Description
Technical field
The utility model belongs to chemical industry technical field of processing equipment, particularly relates to a kind of butylene isomerization processes compression piece-rate system.
Background technology
The general inter-stage of existing butylene isomerization processes compression piece-rate system arranges cooler, knockout drum, after one stage of compression rich gas through supercooling laggard enter knockout drum, tank deck gas enters two-stage compression, and at the bottom of tank, liquid throws weight-removing column into through booster pump; Rich gas after two-stage compression often throws weight-removing column into through booster pump after subcooler, knockout drum.Such piece-rate system process CIMS is complicated, and energy consumption is high, invests also high.
Summary of the invention
The utility model provides a kind of butylene isomerization processes to compress piece-rate system, and to solve, the flow process proposed in above-mentioned background technology is complicated, energy consumption is high, invest high problem.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of butylene isomerization processes to compress piece-rate system, it is characterized in that: comprise rich gas compressor, weight-removing column, described rich gas compressor is two stages of compression, be respectively one stage of compression device, two-stage compression device, described one stage of compression device, the first connecting pipe is connected with between two-stage compression device, and do not cool, described one stage of compression device one end is connected with product feed pipe, described product feed pipe is connected with product feed arrangement, described two-stage compression device is connected with the second connecting pipe, described second connecting pipe is connected with weight-removing column and is connected to the side of weight-removing column, described weight-removing column top is connected with isomery carbon four discharge line, described isomery carbon four discharge line is connected with isomery carbon four discharger, heavy constituent discharge line is connected with bottom described weight-removing column, described heavy constituent discharge line is connected with heavy constituent discharger.
Described rich gas compressor is symmetrical balance two row two-stage reciprocal water-cooled piston formula compressor.
The beneficial effects of the utility model are:
The capital equipment of the technical program is rich gas compressor and weight-removing column, product directly enters two-stage compression after one stage of compression, inter-stage does not have cooler and knockout drum, can save recirculated water like this, reduce number of devices and then reduce investment, rich gas directly enters weight-removing column with gas phase state after two-stage compression, without cooler and knockout drum, this not only can save recirculated water and weight-removing column steam, and all right simple flow, reduces investment.
Compared with existing compression piece-rate system, the technical program decreases 2 tanks, 2 heat exchangers and 4 pumps, simplifies flow process, see subordinate list 1, for 360,000 tons/year of isomerization of butene devices, recirculated water 13.3t/t raw material can be saved, steam saving 0.21t/t raw material, altogether investment reduction 600,000 yuan.
