2. Industrialization Development of High-fluidity Shock-resistant Polypropylene and Research in Its Processing and Application
Aiming at satisfying the domestic demand of High-fluidity Shock-resistant polypropylene special material, the Company developed M2600R. With new catalyst and conditions of technical operation improved, the product entirely meets the requirements of High-fluidity Shock-resistant polypropylene special material in terms of such indexes as melt flow rate and resistance to shock and pressure. It can be widely used, for example, in large-scale thin wall injection molding, and all its performance indexes can rival imported special material of the same kind.
3. Development of Industrial Technology of Two-step High-speed Spinning of 1.67dtex High-shrinkage Acrylic
Under the premise of not changing the constituents of the polymer, NaSCN two-step Acrylic manufacturing technique is adopted to enhance the fiber’s tractility and its potential shrinkage capability by intensifying steaming heat setting. Then it is drafted 1.6 to 1.7 times to obtain the shrinkage ratio of 32%-36%. The process of development doesn’t need further investment, which is both economical and efficient.
4. Technical Package of PTA Plant with Annual Output of 0.8 Million Tons
The Company developed the 0.8-million-ton/year PTA packaged technology after it managed to reconstruct the 0.3-million-ton/year PTA plant into the 0.4-million-ton/year one and then formed the PTA packaged technology with independent intellectual property rights. The technical package adopts the processing flow of two PX oxidation reactors, TA uniserial crystal separation and hydrofining. The technology is advanced and reliable with a low consumption of materials and resources. The quality of products is up to the standard. The discharge of “three wastes” meets the requirements of environmental protection and its technical indexes reach the world advanced level.

5. Pilot Research in Making 1, 3-Propanediol from Acrolein
The technique flow of making 1 -Propanediol from acrolein is reasonable. The design of main equipment including hydration reactor, rectification tower and 3-HPA intermittent hydrogenation reaction chamber meets the technical requirements. In the project, innovative catalyst and techniques are adopted in the process of Hydration of Acrolein and de-aldehyde refining; 12 invention patents have been applied for, among which, 7 have been authorized. Compared with similar techniques at home and abroad, this one is of world advanced level. The breakthrough in the production technology of 1,3-Propanediol products offers a good chance for developing new terylene PTT.
6. Industrial Experiment on Recovering and Purifying Hydrogen from Hydrogenated Tail Gas of Diesel through Membrane Separation
The tail gas of the 2# refined oil 1.2Mt/a diesel hydrofining plant contains more than 80% hydrogen. In other words, there is about 2,200t hydrogen released along with polymer tail gas into the net of fuel outlet pipes and burnt as fuel every year. The achievement of the experiment purifies and recovers hydrogen from the hydrogenated tail gas by using hollow fiber membrane separator, reducing the loss of hydrogen when tail gas is released into the net of fuel outlet pipe. The result of the reclamation experiment indicates that the purity of the recovered hydrogen meets the requirements on purity and pressure of the net of hydrogen pipe of the Refining and Petrochemical Division.
7. Application of LGH Intensified Burner to Hydrogenation-Cracking Plant BA-105 Heating Furnace
In order to increase the comprehensive heat effect of BA-105 heating furnace of hydrogenation-cracking plant of aromatics plant, we adopt intensified heat transfer technology by using tubular burner, design and develop the hydrogenation-cracking plant with characteristics, and produce the supporting LGH intensified heat transfer burner and burner nozzle. Intensified heat transfer technology ends the history that heating furnace was alteration bottleneck of capacity expanding and energy saving of oil refining plant, and changes the design idea of heating furnace. It not only reduces the alternation investment and production cost dramatically, but also has a prodigious promotion and application value.
8. Development and Industrial Application of FF-16 Hydrogenation-Cracking Pretreatment Catalyst
The industrial application of new-type hydrogenation-cracking pretreatment catalyst (FF-16) further removes the “bottleneck” of capacity expanding alternation and improves processing ability and product quality. Its function status and plant calibration result show that when material oil quality is in a continuous poor condition, denitrogenation activity of FF-16 catalyst is higher than the 3996 and foreign reference catalysts of the same kind applied in the former round, and hydrogenation activity is obviously higher than the like catalyst widely applied in industry at home and abroad. It is in an international leading position in this field among the lately updated like catalyst and provides technology condition for our similar products to become one of the leaders in the world.
9. Industrial Application Experiment of New-Type Electron Donor and Development of New Products
The small-scale pilot research, magnification of medium-scale pilot testing and industrial application experiment of 0.2 million tons/year localized cannular technical plant II of the second generation demonstrate that D-DONOR is practicable on loop polypropylene plant and boasts a stable operation. The set of application technology of the new type electron donor owned by SPC, an innovation in loop polypropylene technology, takes the leading position at home. There is a prospect for obvious economy benefit after the update of the polypropylene catalyst system.
10. Research in and Development of Antibacterial and Moisture-Conductive Acrylic Fiber and its Textile
The program employs acrylic wet spinning technique with NaSCN as solvent and adopts the treating technique of natural antibacterial finishing agent receiving after treatment in oil trough. According to the testing data of testing centers including Shanghai Institute of Microbiology, the product has good antibacterial performance and hygroscopicity with almost equal qualities comparing with the foreign products of the same kind. Textile made of this fiber features such qualities as anti-bacteria, anti-mold, antistatic and anti-wrinkle.
11. Development of Full Dull Polyester Production Technology
With the help of the polyester production technique of direct-esterification and continuous-condensation-polymerization and through the technical improvement of titanium white modulation system equipment, we developed titanium white modulation technique for continuous industrial production and polymerization & polycondensation technique of full dull polyester chips. These techniques enable the direct production of full dull fiber, without adding master batch, by making necessary adjustment on the content of TiO2 within a certain range.
12. Development of Generator Power Automatic Tracking and Regulation Equipment in Second Thermal Power Station of General Thermal Power Plant
The automatic tracking and regulation equipment used in this program is composed of SSC-2 distributed computer remote terminal unit (RTU), frontal-end system and SJ-200 back-end monitor system. It is the ideal real power automatic tracking and regulation equipment of power plant, with advanced technique, stable and reliable operation and high price/performance ratio. Since the application of automatic regulation system, electricity that is confiscated has decreased obviously and the Second Thermal Power Station has gained good economic benefit. At the same time, the equipment lessens the operators’ work intensity and improves efficiency.
13. Research in Production Application of Manganese Removing in Low-Silicon Water System
By efficiently removing manganese in water, content of organisms and algae is greatly reduced, so is the degree of pipe encrustation and corruption. It also has significant meaning for cutting down Sinopec Corp.’s overall operation cost. Industrial application of potassium permanganate pretreatment in low-silicon water manganese removing technique, a novel and practical one, has not been reported in domestic documents.
14. Tentative Industrial Study on Isomerization Reaction of Isopentene
This project perfects the patent technology of isomerization reaction by improving the former reactor system in many respects. The modified reactor pattern and control scheme of temperature, airspeed and moisture of reconstructed reactor increase the system processing capacity by over 20%, considerably prolongs the life-span of catalyst and improves product quality steadily. The annual production will increase by about 1,000 tons because of the rise of capacity.
15. Industrial Experiment in Improving Selectivity of Dicyclopentadiene (DCPD)
We work out a feasible industrial experimental scheme and a process flow in this project. By using mathematical model, a pipe reactor R201, for cyclopentadiene dimeration is designed to improve reliability. Through technical innovation, the problem of low de-cyclopentadiene capacity is solved, as well as the bottlenecks of yield and purity decrease in products of chemical grade isoprene and meta pentadiene. The new technology will be adopted in the prospective 0.15-million-ton/year C5 separation plant because of its successful application in C5 separation plant.
16. Technical Studies on Making Cyclopentanol and Cyclopentanone from Cyclopentene
The project adopts the technology of making cyclopentanone by dehydrogenation from cyclopentanol generated from cyclopentene by hydration, and develops a series of C5 products, taking DCPD as the leading one, which extends the product chain and increases the added value of DCPD products. In the study on making cyclopentanol by hydration, transformation rate of cyclopentene and selectivity and yield of cyclopentanol are increased by adding organic solvent. This achievement plays an important role in improving comprehensive utilization of C5 and economic benefit of the enterprise.
