As a  Hydrogen Peroxide Industrial Plant , let's talk about the factors that affect evaporation. Evaporator structure The structure and state of the evaporator determine the efficiency of evaporation. The heating coefficient α on the side of the heated steam condensation is relatively large, while the heat transfer coefficient α on the methanol side is relatively small. In the structural design, the heat supply coefficient on the methanol side should be strengthened to achieve better heat transfer efficiency. Therefore, at the time of design, the circulation speed of the raw material methanol is high, so as to improve heat transfer and enhance evaporation. 2. Evaporation temperature It is common knowledge that liquids are vaporized by heat and evaporation. It is affirmative to increase the temperature to facilitate the evaporation of methanol. However, when the liquid temperature is lower than the boiling temperature in the operation, the liquid vaporization can only be ca

Whenever you mention formaldehyde in your life, everyone is a look of panic. It is thought that the newly renovated rooms and offices are filled with the smell of formaldehyde. If you stay in a formaldehyde-containing environment for a long time, you will be at risk of death. As a  Formaldehyde Production Plant , we are going to talk about the use of formaldehyde as a basic chemical raw material today, hoping to change your understanding. Formaldehyde is a popular chemical product that is widely used, has a simple production process, and has sufficient raw material supply. It is the backbone of methanol downstream products. The world's annual output is about 25 million tons, and about 30% of methanol is used to produce formaldehyde. However, formaldehyde is a low-concentration aqueous solution. It is not convenient for long-distance transportation from an economic point of view. Therefore, it is generally located near the main consumer market, and import and export trade is also

Today,  Hydrogen Peroxide Manufacturing Plant , to explain to you the harm of carbonation reaction during the heating process of silver formaldehyde production. And how does it relate to the reaction temperature? What is the hazard of the carbonation reaction? During the heating process of silver formaldehyde production, the free carbon particles generated by the carbonation reaction will adhere to the surface of the catalyst particles, so that the active surface area of the catalyst is reduced, and the performance of the catalyst is not effectively exerted, which shows an increase in side reactions and CO2 in the exhaust gas. The CO content is high, and the methanol content in the product is high, resulting in an increase in methanol unit consumption. Its relationship with reaction temperature The temperature range of the carbonation reaction is between 530 and 580 °C. Although the activity of the electrolytic silver catalyst increases rapidly between 530 and 580 °C, it

Power outages are divided into all power outages and partial power outages, and measures should be taken for specific causes and locations of power outages.  Hydrogen Peroxide Plant Supplier  believes that the following treatments are generally available: All power outages: Fans and pumps should be completely stopped. Pay attention to "tempering". For the air and methanol mixed evaporation process, it is necessary to prevent the methanol from being pressed down to the blower. 1. The oxidizer with the bypass valve should be opened immediately, and the positive valve should be closed to protect the catalyst; 2. Immediately close the air and exhaust blower outlet valve to prevent methanol from being pressed down; 3. The evaporator is heated by steam to close the heating valve; 4. Close the batch steam valve; 5. Stop the absorption tower from adding water and stop the formaldehyde production; 6. Close the methanol into the evaporator valve and the methanol gas in

The silver formaldehyde production process affects the reaction temperature by two factors: 1. oxygen to alcohol ratio; 2. water to alcohol ratio. So, how to change the reaction temperature of silver-formaldehyde production? As a  Hydrogen Peroxide Manufacturing Plant , let's explain it to everyone. 1. Increase the oxygen to alcohol ratio by lowering the evaporation temperature or increasing the evaporator inlet air pressure/air flow. The degree of oxidation reaction of exothermic heat in the catalytic reaction increases, and the degree of endothermic dehydrogenation reaction decreases, and the temperature of the catalyst bed rises; 2. Increasing the water-to-alcohol ratio by increasing the amount of steam to be added, and removing the heat of reaction faster to achieve a reduction in the temperature of the catalyst bed.
