Remarks: (1) we can make other natural gas purificatio, , , n equipments with larger capabilities according to the users’ need.
(2) If the temporary purification capacity use for long term, the content of the sulfur will increase about 30% and water will increase about 20%. (3) The purification equipment can also purify methane, gas, liquefied petroleum gas and so on. The effect is the same as natural gas purifying.

2. Equipment structure and feature
1) the equipment is made up of the furnace body, purification tank, oil-water separator, the explosion-proof installation, pipe network and temperature control devices and so on.
2) Equipment Features
l Lower investment: the effect of removing the organic sulfur and inorganic sulfur in the Methanol or the Ammonia is the same in the beginning comparing the two-step removing sulfur method, but the effect of the two-step method will be worse and worse after half year (absorbed sulfur can not spit, but produce water, so it is easy to block).. In the two-step method, it is very harmful that the mixture of Fe2O3ZnO2 will bring in lots of moisture with method of solid-state or wet-alkali for carburizing atmosphere in the heat treatment. The activated carbons which remove the organic sulfur in the Methanol or the Ammonia will be inactivated by 50 times regeneration in old method. The investment of our equipment is lower more than a half. The floor area can be narrowed more than 2 / 3, and the running cost is much lower after putting into production.

1100mg/m3时, When the external pressure is very low, it will not appear obstruction phenomena; when the outside Gas Field gas desulfurization equipment overhaul its inorganic sulfur as high as 1100mg/m3, there is no downtime, just shorten the regeneration cycle.
l Long lifespan of Purifying agent (service capacity).Chongqing Construction Group has been used for 22 years. Chongqing Machine Tool factory has been used for 19 years, the service capacity is still OK now.
l The bestl quality of products (can be comparable to any developed country in the world)

The non-martensite in the surface of the Carburizing pieces is the least(after shallow etched, it can be controlled below 0.003mm in the long-term. It is not easy and stable for imported equipment of the low-pressure vacuum carburizing quenching to reach this target due to various reasons); Smooth surface without carbon black, carbon black generally needn’t to burn. The work pieces’ surfaces are smooth and silver-no carbon black in the generating directly carbonitriding at 850~860.3μmThe carbon content in the surface is the highest, and the carbides are extremely diffuse. The surface hardness is more than HRC 61 (HV1 conversion), and the thickness of the non-martensite is less than 3μm.
l Reduce the production costs at a large extent

Comparing the kerosene, propane, acetone and other carburizing gas sources, the carburizing time can be shortened about 15%, and the cost reduces (Chongqing Heavy Vehicle manufacturing company can save at least 350,000 yuan per year by using the purified natural gas instead of propane to carburize; Changchun FAW-Volkswagen, at least saves up to 50 million every year; Zhuzhou gear company saves about 850,000 yuan per year). In the same conditions, the consumption can be reduced 20 % and the rate of carburizing can be enhanced about 11% by use purified natural gas .
l Further extend the service life of heat treatment equipment. (Chongqing Machine Tool factory uses Aichelin 2 with minor repairs in 19 years. purifying agents have been used for 19 years and run well.)
l l Purifying agent can be used for more than 10 years without changing. l The equipment is novel, unique, safe, reliable operation and easy to operate.
3. Complete scope of supply. furnace body, electric control cabinet (including instrumentation), thermocouple wire and compensating wire, operating instruction manual
4. Range of uses: purified natural gas can be used in multi-purpose furnace, push plate stove, Zhen-hearth furnace, mesh belt furnace, pit furnace for shielding gas atmosphere, nitrogen carrier gas and rich gas in the controlled atmosphere heat treatment such as direct health type, heat type or heat-absorbing-type. Its can be also used for the steels with bright annealing, normalizing, quenching, carburizing, carbonitriding treatment and gas soft-nitriding, and used for fuel in heat furnace and CNG car.
