CSB Technology Thermal Oxidiser Package by Dumag GMBH Austria

In the video, a case study on a mega project executed by Dumag GmBH is demonstrated. We present the case study of 2.9 MW thermal input direct fired thermal oxidizer-based package designed and built by DUMAG and installed at ITC Rubis terminal in Beveren (Belgium). This project can be termed as replacement of existing flare systems in Tank farms / refineries with state-of-the-art Thermal Oxidizer based package using propriety CSB technology by Dumag. The main aim of this project was to offer our client a solution to drastically reduce the operating expenses as well as CO2 emissions done by the conventional flare systems. 

DUMAG installed the proprietary DUMAG CSB burner in the unit at ITC Rubis; this burner is capable of achieving a turn-down ratio as low as 1:30 without compromising in safety. Automatic control of the burner neck position maintains a constant pressure drop resp. gas velocity over the burner. When the amount of waste gas is lower, the burner will adjust and the cross-sectional area of the burner becomes smaller. This keeps the velocity constant at the burner neck, offers an effective measure against flame flashback and replaces the traditionally used dynamic flame arrester based on flow addition.

A significant reduction of the volume of air added (and therefore also additional auxiliary fuel) was possible as a result of this development, and the idle operation state (vent gas flow equal to zero with unit lined up) can now be realized with as little as 10 Nm³/h natural gas, which is needed for compensation of heat losses through the insulation and via the stack.

The replacement system by Dumag offers a verifiable improvement has been achieved. Assuming 2000 hours of idle time operation per year, a saving of approx. 1000 MWh of natural gas can be realized. This equals more than 200 tons of CO2 emission reduction per year.
