The petrochemical industry manufactures chemical products from natural gas and suitable types of mineral oil.
VOC emissions occur at virtually every stage of the petrochemical manufacturing process, from the drilling, transportation and (un)loading of tanks to the purification of oil, gas and coke-based raw materials in refineries.
During this gas scrubbing process, tail and sour gas emissions can be treated using Dürr LTB Ecopure® TAR thermal oxidiser technology. In the downstream steam cracker the first reaction takes place. Using raw materials such as ethane, LPG, naphta and hydrowaxes, intermediate products such as ethylene, propylene and BTEX-compounds are produced.
These intermediates can then be used to create the downstream chemicals ranging from rubber to LDPE, PP, EPS, etc. Here, VOC emissions can be treated using Dürr LTB Ecopure® RTO technology and NOx emissions using Dürr LTB Ecopure® SCR systems.
Last, but not least, off-gases from the waste water treatment plant (WWTP) in the chemical process can be treated using Dürr LTB Ecopure® RTO technology in combination with Dürr LTB Ecopure® FGA or Ecopure® PAS scrubbing systems.
