Weihai Puyi Ship Environmental Protection Technology Co., Ltd. waste gas cleaning system was approved by CCS

It is reported that, Weihai Pu Yi Technology Co., Ltd. is engaged in environmental protection ship ship new environmental protection equipment research and development, manufacturing-based high-tech enterprises, committed to the forefront of the industry's ship flue gas desulphurization technology research and application development, is the first Asian manufacturing of ships exhaust gas desulfurization equipment business, have complete independent intellectual property rights, is the world's first production, "magnesium-based method" ship exhaust gas cleaning system of the enterprise. The issuance of the China Classification Society (CCS) accreditation certificate marks that China's ship exhaust gas cleaning system has officially obtained permission to enter the international and domestic markets. The commissioning of this high-tech project has filled China's gap in the field of ship emission control, breaking the western monopoly of similar technologies and reaching the world's leading level, making China's shipping and shipping not subject to foreign manufacturers in environmental upgrading. Green environmental protection will have far-reaching effects.

Weihai Puyi Ship Environmental Protection Technology Co., Ltd. cooperated with Dalian Maritime University to develop the magnesium-based seawater method exhaust gas desulfurization system from the research and development stage. After years of research and testing, we have to COSCON "Ice number" 2014 "Gun Creek No." two container ships onboard test several times, eventually made suitable for maximum fuel sulfur content of 3.5% m / m (mol / mol) Cleaning after reaching the most stringent value of 0.1% m / m provisions "international maritime conventions." The technology has reached the world's leading level. The whole system is miniaturized, automated, modular and intelligent. The application of the ship is smooth, the operation is simple, no additional manpower is taken, and the creation from China to China is realized, and it becomes China's “intelligence”.

According to the survey data of the maritime department, 65% to 70% of the suspended particulate matter (PM2.5) and sulfur oxides come from ships. To this end, the International Maritime Convention incorporates the “Rules for Preventing Air Pollution from Ships”, restricting the amount of SOx emissions from ship exhaust, and gradually increasing the sulfur emission control zone from 2015, while stipulating that by 2020 or 2025, 0.5 The new sulphur oxide emission cap will be effective globally. By 2030, it will eventually increase to 0.1%.

According to the actual situation in China, the sulfur oxides and PM2.5 generated by ships discharged from coastal and port cities account for 30%-60% of the total urban emissions. For example, a coastal container ship emits diesel pollutants equivalent to one day's emissions of 500,000 Chinese trucks.

From the current supply situation of global marine low-sulfur fuel, although Europe can be added to low-sulfur fuel, the price per ton is more than 400 US dollars more than the heavy oil for ships. Most Chinese ships use the “oil change method” to meet the requirements of the Convention when passing through the emission control zone. The first is the use of low-sulfur fuels, but there are problems such as the cost of modification and the increased fuel costs of adding low-sulfur fuels, as well as the loss of using low-sulfur fuels to ship engines. The second is to use liquefied natural gas as an alternative fuel, but it has the problem of natural gas retrofitting and the impact of the ship's endurance. It can be seen that the use of marine exhaust gas desulfurization devices to meet the requirements of the Convention is the best choice.

Compared with similar products on the market, Puyi's ship exhaust gas washing equipment is significantly smaller in volume and weight than similar products, with low energy consumption; and uses MgO or Mg(OH)? and sea water to make it operate at low cost and less solidified material. The washing water runs in the neutral range of PH value and has the characteristics of low corrosivity; the magnesium desulfurization is not easy to scale, no secondary pollution, the ship is stable, the system operation reliability is improved, and the modular design is adopted. Combined with remote monitoring; economic analysis shows that half of the ship's operating mileage is in the emission control zone, the cost of recyclables in the year, and a large net income.

The face of intensive introduction of new regulations of the International Maritime environmental protection, according to DNV GL Group predicts that by 2016 at least 30% to 40% of the world's new ship will install flue gas scrubber. By 2020 or 2025, the new 0.5% sulphur cap will be put into effect globally, and the demand in this market will be further expanded. European shipbuilding companies have successfully realized the industrialization and market sales of exhaust gas scrubbers. Weihai Puyi Ship Environmental Protection Technology Co., Ltd. is the first supplier and professional service provider of ship exhaust gas washing system in Asia. The China Classification Society (CCS) certificate has been awarded, marking the cutting-edge technological breakthrough in the field of environmental protection in China's ships. China's shipbuilding industry provides economic and environmentally friendly desulfurization equipment, without the need to purchase expensive European similar products, and the Ministry of Environmental Protection and the Ministry of Communications contribute to the development of Chinese ship emission standards and the implementation of green ships.
