Q. How much sandy gas can a 16" x 8' x 6000# sand trap clean per day? A. Depending upon the amount of sand entrained in the stream and the average operating pressure, a 16" x 8' x 6000# unit can produce anywhere from 7mm scf/d to 10mm scf/d. Q. What size is the Inlet and the Gas Out and Sand Discharges? A. 6,000#, 5,000# and 3,000# sand traps have a 2" inlet configured with a male threaded 1502, gas and sand discharge outlets have 2" 1502 female hammer halves.	16" x 8' x 6000# Sand Trap
Sand Trap mated to a 3 phase Test Separator	Q. What happens when liquid goes into the sand trap? A. Sand in a high pressure gas stream is one of the most abrasive things known. It is so effective that an entire industry has evolved to take advantage of the abrasive power. But, for the oil & gas industry, this same abrasiveness spells destruction for downstream equipment, valves and pipelines. Sand separators remove sand by slowing down the gas flow and allowing the heavy sand to drop to bottom of the vessel... that's why sand traps are vertically oriented. When liquid is encountered, the entrained sand is buffered in the liquid and does not separate out effectively. This buffering effect protects downstream components from the sand's abrasiveness. Liquid-entrained sand commonly causes test separators to "sand off", but does little damage to chokes, pipes and valves. Most test separators have manways or oversized inspection ports or drains to facilitate sand removal. As the flow from a new well becomes drier, the sand becomes more and more abrasive, and a larger threat to effective testing and production.
Q. Should I put the sand trap before or after my choke manifold? A. A Choke manifold benefits when placed downstream of the sand trap since it is not exposed to the abrasive sand. However, there are times when it is necessary to place a choke manifold upstream of the sand trap. The most common reason is that the pressure at the wellhead is higher than the sand separator rating and must be reduced. Another reason is that the new well is producing mostly liquid and the manifold is used to shunt the liquid directly to holding tanks. As the flow from the well dries out, the manifold makes it easy to change the flow from tanks to sand trap, and from there, into the Test Separator.	Choke Manifold
Sand Trap + 2 Phase Separator DualPack	Q. Is there a dedicated sand trap + 2 phase separator unit available? A. Yes, they are commonly knows as "DualPack" units. A DualPack is a 24" x 10' x 1440# sand trap mated to a 24" x 10' x 1440# 2 phase vertical separator and mounted on an "L" skid for easy transport. DualPacks are popular in gas fields where a significant amount of sand and moisture is present in the gas. Used mostly for production, a DualPack is a low cost, highly portable solution. We build DualPacks to order using surplus vessels allowing us to keep costs down, while being able to fulfill orders quickly.
