36results about How to "Improve oil separation" patented technology

A method is provided for the use of a chemical additive to improve the separation of oil from the process stream (whole stillage, thin stillage or syrup) generated as a byproduct in corn to ethanol production.

Methods and systems are provided for generating vacuum from crankcase ventilation flow. During both directions of gas flow between an engine intake manifold and a crankcase, gases are directed through one or more aspirators to produce vacuum. The drawn vacuum may then be used to operate various engine vacuum actuators.

The improved methods relate to desalting hydrocarbon feeds using a separator with a stacked disk centrifuge to separate an emulsified oil and water rag layer. This method is effective for desalting heavy, high ionic, and non-traditional crude oils.

A polymer activation assembly is provided for separating monomer from the oil in which it is suspended in a polymer forming suspension and mixing the monomer with water supplied from another stream. The supply water is supplied through a primary fluid channel extending through the activation assembly and which transitions to a relatively wide rectangular activation channel. A secondary fluid inlet is formed in a side of the activation assembly for injection of the polymer forming suspension therein. A nozzle section of the secondary fluid inlet is formed between an initial section of the inlet and the activation channel. The nozzle section is generally rectangular in cross section and relatively shallow. The distal end of the nozzle section has a width that approximates the width of the activation channel. The nozzle section angles at an acute angle toward the outlet.

The invention discloses a centrifugal fan volute for a smoke ventilator. The centrifugal fan volute comprises an annular wall and an air outlet formed in the periphery of the annular wall. The annular wall comprises an inner annular wall and an outer annular wall, and a cooling circulation channel is formed between the inner annular wall and the outer annular wall. A plurality of baffles are arranged in the air outlet at intervals; the air outlet is divided by the baffles for forming at least one main airflow channel; the baffles are hollow and are provided with cooling parts; two ends of each baffle communicate with the end part, adjacent to the air outlet, of the cooling circulation channel, so that a closed fluid path is formed by the baffles and the cooling circulation channel. A channel for flow circulation is formed in the annular wall of the volute; the temperature of the annular wall of the volute is reduced; and the temperature difference between smoke and the annular wall of the volute is increased, so that the amount of smoke intercepted by the annular wall is improved; the fat separation degree of the smoke ventilator is improved; the smoke discharging amount of the smoke ventilator is lowered; and the air pollution is reduced. The interception process does not cause resistance to the air flow, so that the volume of air through the volute is ensured.

A petroleum desalting process is improved by introducing the an alkaline compound such as sodium carbonate into the water phase, preferably in the vicinity of the water / oil interface which forms between the oil and water layers. This makes the rapid and effective separation of the oil and water phases from the emulsion layer possible.

The invention discloses a high voltage static module for oil fume separation and a range hood provided with the high voltage static module. The high voltage static module comprises a static electrode and a collector; oil fume channels are formed in an insulation outer frame of the static electrode; a plurality of needle electrodes and a plurality of counter electrodes that are mutually electrically isolated are arranged in the insulation outer frame, and stretch along the oil fume channels; the needle electrodes and the counter electrodes are arranged in a mutually staggered manner; ionization space is formed between the adjacent needle electrodes and counter electrodes; each needle electrode comprises connecting rods and a plurality of conduction needles arranged along the connecting rods in a spaced manner; the conduction needles are connected with the connecting rods, and stretch along the oil fume channels; and the collector is used for collecting oil fume particles which are live in the oil fume channels and flow into the collection space. According to the high voltage static module for the oil fume separation, the separation degree of oil in oil fume can be raised, the accumulation of the oil fume in a fan duct is reduced, and the service life of the range hood is prolonged.
