New QYD pressurized feed gas desulfurization tower composite high efficiency mass transfer internals

  At present, the vast majority of desulfurization towers for wet desulfurization basically use packed towers
With the continuous expansion of the production scale of the enterprise, the tower diameter is becoming larger and larger, and the disadvantages such as difficult gas-liquid distribution and tower blockage in the tower are becoming more and more prominent
Under this situation, the gas purification design and research center of our company has researched and developed QYD special gas-liquid distribution mass transfer device for medium and high pressure feed gas desulfurization tower through a large number of investigations and many laboratory simulation experiments and with the support of colleges and universities such as Changchun University of technology
The device has the advantages of high efficiency, energy saving and environmental protection, integrates the advantages of many traditional tower internals, and further strengthens the gas-liquid mass transfer process
It makes full use of the desulfurization reaction mechanism & mdash& mdash; Based on the principle of rapid chemical reaction between H2S and alkali solution, gas-liquid direct contact is adopted, and special gas-liquid contact device and bubble redistribution device are set according to the H2S content to make dynamic contact between gas-liquid and turbulent mass transfer
This not only greatly increases the gas-liquid contact area, makes the gas fully mix and contact with the liquid in a very short time, and greatly improves the gas purification degree, but also uses this mass transfer device to replace the filler, which completely solves the outstanding problems in the desulfurization industry for many years & mdash& mdash; The desulfurization tower is blocked
QYD has been comprehensively upgraded in the past two years, and the technology has applied for a national patent again, with the patent number of 201610855852

It is the most valuable mass transfer internals in pressurized feed gas desulfurization tower at present
Its successful application will be a revolution in desulfurization tower internals

Advantages and technical characteristics of new QYD desulfurization tower composite mass transfer internals ◆ do not block the tower
The special structure has solved the problem of blockage of packed desulfurization tower for many years
◆ improve the sulfur capacity of desulfurization solution, reduce the circulation amount of solution, stabilize and improve the gas purification degree
Whether used for new tower design or old tower transformation, after the unit is put into operation, the sulfur capacity of desulfurization solution will be doubled, so that the circulation amount of solution will be reduced by about 30 ~ 50% compared with that of packed tower
◆ it integrates the four main parts of the packed tower, reduces one-time investment, and makes the internal structure of the desulfurization tower more scientific, concise and clear
If it is used in the new tower design, the height of the tower will be about 1 / 3 lower than that of the packed tower with the same diameter
Compared with packed tower, it can save 50% of one-time investment cost
◆ when the device is used in the design of a new tower, because the height of the tower is greatly reduced, the pump head is about 10m lower than the original, which greatly reduces the power consumption of the desulfurization system
Because the gas-liquid contact time is greatly reduced, the effect of CO2 in desulfurized feed gas will be effectively improved, which is more conducive to the selective absorption of hydrogen sulfide, the regeneration of solution, the flotation of sulfur foam and the reduction of NaHCO3 formation rate
◆ if it is used for the transformation of the old tower, the production capacity of the tower will be increased by more than 10% after the unit is put into operation
3 application performance , Since the technology was used in Shandong Ningyang Feida Chemical Technology Co
, Ltd
in November 2007, its ideal application effect has been widely concerned by the industry
The novelty and practicability of its technology have been brought into full play
The technical characteristics of its energy-saving, environmental protection and anti blocking tower have won the favor of many enterprises and quickly popularized in the industry
At present, the internals have been successively used in Shandong Zibo Qilu Yihua, Shanxi Tianzhushan chemical, Henan Kaifeng Jinkai investment holding company, Yanjin Yanhua, Hebei Jinshi jinwantai chemical, Hunan Zhuzhou Zhicheng Chemical, Hubei Dangyang Huaqiang chemical, Xiangyang Zedong chemical, Xiantao Hengxiang chemical, Jiangsu Xuzhou Fengcheng salt chemical, Zhejiang Lanxi Fengdeng chemical, Ningbo Siming chemical The production and application of dozens of chemical fertilizer enterprises, such as Liuzhou Chemical Industry in Guangxi, Hechi chemical industry, Tongliao gold coal chemical industry in Inner Mongolia, have achieved good results
We sincerely hope that our technology can bring rich economic benefits to the majority of chemical enterprises
