separator 18 sand separator also known as a sand trap 18 receives flow from production line 16 sand separator 18 has a fluid outlet 20 and a solids outlet which is attached to sand dump line 22 the fluid outlet 20 is connected to a choke manifold 24 which is a system of valves and chokes for controlling the flow from the well 10 flow from choke manifold 24 is thereafter routed through choke outlet 26 the flow through choke outlet 26 by the appropriate valving may be directed into test separator 28 which will return liquids back into the fluid outlet 20 and separated gas into the gas discharge system both choke outlet 26 and sand dump line 22 are connected to closed separator 30 closed separator 30 is a largely self contained unit which allows an operator to make the necessary connections and obtain a unit which receives a solids laden fluid separates the gas liquids and solids and has a self contained cleaning system closed separator 30 is packaged to be compact unit having a relatively small footprint and to be transportable by truck rail or boat closed separator 30 contains the vapors and volatile organic compounds contained within the received fluids and discharges these substances for further processing and incineration or sales closed separator 30 receives flow from choked outlet 26 through a first inlet 32 closed separator 30 receives flow from sand dump line 22 through a second inlet 34 closed separator.
