Gasoline In-Line Blending

In-line blending is the continuous mixing together of two or more different component streams in order to obtain a final product of closely defined proportions. It is considered more economic than batch blending method. It saves money by blending faster, requiring less manpower and storage facilities and by reducing the quality giveaway.

The in-line blending system (ILB)  has installed enough legs to add all components simultaneously. Each leg contains a flow control loop with high precision flow meter (Coriolis type mass flow meter) and a regulatory control valve with high turndown ratio.

New Central Control Room

The control and information system includes a central control center where the refinery personnel monitor and control the site units through field equipment and instruments. Each unit contains hundreds of monitored and controlled input/output instruments. The information system collects and stores all the site data, and enable refinery employees to use the data on a real time basis as well as through a set of dedicated reports.

Modernisation project stages

  • Study the existing installation (control, wiring)
  • Identify cables and their marking
  • Complete implementation in the new control system and install it alongside with the old one.
  • Switch-over without stopping production - disconnect the cable from the old system and connect to the new, repeating cable after cable. The big advantage: a gradual transition and an immediate identification of wiring errors and malfunctions.
  • Transition during shutdown- transition the rest of the old system to the new system.
