Control separation nitrogen pressure using a differential pressure transmitter sensing
secondary vent pressure to ensure a nitrogen atmosphere between the secondary seal and separation seal to positively prevent a hydrocarbon release to the plant environment.
Under the new Clean Power Plan, the EPA calculates state goals based on the Best System of Emission Reduction (BSER), and has now established separate emissions performance rates for coal and natural gas plants, as follows:
General Electric’s Schenectady-based Power&Water unit recently won 4 HA gas turbine
orders during the third quarter of the year, the company said. The orders were in Pakistan, South Korea and in the U.S.
To prevent spurious trips while ensuring plant safety whenever plant daily revenue is greater than $1 MM/day use an 'AND trip' (primary vent high pressure or flow along with indication of secondary seal
Dresser-Rand and Ener-Core have made progress in their collaboration by scaling up to a 2 MW
version of the Dresser-Rand's KG2-3G gas turbine that uses Ener-Core’s gradual oxidizer to burn a range of low-grade waste gases.
The “Tragedy of the Commons” is an economic theory first authored by Garrett Hardin. It states that individuals acting independently and rationally according to their own self-interest, behave contrary to the best interests of the group as a whole, by depleting some common resource.
Compressor operating pressures and flare header pressures can and will vary from the values specified on the seal data sheets.
Using one of the following methods will ensure that a seal face pressure reversal, which can fail the seal, will not occur:
Wind is good, anytime…anywhere! I like how they look and I like what they do.
But, have you ever noticed that all the success claims relate to how much wind capacity has been installed, rather than how much power that has been generated.
To illustrate, here’s some recent data on installed capacity:
