| Introduction | Hunan Litai is an atmospheric management high-tech enterprise invested and constructed by Yueyang Xingchang to carry out energy-saving and environmental protection technology services, integrating R&D, design, manufacturing and technical services. As a comprehensive service provider for VOC control, can provide EPC, BOO Air pollution prevention and control projects carried out through various engineering models can provide key materials such as catalysts and adsorbents required for VOC control. It is a member of the grid of large petrochemical central enterprises such as Sinopec. |
Products
| Conventional catalyst The conventional catalyst developed by Litai uses cordierite honeycomb ceramics with high mechanical strength and strong thermal shock resistance as the carrier, transition metals or precious metals as the active components, and uses a special process to make the active components in the catalyst highly uniform. Dispersed and has strong interaction with the carrier. It can meet the needs of conventional VOCs exhaust gas purification such as benzene, alkanes, alkenes, alcohols, aldehydes, ketones, phenols, ethers, acids, and esters. |
 |
| Anti-poisoning catalyst The anti-poisoning catalyst developed by Litai is optimized by improving the acidity, alkalinity and oxygen vacancies of the carrier surface, respectively, for sulfur-containing and different active components are introduced into the chlorine waste gas, and special coating materials are used to enhance the sulfur resistance and chlorine resistance of the catalyst. |
 |
| High Nitrogen Selective Catalyst Litai targets nitrogen-containing organic compounds, such as DMF, dimethylamine, acetonitrile and other nitrogen-containing organic compounds. Based on their characteristics,Developed a special catalyst, which has multiple invention patents and has strong catalytic activity and N2 selectivity.High, it can selectively convert nitrogen-containing organic matter into nitrogen, carbon dioxide and water, and realize waste gas conversion.The emission of VOCs and nitrogen oxides meets the emission standards, and no secondary treatment is required. |
 |
| Low carbon alkane catalyst Litai uses special oxygen storage coating material, with precious metals platinum and palladium as active components, using a specialThe preparation process exposes the active sites to a great extent, increases the specific surface area, and has catalytic It has the characteristics of low temperature and good stability, and can catalytically degrade ethane and propylene at lower temperatures. Alkanes can meet the needs of low-carbon alkanes purification in the petrochemical industry. |
 |
| carbon monoxide catalyst Based on Litai's anti-toxic catalyst, a special catalyst developed specifically for carbon monoxide exhaust gas can stably convert carbon monoxide under high humidity, with both anti-toxic and anti-carbon deposition properties. It is suitable for exhaust gases containing carbon monoxide from industries such as steel and coking. |
 |
| Olefin adsorbent LTX-I Olefins such as propylene and ethylene have low boiling points, small molecular diameters, high volatility, and difficulty in adsorption. They are basic raw materials for petrochemical industry. This product mainly uses a unique process to promote the formation of the pores required during the activation process, making the activated carbon more microporous, with a pore diameter of about 0.2~0.3nm, and an olefin molecular diameter between 0.3~0.5, thereby improving the product's resistance to propylene and ethylene. The gas selectivity and adsorption performance are enhanced, and the activated carbon is washed with acid and alkali to make the pH value neutral, reducing surface functional groups and effectively preventing olefin polymerization. The propylene adsorption capacity for engineering applications reaches about 14%, which is 3 to 4 times higher than ordinary activated carbon. |
 |
| Desulfurization adsorbent LTX-S LTX-S modified desulfurization activated carbon contains modified carbon groups, which improves its mechanical strength and ability to absorb reactive organic sulfur. In the presence of oxygen, it will oxidize substances such as hydrogen sulfide mercaptan thioether with a foul smell into High boiling point substances are present in the carrier of the deodorization catalyst. The product performance is higher than that of traditional zinc oxide desulfurizers. Its large specific surface, suitable pore structure and surface structure are suitable for petroleum mining, refining, coal chemicals, coke, and steel. Wait until VOC comprehensive desulfurization control in multiple industries. |
 |
| chemical filter media LTX-C380 Chemical filter materials are formulated with special chemical formulas and can effectively remove odors, toxic and harmful gases and corrosive gas pollutants. The chemical filter material removes gaseous pollutants through chemical adsorption and reacts chemically with the gaseous pollutants. The gaseous pollutants are converted into harmless solids and remain inside the filter material. Different from simple physical adsorption, in chemical adsorption, odors and toxic gases are converted into harmless salts and remain inside the filter material. Once the pollutants are removed from the environment, they can no longer return to the air, effectively eliminating air pollution. Secondary pollution of the environment. |
 |
| Catalytic oxidation technology Safety catalytic oxidation technology adds a number of safety designs to traditional catalytic oxidation technology. The control system can automatically perform functions such as exhaust gas concentration adjustment, reaction temperature control, and system safe shutdown. The hardware measures are equipped with high-standard mechanical flame arresters. , bursting discs, safety instruments and automatic valves, etc. It can perfectly realize the safe and automatic treatment of catalytic oxidation of medium and low concentration exhaust gas. At the same time, in terms of design scale, Litai Environment has realized the practical application of 100-120000m³/h full air volume span devices. |
 |
| Cyclic nitrogen sealing technology In the treatment of exhaust gas from nitrogen-sealed storage tanks, nitrogen is usually directly emitted as purified gas. The value of the nitrogen emitted every year can reach hundreds of thousands to millions of yuan. In order to realize the full recovery of oil and nitrogen resources, Lita Environment As a pioneer in the industry, we have developed cyclic nitrogen sealing technology suitable for the treatment of nitrogen sealing exhaust gas from oil storage tanks. Compared with the traditional oil and gas recovery process that only recovers organic matter, this technology dually recovers oil and gas resources, and the device recovery cost cycle is short. At the same time, Achieving “0” tail gas emissions |
 |
| Oil and gas recovery technology In the process of oil storage and transportation, due to frequent oil loading and unloading and limitations of process technology and equipment, some components will inevitably vaporize into the atmosphere, causing resource losses and environmental pollution. Oil and gas recovery technology couples multiple processes to achieve hydrocarbon recovery and tail gas purification in oil and gas. |
