Other - Dehydrators
- Q576. In 98.233(e), is the daily thoroughput for glycol dehydrators based on annual average daily thoroughput?
- Q577. Should the daily throughput for dehydrators in 98.233(e) be re-evaluated annually? If the throughput decreases below the 0.4 MMscf per day threshold, should the equipment be excluded from the Subpart W report?
- Q578. Do dehydrators which are used to dry a liquid stream meet the definition of dehydrator?
- Q579. The emission methods for dehydrator vents with daily throughputs less than 0.4 MMscfd in the preamble (use flow rate of wet NG and EF) contradict the requirements in the rule (use dehydrator count and EF).
- Q580. For glycol dehydrators with annual average daily natural gas throughputs greater than 0 million standard cubic feet (MMscf) per day and less than 0.4 MMscf per day, can GRI-GLYCalc be used instead of Method 2 in 40 CFR 98.233(e)(2)?
- Q581. Under §98.233(e)(1), emissions must be calculated from dehydrator vents with throughput greater than or equal to 0.4 million standard cubic feet per day. Is this throughput specific to vent throughput or dehydrator throughput?
- Q582. For dehydrator wet natural gas sampling, does the 98.233(e)(1)(xi)(A) reference to (u)(2)( i ) refer only this paragraph or all of (u)(2)?
- Q583. Is 98.233(e)(6) supposed to be referring to dehydrators that use desiccant only?
- Q584. Is a software application necessary to calculate dehydrator vent emissions and storage tank emissions if flash gas is being sent to a flare? Can a reporter use engineering calculations and direct measurement to estimate volume to flare?
- Q585. What does EPA mean by "disposition of recovered gas"? Why does EPA think this is a required parameter for the software model?
