Saw a message. It is said that Wuyang Steel has recently developed chromium-molybdenum steel plates with a thickness of 193 mm for Zhenhai Refining & Chemical to be used in manufacturing heat exchangers, which are important equipment for new project construction. [Major Chemical Equipment] 225–193 mm thick, with a weight of 46 tons; vanadium-added Cr-Mo steel plates: https://bbs.hcbbs.com/thread-3343596-1-1.html (Source: Hua Hai Chuan Liu – Haichuan Chemical Forum Website)
It should mainly be a more pronounced shift of the products toward the chemical industry. Ethylene production has doubled, while refinery capacity has hardly expanded; it is likely that only the amount of crude oil processed has increased, with the extra naphtha being used to produce more ethylene.
Do you think it’s possible for crude oil to undergo direct cracking? ? ?
This post was last edited by qugd on 2022-5-24 at 14:07. It is entirely possible; Sinopec began researching direct cracking of crude oil a few years ago. It seems that a petrochemical project a few days ago already adopted an olefin production process based on the direct cracking of crude oil. The direct cracking process for crude oil also has high requirements regarding the type of crude oil; naphthenic crude oils are not suitable for this process, as they tend to coking quickly and yield low levels of olefins.
The expansion project at Ningbo Zhenhai Refining & Chemical Co., Ltd., which is part of Sinopec Group Company Limited, to increase oil refining capacity by 15 million tons per year and ethylene production by 1.2 million tons per year, is progressing smoothly. The ignition and heating process of the ethylene cracker was successful on the first attempt, and the commissioning of various units is underway in an orderly manner. There is full confidence in achieving the goal of starting up these units for trial operations by the end of the year!
Huizhou is in the preparation stage; it seems that the plans have changed. Tianjin is set to build a furnace with a capacity of 200,000 tons. It is said that Shunbei will carry out direct cracking of crude oil, but nothing has been done yet
Zhenhai is going to launch phase two, with installations using some new materials
Direct cracking of crude oil requires strict control over its properties; it is more likely that paraffin-based or paraffin-intermediate base crude oils should be used
A few years ago... work began on research, just research alone; large-scale production seems to still require time.
