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.

In practical industrial applications, adsorption separation is generally divided into two categories: variable pressure adsorption and variable temperature adsorption. From the adsorption isotherm of the adsorbent, it can be seen that the adsorbent has a large adsorption capacity for impurities at high pressure and a small adsorption capacity at low pressure. Also from the adsorption isobars of adsorbent, it can be seen that at the same pressure the adsorbent has a large adsorption capacity at low temperature and a small adsorption capacity at high temperature. Adsorption separation using the former property of the adsorbent is known as pressure shift adsorption (PSA) and adsorption separation using the latter property of the adsorbent is known as temperature shift adsorption (TSA).

Pressure Swing Adsorption (PSA for short) is a new gas adsorption separation technology, which has the following main advantages: (1) high product purity; (2) generally work at room temperature and low pressure, bed regeneration without heating, energy saving and economy; (3) equipment is simple, easy to operate and maintain; (4) continuous cyclic operation, which can be fully automated. Therefore, when this new technology was introduced, it has been the attention of national industries, competing development and research, rapid development and increasing maturity.

With the increasing industrialisation, the pollution of VOCs has a tendency to expand further. And with the recent environmental protection policies become more and more stringent, the emission control of organic pollution waste gas becomes more important. Here we take a look at what technologies are available at home and abroad? What are the advantages and disadvantages of each?

The absorption capacity of ionic liquid for sulfur dioxide is very strong, the amount of solvent recycling is only 1/15~1/5 of MDEA solvent, and the consumption of public works is much lower than that of MDEA solvent absorption and regeneration.
