In recent years, China's methanol industry from the perspective of the development, good macroeconomic environment and the rapid growth of the downstream demand of China's methanol industry continue to maintain steady and rapid growth, in 2005 the domestic methanol apparent consumption reached 666.20000t, an growth of 16.3% during the period from 1995 to 2005, average annual growth of methanol consumption rate of 15.11%, a good demand environment, the use of methanol market is still in a rapid growth stage. Enter 2006 in the domestic economic situation is excellent, methanol demand growth as well as domestic methanol market impact of skyrocketing prices, the domestic methanol from January to October 2006, the apparent consumption reached 6911000t, year 2005 grew by 21.8% in January-October . Over the previous five-year average annual growth rate increased by 10%. Accelerated growth reasons, routine removal of formaldehyde, acetic acid, MTBE and other industries steadily increasing demand, the growing louder methanol fuel industry should be the main driver of growth in demand.
A) the source of the task
The design of the book according to the task requirements, refer to the actual chemical plant for methanol production while doing an analog design its purpose is the use of chemical engineering knowledge and attempt to conduct a chemical engineering design, and for industrial production of methanol, producing device is designed to provide a reference . As analog design, this article omits part of chemical engineering design, such as process piping design, explosion-proof electrical design, power design
B) design standards.
This design reference to the following national standards and regulations
a. production of dangerous goods and harmful factors in the process of classification and code (GB/T13816-1992)
b. classification of hazardous chemicals commonly used standard (GB13690-1992)
c. typical pressure vessel chemical medium degree of hazard and explosion hazard classification (HGJ43-1991)
d. factory fire regulations (GBJ16-1987)
e. Steel Pressure Vessel (GB150)
f. shell and tube heat exchangers Standard (GB151)
g. process system equipment layout design requirements (HG20570)
h. chemical plant piping design requirements (HG/T20549)
C) design principles
(1) Security: the production of a large number of chemical substances are flammable, explosive or toxic. Therefore, the design must take into account all the obvious and potentially dangerous, to ensure the health and safety of production personnel.
(2) Easy to operate: in determining the various production processes and equipment, but also reasonably determine operating conditions. Because of its production process and equipment to establish its role to play and control program to determine, there is a direct relationship.
(3) Investment Province: that requires economical use of equipment investment, construction investment, public works investment and labor costs.
(4) Ease of Installation: plant layout should meet the construction and installation requirements. Especially should consider lifting large equipment, plant and loads of road pavement structure should meet the standards of construction and installation requirements.
Keyword: Methanol, synthesis, rectification.
