28^th June 2021: The first phase of Sinopec Zhenhai Base project was completed in Zhenhai, Ningbo, Zhejiang. The commissioning of this project will add 1.2 million tons of ethylene annual production capacity and 4 million tons of refining annual capacity to Zhenhai Refining and Chemical. (Source)

27^th Sep 2021: The 4# atmospheric and vacuum unit was put into operation. In 2022, the energy (steam) consumption of the unit dropped from 11.51 kg of standard oil/ton at the initial start-up to 9.45 kg of standard oil/ton, with significant energy-saving and consumption-reducing effects.

18^th Nov 2021: The No. 2 coal-coke hydrogen production unit at the Zhenhai base was successfully put into operation. 
Over the past year (2022), the 2# coal-coke hydrogen production unit has supplied more than 100,000 tons of hydrogen and over 700,000 tons of fuel gas . It has successfully achieved 122 days of operation of the III series gasifier burner, more than 3 months of stable operation of the coal mill, and more than 80 days of wastewater stripping operation, creating the first domestic record of dual-unit operation of propylene compressors.

6^th Jan 2022; The No. 2 propylene oxide styrene (POSM) unit of Zhenhai Base was successfully put into trial operation. 
In the one year since the start of operation, the plant has achieved a stability rate of 99.42% and a product qualification rate of 100% . The plant achieved excellent results in annual PO production of 269,800 tons and SM production of 583,400 tons.  (Source)

2022: The tail oil products produced by the 3# hydrocracking unit are used as the raw materials for the 2# ethylene unit, and desulfurized dry gas is provided as the sulfur injection agent. 
As the largest single-series hydrocracking unit in China, the unit has now (6^th Jan 2023) processed a total of 2.2 million tons of wax oil, 1.64 million tons of diesel, and produced a total of 1.18 million tons of naphtha and 550,000 tons of jet fuel. (Source)

7^th Jan 2023: 
▪️ Today, on the first anniversary of the successful start-up of the ethylene unit, the unit's automatic control rate reached 97% and the stability rate reached 99.5%, the output of ethylene products was 997,500 tons, and the comprehensive energy consumption of the ethylene cracking furnace ranked first in Sinopec.
▪️ As an important downstream unit of ethylene, the 2# ethylene glycol (2# EOEG) unit actively explored the lower limit of the unit's operating load.
▪️ The National Four Units (2# butadiene extraction unit, 3# aromatics extraction unit, 2# MTBE/butene-1 unit, 2# pyrolysis gasoline hydrogenation unit) have made positive contributions to the company's optimization of ethylene production capacity structure, processing C4 to C9 cracking components and integrating them into high value-added economic value products.
