Cracking furnaces are the most important pieces of equipment within ethylene plants because they define the product yield of the entire plant. Selas supplies the highest capacity ethylene furnaces available in this industry.
In cracking furnaces, raw materials asuch as ethane, liquefied petroleum gas (LPG), naphtha, atmospheric gas oil (AGO) and hydrocracker residue are converted into ethylene and valuable by-products.
Linde’s proprietary PyroCrack® technology optimally meets customer requirements for the full spectrum of feedstocks. Linde’s exclusive short-residence time coil designs achieve maximum olefin yields and excellent furnace run lengths. In cracking furnaces, cracked gases are produced after quenching and delivered to the separation train where the cracked gas can be separated into individual products.
Selas twin radiant cell design, two radiant cell cracking furnaces with a common intermediate convection section, has been designed with ethylene production capacities of up to 250 metric tons per year. These capacities allow Linde to supply today’s mega-crackers while minimizing the number of furnaces needed for these plants. As a result, our furnace capacities set the benchmark regarding capital and operational expenditure for cracking furnaces.
Selas furnaces have consistently fulfilled their guarantees regarding thermal efficiencies and emissions. Linde provides ethylene furnaces that comply with all environmental requirements and are therefore low on emissions. The furnaces are equipped with state-of-the-art low NOx or ultra-low NOx burners, or Linde can design them with a selective catalytic reduction (SCR) system incorporated in the convection section.
