제품 개요

그만큼 DW-100/8 nitrogen compressor represents the pinnacle of our oil-free piston compressor engineering, occupying the ultra-high-capacity segment of our industrial nitrogen booster portfolio. With an extraordinary 100 m³/min capacity 강력한 것과 짝을 이룬다 0.80 MPa 토출 압력, this unit is engineered to serve the most demanding nitrogen distribution requirements in mega-scale industrial gas infrastructure worldwide.

What fundamentally distinguishes the DW-100/8 from all conventional alternatives is its completely oil-free compression pathway. The piston rings and rider bands are fabricated from proprietary self-lubricating PTFE composite materials that operate without any hydrocarbon lubricants whatsoever. This intrinsic oil-free architecture guarantees the nitrogen product stream remains absolutely uncontaminated, achieving ISO 8573-1 클래스 0 인증 without any downstream purification equipment. For operators across food processing, pharmaceutical manufacturing, electronics fabrication, and petrochemical processing, this eliminates both the capital investment and ongoing operational burden of oil-filtration systems.

The compressor utilizes a 2단 2열(two 列 级) configuration that optimally distributes the substantial pressure ratio across two compression cylinders. This staged thermodynamic approach is critical for managing the thermal loads inherent to 0.80 MPa discharge pressure while preserving the dimensional integrity of the PTFE sealing elements. Each stage incorporates an independent high-efficiency intercooler, ensuring gas temperatures remain well within safe operating envelopes even during sustained maximum-capacity operation. The massive cast-iron frame and dynamically balanced forged steel crankshaft are rated for an exceptional service life of 120,000+ hours under rigorous industrial maintenance protocols.

주요 특징 및 엔지니어링 장점

1. Ultra-High-Capacity Oil-Free Compression

The DW-100/8 employs a proprietary self-lubricating piston ring and rider band system manufactured from advanced PTFE composites reinforced with glass fiber and bronze particulates. This material formulation achieves a coefficient of friction below 0.06 without any external hydrocarbon lubrication, completely eliminating the risk of oil vapor carryover into the nitrogen product stream. At 100 m³/min capacity, even trace oil contamination would represent a massive quality failure. The DW-100/8’s native ISO 8573-1 Class 0 compliance eliminates the need for downstream oil-filtration equipment that would be physically enormous and energy-intensive at this flow scale. The PTFE rings are specifically engineered for the elevated discharge temperatures associated with 0.80 MPa operation, maintaining dimensional stability up to 180°C.

2. Two-Stage Thermodynamic Optimization for High Pressure

그만큼 2단계 압축 아키텍처 of the DW-100/8 is thermodynamically optimized for the demanding 0.80 MPa discharge pressure target. By dividing the substantial overall pressure ratio between a large-bore low-pressure cylinder and a high-pressure cylinder, the compressor achieves a significantly lower mean effective temperature per stage. A massive high-efficiency shell-and-tube intercooler between stages removes the heat of compression, maintaining discharge temperatures below 155°C even at maximum continuous load. This thermal management is absolutely critical for preserving PTFE ring integrity at this capacity and pressure combination, and extends valve plate service life by approximately 40% compared to single-stage designs attempting equivalent pressure ratios.

3. Massive Cast-Iron Frame with Force Balance Engineering

본체는 다음 재료로 주조됩니다. GG25 회주철 (equivalent to ASTM A48 Class 30B) with integral cooling water passages. The 2열 대향 실린더 배열 provides natural first-order force cancellation, reducing the unbalanced inertia forces transmitted to the foundation by over 80% compared to single-row designs. Despite the unit’s substantial 13.00-tonne weight, this mechanical advantage permits installation on a reinforced concrete inertia block of approximately 20 tonnes—significantly lighter than would be required for a single-row compressor of equivalent capacity. The massive frame dimensions of 5456 × 3518 × 2535 mm reflect the engineering requirements of handling 100 m³/min flow while maintaining the precision clearances necessary for oil-free piston operation.

4. High-Power Medium-Voltage Motor Drive

The DW-100/8 is driven by a 600 kW medium-voltage induction motor available in either 6kV or 10kV configurations, conforming to IEC 60034-1 efficiency class IE3. At this power level, medium-voltage drive is not merely preferred—it is essential. A 380V motor would require impractical cable sizes (exceeding 400 mm² cross-section) and massive low-voltage switchgear. The 6kV or 10kV configuration integrates directly into industrial medium-voltage distribution networks, reducing electrical infrastructure costs, minimizing I²R losses in power cabling, and improving overall system energy efficiency. For mega-scale industrial facilities where 6kV or 10kV bus systems are standard, the DW-100/8 offers seamless electrical compatibility.

응용 시나리오

초대형 극저온 공기 분리 설비

In mega-scale cryogenic ASU facilities producing 5,000–15,000 Nm³/h of gaseous nitrogen, the DW-100/8 serves as the 주요 고용량 질소 부스터 between the cold box and the distribution header. Its 100 m³/min capacity matches the output of the largest single-train ASUs, while the 0.80 MPa discharge pressure provides sufficient head for long-distance pipeline distribution to downstream consumers across vast industrial complexes. The oil-free design is absolutely critical in these applications because any oil contamination would compromise nitrogen purity across the entire distribution network, affecting multiple downstream processes including semiconductor manufacturing, pharmaceutical production, and food processing facilities served by the same header.

Large VPSA Nitrogen Booster Stations

대기압에 가까운 압력에서 99.5~99.9% 순도의 질소를 생산하는 대형 VPSA 질소 발생기의 경우, DW-100/8 nitrogen booster compresses the low-pressure product to 0.80 MPa for high-pressure distribution across extensive industrial campuses. The 100 m³/min capacity can serve multiple large VPSA trains simultaneously, or provide redundancy for critical nitrogen supply systems. The oil-free compression path is non-negotiable in VPSA service because hydrocarbon contamination would irreversibly poison the carbon molecular sieve adsorbent, degrading separation efficiency across the entire generator system and necessitating costly adsorbent replacement that could exceed $200,000 for large installations.

Petrochemical Complex High-Pressure Nitrogen Distribution

In integrated petrochemical complexes, the DW-100/8 provides the backbone of the high-pressure nitrogen distribution infrastructure. The 0.80 MPa discharge pressure is sufficient to overcome pipeline friction losses across multi-kilometer distribution networks, serving dozens of process units including ethylene crackers, polyethylene reactors, aromatics complexes, and sulfur recovery units. The 100 m³/min capacity can support simultaneous nitrogen demands from multiple process units during startup, shutdown, and emergency inerting procedures. The oil-free certification is mandatory because nitrogen contacts catalyst beds, enters process streams, and provides blanketing for sensitive chemical storage—all of which must remain absolutely hydrocarbon-free.

LNG Liquefaction & Regasification Terminal Nitrogen Supply

LNG terminals require enormous volumes of nitrogen for pipeline purging, tank inerting, and emergency nitrogen injection into cryogenic storage tanks. The DW-100/8’s 100 m³/min capacity can maintain nitrogen supply during the most demanding operational scenarios, including full-terminal nitrogen purge operations that may require continuous high-flow nitrogen for several days. The 0.80 MPa discharge pressure provides adequate head to overcome the hydrostatic pressure of LNG storage tanks and maintain positive inert gas pressure throughout the terminal’s distribution network. The oil-free design prevents hydrocarbon contamination of LNG product, which would compromise cryogenic properties and violate LNG quality specifications.

자재 및 시공

The DW-100/8 is constructed from premium materials selected for nitrogen compatibility, high-pressure service, and extended operational life at ultra-high capacity:

모든 압력 지지 부품은 다음 사항에 따라 엄격하게 설계 및 제작됩니다. ASME BPVC 섹션 VIII 부문 1 또는 중국 GB 150 표준을 준수합니다. 모든 용접 이음매는 ASME 섹션 V, 2항에 따라 100% 방사선 투과 검사(RT)를 거치며, 완성된 모든 압력 용기는 최대 허용 작동 압력(MAWP)의 1.5배에 해당하는 압력으로 최소 30분 동안 수압 시험을 거칩니다.

설치 및 유지 관리 지침

기초 및 구조 요구사항

The DW-100/8 has a dry weight of 13.00 tonnes and a center of gravity approximately 1,000 mm above the baseplate. Despite its massive scale, the two-row opposed-cylinder design minimizes unbalanced forces, permitting installation on a reinforced concrete inertia block of 20–25 tonnes. The block must be mounted on heavy-duty elastomeric vibration isolators (natural frequency 5–7 Hz) to prevent vibration transmission to adjacent structures and sensitive instrumentation. Minimum clearance requirements: 2.0 m on the non-drive side for valve access, 1.5 m on the drive side for motor maintenance, and 2.5 m overhead for crane access during major overhauls. Given the unit’s dimensions of 5456 × 3518 mm, the compressor house must provide adequate clearance on all sides for safe operation and maintenance.

냉각수 시스템 설계

냉각수 수요는 대략 다음과 같습니다. 100 m³/h at an inlet temperature not exceeding 32°C. The water distribution circuit supplies the cylinder jackets, intercooler, and aftercooler in parallel branches with individual flow control valves. Water quality specifications: pH 6.5–8.5, total dissolved solids < 500 mg/L, chloride content < 50 mg/L (to prevent SS316 tube corrosion in the coolers), suspended solids < 30 mg/L, and total hardness < 300 mg/L as CaCO₃. Given the massive cooling water requirement, a dedicated closed-loop cooling tower with side-stream filtration, chemical treatment, and a 10 m³ buffer tank is strongly recommended. The cooling water system must be designed with redundancy to ensure continuous operation during cooling tower maintenance.

예방 정비 일정

The oil-free design of the DW-100/8 dramatically reduces maintenance complexity compared to lubricated alternatives at this scale. There are no oil changes to schedule (which would require 500+ liters of lubricating oil per change), no oil analysis to perform, no filter elements to replace, and no separator cartridges to monitor. The primary consumable wear items are the PTFE 피스톤 링 및 라이더 밴드, which typically achieve 4,000–6,000 hours of service life under clean nitrogen conditions. At 100 m³/min capacity, the elimination of oil-related maintenance represents annual savings of $50,000–$80,000 compared to lubricated alternatives.

규정 준수 및 안전 인증

The DW-100/8 nitrogen compressor is designed, manufactured, and tested to meet or exceed the following international standards and regulatory frameworks:

성과 및 효율성 분석

The DW-100/8 achieves a specific power consumption of approximately 6.00 kW per m³/min of nitrogen delivered at 0.80 MPa discharge pressure. This efficiency metric is exceptional for an ultra-high-capacity oil-free piston compressor operating at an elevated pressure ratio. For context, oil-lubricated screw compressors in similar mega-scale applications typically consume 6.5–7.5 kW/m³/min, while attempts to use multiple smaller compressors in parallel introduce additional inefficiencies from part-load operation and distribution losses.

Over a standard 8,000-hour annual operating schedule, the DW-100/8’s efficiency advantage generates approximately 400,000–1,200,000 kWh of annual energy savings compared to less efficient alternatives or parallel compressor arrangements. At an average industrial electricity tariff of $0.08/kWh, this represents $32,000–$96,000 in direct operating cost reduction per year. When combined with the complete elimination of oil-related consumables (which would be massive at 100 m³/min scale), the 질소 압축의 총 소유 비용 is reduced by an estimated 25–35% over a 10-year operational life.

The absence of oil in the compression path eliminates the energy penalty and physical space requirements of downstream oil-removal equipment. At 100 m³/min, a typical oil-lubricated compressor would require multiple large coalescing filters, activated carbon adsorber vessels, and continuous oil monitoring instrumentation that would collectively consume 3–5% of the compressor’s power output and occupy significant floor space. The DW-100/8’s oil-free design removes this parasitic load and spatial burden entirely.

Case Study: Mega-Scale Petrochemical Complex Nitrogen Infrastructure

고객: A world-scale integrated petrochemical complex in the Middle East with ethylene, polyethylene, and aromatics units

도전: The complex’s nitrogen supply was provided by three aging oil-lubricated compressors (European brand, 20+ years in service) operating in parallel to achieve the required 90 m³/min flow. The system was experiencing chronic oil carryover (5.1 mg/m³ average), causing catalyst poisoning in the ethylene cracker, product contamination in polyethylene pelletizing, and frequent unplanned shutdowns for oil-related repairs. Total maintenance costs had reached $180,000/year, and the 0.60 MPa pressure was insufficient for new high-pressure reactor inerting requirements.

해결책: We supplied a DW-100/8 oil-free nitrogen compressor as the primary nitrogen supply, replacing two of the three aging compressors. The unit was configured on a custom skid with integrated intercooler, aftercooler, and a Siemens S7-1500 PLC control panel with full SCADA integration. The 0.80 MPa discharge pressure met all new high-pressure inerting requirements, while the 100 m³/min capacity provided redundancy margin above the complex’s peak demand of 85 m³/min. A 10 m³ surge vessel was installed upstream to buffer demand fluctuations from multiple process units.

Quantified Results After 30 Months:

• 질소 오일 함량: Reduced from 5.1 mg/m³ to <0.01 mg/m³ISO 8573-1 클래스 0 인증을 획득했습니다.
• Ethylene cracker catalyst poisoning incidents: 완전히 제거됨, extending catalyst life from 24 months to 36 months
• 연간 유지 관리 비용: 48%만큼 감소 ($180,000 to $93,600) through elimination of oil-related repairs
• 에너지 소비량: 8.2%만큼 개선됨 versus the replaced compressors, saving approximately $38,400/year
• 예기치 않은 다운타임: 이벤트 없음 in 30 months of continuous operation
• Compressor count: Reduced from three units to one primary unit plus one standby, simplifying operations and reducing spare parts inventory by 60%

“The DW-100/8 has been a game-changer for our nitrogen infrastructure. The single high-capacity unit replaced three aging compressors, eliminated oil contamination completely, and reduced our maintenance team workload by half. The payback period was 16 months—far better than our initial projections.” — 석유화학 단지 최고운영책임자
