For more than two months, the number of cleanup of the tank filter of the condensate stripper of the Qilu petrochemical styrene plant has been significantly reduced, and there is no need to start the steam heating system injected with the original imported scale inhibitor when adding, so that the energy consumption of the device , material consumption has been greatly reduced, the annual energy-saving efficiency of more than 200 million.
The new environmentally friendly styrene-compressor scale inhibitor BL-628YS was independently developed by the Beijing Spirer Science and Technology Research Institute. The preparation technology has obtained national invention patents. Compared with similar imported scale inhibitors, BL-628YS products have stronger anti-scaling effect, lower freezing point, good fluidity, and good compatibility with media, especially when used in winter, so as to avoid crystallization phenomenon, which can be avoided Pipes and equipment injected into the system are clogged. This kind of domestic anti-fouling agent new product can also completely solve the drawbacks of styrene plant's original injection into the imported anti-scaling agent requiring steam mixing, which not only saves energy but also brings great convenience to the operation of the device.
It is understood that the exhaust gas compressor is a key core equipment for styrene plants, consisting of a screw compressor unit and a steam turbine drive. It is also known as the "heart" equipment for styrene plants. Due to the exhaust gas compression and absorption process, the composition of the compressed medium is extremely complex, and contains a large amount of unsaturated active olefins, so that the medium is easily coked and fouled under high-temperature and high-pressure operating conditions, which becomes a constraint on the long-term stability of the styrene device. A major bottleneck in the operation. The most effective way to solve this problem is to add scale inhibitor products in the compressor section. Prior to this, China had no proprietary styrene compressor antifoulant product technology. At present, the compressor antifoulant used in domestic styrene devices is basically monopolized by foreign imports.
According to industry experts, due to the rising prices of related raw materials such as benzene and ethylene in 2009, domestic styrene production companies are facing a great cost pressure, non-integrated styrene enterprises are even facing a situation of reduced production and losses . Effectively reducing the production cost of styrene products and improving the market competitiveness of products are goals pursued by domestic styrene enterprises. The successful application of domestic anti-fouling agents led Qilu Petrochemical's styrene plant to take the lead.
