Demolition
We have been involved in the Demolition of numerous Petroleum Facilities in Western Canada. Petrocare Construction is there for all aspects of the work required, whether that include de-identifying, remediation, demolition and transportation and disposal we will care for it all!
Of course we have extensive experience in fuel tank destruction and removal and disposal working closely with Environmental consultants and Agencies and if required we can offer consulting service of any kind.
Decommissioning
Decommissioning has been integral to Petrocare Constructions success for decades. Our experienced team has a record of safety, knowhow and efficiency second-to-none in the industry. From decommissioning small-town gas bars to very large plants including roadways, railways, large tanks, small tanks and buildings including all underground facilities we truly do it all.
Remediation
Petrocare can organize and supervise the cleanup of your site including performing hydrogeological investigations, installing monitoring wells, bioremediation, air sparging, groundwater treating, etc.
An environmental assessment is, more than anything else, an assessment of the chemical condition of a property. The core subject in defining environmental contamination is chemistry and an in-depth understanding of chemical principles is essential in the assessment of the chemical condition of any property.
Through our affiliated companies Petrocare Construction has what it takes to remediate any site for demolition, decommission or construction. Soils can be analyzed quickly which can avoid lengthy delays for excavators, trucks and others involved in the site cleanup. Indeed, costly extended studies can be avoided simply by monitoring a cleanup as it proceeds.
Petrocare Construction will perform a wide range of consulting services including Environmental Assessments of Industrial, Commercial, Residential Real Estate, and Gas Stations Field Sampling and Monitoring of Sewage Lagoons, Landfills Spill Delineation & Monitoring All environmental site assessments are carried out in accordance with Saskatchewan Environmental and Resources Management (SERM) guidelines. Our Contractor Certification No. is S 0310. Environmental audits are performed in accordance with the "Generally Accepted Standards for Environmental Investigations" published by the Consulting Engineers of Ontario (1993).
The Following is presented simply as resource material related to the remediation process.
Remediation Process
Free Product Removal
Our innovative technology is more efficient than traditional methods for removing free product. Placing a vacuum on the well counteracts capillary forces allowing for flow of the free product into the extraction well during the SVE process. Second, the extracted vapors are consumed by the normal combustion process of the engine, therefore no need for costly storage or disposal. And last, depending on the BTU value of the contaminants, the use of alternate fuel source is significantly reduced.
Bio-Slurping - Dual Phase Extraction (DPE)
The introduction of the DPE module to the Soil Venting Equipment (SVE) system allows us to perform dual-phase extraction, removing the petroleum hydrocarbons pooled above the groundwater, and hydrocarbon vapors and contaminated water at the water table, which considerably reduces total project costs.
Bio-Venting/Air Injection
vRSI's system is also used for Bio-Venting, which involves the flow of fresh air through the vadose zone to increase oxygen content and accelerate bioremediation. In Air Injection mode, heated air from the blowers, or compressors, can be routed via reinjection wells.
Soil Vapor Extraction The RSI Way
RSI's patented systems use the vacuum from the engine's intake manifold to extract the soil vapors.
Air flow rate is governed by the cubic inch displacement of the engine, rpm, system load, and site specific conditions. For large sites with multiple wells, positive displacement blower(s) driven by the ICE can provide extraction flow rates up to 2,300 SCFM.
Blower capacity in terms of total flow and vacuum pressure can be sized to meet each specific remediation design. For sites requiring higher vacuum (greater than 18" Hg), liquid ring vacuum pumps can be driven by the ICE. The ability to deliver up to 156 brake horse power with the eight cylinder engine allows us to meet every customer need.
Soil Venting, Bioventing, Dual Phase Extraction & Air Injection
Soil venting is an innovative technology for removing organic contaminants to remediate polluted soil zones. The organic contaminants can be in the soil in three different zones: as free "product" in pools or residual globules, dissolved in the groundwater, or as vapors in the vadose zone. Soil venting directly deals with the free product and the organic vapors in the vadose zone by applying a vacuum through wells and extracting the air in the contaminated zone. Soil venting also deals indirectly with groundwater contamination, by removing the overlying free product and vapors, promoting transfer of the contaminants into the vadose zone, where they are removed through the extraction wells.
