Recently, Chengdu Yizhi Technology Co., Ltd. participated in the drafting of the "cement kiln oxygen-enriched combustion technical specifications" group standard, by the China Association of Industrial Energy Conservation and Cleaner Production was officially released, since July 7, 2023 onwards.

Our company has been devoted to the development and application of Variable Pressure Adsorption Air Separation Oxygen Generation Technology (VPSA-O2) since 1994, and achieved industrialisation in May 1995 with the completion of Variable Pressure Adsorption Air Separation Oxygen Generation Plant. The oxygen production equipment built by our company has superior performance, low production cost and no environmental pollution.

Variable pressure adsorption device has the advantages of fast start-up - low energy consumption, simple operation, wide range of load operation adjustment and simple maintenance.

The adsorption performance of the adsorbent on each gas component is evaluated by experimentally determining the isothermal adsorption curve under static condition and the outflow curve under dynamic condition. Good adsorption performance of adsorbent is the basic condition of adsorption separation process.

Aiming at the actual situation of epidemic and pressure of prevention and control during the construction period, all departments took care of epidemic prevention and control with one hand and project construction with the other hand, and actively responded to the challenge of epidemic, took multiple measures and eliminated all the difficulties, and finally completed the construction target with quality and quantity.

In order to thoroughly implement the important instructions of General Secretary Xi Jinping on the cause of people with disabilities, and in response to the call from the higher levels, on 21 May, on the occasion of the 33rd National Day of Help for People with Disabilities, the "Love Around Us - 2023 National Day of Help for People with Disabilities Public Service Activity" was successfully held at the Haosheng Hall of the Zunyue Luxury Hotel in Jinniu District, Chengdu, China. 2023 National Disabled Persons' Day Public Welfare Activity" was successfully held in the Hawthorne Hall of Chengdu Jinniu District Zunyue Hawthorne Hotel! The theme of this year's "National Day for the Disabled" is "Improve the social security system and care service system for the disabled, and promote the comprehensive development of the cause of the disabled".

The caring enterprise Sichuan Huaxi Chemical donated masks to the cooperative unit in Wuhan, an infected area, and made a concerted effort to fight the epidemic.

Huaxi Chemical Technology July 11 news, by Chengdu Huaxi Chemical Technology Co., Ltd. construction of Zhejiang Petrochemical 40 million tons / year refining and chemical integration project phase II project 1 #32000 standard cubic meters / hour gasification hydrogen thickening device design phase progress smoothly.

Chengdu Huaxi Chemical Technology Co., Ltd. has always adhered to the development tenet of "technology as the forerunner, quality as the focus, service as the core", and the development strategy of "standardisation, specialisation and internationalisation" for 20 years, and has been making progress step by step, year by year, winning applause, obtaining flowers and making brilliant achievements. We have won the applause, obtained the flowers and made the brilliant achievements.

The development of hydrogen energy in foreign countries is no longer purely in the field of technology, but due to the important role of hydrogen energy system technology in the national economy, the concept of a new economic model of "hydrogen energy economy" has arisen. Recently, some experts have proposed a new stage of development towards a "hydrogen civilisation" in the future. However, the progress of commercialisation of hydrogen energy is still slow, and in the case of developed countries, even though the technical conditions for hydrogen energy are mature, it is still in the demonstration stage.
