Drip Blowing Calculator
Calculates time and gas volume required to blow liquids from drip legs and low-point drains. Essential for pipeline commissioning and maintenance of liquid collection systems.
Calculation Mode:

Single Event Data

blows
blows
gallons

๐Ÿ“Š Industry Standard Loss Factors

Wet Blow Loss
Factor: 1.0 MCF per blow
Represents: Gas displaced by liquid during blow-down
Dry Blow Loss
Factor: 5.0 MCF per blow
Represents: Gas vented after liquid removal (higher volume)
Liquid Removal Loss
Factor: 0.025 MCF per gallon
Represents: Dissolved gas in removed liquid
Note: These factors are industry-standard estimates. Actual losses may vary based on system pressure, temperature, and gas composition.

โœ“ Operational Best Practices

๐Ÿ“… Regular Schedule
Establish routine drip blowing intervals based on liquid accumulation rates to prevent over-filling and minimize emergency venting
๐ŸŽฏ Minimize Dry Blows
Optimize blow timing and valve operation to reduce unnecessary dry blows, as they contribute 5x more gas loss than wet blows
๐Ÿ“Š Track & Report
Maintain accurate records of blow counts and volumes for regulatory compliance and loss accounting
โ™ป๏ธ Consider Recovery
For high-volume operations, evaluate closed-loop recovery systems or vapor recovery units to capture vented gas

โš™๏ธ Common Applications

โ€ข Pipeline Drip Legs: Low-point condensate collection in transmission lines
โ€ข Compressor Stations: Scrubber and separator drains
โ€ข Meter Stations: Filter separator liquid removal
โ€ข Gathering Systems: Production well site drips and traps
โ€ข Gas Plants: Inlet separation and knockouts
โ€ข Commissioning: Hydrotest water and construction debris removal
โš ๏ธ Safety Reminder: Always follow company procedures, wear appropriate PPE, and ensure proper venting to safe locations away from ignition sources.
