Technical field
This utility model relates to one and goes into operation heater, is specifically related to a kind of going into operation for SNG device
Heater, and use the heating system that goes into operation of this heater that goes into operation.
Background technology
Natural gas is a kind of efficient, cleaning fuel of high-quality, and China's demand growth in recent years is rapid, from
2000 to 2009 annual datas show, Natural Gas In China consumption figure average growth rate per annum nearly 16%, 2009
Reached 887 billion cubic meters, the same period yield average growth rate per annum about 13%.But Natural Gas In China provides
Source shortage, constrains natural gas and produces and application, and economic development is also produced by annual " gas is waste "
Give birth to negative effect.
Coal synthetic natural gas (SNG) is based on the feature of china natural resources natural endowment, by the height of coal
Effect converts, production clean energy products, and is transported to the target market of each gas by pipeline,
Possessing the bigger market advantage, natural gas from coal technology is the most ripe, and energy conversion efficiency is high, single
Position calorific value water consumption is low, is one of most important developing direction of New Coal Chemical.Utilize coal resources phase
To abundant advantage, optimum development natural gas from coal, formed natural gas supply is useful and necessary
Supplement, be beneficial to coal in China and clean utilization and ensure the energy safety of supply.
The core technology of natural gas from coal process route is methanation technology, the earliest by LURGI of Germany
Propose when half industrial experiment factory investigates with the engineer of South Africa Sha Suo company.External research and development
Being for the purpose of producing substitute natural gas, current large-scale methanation technology develops ripe abroad.
Can provide complete set technology mainly has the LURGI of Germany, the rope company of Top of Denmark, Britain
The Ju Dian energy company etc. of Davy company and the U.S..
LURGI and South Africa Sha Suo company have built a set of half industrialization by the F-T coal-to-oil factory of South Africa
Coal synthetic natural gas assay device, meanwhile, LURGI and Austria's Ai Erpasuo natural gas companies
Another set of half industrialized Natural Gas Test device has been built at Austria Vienna petrochemical plant.Two
Set assay device has all carried out the operating of long term.The Topsoe company of Denmark uses oneself exploitation
Special-purpose catalyst, has built 12m3The pilot-plant of/h, the substitute natural gas of energy output high-quality, first
Alkane volume fraction, up to 94%～96%, can meet Natural gas standard and the requirement of pipeline conveying completely.
The CRG technique of Davy company of Britain, can make methanation pressure be up to 3.0～6.0MPa, can subtract
Few equipment size, uses this catalyst can produce the substitute natural gas of high-quality, methane volumetric mark
Up to 94%～96%.The natural gas from coal technology of Ju Dian energy company of U.S. exploitation is also known as " blue gas skill
Art " under the conditions of gentle " catalysis ", direct catalytic reaction also produces the natural gas that cleaning is flammable,
Have that coal is widely applicable, technique is simple, equipment manufacturing cost is low, the advantage such as energy-conservation and environmental protection, produce
Natural gas meets pipeline transportation condition standard.
The coal synthetic natural gas project that China was granted in recent years is more, such as: Inner Mongol Datang is international
Keshiketeng Banner natural gas from coal project, Fuxin, the Datang world, Liaoning natural gas from coal project, Shenhua collect
Group natural gas from coal project, Huayin Electric Power Group Ordos, inner Mongolia Ejin Horo Banner natural gas from coal project,
Xin Kuang group Xinjiang Yili of China 10,000,000,000 m3/ a natural gas from coal project, Xinjiang, Huaneng Group company natural gas from coal
Project.Along with the sharp increase to Natural Gas Demand, domestic natural gas from coal project occurs in that flourish
The impetus, becomes the coal chemical technology bright spot of investment after coal liquifaction.Due to domestic coal synthesis of natural
Gas technology is the most not mature enough, and current synthetic natural gas technology major part all uses Davy company of Britain methane
Metallization processes (HICOM technique), or Topsoe company of Denmark methanation process (TREMP technique),
Catalyzer temperature-elevating, reduction in the HICOM technique of above-mentioned Britain or the TREMP technique of Denmark are adopted
The heat form that goes into operation be electric heater or go into operation heating furnace.And in synthesis SNG device, adopt
Go into operation before catalyst is gone into operation by mode of heating by both and heat up, reduce, all there is operating process
Middle security risk coefficient is relatively low, energy waste serious, it is unreliable to run, product fails to domesticize, prolong
The late problem such as dumb in on-stream time, operating process, and restricted application, such as go into operation heating
Stove or electrical heating go into operation heater be substantially not suitable in the synthesis SNG device that explosive-proof grade is higher grasp
Make.Therefore, currently also need to continue to research and develop the safer firing equipment that goes into operation efficiently.
