Technologies to enhance Ethylene production

(Webinar) - In this presentation, three technologies will be introduced. This first is swirling element radiant tube (SERTTM) technology for steam cracking furnaces. In this technology, you will find how heat transfer theory is applied to overcoming the challenges of cracking pyrolysis to meet targets. Successful commercial cases will demonstrate the technical advantages of SERTTM technology. Cracking furnaces with SERTTM technology have longer operating days, lower tube wall temperature (TMT), and wide applications. A detailed economic evaluation is also provided to illustrate the economic advantages of SERTTM technology.

The second technology is catalysts and technologies related to the ethylene separation process. In this section, you will learn about C1 low temperature methanation catalyst, C2 selective hydronation catalyst, and C3 selective hydrogenation catalyst (also called C1/C2/C3 catalysts). The physical properties and technical advantages for each demonstrated catalyst will be shown. In addition, you will be given two commercial cases that show the industrial application and performance of C1/C2/C3 catalysts.

The third focus is cold oil absorption technology (COATTM), a process to recover C2 fraction in dry gas. The principle of COATTM is explained to show its technical advantages. Compared with cryogenic separation and pressure swing adsorption (PSA), COATTM can not only achieve a high recovery rate (more than 93% C2 is recovered) and high product quality of C2 (O2 < 1 ppm and NOx < 10 ppb), but also requires less equipment and has a longer operating cycle. In addition, the operating temperature of COATTM is above 0 ℃. Successful commercial applications will be shown to demonstrate that COATTM is able to handle different types of refinery dry gas.
