Abstract: Methods have been developed for removing valuable liquid condensates from natural gas streams, which in certain embodiments do not use pumps and which are operated by the input pressure of gas to be processed. In other methods according to this invention pumps and equipment with moving parts are used. In one aspect a method described here includes: cooling input gas to a desired level to form a mist in the gas of condensed droplets of desired size, e.g., but not limited to, droplets of a largest dimension of at least 0.1 micrometer, 0.7 micrometer, or less than 1.0 micrometer; based on an analysis of the condensates, selecting a desired microfilter media to filter liquid condensates from the cooled gas; and filtering the cooled gas producing a liquid condensate(s) stream and a gas stream, each of which may be usable as fuel or in other methods or apparatuses. A gas collector has been developed to collect all or substantially all of the condensates from a gas sample, e.g.
