Dalong Machinery works has a long
history of designing and manufacturing various kinds
of reciprocating piston gas compressors. For several
decades we have been providing various delicate
and special compressors for all trades in china,
such as low temperature ethylene compressors for
petrol-chemical industry, composite ethylene compressors
with different suction pressure, hydrogen compressors
for process of chemical industry, air compressors
for process of urea factories, oxygen compressors
for air-separating equipment plant and chlorine
compressor for chlorine-alkali industry etc.
In recent years, we have developed
and variated 2D8 compressor series which can make
use of the limekiln smoke from steel plants, remaining
gas from petrol-chemical factories and flashing
evaporant from synthetic ammonia plants etc. To
recover useful gas with technological methods, such
as changing pressure, adsorption etc. In this way,
useful gas can be recovered by some special processes.
So wastes will be converted into useful materials
and profit can be gained from economies.
