The present disclosure provides methods and apparati for separating liquids from production gases and recovering the liquids. The methods and apparati of the present disclosure can reduce or eliminate emissions compared to standard methods and devices and also eliminate the need for haul away of liquids by collecting compressor system liquids in charge vessel(s). The methods and apparati of the present disclosure can also be used to fuel the engines which operate the compressor systems using gas from the compressor drains and the gas used to drain the charge vessel(s).

An oil separator includes a housing into which mixed gas in which unburned gas and engine oil are mixed with each other is introduced from a crank case; a centrifuge mounted in the housing and generating centrifugal force to the mixed gas to thereby separate the engine oil from the mixed gas; and a filter separator mounted in the housing and filtering the engine oil in the mixed gas. Since the engine oil is primarily separated through the centrifuge and secondarily separated through the filter separator, engine oil separation efficiency is improved as compared to the related art, and the same amount of gas may be treated even with a small size as compared to the related art.

A gas scrubber cone condition monitoring system has a sealed gas scrubber cone (9) moveably mounted in a gas pipe (1), a collar (5) fixedly mounted radially outward of the cone in the gas pipe and a pressure tap (12) into the sealed cone. The pressure tap is coupled to a condition monitor (17,18) via an input line (16). An output line (14) from the condition monitor is coupled to a gas pipe (15), downstream of the sealed cone. The condition monitor includes at least one of a pressure gauge and a gas flow meter.

A chlorine bypass device which can cool exhaust gas quickly by mixing extracted exhaust gas with cooling air at high efficiency, to thereby produce fine chloride dust, and increase dust recovery efficiency.

An exhaust gas purification apparatus for an internal combustion engine, capable of carrying out oxidation removal of PM deposited in a filter as a whole in an efficient manner, includes a filter arranged in an exhaust passage of the internal combustion engine and having an oxidation catalyst supported in at least an upstream side portion thereof, and a heating device arranged so as to be able to heat the upstream side portion of the filter irrespective of oxidation reaction heat of the oxidation catalyst, wherein when filter upstream regeneration processing to oxidize and remove deposition PM in the upstream side portion of the filter is carried out by controlling a heating device, an amount of decrease of the upstream side deposition PM by the filter upstream regeneration processing is reflected on an amount of filter PM deposition in the ordinary filter regeneration processing which oxidizes and removes the deposition PM in the entire filter by means of oxidation reaction heat of unburnt fuel generated by the oxidation catalyst supported in the filter, and the filter upstream regeneration processing is ended, even if the thus reflected amount of filter PM deposition is in a state of being larger than a reference amount of deposition which is a threshold value for ending the ordinary filter regeneration processing.

An air filter arrangement for use in a truck pneumatic product transfer system using a generally rectangular housing and two air filter cartridges to alter the shape thereof (primarily reduce the width thereof) allowing the unit to be mounted centrally behind a truck cab or in other locations. The design and shape allows mounting on the truck in preferred areas that are less utilized for accessory equipment and can increase truck aerodynamics. Additionally the filter arrangement can reduce overall truck weight compared to traditional units.

A separator for a gas stream has a horizontal tank with a fluid inlet, a fluid outlet and a flow path along the inside of the horizontal tank. A flow barrier is disposed within the tank between the inlet and the outlet. One or more sets of liquid ports are in fluid communication with the tank and positioned at a bottom surface of the tank. Each set of liquid outlets has a first port and a second port. The first port is positioned upstream along the flow path relative to the second port. A fluid passage is in fluid communication with the first port and the second port. The fluid passage defines a secondary flow path adjacent to the horizontal tank, where the first port acts as a draft inlet to the secondary flow path and the second port acts as a draft outlet from the secondary flow path to the tank.

A device for separating liquid from a gas stream within a liquid injected compressor, said device including a first vessel including a first bottom plate, a first lateral wall comprising an inlet fluidly connected with a compressed gas outlet and a lid including an outlet, the device further including: a first separation means; a second separation means; and a third separation means; whereby the device further includes an inlet channel being in fluid communication with said inlet, said inlet channel including a top panel and a bottom panel, whereby at least said top panel is creating a slope, having the highest point onto the first lateral wall and the lowest point at the opposite end.
