| Summary: | 碩士 === 國立高雄科技大學 === 環境與安全衛生工程系 === 107 === Human industrial activities use fossil fuels, such as coal and oil, to produce a large amount of carbon dioxide emissions into the atmosphere, causing atmospheric greenhouse effects; in the atmosphere a thousand years before the industrial revolution, the atmosphere The carbon dioxide content is maintained at about 280 ppm (i.e., 280 unit volumes of carbon dioxide in one million units of gas). After the industrial revolution, after the 1950s, the rate of increase was faster. By 1995, the concentration had reached 358 ppm[1].
The petrochemical industry plays a pivotal role in Taiwan's economic contribution, but it also causes a lot of pollution to the air. Therefore, the government's requirements for environmental protection are also increasing year by year, to improve the existing equipment to reduce energy consumption in response to the trend of world environmental protection. The energy recycling and reuse equipment will be added, and the new process will be developed towards the goal of energy recycling and high energy consumption and low energy consumption.
The hydrodesulfurization workshop in the petrochemical plant is a factory set up in response to environmental protection requirements. The purpose is to reduce the sulfur content of the oil and reduce the sulfur oxides of the air. A heavy oil hydrodesulfurization workshop introduced “no segment capacity” in 2016. The control system improves the capacity adjustment of the hydrogen reciprocating compressor in the hydrodesulfurization workshop, replaces the previous sectional capacity control with the stepless control method, improves the work efficiency of the reciprocating compressor, and achieves the purpose of energy-saving and carbon reduction
This study evaluates the difference between pre-improvement and post-improvement through theoretical estimation and actual operation data collection and evaluates whether the investment equipment meets the legal carbon emission exchange method and benefits.
The HOERBIGER company’s HydroCOM stepless capacity control system estimates the 75% load based on the relationship between the 0%~100% load of the reciprocating compressor and the indicated power, and the energy-saving evaluation performed in the case of 8,000 hours of operation per year. There is a big difference between the actual and recorded current and target current, which is very unreasonable.
