The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mixing device of the desalter system. This is achieved by using a first principles based model combined with a sensor to measure the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through direct measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.

Advisory controls of desalter system

An injection quill design and methods of use for injecting a first fluid into a second fluid. The injection quill may comprise a hollow stem having a closed end and a sidewall, the stem having a curved cross-section defined by a major axis, and a minor axis, and at least one orifice for injecting the first fluid into the second fluid, wherein the major axis is greater than the minor axis and/or the orifice extends through the sidewall and/or the orifice has an internal chamfer with a chamfer angle ranging from less than 0&#xb0; but greater than 90&#xb0;.

Injection quill designs and methods of use

The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mix valve of the desalter system. This is achieved by using a first principles based model combined with an ultra-sound sensor. The ultra-sound sensor measures the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through ultrasound measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.
