Copeland Scroll®

Modular Compression For Oil & Gas

Copeland Scroll® gas compression is an exceptionally low maintenance, compact, rugged new approach to oilfield gas compression. The scroll compressor module comes equipped with many high quality features typically found only on larger oilfield compression packages. Packaged flow rates are 15-600 mcfd (0.4-17 mcmd), 60-300 psig single stage discharge pressure (4-21 bar), vacuum to 65 psig suction (0-4.5 bar suction).

Features Once Per Year Maintenance –Simple annual maintenance

for most applications (depending on inlet gas composition and operating conditions) involves changing oil and two filters. Hermetic compressor design eliminates belt tightening, periodic mechanical alignments and interim oil additions. No compressor parts to wear out.

Oilfield Construction – Cold rolled steel housing, cast gray iron scroll compressor elements, stainless steel tubing, swage type steel fittings, welded aluminum oil cooler, approved for use in Class I, Division II applications, CRN certification.

Fewest Service Parts – Minimized service parts requirements reduces inventory costs. Simplicity of service greatly reduces operator/technician training and helps increase workforce productivity.

Applications Flexibility – Optimize horsepower by putting modules in parallel, matching horsepower to required flow rates and pressures. Variable speed capability enables compressors to control flow or pressure set points.

Self Contained Modules – Factory built modules ship complete with compressor/motor, oil cooler/fan, full oil charge, two stage oil separation, pressure and temperature shutdowns, controls and power pre-wired to junction boxes.

Lowest Emissions – Hermetic compressor design (no shaft seals) eliminates oxygen, oil and gas leak paths. Commercial air conditioning noise levels allow for installation in environmentally sensitive areas.

Notes: 1. Operating maps denoted by bold lines 2. All modules capable of continuous 100% flow bypass of discharge gas back to suction without shutting down on

high temperature. Factory-installed gas bypass valve is optional. 3. Standard test conditions: 60F (15.6C) suction gas, 60F (15.6C) ambient, 0.6 specific gravity gas, 14.7 psia = 0

psig, 80 Hz compressor speed. Copeland Scroll Gas Compression Module Performance Program should be used to estimate performance based on actual operating conditions.

4. SZO22C3A-EDE-234 and SZO44C1A-EDE-130 modules are limited to a maximum of 10 PSIG (0.69 bar) suction pressure as built, however a maximum of 25 PSIG (1.72 bar) suction pressure is achievable with a different low pressure switch. SZV56C1A-EDE-110 module is limited to a maximum of 10 PSIG (0.69 bar) suction pressure as built, however a maximum of 30 PSIG (2.07 bar) suction pressure is achievable with a different low pressure switch.

5. Operating any module with suction pressure in a vacuum achievable with a different low pressure switch.

CAUTION: Operating maps could be limited by suction gas temperature due to concerns over dewpoint control. Please consult Copeland Scroll Gas Compression Module Performance Program should be used to estimate performance based on actual site operating conditions to determine if the module is suitable for the application.
