China in Recent Years natural gas liquefaction plant is always towards scale, integrative development, but China to have more than the Distribution of Natural more than 50% in the Sichuan Basin, Tarim Basin In Xinjiang, the west areas such as Shan Gan Ning.Have inconvenient traffic, lack storage facility, collect defeated high cost, greatly limit these regional gas extraction and utilizations.
Summary of the invention
The gas production existed for above-mentioned remote districts is had inconvenient traffic, is lacked the problem such as storage facility, the defeated high cost of gas production collection, the invention provides a kind of miniature movable type skid LNG liquefying plant, its account for foundation-free, ground area little, can whole sled dismounting transport, do not need the advantage of LNG product storage tank.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of miniature movable type skid LNG liquefying plant; Comprise purification sled; Dehydration sled; Liquefaction sled; Cryogen sled and public work sled; It is characterized in that purification prizes gas pipeline and prizes air inlet be connected with dehydration, dehydration prizes gas pipeline with liquefying and prizes admission line and be connected, liquefaction sled cryogen recovery line and cryogen are prized cryogen and are reclaimed import and be connected, cryogen sled benefit refrigerant line is prized cryogen import with refrigerant compressor and is connected, refrigerant compressor sled cryogenic coolant outlet line is prized cryogenic coolant import with liquefaction and is connected, liquefaction sled high temperature cryogen outlet line is prized the import of high temperature cryogen with refrigerant compressor and is connected, and public work sled instrument airduct line is connected with the instrument airduct line that each is prized; Public work is prized public nitrogen pipeline and is prized public nitrogen inlet with refrigerant compressor and be connected.
Wherein purification sled instrument airduct line, dehydration sled instrument airduct line, liquefaction sled instrument airduct line are prized instrument airduct line with cryogen sled instrument airduct line (12) parallel connection with public work and are connected.
All sled interblock pipelines use flange docking.
Skid steel construction uses H profile steel welding, and steel construction is equipped with instrument and appliance wiring groove box.
Unstripped gas enters purification sled through unstripped gas pipeline, unstripped gas enters dehydration sled through purified gas pipeline (4) after purification sled depickling decarburization, purified gas enters liquefaction sled through dry gas pipeline after sled dehydration of dewatering, and liquefies in dry gas liquefies and prizes with after cryogen heat exchange throttling; Cryogen enters ice chest after refrigerant compressor pressurization and heat exchange gas carries out first time heat exchange, cryogen through heat exchange cooling is lowered the temperature further by choke valve, cryogen through throttling cooling enters cryogenic coolant runner and carries out second time heat exchange, and after cryogenic coolant carries out second time heat exchange, intensification returns refrigerant compressor; Public work sled by instrument wind give vent to anger pipeline give each sled instrument general mood body and public nitrogen are provided.
Be bolted between above-mentioned purifier, dehydration sled, cold compressor sled, liquefaction sled four sled, all sled interblock pipelines use flange docking, prize block wiring except outer other of compressor sled block and all use snap joint to connect; Skid steel construction uses H profile steel welding, and steel construction is equipped with instrument and appliance wiring groove box, and steel construction size adjusts according to instrument size.
The invention has the beneficial effects as follows: by becoming sled to the integrated optimization of process unit, process unit floor space is greatly reduced; Construction period is short, and miniature movable type skid LNG liquefying plant in-site installation quantities is little, and the construction period is short, under normal circumstances, and 6-8 month just can finished item construction; Manipulation is convenient, and whole process unit makes integral constructing structure quite compact by integrated, modularized design, allows equipment control to become easier, thus is convenient to administering and maintaining of equipment; By counterweight, each sled can greatly be reduced by foundation-free to site requirements, general compacting is smooth, produces very favourable to field transition; Be bolted between dehydration sled, cold compressor sled, liquefaction sled four sled, all sled interblock pipelines use flange docking, and except compressor sled block, other sled block wiring all uses snap joint to connect, and these all make dismounting between sled more convenient; By making production equipment can along with each sled whole Transporting to process unit modularization integrated one-tenth sled, the flexibility of resettlement transition transport be stronger; Without LNG product storage tank and heavy hydrocarbon storage tank, fixed investment is greatly reduced, resettlement transition is easier.
