Five-day breeding of bioethanol from duckweed can breed a generation

Zhang Dongyuan told the reporter about the growth of duckweed.

The introduction of duckweed is easily reminiscent of the green of the Manjiang River after the eutrophication of water, but few people know that this aquatic plant contains more than 30% of starch and can be used to convert it into bioethanol and solve food problems. Converting the problem of "competition with people for food" brought about by bioethanol. On August 19th, the reporter went to the basement of the Institute of Bioenergy and Bioprocess Research of the Chinese Academy of Sciences in Qingdao and saw nearly a hundred kinds of duckweed collected from all over the country. Experts recently discovered that the sunshine is divided into 10 “fed” layers for different layers. Duckweed, the production speed can be greatly improved.

Bioethanol is a new energy source

On August 19th, a courier company in Daocheng City contacted Zhang Dongyuan, an associate researcher of the Energy Plant Resources Team at the Qingdao Institute of Bioenergy and Process Research. He told him that there was a parcel sent from Changsha, Hunan to Qingdao. To the surprise of the reporter, the parcel was just a spa. The water bottle is still floating in green duckweed. "What we are looking for is this kind of duckweed. It can produce bioethanol."

Zhang Dongyuan said that duckweed is rich in starch, and the technology for converting starch into bioethanol is very mature. All they have to do is to screen out hundreds of duckweed species with high starch content and genetically modify them. Starch is extracted from it. “The process of producing bioethanol with duckweed is similar to that of brewing wine. In fact, it is a process of fermenting and producing alcohol with bacteria.” Zhang Dongyuan said that bioethanol is a new energy that the country is currently advocating. It can replace fossil fuels to solve energy crisis, cars, etc. The industry needs it.

Up to five days breeding

“The use of duckweed has many advantages, and the growth rate is just a bit faster. It can breed for 2 to 5 days in the wild and 1 to 2 days in the laboratory. This speed can satisfy the raw material for industrial production. Demand.” Zhang Dongyuan introduced that the other advantage of using duckweed to produce bioethanol is environmental protection. Duckweed was originally a product of eutrophication of water. By cultivating duckweed, nitrogen and phosphorus content in eutrophic water can be greatly reduced. “A wastewater treatment plant in Qingdao used duckweed rich in nitrogen and phosphorus to cultivate duckweed. It found that the growth effect was very good, and the level of heavy metals in the sewage was also greatly reduced.

Layered lighting increases productivity

On the 19th, the reporter followed Zhang Dongyuan to the lab where he saw a square box of different sizes with specific collection sites. Recently, this research team has also entered into a number of equipment that provides light to duckweed. “My study found that when duckweed receives one-tenth of light, the growth rate is close to the level when receiving full light. If the light is increased, the growth rate will not increase significantly.” Zhang Dongyuan explained that they decided to use points. The method of layer culture divides the sunlight into ten separate irradiations, which originally produced 1 unit of duckweed so that 10 units can be produced. (Text/graphic reporter Li Xiaozhe)

The Line Pipe System is used for conveying gas, water, and oil in both and natural gas industries etc.

Casing pipe is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.

The tubing is used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes.
