Challenge A customer facility had two large runoff tanks filled with several million gallons of high pH water associated with groundwater remediation. The customer wanted to drain both vessels to make room for additional wastewater, but each tank’s contents would need to be treated to a neutral pH prior to discharge. Additionally, sulfur precipitates in […]
Challenge The challenge of this project is to provide supplemental soil vapor extraction (SVE) and vapor control to the plants existing vapor recovery system. Additional soil vapor extraction wells were installed on the periphery of the plant due to the expansion of the landfill. The plants SVE blowers are unable to provide sufficient vacuum and […]
Challenge An underground gasoline pipeline had a leak that went undetected for an unknown duration that caused leaching into the ground. As a result of the volume of contaminated soil, strong gasoline odors were detected in the area. Those nuisance odors were affecting nearby neighborhoods causing community concern and complaints. Solution Envent scoped out the […]
Challenge A refinery sulfur recovery loading rack was giving off foul/hazardous odors to truck drivers and personnel located in immediate surrounding area of sulfur recovery unit (SRU) during truck loading events. Truck drivers inside the refinery were required to dawn SCBA’s and load trucks with truck dome hatches open. They had to visually […]
Challenge A chemical manufacturing facility in the Southeastern US had a large underground cleanup of toxic chemicals that had been spreading underground for many years. They had a design for the tent enclosure that the heavy equipment would be working in but needed a vapor recovery system to make sure none of the hazardous vapors […]
Challenge A customer tasked Envent to help evacuate an Ammonia tank skid and the surrounding piping so that multiple valves in the system could be replaced safely. Envent would have to provide a solution to handle liquid ammonia, associated temperature issues, and chemical hazards. Solution Envent provided the customer with a High Pressure Regulator, a […]
A large North East Oil and Gas customer needed to perform much-needed maintenance of degassing and tank cleaning on one of their Crude Oil tanks. High odor concern, public safety, scrutinized media attention required a solution by Envent Corporation that was fast, odor free, safe to neighbors, and in compliance with local regulations.
Envent developed a three phase vapor odor control solution for a Pacific Northwest customer utilizing a recirculating scrubber (for H2S removal) and a high flow thermal oxidizer to safely eliminate nuisance odors to the surrounding community as well as maintain 100% compliance and zero fines.
An 80,000 bbl. /day crude distillation unit underwent a month long planned shutdown in order to perform maintenance on their exchangers, and pressure vessels.
A Midwest refinery contracted Envent to provide degassing and vapor control services. The refinery planned a major turnaround and had multiple critical-path process units that needed industrial degassing and industrial vapor control services for safe entry into process vessels.
Challenge A refinery in Southern California experienced severe plugging in a section of piping downstream of their coker unit. In order to eliminate the restriction, the refinery needed to perform a line break and attempt to clear the line. The column attached to the line contained high concentrations (2500 ppm) of ammonia vapors and the […]
