Phase separation Process Equipment

Phase Separator Equipments

Different kinds of phase separator equipment are used in the process industry. Read more about their types, structures, functioning and general principles.

Demister Pads - The demister pads work by coalescing smaller liquid droplets by obstructing their path. Obstruction of path causes increased collisions among the liquid droplets. Most of these droplets stick together and form bigger droplets which are too heavy to rise with the gas stream. Thus the bigger liquid drops drop down in the pool of liquid below.

Mechanical Steam Drums - High capacity, high pressure (HP) boilers, steam-water separation at the steam drum is accomplished with the use of mechanical steam-water separators. With the installation of these devices in the steam drum, the drum’s diameter and cost can be significantly decreased.

Phase sepration equipment calculators - Calculators for sizing gas liquid separators such as knock out drums or degassers, Separator vessel volume calculators etc.

Schoepentoeters - Schoepentoeter inlet devices are used in phase separator vessels as well as stripper, absorber, distillation columns etc. mainly for even distribution of the inlet flow across the vessel or column cross sections. Even distribution of the fluids across the cross section geometries becomes important in order to minimize the channeling of these fluids, which can lead to reduced equipment efficiency.

Spiral flow type gas liquid separator internal - A ‘spiral flow type cyclone device’ is a filtering device used for separating solid particles or liquid droplets from gas flow. These devices are typically used in two phase separators at the gas outlet, to enhance the overall separation efficiency of the equipment. The structure of spiral flow internal devices do not need the gas to change the main flow direction, unlike in the conventional type cyclone separators.

Typical P&ID arrangement for separator vessels - Typical P&ID arrangemet for separator vessels is presented along with the generally used instrumentation and controls system, relief devices for the vessel, inlet-outlet and instrument nozzles, drains, vents, isolation arrangements, special internals on the separator vessel etc. General requirements of these devices when designing a separator vessel system are described.
