Evaporators

Proven Global Experience

GE Water & Process Technologies (GE) is the pioneer and industry leader in produced water evaporation and crystallization systems, having developed its patented high pH evaporation technology in the late 1990s and optimized its evaporation and crystallization technologies over the past 10 years.

Improving on a Proven Technology

With a best-in-class research and development program and abundant experience from several commercially operating produced water evaporator systems, GE continues to optimize and improve upon its high pH evaporation technology.

Some recent optimizations include:
More than 50% reduction in caustic consumption, resulting in the lowest chemical and operating costs of any produced water evaporative technology
Elimination of scale inhibitor, further reducing chemical costs and producing evaporator blowdown that is easily post treated prior to deep well injection
Cascade and split-sump evaporator designs providing lower capital costs and improving energy efficiency
An internal Contaminant Reduction System for superior distillate quality and reliable operation of high-pressure (>1,000 psig) drum boilers
In situ chemical cleaning to improve system availability and maximize steam to field

Modularization Reduces Cost
Understanding that cost and schedule certainty are of the utmost importance for heavy oil producers, GE offers completely modularized evaporator and crystallizer systems.

First modularized evaporator system in 2002
Total of 11 modularized evaporators / crystallizers
Currently on 4th generation module design
Experienced team of engineers, drafters, quality control, and field engineers
Cooperative efforts with engineer and constructor
Partnerships with local fabricators, module yards and Alberta structural engineers

Produced Water Evaporator Blowdown Solutions

There are two common methods to treat or dispose of produced water evaporator blowdown:

Deep well injection-The recent optimizations to the high pH produced water evaporation process result in a safe and straightforward post-treatment process prior to disposal.
Zero Liquid Discharge-Crystallization of high pH evaporator blowdown results in waste slurry of mixed salts, silica, and organics. This waste slurry is unique to produced water applications. GE has five crystallizers operating or under construction in the Alberta Oil Sands and is highly experienced in handling this unique waste stream. A drying or solidification/stabilization process treats the waste slurry for final disposal in a landfill.
     a. Drying -A proven method of waste slurry treatment that results in a dry, free-flowing solid residual for disposal in a lined landfill.
     b. Solidification -An alternate to drying, solidification is a simple and environmentally friendly way to treat crystallizer waste as it produces a stable solid for disposal in standard landfills, eliminating long-term liability associated with other disposal methods.
