Evergreen Industrial Services is a technically focused company continually seeking solutions that reduce downtime and improve owner/operator performance and reliability. Evergreen maintains a highly skilled project management team incorporating best-available technologies with specialized high-performance equipment. As a partner, Evergreen measures value in the ability to understand the critical path components involving maintenance, environmental compliance and operational objectives. Nowhere is this more evident than in the arena of chemical cleaning.
Over the past few years, the impact of maintenance, start-up and shutdown compliance and environmental awareness has rendered previously proven processes and procedures obsolete and environmentally noncompliant. This leaves a number of owners/operators in situations to redesign shut-down and start-up procedures with limited knowledge, expertise or no bench strength to bridge the gap between previous best practices and evolution to the newest available technology. These systems are currently at risk to overload during high-demand situations, causing critical pinch points in the ready-for-maintenance process as well as significant risk to an environmental event.
Chemical cleaning has been active in the ready-for-maintenance procedures for years, delivering time savings in steam-out and de-inventory processes, as well as providing a high level of vessel cleaning and decontamination. However, chemical cleaning must evolve with the needs of Evergreen’s customers and the answer is not necessarily more chemistry and longer cleaning durations. To achieve a successful chemical cleaning, the method of applying the chemistry is as important as the chemistry itself.
Evergreen has developed a cleaning team focused on the integration of chemical cleaning applications into the critical activities beginning with the de-pressuring and the de-inventory processes. The Evergreen team has more than 150 years’ experience of critical path chemical cleaning applications supported by extensive chemical and refining process knowledge.
Evergreen continues to redesign its cleaning equipment to match process temperatures and pressures. This specialized ancillary cleaning equipment is incorporated into process units eliminating pinch points and providing options to pumping recovered product to storage versus waste. Evergreen has designed and regularly utilizes a combination of heat exchangers, knock vessels and even thermal oxidizers removing more than 90 percent of the demand on existing undersized flare gas recovery systems.
No matter the project size, or complexity, the development and planning process is the same. Evergreen evaluates process flows, operational history, scale and deposit sampling; develops blind/isolation lists, instrumentation isolation and protection plans; provides isometric drawings for temporary piping and spools, process safety reviews and detailed step-by-step procedures; agrees on acceptable testing and process monitoring; and concludes with waste storage and conservation plans. It is this level of project design and contingency planning that establishes a partner-ship between owner and contractor that delivers the predictable and reliable results each and every time.
