As a model of transformation of old and new kinetic energy and adjustment of industrial structure in Shandong Province, this project will promote the integration of 65,438+300 million tons of oil refining industry in Shandong Province, which is of great significance for promoting industrial structure adjustment, transformation and upgrading, and improving the level of oil refining integration.
brief introduction
Shandong Yulong Petrochemical issued a bid-winning announcement, announcing that Southwest Chemical Research and Design Institute Co., Ltd. won the bid in the international bidding for six large-scale PSA units, including Yulong Island 20-million-ton refining and chemical integration project (Phase I) 1-4# PSA unit, methanol hydrogen production PSA unit and coal-to-gas combined hydrogen production PSA unit, with a total hydrogen production of 850,000 nm3/h (standard unit/small unit).
Among them, the hydrogen production scale of two sets of reforming gas PSA hydrogen purification devices reached 230,000 Nm3/h respectively, and the hydrogen production scale of high-pressure coal PSA hydrogen purification device reached 200,000 Nm3/h, leading the world in hydrogen production scale.
For Shandong Yulong Refining and Chemical Project, Southwest Chemical adopts new technology, which can extract hydrogen from traditional fossil energy and hydrogen-rich gas to the maximum extent, improve recovery rate, reduce raw gas consumption, reduce energy consumption and carbon dioxide emissions.
The main technologies include: patented technology of double sequential tank staggered flushing; Analysis and design of large PSA adsorption tower: anti-erosion zero leakage program-controlled valve: intelligent control system and expert diagnosis system; High pressure PSA system technology.
