 in the current desalter configurations may cause poor desalting (salt removal) efficiency due to solids build up at the bottom of the vessel, and/or a solids stabilized rag layer leading to erratic level control and insufficient residence time for proper water/oil separation. Solids stabilized emulsion layers have become a major desalter operating concern, generating desalter upsets, increased preheat train fouling, and deteriorating quality of the brine effluent and disruption of the operation of the downstream wastewater treatment facilities.
While none of the current desalter configurations have the capability to remove the emulsion layer for treatment and reintroduction into the refinery, US 2012/0024758 (Love) proposes a technique in which the thickness of the emulsion “rag” layer is withdrawn from the separator vessel at a rate that maintains the height of the emulsion layer approximately constant so as to permit withdrawal of the rag layer at a fixed level from the vessel. The withdrawn emulsion is then processed outside the vessel through a stacked disk centrifuge. While this method has the advantage of handling the troublesome rag layer so as to maintain proper functioning of the separator, it is not optimally adapted to continuous desalter operation since it requires the fixed location of the emulsion layer to be determined by existing techniques such as those described briefly above. For this reason, use of the method may be uncertain, time-consuming or expensive and, in the event of changes in crude composition, problematical as a result of variations in the thickness or position of the emulsion layer which cannot be readily accommodated Consumers are frequently seeking to style their scalp or facial hair, for example to provide a certain hairstyle for their scalp hair or, in other cases, style their eyebrows or, in the case of male persons, their beards, moustaches and/or sideburns, by decorating them and, once styled, it is desirable that the hair remains held in the styled position, or conserves a decorated condition. After styling, there is a tendency for hair to return from its styled to its unstyled condition. For example, hair may return to its natural shape if moistened or under high humidity conditions. Therefore, there is a need to provide hair products that retain hair in a styled condition.
