What parameters are considered for new catalytic cracking units?
Thread Content
We plan to build a new catalytic cracking unit with a capacity of 4 million tons. The management wants to go and conduct an inspection; this has been done before, but what should I pay attention to? What to ask?
It’s best to first consult a reputable design firm to prepare a feasibility study, covering aspects such as raw materials, products, the selection of process packages, and the choice of design firm; you can message me privately
If you go down the chemical route, it is recommended to take the DCC route directly
We actually visited several companies to see the facilities on site, and to understand the sources of raw materials, the sales of finished products, as well as the supporting infrastructure. The issue with such facilities lies in the raw materials used.
Based on the source of raw materials, it is necessary to examine similar companies to understand which company’s manufacturing technology is being used The process route is determined based on market conditions, with efficiency being the top priority.
Personally, I think going with hydrocracking is better; it won’t be phased out
How was the preliminary investigation? Has the basic route been determined? If you want to know something specific, feel free to ask me. I have worked on such projects, covering the entire process from preliminary investigations to the start of construction. 4 million is a fairly large amount; it’s among the highest in China. The process routes, technical approaches, equipment models, and technical frameworks – many of these aspects are closely related to the overall planning of your entire company. It’s not something that can be explained in just a few words. You can send me a private message, and I’ll do my best to respond to you. Catalysis is exhausting; good luck! !
With such a large catalytic system, a refinery capacity of 10 million tons is required; it is recommended to add hydroprocessing for residue oil at the beginning
Thank you, boss. We have 440,000 tons of unpolymerized diesel feedstock every year. Everyone says that this material contains a high amount of aromatics, making it difficult to polymerize. I was wondering if you also have this kind of feedstock available? What is the actual effect?
It’s difficult to process this; hydrogenation will improve things significantly. I’m not sure if you have the capability for diesel hydrogenation or wax oil hydrogenation – either would work
