How These Compressors Work & Where They Are Used<\/h2>\n
\n
\n
\u2699\ufe0f<\/div>\n

\u5f80\u5fa9\u30d4\u30b9\u30c8\u30f3\u5727\u7e2e<\/h3>\n

The majority of models in this range use balanced-opposed or L-type piston-cylinder arrangements. Gas enters the suction manifold during the piston’s return stroke and is compressed to the target discharge pressure during the forward stroke. Multi-stage configurations cool the gas between stages using intercoolers, reducing work input and preventing thermal degradation of valve seats and piston rings. Valve materials are selected based on gas composition \u2014 stainless steel or titanium plates are standard for hydrocarbon streams.<\/p>\n<\/div>\n

\n
\ud83d\udd35<\/div>\n

Diaphragm Compression (BOG)<\/h3>\n

The D186H70-220 diaphragm BOG compressor operates on a hydraulically actuated metallic membrane that separates the hydraulic fluid from the process gas entirely. This creates a hermetically sealed gas path \u2014 critical for LNG boil-off recovery where even trace quantities of lubricant can foul the re-liquefaction heat exchangers or violate product quality agreements. The diaphragm assembly is inspection-accessible without removing the compressor from the piping system.<\/p>\n<\/div>\n

\n
\ud83c\udfed<\/div>\n

Typical UK Application Scenarios<\/h3>\n

These machines are installed across a variety of UK and European energy projects: onshore LNG peak-shaving plants, industrial gas distribution terminals, offshore platform gas lift and injection systems, LNG bunkering facilities at UK ports, and chemical plant refrigeration loops where hydrocarbon mixed refrigerants replace CFC-based systems. Each installation is subject to site-specific HAZOP and ATEX zoning documentation which our engineering team can support.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

Why UK Plant Engineers Specify Our LNG Compressors<\/h2>\n
\n
\n
\ud83d\udee1\ufe0f<\/div>\n

ATEX-Ready Hazardous Area Design<\/h3>\n

Every machine in the LNG compressor range is designed from the ground up for Zone 1 and Zone 2 classified areas. Electrical components, instrumentation, and control panels are specified to IECEx\/ATEX Group IIA\/IIB standards, meeting UK DSEAR 2002 requirements for facilities handling flammable gases above their lower explosive limit.<\/p>\n<\/div>\n

\n
\ud83d\udcd0<\/div>\n

Pressure Range Up to 32 MPa<\/h3>\n

A discharge pressure ceiling of 32 MPa means these compressors cover the full spectrum of LNG plant duties \u2014 from low-pressure BOG recovery at sub-atmospheric inlet conditions all the way to high-pressure gas injection and cascade refrigerant compression. This eliminates the need to source separate equipment from different vendors for different pressure duties within one plant.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/div>\n

Full Customisation & Aftermarket Support<\/h3>\n

No two LNG plants are identical. Our applications engineering team reviews your process data sheet, utility conditions, and plot plan to produce a matched compressor configuration \u2014 including cylinder sizing, valve trim, crankshaft material, piston rod seal arrangement, and lube oil system design. Spare parts kits, field commissioning, and remote diagnostics are available to UK buyers through our European technical support network.<\/p>\n<\/div>\n

\n
\u26a1<\/div>\n

BOG Compressor Retrofit Reduces Flaring by 94% at Scottish Terminal<\/h3>\n

A gas distribution terminal near Aberdeen was experiencing unacceptable boil-off losses from its cryogenic storage tanks during summer months when regasification demand dropped and storage levels remained high. The terminal was venting and flaring boil-off gas (BOG) rather than recovering it, incurring both commodity losses and increasing regulatory pressure from the Scottish Environment Protection Agency (SEPA). The plant manager engaged our engineering team to evaluate replacement of the existing ageing reciprocating BOG compressor \u2014 a unit that was undersized for the current storage inventory \u2014 with the DW-22\/25 BOG Compressor. Following a detailed process audit and compressor sizing calculation against the terminal’s maximum BOG generation rate of 18 Nm\u00b3\/min at 0.05 MPa suction, we supplied and commissioned the DW-22\/25 within an eleven-month EPC cycle. Post-commissioning measurements confirmed a 94% reduction in vented and flared BOG, with the recovered gas being reinjected into the high-pressure send-out header. The terminal operator reported annual gas recovery savings exceeding the full capital cost of the compressor package within the first twenty months of operation.<\/p>\n

Voice-search and conversational queries from UK plant engineers and procurement teams.<\/p>\n

\n
\nWhich natural gas compressor models are suitable for LNG liquefaction plants operating in the United Kingdom and what are typical lead times for delivery? +<\/span><\/summary>\n

All seven models in our LNG compressor range \u2014 including the DW-30\/15-52, 4MW-36\/24-70, DW-21.4\/2.9-23, and DW-22\/25 \u2014 are suitable for UK LNG facilities and carry CE and UKCA marking. Standard lead times from order placement to factory acceptance test range from 18 to 32 weeks depending on machine size and customisation level. Contact our team for a project-specific schedule.<\/p>\n<\/details>\n

\nHow much does a BOG compressor cost for a UK LNG terminal and can you provide a budgetary price before a full technical enquiry? +<\/span><\/summary>\n

BOG compressor pricing depends heavily on flow rate, suction pressure, discharge pressure, ATEX category requirement, and skid scope (bare shaft, package, or fully integrated). We can provide a budgetary price range within 5 working days of receiving a one-page process data sheet. Email sales@\u30ec\u30fc\u30b6\u30fc\u30ab\u30c3\u30bf\u30fc\u7528\u30a8\u30a2\u30fc\u30b3\u30f3\u30d7\u30ec\u30c3\u30b5\u30fc.com<\/a> with your BOG rate and conditions to start the conversation.<\/p>\n<\/details>\n

\nWhat certifications do your LNG compressors hold and are they compliant with UK DSEAR and PSSR 2000 regulations for hazardous area installations? +<\/span><\/summary>\n

Yes. All machines are designed to comply with UK PSSR 2000 (Pressure Systems Safety Regulations) and DSEAR 2002 (Dangerous Substances and Explosive Atmospheres Regulations). Documentation provided includes CE\/UKCA Declaration of Conformity, ATEX certificate for electrical components (IECEx-equivalent), materials certification to EN 10204 3.1, and hydrostatic test certificates. We work with UK Notified Bodies and can adapt documentation to specific client requirements.<\/p>\n<\/details>\n

\nWhere can I find a reliable supplier of diaphragm BOG compressors for high-purity LNG applications in Scotland or the North of England? +<\/span><\/summary>\n

The D186H70-220 diaphragm-type BOG compressor is our recommended solution for high-purity LNG vapour recovery where zero oil contamination is required. We supply this model to facilities across the UK including Scotland, the Humber estuary, and South Wales. Our European logistics partners handle export documentation and coordinate delivery to UK terminal sites on a project-by-project basis.<\/p>\n<\/details>\n

\nHow does the mixed refrigerant compressor handle fluctuating suction conditions in an SMR liquefaction cycle during winter operating periods in the UK? +<\/span><\/summary>\n

The 4MW-48\/2.6-29 is designed with suction pressure and temperature flexibility built into the cylinder sizing. During UK winter conditions, when ambient temperature drops improve compressor volumetric efficiency and refrigerant density changes, the machine can be unloaded via stepless capacity control or adjustable clearance pockets to maintain stable discharge conditions without risking liquid carry-over into the cylinders. Contact us for winter\/summer performance curve sets.<\/p>\n<\/details>\n

\nWhat is the difference between the DW-22\/25 and the D186H70-220 BOG compressor and which one should I specify for my LNG storage tank application? +<\/span><\/summary>\n

The DW-22\/25 is a piston-type BOG compressor with a lubricated cylinder \u2014 suited to large tank farms where throughput is the primary constraint and minor oil carry-over to the downstream system is tolerable or manageable through coalescing filters. The D186H70-220 is an oil-free diaphragm design \u2014 the right choice when downstream equipment (heat exchangers, molecular sieves, or send-out gas specs) cannot tolerate any lubricant. We recommend the D186H70-220 for high-purity or re-liquefaction duty and the DW-22\/25 for high-flow gas return applications.<\/p>\n<\/details>\n<\/div>\n
