Bapco units conserve energy, cut emissions.Byline: MANAMA: Bapco's process control and Instrumentation Department has successfully commissioned three advanced process control applications which are helping reduce environmental emissions and conserve energy at its Sitra refinery. The three applications, implemented recently on process heaters in the refinery, have enabled reductions in excess oxygen (O2) emissions of 1.5 per cent, 2 per cent and 2 per cent respectively. These reductions were achieved while maintaining fuel gas pressure, heater outlet temperature, stack temperature, CO and CO2 levels, heater draft and other constraints, and imply significant savings in fuel gas and reduced environmental emissions. The energy-saving applications, part of a wider Bapco programme to minimise fuel gas consumption, were commissioned on heaters installed at three units at the refinery -- No 6 VDU (Video Display Unit) Same as VDT. VDU - Visual Display Unit (vacuum distillation unit), the kerosene kerosene or kerosine, colorless, thin mineral oil whose density is between 0.75 and 0.85 grams per cubic centimeter.

The applications utilise state-of-the-art multi-variable predictive control technology to move the heaters to a safe and economically-optimal operating region. Bapco previously carried out a feasibility study "A Feasibility Study" is an episode of the original The Outer Limits television show. It first aired on 13 April, 1964, during the first season. It was remade in 1997 as part of the revived The Outer Limits series with a minor title change. on ten heaters across the refinery to identify those with the potential to implement an advanced control application.
