Steel Tank and Process Vent Applications

Stringent environmental emission regulations mandate that industrial facilities curtail the release of volatile organic compounds (VOC) with vapor emission control systems. Vapor phase activated carbon adsorbers are ideal for eliminating or minimizing the emission of VOCs from atmospheric tanks or process vents.

Potential tank vent emission sources include:

  • Tank emissions due to diurnal temperature changes
  • Displacement during tank filling product transfer operations
  • Continuous process vents
  • Interruptions in operation of existing control system due to maintenance requirements or system failure
  • Railcar, tank truck and barge loading
  • Tank cleaning
Tank and Process Vent Applications

From complex vapor emission control systems to one-vessel solutions, TIGG has vapor phase adsorption units that remove VOCs from industrial processes.

Since every facility is different, no single solution is a fit for every factory. TIGG’s experienced engineers can design vapor phase activated carbon adsorption systems to remove contaminants from vapors exiting atmospheric tanks during filling operations and diurnal temperature changes.

Not only do these vapor phase adsorbers curb VOCs, facilities that use thermal oxidizers as their primary VOC containment solution can realize cost savings by adding activated carbon adsorbers to capture emissions during non-peak emission times. The cost of using natural gas to incinerate VOCs can be expensive. Vapor Phase adsorbers are cheaper to maintain and electric blower systems are the only component in the process that requires power.

TIGG has a wide array of vapor phase activated carbon adsorption options available, ranging from 55-gallon drums up to integrated adsorption systems capable of handling flow rates up to 20,000 CFM. Our integrated vapor emission control systems can include intricate pipe rack set ups as well as blowers and electronic control panels.

We have a large in-stock inventory of vapor phase adsorption systems for industrial vapor emission control for sale or ready to rent. If you require customization call a representative at 800-925-0011 or complete a RFQ.

TIGG- Activated Carbon Tank & Process Vents

Thermal Oxidizer Backup

A major chemical plant wanted a backup for a thermal oxidizer treating gases vented from a tank containing a light hydrocarbon product.

TIGG provided two ASME Code vessels containing 2000 pounds of carbon that will treat 167 ACFM of tank emissions during tank filling when the oxidizer is offline.


Temporary Replacement of Regenerative Thermal Oxidizer (RTO)

A Northeast chemical company was experiencing operating difficulties with their RTO and had to shut it down for four to six weeks to make repairs. To keep the chemical plant running during the repair period, the air permit requirements on the 11,000 CFM contaminant stream still had to be met. A temporary solution was needed.

The next day, two TIGG NB 20s, each loaded with 20,000 lbs of activated carbon, flexible duct and an air handling system, were on the road and delivered to the site. On-site carbon exchange and disposal services were also performed due the high concentration of organic compounds in the air stream. The temporary system worked as predicted and kept the chemical plant running around the clock until the RTO was back online.


Adsorbing Vapors from Crude Oil Tanks
 
A Gulf Coast Refinery needed to control emissions from a process tank. The tank vents intermittently due to fluctuations in tank levels and/or process conditions and contains traces of hydrocarbons, hydrogen sulfide and condensing water vapor. TIGG provided a control system consisting of a knock out drum for condensate removal, an adsorber containing impregnated activated carbon to capture the H2S, an adsorber containing 5200 pounds of vapor phase activated carbon for primary removal of light organics, and a final NB20 carbon adsorber containing 20,000 pounds of vapor phase activated carbon as a final treatment and "fail safe precaution."


Caustic Tank Emissions

A hydrocarbon processing plant required a system to remove VOCs from a spent caustic treatment tank. Due to level changes, vapors containing hydrocarbons are released from a layer of organics that form in the tank. TIGG provided an adsorber vessel with a stainless steel distributor containing 2,000 pounds of activated carbon to control emissions.


Emission Control During Terminal Transfer Operations

A refinery required immediate, temporary control of hydrocarbons vented during high volume product transfers between transport tankers and the terminal's storage tanks. In less than 24 hours, an NB20 containing 20,000 pounds of activated carbon was delivered, installed and placed into operation. As a result, the client avoided permit violations and was able to complete the product transfer.
