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.
