Compressor crankcase oil reclamation methods and systems include a coalescence filter coupled to a pressure relief vent of a compressor crankcase. The filter separates oil from an oil/gas mixture exiting the crankcase. A reservoir receives the oil so-separated. A valve restricts flow of the oil so-separated to a single flow direction running from the reservoir to the crankcase.

A liquid storage tank has a breathing valve that vents the tank's headspace at a high-pressure value and admits an ambient gas at a low-pressure value. A controller generates a first control signal when the percentage of the catalyst gas is less than a catalyst threshold, a second control signal when the percentage of the catalyst gas exceeds the catalyst threshold, and a third control signal when the pressure in the headspace is equal to a low-pressure threshold between the breathing valve's low-pressure value and high-pressure value. The first valve is only opened to output inert gas at a discharge pressure greater than the breathing valve's high-pressure value in response to the second control signal. The second valve is only opened to output inert gas at a discharge pressure that is between the breathing valve's low-pressure value and high-pressure value in response to the third control signal.

Liquid storage tank protection system and method

A air shroud for cylinder and cylinder head assemblies of air-cooled compressors and engines of the type having a cooling air fan for producing an axial flow of cooling air and an array of cylinder and cylinder head assemblies arranged in the path of the axial flow and extending radially relative to the axis of said flow. In particular, the shroud has a flow channel portion of a polygonal segment shape which wraps around the periphery of the array of cylinder and cylinder head assemblies and forms an air channel from the cooling air fan to the cylinder and cylinder head assemblies and which is fastened atop each of the cylinder and cylinder head assemblies. In order to increase the quantity and rate of flow of cooling air over the cylinder and cylinder head assemblies while increasing the surface area of the assemblies washed by the cooling air, fins are provided depending from the flow channel portion of the shroud at a point between 50 to 90% of the distance across the cylinder and cylinder head assemblies viewed in the airflow direction, each of the fins blocking an open area between adjacent cylinder and cylinder head assemblies in a manner creating an airflow orifice gap about its perimeter between the fin and the adjcent cylinder and cylinder head assemblies.
