Chemicals Production and Operation
In 2017, we produced 11.61 million tonnes of ethylene and 4.625
million tonnes of PX, up by 550 thousand tonnes and 290 thousand tonnes,
respectively. The proportion of new and specialty products in synthetic
resin reached 63%, up by 1.6 percentage points; that of high-value products
in synthetic fiber rose to 29.4%, up by 3.7 percentage points; that of highvalue
products in synthetic rubber was 24.7%, up by 4.2 percentage points.
Production and operation realized stable growth.Close coordination
between production and marketing was made with dynamic optimization.
We paid close attention to the stable operation of flagship equipments,
conducted ethylene crackers contest, eliminated potential hazards and
pushed forward debottlenecking. For the whole year, reliability rate of
ethylene facilities reached 97.49%, up by 1.33 percentage points, and
unscheduled shutdown was lowered by 2 times and 23 days.
Structural adjustment continued to evolve.In feedstock structural
adjustment, targeting at maximizing input-output efficiency, we adopted
dynamic optimization and ethylene yield rate for the year was 66%, marking
a new high. In product slate adjustment, supported by technological
innovation, we deepened the integration between production, marketing,
research and application and optimized manufacturing among enterprises and workshops based on product types and grades. The replaced import
volume of three major synthetic materials reached 210 thousand tonnes. In
facilities structure adjustment, we focused on benefits of the entire product
chain, shifted from “shutdown to reduce loss” to “increase production and
profit” by reasonably scheduling the operation and shutdown of facilities.
Good progress was made in coal chemical projects.Utilization rate of
major facilities in Sinopec Great Wall Energy and Chemical Co. (Ningxia
Province) increased significantly. The company accumulatively produced
1.40 million tonnes of chemicals and generated 2.95 billion kilowatt-hours
of electricity, up by 45% and 23%, respectively. Its sales revenue was 3.26
billion yuan, up by 82.4%. Zhongtianhechuang Project was put on steam and
went into commercial operation. For 2017, it produced 4.51 million tonnes
of chemicals and 14.98 million tonnes of raw coal, and realized 3.59 billion
yuan of sales revenue. Zhongan United Coal Chemical Project fully recovered
construction with all of its major units for chemicals being constructed.
Accumulative progress reached 58.01% of its overall schedule. Preparatory
work for Guizhou Zhijin Coal-to-Olefin Project and Xinjiang Coal-to-Gas
Project continued to advance.
