Refining & Petrochemical

Yokogawa provided a Dynamic Real-Time Optimizer (RT-OP) to optimize the operations of the hydrocracker unit at Aramco Riyadh Refinery.
By dynamically calculating optimal setpoints, the RT-OP optimizes operations beyond the APC system.

Measurement and control of Heat Exchanger Leakage can help prevent costly maintenance, repair and downtime. The simple, essentially maintenance-free measurement of condensate conductivity will give the operator information necessary (or provide automatic control) to prevent severe damage to the boiler should a breakthrough of the heat exchanger occur.

Ion Exchange is a method for the exchange of ions between two electrolytes or between an electrolyte solution and a complex molecule. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic ion exchangers.

The U.S. refineries represent approximately 23 percent of the world's petroleum production, and the United States has the largest refining capacity in the world. Petroleum refining is an industry, which is undergoing intense amounts of scrutiny in the United States from regulatory agencies and environmental groups.

The client wanted to monitor the temperature on a chimney. Exhaust air is exposed to the heat on the way traveling from the inlet to the outlet in the chimney. Then constituent of the air transform to harmless elements. It is important to keep the temperature in the chimney as designed.

Gasoline and Diesel blending applications of on-line Near Infra-red (NIR) analysis and control are well documented in the literature, and the economic benefits of NIR control systems have been reviewed recently.
