DESIGN SERVICE CONDITIONS

Sertco Industries Model 350 Series compressors are designed to handle a wide variety of conditions in wellhead compression. Specific applications are designed using known well data such as suction and discharge pressures, suction temperatures, the anticipated amount of fluids and desired gas flow.

SUCTION SCRUBBER
ASME 500 PSI 20" O.D. X 52" SUCTION SCRUBBER / BLOWCASE

ASME carbon steel code stamp vessel
Combination scrubber/blowcase handling up to 100 BPD fluids
Mesh pad type elements (304SS) installed
High fluid level shut-down switch
Kenco high pressure sight glasses with ball checks
Automated dump valve system
Manual drain valve

AIR COOLER
ASME Induced Draft AC/EJW stacked oversized Cooler
Process Gas / Engine Water Cooler

Air Cooled Heat Exchanger Manufactured by AXH including:
EJW (Water) and AC (Gas) cooling sections supplied as follow:

Designed for 20 F approach temperature
Manual individual gas louvers

High temp - compressor discharge - left bank
High temp - compressor discharge - right bank
High temp - engine jacket water
High level - scrubber
High/Low level - engine oil
High/Low level - compressor oil
Low level - engine water
Vibration - compressor
Emergency stop - local – push button on panel
Overspeed (integral to annunciator) - signal from magnetic pick-up

DISCRETE ANNUNCIATOR CONTROL OUTPUTS

Mode selector switch - idle / manual / auto
Manual speed potentiometer
Unit panel power switch - off/on - on panel insert.

PACKAGE FEATURES

3/8" plate structural skid with 80 gallons fluid containment capacity
Hospital grade, flame arresting lifetime muffler design
CNC machined skid brackets and details for perfect fit and interchangeability
Suction control valve with positive shut-off system when compressor shuts down
ASME code scrubber/blowcase with up to 100 - 300 bbl/day fluid handling capability with the ability to re-inject the fluids into the discharge gas stream. System designed for maximum efficiency adapting to fluctuating discharge pressure conditions with increased discharge pressure only when needed for the dump cycle.
Engine jacket water heat trace system prevents liquid from freezing in blow case.
Process piping constructed with S 80 A106 grade B seamless carbon steel pipe with carbon content < .43%
ASME code oversized gas aftercooler designed for 20 F maximum discharge temperature above ambient temperature under all operating conditions
Standard oversized engine jacket water cooler for ambient conditions up to 105 F
Driveshaft coupling between compressor and driver eliminates the need for alignment procedures and is designed to break and protect the compressor if it receives liquid in the suction. Also allows for compressor/driver replacement in the field in less than 4 hours.
Puller fan, roof and heat trace system prevent freezing of piping, tubing and vessels on skid with ambient temperature @ -20 F
30, 60 and 90 day service schedule based on load, RPM and gas composition
Heated 25 gallon oil daytank and automatic level controllers provides make-up oil to both driver and compressor for 90 days
Optional custom powder coated trailer with dual-axel electric brake system and integrated leveling jacks eliminates site preparation and provides an easy method of transporting compressor with ½ ton truck.
Optional integrated, removable roof structure with hinged side panels protects all belts and hoses from UV rays and protects the skid from collecting rain water and potential oil spills
Optional low suction pressure make-up system prevents unnecessary shut-downs when gas flow rate fluctuates. System also prevents vacuum operation if desired.
Optional package bypass system allows gas production to continue if the compressor shuts down.
