calcined petroleum coke
The aosta No. 1 delayed coking unit produced 1150 tons of 3C calcined petroleum coke. This is the third batch of 3C calcined petroleum coke produced in the past two months. The cumulative output has reached 3,800 tons, which has achieved remarkable results.
Petroleum coke is a by-product of oil refining. After the crude oil passes through the atmospheric and vacuum unit to form vacuum residue, it then undergoes cracking and coking reaction in the delayed coking unit to produce black solid coke. At present, the calcined coke on the market is divided into three quality grades: A, B, and C according to the sulfur content, and the prices vary greatly. C-level high-quality calcined petroleum coke has strict requirements on crude oil sulfur content and other parameters.
In the past two months, Aosta seized the opportunity to process a new low-sulfur crude oil in the No. 1 atmospheric and vacuum unit, and carried out 3Ccalcined petroleum coke production research, through optimizing the crude oil processing plan, exploring the best production ratio, etc., to overcome inexperience and so on. Difficulty, successfully used this kind of crude oil to produce 3Ccalcined petroleum coke. Sampling analysis results show that the sulfur content is in full compliance with relevant standards.
Aosta seizes the bullish opportunity of calcined petroleum coke, accurately studies market demand and price trends, and flexibly adjusts sales strategies by increasing the production of marketable products to achieve an increase in production and sales of calcined petroleum coke. As of November 4, Daqing Petrochemical has sold 144,200 tons of calcined petroleum coke, achieving sales revenue of 256 million yuan, and accumulative efficiency gains of 18.6 million yuan.
It is understood that aosta implements the “one policy per day” work requirements for improving quality and efficiency, scheduling each set of production units according to the best efficiency processing route, giving priority to meeting the demand for residual oil from delayed coking units, and reasonably increasing the cycle ratio of delayed coking units; The coking unit mainly processes residual oil, reduces the slag mixing ratio of 2 sets of catalytic units, and increases the mixing ratio of catalytic oil slurry from 7.5% to 11.6%. Deeply tap the potential of the operation status and production structure of the unit, and increase production at full capacity. Calcined petroleum coke has a daily processing capacity of more than 3,100 tons.
The company’s sales, storage and transportation center focuses on market research and research, actively communicates with customers, improves service levels, and adopts appropriate and flexible sales strategies to achieve mutual benefit and win-win results. In order to maximize the benefits of calcined petroleum coke, according to crude oil prices and the price trend of calcined petroleum coke of similar enterprises, timely adjust product ex-factory prices and flexibly control price adjustment nodes. In October, calcined petroleum coke pushed prices 5 times, totaling 800 yuan/ton.
With the delay of the large-load production of the coking unit, the volume of calcined petroleum coke products has increased significantly, which has brought severe challenges to the loading work. To this end, Daqing Petrochemical Refinery strengthened communication with the storage and transportation center and relevant departments, actively coordinated vehicles, formulated a loading plan, and ensured the smooth delivery of calcined petroleum coke. At the same time, special personnel are assigned to do the vehicle deployment and safe driving at the car loading site to ensure the efficiency of the calcined petroleum coke products. In October alone, the company sold 15,600 tons of calcined petroleum coke and realized sales revenue of 36.4 million yuan.
