The Gas Recovery (GR) Option
 |
 |
| Why use gas recovery? |
-
Avoid wasting natural gas reserves
If your current pumps vent to atmosphere, you're probably wasting
millions of cubic feet of your gas reserves each year. If you can
send that gas back to a compressor or to a pneumatic instrument panel,
you save 100% of that gas.
-
Reduce natural gas emissions
The GR Option protects the environment by eliminating injection pump
exhaust. Pneumatic equipment is the largest cause of natural gas emissions
and loss during gas production.
-
ReliabilityThe GR
Option takes advantage of a natural design benefit of the CheckPoint
patented double-acting pilot valve. Therefore, reliability and pump
function are the same as our standard 1250, 1500, 5400 and 8400 Series
. Existing pumps can even be GR retrofitted at the factory.
|
| Back pressure capability |
The patented
GR feature enables gas re-routing and recovery, even
against significant recovery system back pressure. In fact,
depending on the chemical discharge pressure, the recovery pressure can
be as high as 170 psig. No other
injection pump can offer this benefit.
|
| Typical recovery applications |
-
Returning exhaust gas to a gas compressor inlet
-
Feeding existing pneumatic instrument or control systems
-
Re-routing gas outside of sealed enclosures
-
In sour gas conditions, recovering exhausted sour
gas to a separate H2S scavenger system (all pump components are NACE
MRO 175 compliant)
-
Running catalytic gas heaters
-
Venting to a flare stack header
-
Re-injecting driver gas on odorization systems
|
| If you use natural gas to run your injector |
-
Route GR exhaust to a lower-pressure gas system as
in the examples above, OR
-
Route GR exhaust gas outside an enclosure where natural
gas buildup must be prevented. A GR pump will work for less than an
equivalent electric pump and is intrinsically safe.
