A coalescer is a device which induces coalescence in a medium. They are primarily used to separate emulsions into their components via various processes, operating in reverse to an emulsifier . Coalescers are of two main types: mechanical and electrostatic.
With the plate packs, water is fed into the separator through gravity through the inlet pipe, then the mixture is spread evenly through the separation chamber where the coalescing plate packs are. In the plate packs the oil will rise because of their buoyancy and coalesce on the underside of the plates and form globules of oil that rise to the ...
A gravity plate separator contains a series of plates through which the contaminated water flows. The objective of the design is to allow oil droplets in the water to coalesce on the underside of the plate eventually forming larger oil droplets which floats off the plates and accumulates at the top of the chamber.
Baking ovens – Combines the function of curing and drying ovens. Reflow Ovens – A reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCB). A graphical example of a convection reflow oven. The oven contains multiple zones, which can be individually controlled for ...
Coalescing plate separators may not be effective in situation where water chemicals or suspended solids restrict or prevent oil droplets coalesce. In operation it is intended that sediment will slide down the topside of each parallel plate, however in many practical situations the sediment can adhere to the plates requiring periodic removal and ...
Electrodynamic droplet deformation also of particular interest in crude oil processing as a method to improve the separation rate of water and salts from the bulk. In its unprocessed form, crude oil cannot be used directly in industrial processes because the presence of salts can corrode heat exchangers and distillation equipment. To avoid ...

A decanter centrifuge applies a force equivalent to several thousand G's, which reduces the settling time of the particles. It is also favoured to maintain a large G-force, which will result in an improved separation. [8] The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process.
