Daqing Petrochemical Company Chemical Plant No. 1 has strengthened its fine management and its annual production capacity of 600,000 tons of ethylene equipment has achieved its maximum production capacity. As of May 10, the plant produced 219,900 tons of ethylene, and the average daily output exceeded 1,705 tons. The main economic and technical indicators all achieved the best in domestic ethylene plants. The yield of ethylene and propylene “diene†reached 49.97%, compared with last year. Compared with the increase of 0.29 percentage points, the yield ranks first among the national ethylene production enterprises. At the beginning of this year, the plant further strengthened the management of production equipment and critical parts, standardized the standardization of job personnel, strived to improve the quality and frequency of equipment inspection, and adopted a number of process optimization measures to ensure the optimal and stable operation of the ethylene plant. The technicians determine the feed composition and the system temperature based on the operating cycle to effectively increase ethylene production and yield. At the same time, this plant optimizes the operation of cracking furnaces, precisely controls the key factors such as the liquid level of ethylene quench towers, air coolers, etc., and achieves stable cracking of cracking furnaces, reducing the effect of temperature fluctuations during switching on the depth of material processing and ethylene yield, each time. The reduction of ethylene loss by 15 tons can increase ethylene production by about 1,500 tons and increase efficiency by more than 10 million yuan. Through the recovery and secondary utilization of the excess steam in the steam pipe network of the ethylene plant, zero discharge of systems such as steam and condensate can be achieved. Strict water management and control, the implementation of dynamic monitoring of circulating water equipment, saving 62,000 tons in the first 4 months of this year.
The inflatable tent is produced by a combination of adhesive bonding and high-frequency thermal bonding. inflatable camping tent,inflatable tents,inflatable party tent,inflatable house tent,outdoor inflatable tent Ningbo Autrends International Trade Co., Ltd. , https://www.outerlead.com
The air columns are made of PVC double-sided coated fabric and the canopy is made of waterproof and
UV-resistant material, which has the advantages of fast forming, high strength, flame resistance, mold
resistance, UV resistance, and moisture resistance. The tent is an inflatable tent with an air column frame,
which is lighter, smaller, and easier to carry than a metal stand tent.
Set Up
The inflatable tent is relatively easy to set up, just lay the tent flat on an open space, connect it to a
foot pump or an electric pump and it can be set up in a few minutes by just two people.
Dismantling
The same applies to the dismantling of the tent. The dismantling and packing of the metal stand requires
a large number of people and takes a long time. The inflatable tent can be dismantled by simply letting
it deflate naturally or by pumping it up with an electric blower.
The advantages
The inflatable tent has incomparable advantages over ordinary metal tents, being lighter and smaller in
size and having advantages in transport that ordinary metal tents do not have. It is easy to erect and
dismantle and does not waste any more manpower or time, making it particularly suitable for rapid
response to emergencies. The inflatable tent can also be air-dropped when the environment is
too harsh to reach.
