Since the successful start-up of No.4 joint station of Northwest Oilfield Branch in April, its negative pressure stripping and desulfurization stabilization technology, which was first implemented in China, has achieved remarkable results. Compared with similar devices in the oilfield, the effect of removing hydrogen sulfide is good and decreases daily The amount of desulfurization natural gas 6 to 80,000, the annual effect of 55 million yuan, optimizing to reduce investment more than 2800 million. In April, the No. 4 Joint Station of Northwest Oilfield successfully put into operation at a time, eliminating the bottleneck of crude oil processing in Tahe Oilfield and ensuring the smooth operation of the oil and gas gathering and processing system. In the tower quadruple joint construction of bold use of new technologies and new processes, especially the bold implementation of vacuum desulfurization gas desulfurization stability process, and achieved significant economic and social benefits. Crude oil stabilization is an effective way to enhance the airtightness of oil and gas gathering and transportation. In the tower quadruple design process, combined with the oil and gas properties of the high-sulfur heavy oil in Tahe 12 area, the comprehensive crude oil stabilization process and stripping desulfurization process were combined to develop full technical solutions and technical and economic feasibility studies. The first innovation in China was put forward and implemented The negative pressure desulfurization stripping gas stripping process, in a device to achieve both crude oil desulfurization and stabilization functions, significantly reducing the loss of crude oil, and achieved significant safety and environmental benefits. Compared with the similar devices in the oilfield, Japan reduced the utilization of natural gas by 60,000 to 80,000 cubic meters; Tower Quad together to reduce a set of natural gas desulfurization equipment and the associated gas pipeline, optimizing and reducing the investment by more than 28 million yuan. After the unit was successfully put into operation in May 2013, it processed approximately 11,000 tons of crude oil per day and reduced the content of hydrogen sulfide in crude oil from 160mg / m3 to 39mg / m3. The removal rate reached more than 80%, which was significantly better than the desulfurization results of similar plants. Effectively reduce the cost of crude oil desulfurization. Nissan mixed hydrocarbons more than 30 tons, converted into an annual output of more than 11,000 tons of mixed hydrocarbons, according to mixed hydrocarbon calculation of 5,000 yuan per ton, the annual increase of direct economic benefits of 55 million yuan. The successful application of the negative pressure desulfurization desulfurization unit in No.4 joint station of Tahe Oilfield has found a new road for the stability and desulfurization of high sulfur content crude oil and can be further popularized and applied in other oil fields both at home and abroad.
