WebGas Savings = (High-bleed, scfh) — (Low-bleed, scfh) Annual Gas Savings = Gas Savings (scfh) * 8,760 hrs/yr * 1 Mcf/1000scf * $3.00/Mcf Step 4: Evaluate the economics. The cost-effectiveness of replacement, retrofit, or maintenance of high-bleed pneumatic devices can be evaluated using straightforward economic analysis. Web3 de mar. de 1997 · Abstract. High pressure natural gas is often used in process controllers in the oil and gas production industry. The constant bleed of these controllers emits several hundred standard cubic feet per day of natural gas (95% methane) to the atmosphere. Many new ideas on ways to reduce or eliminate this constant bleed are …
