Case study - Petroleum remediation systems


Courtesy of Anguil Environmental Systems, Inc.


A major oil company was looking for a way to stay ahead of EPA regulations for soil vapor extraction of BTEX and the subsequent treatment of these gases. They were looking for one company that could offer competitive pricing, local support service, and the application expertise to provide 50 remediation units throughout the United States.


Global Technologies built a Model 7 Integrated Vapor Treatment Module (VTM) Remedi-CatTM. This modular system processes a maximum of 750 SCFM of VOC-laden air and provides 99% destruction efficiency. This unit was designed around the numerous needs of the petroleum company.

First, the customer needed the unit to be mobile. This led Global to design a unit that is, in fact, 3 integrated systems. The Model 7 Integrated Remedi-Cat is housed in a portable, box-like enclosure that is weather-tight and designed to be aesthetically pleasing. The unit contains an oxidizer, Vapor Liquid Separator (knockout-pot), and a vacuum extraction blower. The unit had to be adaptable to various vacuums and air flow conditions. Global met this by using a 20-hp Lamson Turbotron Regenerative Blower that is extremely flexible. It can achieve both high and low vacuums (2-8 inches Hg) at an air flow of 150-750 SCFM. The adjustable belt and sheave blower combination allows the vacuum blower to be resheaved to exact vacuum and air flow requirements.

Next, these units would be used at gasoline stations located in residential areas. Regulations in these areas are very stringent and some dictate that equipment cannot operate at more than 65 decibels, beyond a three foot perimeter. In order to meet this design requirement, Global installed dual-density sound deadening foam and sound louvers, which allowed air in, but prevented sound from getting out.

Additionally, Global, understanding that quick, reliable, cost-efficient service is paramount, did two things. First, a service office in Southern California was opened, where a majority of the initial units were located. Second, the unit was designed to simplify service and to maximize equipment up-time. Global built the Model 7 Integrated Remedi-CatTM with a Programmable Logic Controller (PLC). The PLC utilizes an operator message display feature which walks the user through start-up and, in the event of malfunction, supplies the user with a visual display indicating the problem. This feature reduced the need for on-site service calls. This design feature greatly increases the equipment up-time

In an attempt to expedite this project, Global Technologies obtained General Mechanical and General Electrical permits from Los Angeles County as well as a various location permit from the South Coast Air Quality Management District. This enabled the petroleum company to be proactive in responding to EPA regulations and allowed equipment to be placed on the site and begin operating immediately. This demonstrated Global's ability to work hand-in-hand with regulatory agencies.

Global Technologies' ability to understand a customer's unique needs coupled with the engineering know-how necessary to fulfill them, resulted in another satisfied Global customer.
