Jinan Refinery FDFCC

There are too few places that engage in FDFCC, and not many people know about it!

The 800,000 tons/year heavy oil catalytic unit of Jinan Refinery, which was transformed using the country's leading FDFCC-Ⅲ (double riser) catalytic production technology, successfully introduced oil on December 17 and achieved a successful start-up. This is the first time that this technology has been promoted industrially. It is preliminary estimated that it can increase economic benefits by more than 100 million yuan per year, setting a model for the transformation and upgrading of similar equipment in my country, as well as the optimization of production and product structure. 　　FDFCC-Ⅲ technology is a new refining and chemical integration technology independently developed by Sinopec Group Corporation with independent intellectual property rights. This technology breaks through the traditional catalytic production process, changing the single riser to a double riser and double fractionation tower process, and by adding equipment such as a gasoline riser reactor, gasoline settler, and auxiliary fractionation tower, the gasoline to-be-generated catalyst is directly introduced into the heavy oil riser pre-riser to achieve high-efficiency catalysis of 'low-temperature contact and large agent-to-oil ratio', thus significantly reducing the sulfur content and olefin content of gasoline and increasing the octane number of gasoline. ； At the same time, the catalytic naphtha is converted into gas products with higher added value such as liquefied gas and olefins. Compared with traditional catalytic production processes, FDFCC-Ⅲ process technology has outstanding advantages such as strong raw material adaptability, flexible product structure adjustment, and low production costs. 　　According to reports, Jinlian's 800,000 tons/year heavy oil catalytic unit was put into operation in the 1980s. Nowadays, problems such as small scale, insufficient processing capacity, low product quality, and unreasonable structure have gradually emerged. After the introduction of FDFCC-Ⅲ technology for renovation, the vitality of the device was restored: The processing capacity has been increased to 1 million tons/year, the production operation has been flexibly selected from a variety of solutions, and the residual oil blending capacity of the unit has been further improved. ； Annual propylene production increased from 125,000 tons to 185,700 tons ； The olefin content of gasoline is reduced to less than 18%, the sulfur content is reduced by about 30%, and the octane number of gasoline can reach 94 ； Eliminate the phenomenon of gasoline 'stuck' and significantly improve the quality of gasoline.

Can the brother upstairs tell us the process flow of FDFCC in detail? We have never done FDFCC. All I have seen are MIP.

Please introduce the diesel quality situation of the FDFCC unit of Jinan Refinery.

Haha, I’m curious about what processes are used in domestic catalysis now? Which one is used the most now?

Ask Changling Petrochemical. The technology used there is relatively mature. There should be relevant information about the technology of Luoyang Institute.

to 3rd floor: There are a few unclear points that I would like to know about: 1. Is the increase in processing capacity due to the adoption of technology or because capacity expansion was considered during design? ； 2. Are there production data on product distribution? I am more concerned about the yield of dry gas, liquefied gas and coke. 3. Is there any data on energy consumption? 4. Is there any analytical data on diesel? Thanks!

Please ask the 3rd floor: 1. How is the quality of your diesel? 2. Did you make any changes to the original regenerator during the transformation? Did you cancel the original dilute phase pipe and use a hammer valve? ； 3. What is the LPG yield? What is the propylene yield?

Daqing Refining and Chemical also seems to have this technology

I went to the Jinan Refinery in October 2008 mainly to look at the FDCC. The products were okay. The sulfur reduction and olefin removal were not much as designed. The main problem was serious agent running, and no unloading was needed. It was probably a problem with the transformation.；

Our company's newly built fdfcc process was put into production on May 16. The main product distribution is as follows: Gasoline 34% Diesel 23% Liquefied gas 11% Propylene 6%. The properties of diesel are very poor, with a density of 950, but the quality of gasoline is good, with an octane number of 94 and no more than 15% olefins.

But I feel that because fdfcc has added some equipment, its energy consumption should be relatively high! And it is said that the running agent is more powerful than other devices!
