When rigging up to flow back a gas well does the sand trap get rigged up before the manifold?

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.
