Challenge A customer of ours has two cargo ships that constantly transfer cargo up and down the west coast. These ships are always sailing back or forth with commerce and are on extremely tight schedules. Envent Corporation was challenged with assisting in the commissioning a new LNG fuel system on one of these cargo ships, […]
Challenge In response to the COVID-19 pandemic, the Biomedical Advanced Research and Development Authority (BARDA) and its Contract Development and Manufacturing Organization (CDMO) network were rapidly established to scale vaccine production. One of Envent’s customers was approved to join the network to manufacture COVID-19 vaccines and needed to begin production quickly. The client required an […]
Challenge A customer in the Midwest needed to reduce noise coming from a natural gas pipeline blowdown. Pipeline blowdown operations can be very loud have the potential to disrupt the immediate area. The gaseous contents of the pipeline are at high pressure and when that pressure is under controlled release, creates an unpleasant rushing sound. ENVENT was called upon to assist […]
Emergency Response. To control refinery vapor stream containing 10,000 ppmv of H2S in a VOC stream from a vessel pressured to 300 PSIG. The project was completed in 24 hours hours without incident.
Challenge A major Houston refinery engaged Envent Corporation in a competitive bidding process alongside several thermal oxidizer companies to support the cleaning and degassing of an underground API separator. This rectangular tank with an external-floating roof had accumulated years of wastewater hydrocarbons from multiple refinery operations—resulting in a potentially hazardous, unidentified mix of vapors and […]
Envent provided equipment over a three-year span ranging from small carbon vessels all the way up to our 42 MMBTU/H EMECS42 Thermal Oxidizer along with three other Smaller thermal oxidizers.
Challenge During a turnaround for an Olefins Unit, a customer tasked Envent with providing a vapor control system to process stray hydrocarbon vapors while their normal vapor recovery system was down for maintenance. The customer’s unit superheaters were to be shut down for three months, and without a proper solution in place, the customer would […]
Challenge Due to the recent pandemic striking the world, a gulf coast refinery adjusted their refining process to allow them to continue production. They found a surplus of C4’s (n-butane, isobutane, etc) that typically sell with ease. During this process, multiple variations of C4’s are made from a single process. 1-3 Butadiene demand remained high, and […]
Challenge A West Coast pipeline company contacted Envent Corporation to provide vapor control services during a high-pressure pipeline purging operation. Traditionally, large carbon adsorption vessels are proposed for this type of project. However, due to the elevated operating pressure, using standard atmospheric vessels would have required costly high-pressure-rated alternatives or protective systems to prevent failure […]
Challenge A Gulf Coast refinery encountered an emergency shutdown on one of its reactors due to spent catalyst, requiring immediate replacement. The replacement had to be completed quickly to avoid delaying the startup of the refinery’s alkylation unit. The cleaning and neutralization process required three distinct phases and involved a complex atmosphere of: Pressures exceeding […]
Challenge We have a long term project located in Southern California where we are providing vapor control for tanker trucks being loaded with crude. We decided to use a TO as the carbon spend rate will be very high. The unit is always on hot standby. The challenge of this project comes from the inconsistency […]
Challenge A mid-west facility was under a time and regulatory constraint to reduce H2S emissions coming from a cold feed storage tank. There were many requirements that had to be met to sufficiently perform this job including having a high flow at the system. Envent had to figure out a way to knock out aerosol and oily […]
