Abstract: In example embodiments, a system and method for keeping calls connected are provided. A call is initiated between a first user device and a second user device each of which has a connection application for maintaining communications. A call maintenance option provided by the connection application is activated on the first and second user devices. A determination is made that one of the first user device or the second user device is a call manager, whereby the call manager is responsible for reinitiating the call in response to the call being dropped. Detection that the call is dropped is made. In response to the detection that the call is dropped, the call manager reinitiates the call while the non-call manager waits in a standby mode for the reinitiation of the call.

Abstract: Disclosed herein are systems and methods for automated real-time monitoring and controlling desalting in a crude distillation unit. Crude oil and wash water are mixed by a pressure drop across a mix valve, thereby forming a crude oil/water phase stream. The crude oil/water phase stream is supplied into a desalter vessel, whereupon an emulsion forms at an interface between the crude oil and the water phase. The crude oil/water phase stream is contacted with a dosage of an emulsion breaker in an applied electric field. At least one property associated with the emulsion is measured using an emulsion level indicator. A total chlorine and a water percentage of the crude oil are measured. At least one of the pressure drop and the dosage of the emulsion breaker is adjusted substantially in real time in response to at least one of the measured properties, total chlorine, and water percentage.
