Natural gas, during the production, transportation and distribution processes, besides containing solids circulating in the flow, also has liquids in several phases, which also cause equipment damagesSuch liquid contaminants are lubricant oil, water, condensed material, amines, glycol,corrosion inhibitors and/or a mix of these products.

Retention or separation of fine liquids and solids contained in natural gas requires a specific technology matching inertial impactation processes, when the flow direction changes due to barriers resulting from the filtering element or filter geometry, and diffusional interception, which retains and glues liquid particles, to later separate them by gravity.

The filter and element drainage speed control optimizes the filter and separation efficiency.

The horizontal and vertical Gascat coalescent filters have filtering elements that gather the above-mentioned techniques, allowing for great operation functionality, and include design details that enable quick and complete drainage of the coalesced contaminants.

The perfect balance among filter size, element number, element type and drainage speed will enable filtering of 99.98% of the particles greater than 1 micron.

The quick opening system, requiring one single operator, allows for easy servicing, offering significant savings in stoppages for cleaning and replacement of the filtering elements The equipment may be supplied with instruments, meters, gauges and valves, which will ensure a fully automated and safe liquid drainage
