On December 8, after the construction of Ningbo Engineering Co., Ltd. for one and a half years, Zhenhai Ethylene's 160,000-ton/year butadiene extraction plant successfully achieved CCCC. This device is a set of engineering projects submitted by Ningbo Engineering Co., Ltd. following the transfer of ethylene cryogenic tanks, aromatics extraction equipment and pyrolysis gasoline hydrogenation equipment. At present, the company is in the process of transferring ethylene to Zhenhai as planned on December 28. Make this goal.
The 160,000-ton/year butadiene extraction plant is divided into a process unit and ancillary facilities, among which the process unit includes an extractive distillation unit, a butadiene refining unit, and a solvent recovery unit; auxiliary facilities include solvent buffering, chemical addition, and TBC recovery. , Exhaust gas separation, safety relief system, device analyzer and analysis cabin, steam and condensate system, DCS system, emergency stop system and public distribution system, in addition to power distribution stations and field control stations.
In order to ensure smooth delivery of the butadiene extraction plant, Ningbo Engineering Co., Ltd. has been actively organizing construction since the start of construction and has gone all out to fight for the construction period. It has endeavored to participate in the labor competition of Zhenhai Ethylene's “100 days of major work†and “70 days of decisive battleâ€. Activities, hardships and difficulties, completed one after another engineering node. The butadiene equipment has completed the installation of 1504 tons of steel structure, 85,000-inch diameter process pipeline, 11 towers, 27 vessels, 2 spherical tanks, 33 cold-exchange equipments, 61 pump pumps and related electrical and instrumentation work. the amount.
