Methanol, Ammonia purification equipments  These series of products, which have been obtained the national patent of invention (patent number: zl200710078354.8), can remove the harmful substances such as the organic sulfur, inorganic sulfur, moisture in the Methanol or the Ammonia at the same time by one step.1. Specifications of the products CNJ-□: C-means Methanol; N-means Ammonia; J-means purification equipment; □ - means the models and codes of gas production 2. The main technical parameters (Note: we can make other Methanol or Ammonia purification equipments with larger capabilities according to the users’ need.) Remarks: If the temporary purification capacity use for long term, the content of the sulfur and water will increase about 30%. The Methanol is calculated by gasification conversion.
 3. Abstract of the structure  This 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. 4. Advantages of the equipment 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. 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. Good purifying effect Comparison of the effect before and after purification in the Methanol& Ammonia. types unit inorganic sulfur organic sulfur water (dew point) Before purification mg/m3 ≤ 100 ≤ 100 ≤ 24 ℃ After purification mg/m3 ≤ 1 ~ 3 ≤ 3 ~ 5 ≤ -40 ℃ Long lifespan of Purifying agent (service capacity): It can use more than 10 years if the gases can reach the marked index. Good product quality (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 with good equipments); Smooth surface without carbon black, carbon black generally needn’t to burn. The black organizations (metallography by non-corrosive) significantly reduced, generally reduced by 1 / 2, and only little black net left in the soft nitriding, Reduce the production costs in a large extent: the time of carburizing, carbonitriding, soft nitriding can be reduced about 15%. Further extend the service life of heat treatment equipment. Purifying agent can be used for more than 10 years without changing. The equipment is novel, unique, safe, reliable operation and easy to operate. 5. Range of uses: purified methanol, ammonia can be used in multi-purpose furnace, push plate stove, Zhen-hearth furnace, mesh belt furnace, pit furnace for shielding gas atmosphere 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. 6. Complete scope of supply: furnace body, electric control cabinet (including instrumentation), thermocouple wire and compensating wire, operating instruction manual. |
