a temperature of 210 C., and recycling waste heat to yield a second steam; 2) removing a portion of heavy tar precipitating out of the biomass syngas during the second-stage indirect heat exchange; 3) carrying out dust removal and cooling using a scrub solution, to scrub off most of dust, tar droplets, and water soluble gases from the biomass syngas after the heat exchange and dust removing treatment; and 4) conducting deep removal of dust and tar with a wet gas stream, to sweep off remains of dust and tar fog in the scrubbed biomass syngas.

In an air conditioner, an upper heat exchanger and a lower heat exchanger exchange heat between air and a refrigerant. An air cleaner includes a charging unit for charging particles in the air and a dust collecting unit for collecting the particles charged by the charging unit by an electrostatic force. An indoor unit body houses the upper heat exchanger and the lower heat exchanger and houses the air cleaner of which the center position in the height direction is positioned lower than a connection part between the upper heat exchanger and the lower heat exchanger.

Beneficiating particulate additives by removing contaminants or minerals that impact the quality and specific gravity of the particulate additives may be achieved via dry solids separation technologies. For example, an air classifier, an electrostatic separator, and a combination thereof may be used to produce a beneficiated particulate additive comprising less than 40% of drill solids by weight of the beneficiated particulate additive.
