“If we want to build a petrochemical base with oilfield characteristics and contribute to the service of a hundred years of oilfields, we must 'do fine' existing devices. To make our devices have a healthy body and a good image, we must not stand still. Focus on long-term development.†At the technical seminar convened by Daqing Oilfield Chemical Group last month, Group General Manager Wang Zhiheng said.
Daqing Oilfield Chemical Group produces 35 products including methanol, liquid ammonia and liquefied petroleum gas. Under the background of the profound changes in the external environment in 2009, the convening of such a technical seminar has triggered a major discussion of the device's experience of “doing fine workâ€.
The reporter learned from the experience of the group's “based on existing facilities and refined operationsâ€. A few days ago, the reporter came to the light hydrocarbon fractionation company of the group and witnessed the entire process of the advanced control technology of the pentane fractionation device of the branch. When the workshop director announced that the advanced control system was formally put into use as the general commander, the squad leader issued the operation order according to the operation card, and the operator performed the investment step by step according to the operation card. Throughout the entire process, the “four-in-one†card is always in place, ie, there are instructions, procedures, confirmations, monitoring, and carding.
This device is Asia's largest pentane finessing device. This time advanced control technology is used to further optimize the existing DCS distribution system. This technology was applied for the first time on the same kind of equipment in China, which made a major breakthrough in the comprehensive automation level of the pentane fine fraction device in China and even in Asia. Its biggest role is to overcome various interference factors, achieve stable, rapid and accurate control of the pentane fine separation device, and at the same time optimize the adjustment of process parameters to achieve "card edge" control of product quality and yield. It is expected that the output of high value-added products will increase by more than 7% and the energy consumption will decrease by 4%.
The experience of using the same control technology on the light hydrocarbon fractionation device has shown that the application of the advanced control system reduces the unit consumption of steam under the same load by 7.56%, improves the overall product yield by 0.23%, and the annual direct economic benefit exceeds 2.52 million. yuan.
Methanol Branch's "doing fine" technological transformation is equally exciting. Their industrial waste water medium-pressure steam stripping treatment recovery unit has played a significant role in the past year, so that all industrial waste water treated by the device is used as demineralized water, and it is the first to achieve zero discharge of industrial waste water in the domestic methanol industry.
Not long ago, through technological transformation, they also built a set of ammonia synthesis process condensate and methanol distillation residue middle pressure stripping treatment recycling device, and the water quality meets the reuse water standard. They also dig deep into the potential of the plant and successfully developed a synthetic cryogenic technology that reduces the methanol content of the synthesis tower into the tower gas, makes more efficient use of the catalyst's activity, lowers the steam power consumption of the steam turbine, and reduces the synthesis opening of the reformer inlet. The amount of deflated combustion can create an annual profit of 4.59 million yuan.
The Group’s subsidiary Dongsheng Investment Co., Ltd. is a company that produces surface active agents for oil displacement. The two sets of surfactant production facilities currently owned by the Group are currently at the domestic first-class and internationally advanced level of technology. The company is the only domestic manufacturer of heavy alkylbenzene sulfonate for tertiary oil recovery in oil fields, and also the production base for surfactants for tertiary oil recovery of China National Petroleum Corporation. The output of surface active agents for oil displacement ranks first in the country. The production of surfactants for tertiary oil recovery using heavy alkylbenzenes is the first in the world.
In order to consolidate its leading position in the field of surfactants for tertiary oil recovery, Tosoh Corporation has produced the “Four Fine†brand with precise positioning, precise deployment, precise organization, and fine inspection. In order to increase the first-pass rate of products, they advanced the quality control threshold and strictly controlled the quality of raw materials. From January to October 2009, a total of 425 batches of products were produced, and 26 batches were adjusted. The first time product qualification rate was 93.88%. The annual increase was about 2%.
The Group Technology Development Institute mainly provides technical support for the Group. “We regard improving the quality of existing chemical plant products, enriching product varieties, and strengthening the design and management of advanced wastewater treatment projects as the focus of 'doing fine work',†said Dean Yukeli of the hospital. Among them, they vigorously developed the cyclopentane desulphurization and refining technology to make the sulfur content of desulfurized cyclopentane products meet the requirements of national standards; the new process of cyclopentane refining and extractive distillation developed in cooperation with the University of Petroleum (Beijing) made cyclopentane products The purity increased by 99.2% from 95%. At present, the hospital has completed the development of a 3,000-ton/year cyclopentane desulphurization and refinement process software package. After the project is implemented, the added value of cyclopentane products will be further increased and the application field will be broader.
At this technical seminar, all subsidiaries and subordinate units have formulated the “Doing Fine†plan for 2010. On the basis of reaching consensus, the group announced that in 2010, it will further reduce costs and increase efficiency with “doing fine†and build a petrochemical base with oil field characteristics.
