From: Dwight Mallory <Dmallory@resoluteenergy.com> Sent: Monday, June 15, 2015 3:26 PM To: Kelly, Shaheerah Subject: MCU Draft Permit BACT Discussion - Air Assist Blower Information Attachments: MCU Plant flare blower infor.pdf; Flare Pressure Blower Bulletin 451.pdf; SC-521- S1R2.pdf


## Shaheerah, Attached is the information we discussed on the MCU Main Flare air

‐ assist blower and flare tip. The blower is currently driven by a 2

‐ speed electric motor operating at 1,800 or 3,600 rpm, which produces a perimeter assist air flow volume of 2,060 scfm and 4,118 scfm respectively. In short, we think that the requirement to install a variable speed drive on the blower is arbitrary, and that compliance with the NHV dilution parameter specified in the draft permit can be achieved with the existing blower arrangement by properly staging the 2 speed blower based on the vent gas flow rate. The blower does not run when the flare is in purge gas only mode.

# A LUMINUM The unique Aluminum Pressure Blowerwheel is designed to provide efficient performance and reduced sound levels . . . the dual-taper design concept on all but the narrowest wheel sizes yields typical efficiencies up to 10 percentage points greater than conventional straight radial wheels. Riveted high-strength aluminum alloy blades and side plates minimizeoverhung wheel weight and starting inertia. Ductile-iron, taper-lock hubs make wheels easily removable. 

# O PTIONAL 

# S TEEL Either welded steel or stainless-steel wheel construction is available in straight radial design. AMCA Certified Ratings Seal applies to Pressure Blowers with aluminum-wheeldesign only. Air volume and pressure capabilities are the same as the dual-taper aluminum wheel, but brake horsepower requirements are typically higher. Refer toThe New York Blower Company’s fan-selection program for details. Note: Some fan-and-motor combinations with steel wheels may be restricted due to starting torque requirements. Consult nyb

### SAFETY EQUIPMENT Safety accessories are available from nyb , but selection of the appropriate devices is theresponsibility of the systemdesigner who is familiar with the particular installation, or application, and can provide for guards for all exposed moving parts as well as protection from access to high-velocity airstreams. Neither nyb nor its sales representatives is in aposition to make such a determination. Users and/or installers should read “Recommended Safety Practices for Air Moving Devices” as published by the Air Movement and Control Association International, Arlington Heights, Illinois.

# C ORRECTION 

# F ACTORS Performance is based on actual cubic feet per minute [ACFM] at the blower inlet at standard density [.075 lbs./ft. 3 

### ] and static pressure at the blower outlet. Static pressure capabilities are shown in inches water gauge [ ” WG]. Air density corrections are necessary for proper selection when air density varies from the standard .075 lbs./ft. 3 

### at 70 ̊F. at sea level. This also occurs when negative static pressure exists [rarefication] on the inlet side of the fan. Multiply the required static pressure at conditions by the appropriate factors in Charts III, IV, and V to obtain corrected pressure for blower selection. Pressure and BHP will be reduced at conditions by the inverse of these factors. Multiply one factor by the other if temperature, altitude, and rarefication are non-standard. For example: If the installation is located at an altitude of 4000 feet, the gas temperature is 300°F., and the inlet pressure is –40 ” WG, the correction factor is 1.84 [1.16 x 1.43 x 1.11].

A Size 2106A will provide 800 CFM at 33.6 ” SP. Determine the BHP required for the point of operation . . . see page 4 for steel or stainless-steel wheel factors. 2106A requires 6.3 BHP. 2106S requires 7.2 BHP [6.3 x 1.15]. Read to the right to select motor horsepower. A 7 1
