Inlet Devices

The design features of the upstream piping, the inlet nozzle and the inlet device, have a strong influence on the overall performance of the separation system. For the most efficient separation processes, an even distribution of the flow over the inlet face of equipment is essential. In the case of gas/liquid separation, this uniformity helps to minimise liquid carryover, which is normally associated with mal-distribution of the flow at the inlet to the demisting equipment. For liquid/liquid separation, uniformity of the flow minimises any mixing before the fluid enters subsequent stages of the coalescing and separation equipment.

Many different types of inlet device are available for insertion into separator vessels, each having its own operational parameters, advantages and operational efficiency. Historically, the most common types have been "deflector plates", "simple baffle type" devices, "inverted dished heads", "pall ring boxes" and "half open pipes", although many other systems are described in the literature. Today, however, an increasing number of contractors and operators are moving away from these traditional types of inlet device towards more advanced designs, as understanding of the importance of correctly designed inlet devices and the limitations of the different systems grows.

Advanced Petro Gas Process Co., Ltd. offers a full range of the more traditional inlet devices and advanced inlet devices.
