Problems solved by technology

The problem with silica is that when this water is used to generate steam, such as in boilers, the concentration of silica must be controlled
[0010] In practice, operations as described above for deoiling often fail to handle process upsets

Abstract

A process for treating produced water in heavy oil production comprises, providing an oil / water mixture gathered from an oil / water collection well, whereby oil from said oil / water mixture is separated to provide an oil product and a produced water product containing oil, dissolved gases and dissolved solutes. Said produced water product is then deoiled, and the deoiled water subsequently passes though a membrane system, resulting in permeate water and reject. The resulting permeate water is sent on to a boiler system for production of steam, and the reject is introduced into an evaporator to result in distillate water and blow down. Thereafter, the blow down may be charged into zero liquid discharge treatment; and the distillate water added to the membrane permeate.

Description

field of invention [0001] The present invention relates to a method of preconcentrating produced water, particularly water produced during bitumen recovery in tar or oil sands. Background of the invention [0002] In some geological formations, such as those known as oil sands or tar sands, steam is used to recover heavy oil in these formations. Steam is injected into heavy oil-bearing formations to heat the heavy oil or bitumen, making it more viscous and allowing the oil and water mixture to collect and be pumped to the surface. The steam that condenses into water and mixes with the oil, and is subsequently separated from the oil is called produced water. In new wells, the ratio of water to oil is about 3:1. As the well ages, the water to oil ratio changes and can be as high as 7:1. In some cases, the oil is separated from the produced water, which is recycled for reuse in generating steam for reinjection into the well formation. [0003] Processing produced water to t...
