Technical field
The utility model relates to anti-surge technical field, relates in particular to a kind of butylene skeletal isomerization device compressor anti-surge installation.
Background technique
Isobutylene is industrial chemicals important in petrochemical industry, has MTBE, polyisobutylene, MMA, butyl rubber etc. in the subsequent product of isobutylene.
In industry, the source of isobutylene is mainly steam cracking device and catalytic cracking unit, and therefore the industrial application but the isobutylene amount that said apparatus is produced is also nowhere near adopts butylene skeletal isomerization technology to produce the deficiency that isobutylene supplements isobutylene.
Butylene skeletal isomerization is in liquefied petroleum gas (LPG), to mix carbon four for raw material, under the reaction region of low-voltage high-temperature, reacts.
Owing to being low pressure reaction, and reacted separation needs under certain high pressure to carry out, so in butylene skeletal isomerization device, centrifugal compressor is a capital equipment, and the safe operation of centrifugal compressor is the most important thing.
Traditional anti-surge is compressor outlet material whole condensing coolings rear section or all returns to suction port of compressor, maintains inlet flow rate and be not less than Surging flow.To prevent compressor surge, in this process, compressor will do work to the compression of gaseous state material, pressure rise not only in the process of acting, and temperature also rises, the temperature of Normal squeezing machine outlet is than high tens degree of entrance, and anti-surge is returning suction port of compressor after the decompression of the gas of outlet, being not less than Surging flow to reach suction port of compressor flow, if it is cooling that the gas returning does not carry out, the temperature of suction port of compressor can be more and more higher, finally causes compressor not run well.The conventional practice is that compressor outlet material is all cooling, and wherein a part is as anti-surge flow, and another part is as tower charging.Owing to being by all cooling rear backflows of the material of compressor outlet, waste resource so.
Therefore, how providing a kind of butylene skeletal isomerization device compressor anti-surge installation, with saving resource, is current those skilled in the art technical problems urgently to be resolved hurrily.
