On March 28, Dalian Petrochemical Company successfully commissioned China's largest combined atmospheric and vacuum distillation unit with an annual capacity of 10 million tons. The facility produced its first batch of qualified products, marking a major milestone for the company. This achievement brought Dalian Petrochemical’s total refining capacity to 20.5 million tons per year, solidifying its position as the largest refinery base under PetroChina in China.
The new 10-million-ton atmospheric-vacuum distillation unit is a key component of Dalian Petrochemical’s technological upgrade project aimed at processing Russian crude oil. It is currently the largest single distillation unit in China and a flagship project under the country’s "10th Five-Year Plan" for restructuring the oil refining industry. The project incorporates advanced international design concepts, including process integration and optimization, and is equipped with state-of-the-art technologies such as deep vacuum drawing and automatic furnace ignition—techniques that have never been used in China before.
Construction of the unit began on February 22, 2005, and it was completed on November 18, 2005. During this time, all related supporting systems were also finished, ensuring smooth operation from day one. The project officially entered the construction phase on March 15 of this year, further demonstrating the company’s commitment to modernization and efficiency in the energy sector. This development not only enhances Dalian Petrochemical’s production capabilities but also strengthens China’s overall refining capacity and energy security.
.Perilla Seed
1. Lower lipids and blood pressure
The rich linolenic acid in Perilla Seed Oil can reduce serum cholesterol, triglycerides, low-density lipoprotein and very low-density lipoprotein, thereby inhibiting thrombosis and preventing myocardial infarction and cerebral infarction. In addition, α-linolenic acid Acid can also reduce blood viscosity, increase blood oxygen-carrying capacity, inhibit the synthesis of triglycerides, and increase the metabolism of various lipids in the body. Therefore, perilla seed oil has a particularly obvious effect in lowering lipids and blood pressure, especially for hyperlipidemia. and borderline hypertension, the effect is more prominent.
2. Protect liver
The α-linolenic acid in perilla seed oil can effectively inhibit fat synthesis, break down fat and excrete it from the body. Daily consumption can prevent the formation of fatty liver.
3. Strengthen the brain and protect eyesight
CCTV's "Encyclopedia Quest" reported that α-linolenic acid is one of the basic raw materials for nerve cell synthesis and a key nutrient that determines the development of human intelligence. It is called "brain gold". Correct supplementation of linolenic acid can improve the IQ and intelligence of infants and young children. Increase by 20%-30%, pregnant women and children must supplement.
