Description
Technical field
The utility model relates to a kind of energy conserving system in petrochemical technology field, particularly a kind of gas separation unit mass transport energy conserving system.
Background technology
During petrochemical complex is produced, blue gas disengagement gear is that gas separation unit generally comprises depropanizer system, deethanizer system, propylene tower system.Its product propylene, propane are delivered to tank field by product pump.Processing capacity is the gas separation unit of 22.4 ten thousand tons/year, and propylene product pump, propane product pump consumption of current every day reach 1056 degree, and annual consumption of current reaches 38.54 ten thousand degree.So to cause gas separation unit product to deliver to the energy consumption of tank field outward high for high consumption of current, and device tooling cost is high, greatly reduces the economic benefit of device.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the existing gas separation unit product existing in background technology to deliver to the high problem of the high device tooling cost of tank field energy consumption outward, and provide a kind of gas separation unit mass transport energy conserving system, this gas separation unit mass transport energy conserving system, can reduce gas separation unit product and deliver to tank field energy consumption outward, reduce the problem of device tooling cost.
The invention for solving the technical problem can reach by following technical solution: this gas separation unit mass transport energy conserving system, comprise propylene tower, reflux accumulator, described propylene tower overhead line is connected to reflux accumulator tank deck, on reflux accumulator tank bottom tube line, connect pump A, pump A discharge pipe is connected to tank field, is connected to the outer flow counter A of putting on pump A discharge pipe; Reflux accumulator tank bottom tube line is connected with on pump A discharge pipe the pipeline cross-line A and the valve that stride across pump; On described propylene tower tower bottom tube line, connect pump B, pump B discharge pipe is connected to tank field, is connected to the outer flow counter B of putting on pump B discharge pipe; Propylene tower tower bottom tube line is connected with on pump B discharge pipe the pipeline cross-line B and the valve that stride across pump.
The utility model is compared and can be had following beneficial effect with above-mentioned background technology: this gas separation unit mass transport energy conserving system is owing to adopting above-mentioned flow process, realized product send outside pressured poor, need not electric conversion of energy, saved a large amount of electric energy.Greatly reduce gas separation unit product and deliver to the tooling cost of tank field energy consumption and device outward.
brief description of the drawings:
Accompanying drawing 1 is schematic flow sheet of the present utility model.
In figure: 1-propylene tower, 2-reflux accumulator, 3-pump A, 4-flow counter A, 5-cross-line A, 6-pump B, 7-flow counter B, 8-cross-line B.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this gas separation unit mass transport energy conserving system, comprise propylene tower 1, reflux accumulator 2, described propylene tower 1 overhead line is connected to reflux accumulator 2 tank decks, on reflux accumulator 2 tank bottom tube lines, connect pump A3, pump A3 discharge pipe is connected to tank field, is connected to the outer flow counter A4 of putting on pump A3 discharge pipe; Reflux accumulator 2 tank bottom tube lines are connected with on pump A3 discharge pipe the pipeline cross-line A5 and the valve that stride across pump; On described propylene tower 1 tower bottom tube line, connect pump B6, pump B6 discharge pipe is connected to tank field, is connected to the outer flow counter B7 of putting on pump B6 discharge pipe; Propylene tower tower bottom tube line is connected with on pump B6 discharge pipe the pipeline cross-line B8 and the valve that stride across pump.
This gas separation unit mass transport energy conserving system, because there is difference of pressure in propylene tower operating pressure and tank field pressure.Propylene tower operating pressure, higher than tank field pressure, is opened the valve on cross-line A5 gradually, closes pump A3 outlet valve, and propylene product pump is stopped, and puts flow counter A4 control the propylene amount of releasing outward with former control cock outside regulating; Open gradually the valve on cross-line B8, close pump B6 outlet valve, propane product pump is stopped, outside regulating with former control cock, put flow counter B7 and control propane high-volume outward.Realized product send outside pressured poor, need not electric conversion of energy, saved a large amount of electric energy.
