New Gas Filtration Update

Filter Facts by TM Filtration

picThe Filter housings are sized based on the gas flow rate. As the gas enters, the liquid molecules start to lose velocity and start bonding with other liquid molecules and this turns them into droplets. As the droplets become bigger and heavier, the droplets fall to the bottom of the filter. By the time the gas reaches the Coalescing Layer, 99% of all liquids greater than 10 micron have been removed. As the gas molecules enter the area of the Gas Coalescing Filter and because of the pleated filter design, the radial velocity is designed to be less than 0.3 feet per second.

Note: Vapor Velocity is defined as the point where gravity overcomes the liquid weight/speed. Radial Velocity is defined as the striking velocity that the gas meets the surface of the area of the filter element.

Due to the layered design structure of the TM Filtration coalescing gas filter, the gas flows through the first layer which removes 99.9% of all debris materials and starts the liquid coalescing process. The middle layer is the micro borosilicate glass which accumulates all liquid microns which turns in to particle sizes. Particle sizes collect together and become droplets that flow downward by gravity. The third layer is a polishing layer in case any particles make it through the first two layers.

Where in the hollow interior core as defined as the polymeric layer tube is in direct communication with the dry gas outlet. This inter tube is designed like an RO Filter that will only let dry gas down to 1 micron pass through (Rated at 0.3 micron for liquids).

(This process design is covered in U.S. patent number 7,332,010 B2 and Canadian patent number 2,426,752).






Gas Flow Membrane Technology

Electric Power consumption at Natural Gas Drilling sites on both the Marcellus and Utica Shale plays, has been in the news lately; specifically getting power to remote areas to run the equipment. A need for natural gas microturbines and gas driven engines is emerging from the shale gas market. The problem we see is what is coming out of the well heads with the natural gas: debris and liquids that need to be removed.

TM Filtration’s engineering staff has developed a new design (from 2” thru 12” pipe line sizes) Bulk Deliquidizer/Desander Coalescer (patent pending). This unit can be modified to meet the needs of each well site. One piece of equipment will remove any debris from the well site (including fracking sand) and remove any liquids down to 0.3 Micron at 99.9%. The final filtration uses our GFM Technology®.

pic3Unit Operation: The wet gas separates from the liquid condensate and the sand settles in a compartment in the bottom of the receiver. The wet gas then flows through the separator and then enters the vertical tower that houses the vane separator. The separator then removes all liquids down to 10 micron. The gas coalescing filter then only needs to remove the balance (10 micron and smaller) extending the life of the GFM Technology® gas coalescing filter. Parts of this new design is covered Under USA patents 7,332,010 B2, 7,850,751 B2 and Canadian Patent 2,426,752.
