A flow stream filtering method and system

A filter system operating under vacuum conditions, comprising:

• a flow stream input section, connected to a source of flow stream;
• a filter section connected to said flow stream input section;
• and
• a flow stream output section connected with said filter section;
• wherein said flow stream input section receives, at a flow stream inlet port thereof, from said source of flow stream, a flow stream comprising at least one of air, water, airborne droplets, moisture and gases, and directs the flow stream to said filter section, and from said filter section to said flow stream output section, the system delivering a filtered flow stream from said flow stream output section at a flow stream output thereof;
• wherein said filter section comprises filter elements, a number and a size of the filter elements being selected to optimize a flow stream volume within the filter section and a contact surface between the flow stream and surfaces of the filter elements, and to optimize flow of a liquid phase along the surfaces of the filter elements;
• the filter elements capture a liquid phase from the flow stream, and direct the liquid phase from the filter section to the flow stream input section, the flow stream input section directing the liquid phase out of the system at a liquid output thereof.
