DESIGN SERVICE CONDITIONS

Sertco Industries Model 98 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.

Scrubber / Blowcase Manufactured by GSM

ASME carbon steel code stamp vessel
Combination scrubber/blowcase handling up to 30 BPD fluids
Mesh pad type elements (304SS) installed
High fluid level shut-down switch
Fluid level sight glasses
Automated dump valve system
Manual drain valve
Heat traced skirt section

PACKAGE FEATURES

3/8" plate structural skid with 35 gallons fluid containment capacity
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 25-35 bbl/day fluid handling capability with the optional 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%
30, 60 and 90 day service schedule based on load, RPM and gas composition
5 gallon oil day tank and automatic level controllers provides make-up oil to both driver and compressor.
Optional custom powder coated trailer with single axle electric brake system and integrated leveling jacks eliminates site preparation and provides an easy method of transporting compressor.
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.
