Your Complete Refinery Turnaround Service Provider


Envent Corporation: Your Complete Refinery Turnaround Service Provider

Houston, Texas – Envent Corporation, a recognized leader in environmental and industrial solutions, stands as the trusted name for complete refinery turnaround services. Refinery shutdowns and turnarounds are critical windows of time where every minute counts, and Envent is the go-to company for comprehensive solutions, from vapor control to water treatment.

Optimizing Turnaround Efficiency

Refinery shutdowns and turnarounds are high-stakes operations where time truly equals money. Any unplanned hitches can disrupt schedules, put plants out of compliance with regulations, and result in substantial financial losses. At Envent, we understand the importance of regulatory compliance, exposure reduction, and safety on behalf of our clients. We are committed to helping our clients make the most of their planned turnarounds and, more importantly, addressing unforeseen issues.

Customized and Engineered Solutions

Envent’s refinery turnaround services offer tailored and engineered solutions designed to meet the unique needs of each client. Our offerings encompass flareless options and support for Flare Gas Recovery Units (FGRUs) during Maintenance, Startup, and Shutdown (MSS) events. We specialize in the complete destruction of a wide variety of vapors, including steam, nitrogen, hydrogen, H2S, as well as high and low BTU vapor streams. Additionally, Envent is equipped to treat the water generated in preparing your unit for maintenance.

Time Efficiency is Key

The Refinery Shutdown Relief (RSR) regulations can limit the use of a refinery’s flare during a turnaround, causing extended depressurization and decontamination time. Envent boasts the largest fleet of thermal oxidizers in the United States, including the largest mobile thermal oxidizer available – the EMECS 77, capable of handling 34,000 SCFM and 77 MMBTU/hr. This remarkable capacity enables Envent to significantly reduce the time required for unit depressurization, all while ensuring 100% compliance with environmental regulations.

Collaborative Approach

Envent’s experienced engineers work in close collaboration with your turnaround planning team and environmental department, often months in advance, to provide customized solutions for vapor control and water treatment. Our engineers played a pivotal role in the design and construction of our equipment, ensuring that it is tailored to your facility’s unique needs. Our comprehensive consultation includes the provision of expert operators and equipment, ranging from tanks and piping to pumps, scrubbers, water treatment systems, and proprietary chemicals. We also offer sophisticated compliance monitoring and reporting, led by our expert operators and engineers.
