Daqing Refining Heat Exchanger Technical Reform Stable Production Reduction

<

The granulation device of the 300,000-ton/year polypropylene plant of PetroChina Daqing Refining & Chemical Company added the E853 to the technical transformation project of the reserve plant. After nearly two months of trials, the flow of the granulation water is currently 640m3/h. Right and left, the heat exchange effect is good, and 200,000 yuan can be saved annually.
300,000-ton/year polypropylene plant When producing high melt index or impact copolymer grade polypropylene products, the extrusion granulator is easy to produce fine powder mixed in the cutting water during the pelleting process, causing the cooler to clog and stop. In order to solve this problem, Daqing Refinery Polypropylene Factory implemented a heat exchanger to increase the technical transformation of Taiwan, in parallel with the original heat exchanger based on the same effect of a heat exchanger heat exchanger. After the heat exchanger is put into use, it can save 90,000 kilowatt-hours per year, which has achieved the intended purpose of technological upgrading.
