Description

There are mainly two kinds of biogas purification, one is biogas upgrading by pressure swing adsorption method, and the other is purification by biogas membrane separation.

Biogas upgrading by pressure swing adsorption method

Production description:

Type:	Tower Reactor
Material:	Stainless Steel
Capacity:	>1000L
Structure:	Filling Tube
Pressure:	Positive
Agitator Model:	Turbine Agitator

Pressure swing adsorption (PSA) is a technology used to separate carbon dioxide from biogas under pressure according to molecular characteristics and affinity for an adsorbent material. It operates at near-ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation. Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap, preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed material.

Absorbent:
Aside from their ability to discriminate between different gases, adsorbents for PSA systems are usually very porous materials chosen because of their large specific surface areas. Typical adsorbents are activated carbon, silica gel, alumina, resin and zeolite. Though the gas adsorbed on these surfaces may consist of a layer only one or at most a few molecules thick, surface areas of several hundred square meters per gram enable the adsorption of a significant portion of the adsorbent's weight in gas. In addition to their selectivity for different gases, zeolites and some types of activated carbon called carbon molecular sieves may utilize their molecular sieve characteristics to exclude some gas molecules from their structure based on the size of the molecules, thereby restricting the ability of the larger molecules to be adsorbed.

Advantages and application:
The advantages of pressure swing adsorption gas purification process, such as high product gas purity, automatic operation, flexible starting and stopping, etc., have made it develop rapidly in recent years, and its technology has become increasingly mature. It has become a very important gas production technology. Widely used in chemical, petrochemical, metallurgy, electronics, light industry, medicine and other fields. The purification of mixed gas by pressure swing adsorption mainly uses porous solid substance as adsorbent, and uses the equilibrium adsorption amount of impurity gas and product gas to purify and separate the gas.

Purification by biogas membrane separation

Product description:

Type:	Air Separation Plant
Object:	Biogas
Separation Mode:	Filter Type
Operating Type:	Continuous Type
Installation:	Horizontal
Pressure:	Medium Pressure

Biogas membrane purification equipment is a kind of biogas engineering equipment which removes carbon dioxide from biogas (or landfill gas) by advanced hollow fiber gas separation membrane technology. It is suitable for the purification of biogas and landfill gas. Biogas purification can be used as the substitution of natural gas products, methane concentration can reach above 95% by compression / provide standard 25MPa vehicle gas (CNG) filling device can be integrated synchronous compression products, the pressure or the pressure to the standard of the natural gas pipeline after the nearest access local gas pipe network.

The significance of desulfurization:
Hydrogen sulfide is an inorganic compound. Under normal circumstances, it is a colorless, flammable acid gas. When the concentration is low, it has a foul smell and smells like rotten eggs. When the concentration is high, there is no smell, because high concentration of hydrogen sulfide can paralyze the olfactory nerve. It can be dissolved in water. At 0ºC, 1 mole of water can dissolve about 2.6 moles of hydrogen sulfide. The aqueous solution of hydrogen sulfide is called hydrogen sulfuric acid, which is a weak acid. When it is heated, hydrogen sulfide escapes from the water. Hydrogen sulfide is a kind of acute toxicity, which can be fatal in a short time by inhaling a small amount of high concentration hydrogen sulfide. Low concentration of hydrogen sulfide has effects on eyes, respiratory system and central nervous system.
Hydrogen sulfide is a strong neurotoxin, which has a strong stimulating effect on mucous membrane. Tears, eye pain, intraocular foreign body sensation, photophobia, blurred vision, runny nose, burning sensation in throat, cough, chest tightness, headache, dizziness, fatigue, confusion, etc. appear after short-term inhalation of high-intensity hydrogen sulfide. In severe cases, brain edema and pulmonary edema may occur. When the concentration is extremely high (more than 1000Mg/m3), the patient may suddenly fall into a coma within a few seconds, resulting in lightning death. High concentration contact with conjunctiva causes edema and corneal ulcer. Long-term low concentration exposure can cause neurasthenia syndrome and autonomic dysfunction.
Environmental protection and new energy is the theme of development in the 21^st century. The treatment of air pollution is imminent, among which desulfurization is very important.Biogas, natural gas, coke oven gas, semi-water gas, oil associated gas, gas and wastewater contain toxic gas of hydrogen sulfide, which seriously corrodes equipment and pipelines. Inhalation of a small amount can cripple Days and Nights in Wuhan and seriously endanger life. Sulfur-containing gases must be removed from hydrogen sulfide before they can be used as clean energy.
With the rapid development of economy, desulfurization treatment is the key to solve the problem of environmental pollution. It is a responsibility of our environmental protection industry to improve the desulfurization efficiency in an all-round way. To promote the continuous improvement of environmental quality, create the greatest value for the society and build a beautiful world with sky blue, green space and clear water!
