This also makes sense intuitively to me. Spectrum taken from Nimbus ii over the equator. In fact spectra from space show that the main CO2 bands are saturated in the lower atmosphere with minimal emission from the high atmosphere. Thus doubling of CO2 increases the area of surface heating and mixing globally and thus the increase the global average surface temperature, as we have measured over the past years, and especially the last two decades.

Garlic in the diet, such as in juice provides protection against certain cancers while garlic supplements do not. Take a look at: Spinach is a good source of vitamin A, vitamin K, and potassium.
Juicing spinach can add iron to the diet. Iron is essential for the oxygenation of the blood and cell growth. Manganese is a mineral in spinach that supports bone health and maintains healthy blood sugar levels. Adding spinach to juice recipes provides calcium and folate. Calcium helps prevent bone degeneration. Folate is especially important for pregnant women since it reduces the risk of birth defects. Tomatoes contain many vitamins and minerals that our bodies need. Vitamins A, B, C, and K as well as zinc, iron, and potassium are found in tomatoes.
Lycopene is a powerful antioxidant in tomatoes. Research has shown that consuming tomatoes reduces the risk of certain cancers such as colon, stomach, mouth, cervical, and pancreatic cancer. Lemons are rich in vitamin C and antioxidants. Vitamin C supports the immune system. Beta carotene in lemons supports eye health and helps protect bones from osteoporosis. Juicing lemons with the rind can provide a phytochemical known as limonene. This phytochemical can reduce the risk of cancer.
However, lemon rind contains oxalates which can pose a problem for people with gout or kidney disease. Pineapples contain vitamin C, potassium, and B vitamins. Bromelain is an enzyme contained in pineapple that can aid digestion and also has anti-inflammatory properties.
Adding ginger to juice recipes can reduce nausea and stomach distress. Ginger may also help reduce the risk of colon cancer. Be sure to read my article: Cinnamon helps the body fight off the common cold and mild bacterial infections. Adding cinnamon to juice recipes may help control blood sugar and reduce joint pain.
Cinnamon may also help reduce the risk of heart disease. Cinnamon is another concentrated source of antioxidants like Ginger. Blueberries are rich in antioxidants and vitamin C. Juicing with blueberries can help the body overcome urinary tract infections since they contain compounds which fight bacteria in the urinary tract. Recent studies also suggest that blueberries may help to slow cognitive decline by protecting brain cells.
This means that blueberries may help to keep your brain and memory working properly as you age. Mint has been used as a medicinal herb for thousands of years. It also has antiseptic and antiviral properties making it useful for treating colds and flu. Adding mint to your juices is a great way to excite your taste-buds too!!!
Wet scrubbers can achieve high removal efficiencies for either particles or gases and, in some instances, can achieve a high removal efficiency for both pollutants in the same system.
However, in many cases, the best operating conditions for particles collection are the poorest for gas removal. In general, obtaining high simultaneous gas and particulate removal efficiencies requires that one of them be easily collected i.
For particulate control, wet scrubbers also referred to as wet collectors are evaluated against fabric filters and electrostatic precipitators ESPs.
Some advantages of wet scrubbers over these devices are as follows:. Some disadvantages of wet scrubbers include corrosion, the need for entrainment separation or mist removal to obtain high efficiencies and the need for treatment or reuse of spent liquid. Wet scrubbers have been used in a variety of industries such as acid plants , fertilizer plants, steel mills , asphalt plants, and large power plants. Various factors in addition to time and use can cause a chemical or particulate scrubber to degrade and operate less efficiently.
Unfortunately, if your equipment is not working properly, your operations could be negatively affected, and because of this, it is extremely important to conduct scrubber repairs, retrofits and upgrades as soon as they are needed. Here are the most common issues for wet scrubbers:. Since wet scrubbers vary greatly in complexity and method of operation, devising categories into which all of them neatly fit is extremely difficult. Scrubbers for particle collection are usually categorized by the gas-side pressure drop of the system.
Gas-side pressure drop refers to the pressure difference, or pressure drop , that occurs as the exhaust gas is pushed or pulled through the scrubber, disregarding the pressure that would be used for pumping or spraying the liquid into the scrubber. However, most scrubbers operate over a wide range of pressure drops , depending on their specific application, thereby making this type of categorization difficult.
Another way to classify wet scrubbers is by their use - to primarily collect either particulates or gaseous pollutants. Again, this distinction is not always clear since scrubbers can often be used to remove both types of pollutants.
Wet scrubbers can also be categorized by the manner in which the gas and liquid phases are brought into contact. Scrubbers are designed to use power, or energy, from the gas stream or the liquid stream, or some other method to bring the pollutant gas stream into contact with the liquid. These categories are given in Table 2. Corrosion can be a prime problem associated with chemical industry scrubbing systems. Fibre-reinforced plastic and dual keys are often used as most dependable materials of construction.
