The recent situation of steel development in China can be generalized into three aspects. Firstly, constant global economic recovery will increase Chinese export business, especially under the policy of “Belt and Road”, which encouraged steel company’s export business. Though Chinese infrastructure and estate investment go down,domesticmacro economyruns well, and steel company'sproduction-saleincreases obviously. Secondly, by banning substandard steel and eliminating backward capacity, steel company achieved obvious effects on deducing capacity. Some local policy and environment rules restrict the producing capacity, for which market supply and demand are effectively adjusted. Even the price ofsteelmaterial is variable, it will be keptina high level,meanwhilethe earning ability and standard of steel company will also be keptina high level. Thirdly, technological progress and industrial upgrading insteelindustry will further release quality capacity, but the strict control of

With the development of VPSA-O2 technology , the oxygen-rich cost has been greatly reduced, and the oxygen-rich calcination technology has also been widely applied in cement kilns. The application of PIONEER’s PSA oxygen-rich combustion technology in cement kilns may make cement producers significantly increase the output, save the energy, reduce the pollution and ultimately achieve the win-win purpose of economic benefit and environmental protection. On one hand, the application of the oxygen-rich technology may improve the combustion condition of the coal, greatly reduce the air consumption, shorten the combustion duration, realize the complete combustion, and reduce the waste gas emission and the production of hazardous gas such as CO and NO, so as to elevate the combustion efficiency, save the energy, reduce the energy consumption and protect the environment; on the other hand, it may elevate the temperature and blackness of the flame to largely strengthen the thermal

To avoid or effectively reduce the severely toxic substance "dioxin"  which may be generated during the waste burning, all countries generally adopt the oxygen-rich combustion technology to reduce the secondary environmental pollution caused by waste burning . The application principle of oxygen-rich combustion technology in waste burning: it collects the oxygen in the air to enrich the oxygen content to 25%-30%, and then sends such part of oxygen-rich gas to the burning furnace by the secondary air to increase the overall or partial oxygen content in the furnace and reduce the air excess coefficient of the furnace. Besides, the increase of oxygen-rich gas may improve the ignition condition to realize the complete combustion and smelted slag and reduce the volume to nearly zero, so as to guarantee the complete decomposition and combustion of toxic organic gas such as dioxin. As a result, the application of PIONEER's oxygen-rich combustion technology in the waste

PIONEER may develop the specific technical scheme and implementation scheme of sewage treatment according to the treatment requirement of the users and the sewage ingredients to provide the users with the internationally-leading, scientific, reasonable, effective and low energy-consuming active sludge treatment technique and integrated solution of urban sewage and industrial waste water. Application of VPSA-O2 in the sewage treatment: (1) The aerobic active sludge method replaces the air aeration by the cheap oxygen aeration produced by the PSA method to largely improve the sewage treatment efficiency, reduce the pond area, and lower the construction and operation costs. (2) Water works using the oxygen produced by the PSA method as the raw material of ozone may largely save the energy and lower the construction and operation costs. (3) Oxygen produced by the PSA method achieves outstanding effect in controlling the smelly river. Efficient sewage treatment technology—PI

Total-oxygen combustion smelting technology of the glass industry replaces the air by 90%-93% of oxygen in the gas combustion of heavy oil, coal tar, natural gas and coal convertor in the glass furnace. Total-oxygen combustion is advantageous in reducing the emission of smoke and nitrogen oxide in the smoke and saving the energy. Without considering the energy consumption of oxygen generation, it is generally recognized that the total-oxygen combustion may save over 30% of fuel than the ordinary air combustion. PIONEER’s VPSA-O2 technology can be used to provide oxygen generating devices for the total-oxygen (oxygen-rich) combustion section of glass kilns, with the advantages of oxygen purity of 93% or above, stable oxygen production and flexible load adjustment. Up to now, PIONEER has built more than 20 sets of VPSA-O2 devices for the glass and glass fiber industry, including several oxygen generation projects exported to Bahrain and other countries.

Oxygen bleaching is the widely-applied clean bleaching technology in the paper pulp field. Pulping enterprises equip the bleaching section with oxygen generating devices to generate rich oxygen for the deoxygenation, delignification and whitening sections. At present, most of pulping enterprises with better oxygen bleaching application effect adopt VPSA-O2 technology. The oxygen production of general pulping enterprises is about 200-3,000Nm3/h, with oxygen purity reaching 93%. Under such oxygen consumption, VPSA-O2 technology has more obvious advantages than other oxygen generating technologies. PIONEER’s VPSA-O2 technology boasts the advantages of low investment cost, lower power consumption, simple operation and flexible control. PIONEER has not only rich engineering performance in China, but also has exported its VPSA-O2 technology to the papermaking enterprises in many countries including Russia, Thailand and Indonesia. The devices have been operated stably for many years. PIO

It is an important technical measure to increase the productivity, reduce the energy consumption, control the environmental pollution, improve the technology of metallurgy and increase the economic benefit by replacing the ordinary air with the oxygen-rich air in nonferrous metallurgy. The VPSA-O2 technology of PIONEER may provide the metallurgy of non-ferrous metals such as copper, lead, nickel, zinc, tin and gold with the stable and reliable oxygen source to optimize the energy saving of oxygen-rich combustion technique, largely reduce the oxygen cost and obtain the significant comprehensive benefit. The non-ferrous metallurgy of copper, lead, nickel, zinc, tin and gold, etc. mainly adopts the oxygen-rich air whose concentration is between 24% and 90% and the productivity of the oxygen generating device is generally under 3,000Nm3/h. This is the best parameter range for the PSA device and large-scale oxygen generating device may adopt the combination of several sets. PIONEER
