Product Description
Fabricated hauv peb cov khoom siv hnyav hnyav hauv Jingjiang, peb cov Ethylene Cracker yog lub ntiaj teb-chav kawm, siab kub thermal tawg hluav taws xob cua sov engineered los pyrolyze hydrocarbon feedstocks-xws li ethane thiab propane mus rau lub teeb naphtha thiab hnyav atmospheric gas roj-rau hauv polymer-qib ethylene, propylene, co-propene thiab propene. Siv peb cov cuab yeej cuab tam tsim khoom 26 xyoo thiab cov txheej txheem metallurgical siab heev tau lees paub raws li ASME "U" thiab "S" cov qauv, peb tsim txhua tus Ethylene Cracker nrog precision radiant coil geometries thiab high-heat-flux burner zoning kom tswj tau lub sijhawm luv luv nyob thiab siab olefin selectivity thaum suppressing sab hauv coke tsim. Tsim los ua ke ncaj qha nrog kev hloov pauv cov kab hluav taws xob siab (TLE), qhov kev lag luam-qib Ethylene Cracker maximizes tag nrho cov nroj tsuag thermal efficiency thiab khiav-ntev cycles, muab petrochemical producers thiab thoob ntiaj teb EPC cov neeg cog lus nrog ib tug ultra-txhim khu kev qha, high-muaj peev xwm cracking cub tawg ua rau lub feem ntau rau txim rau kev ua hauj lwm regimes.
