Abstract: The paper analyzes the scheme for capacity expansion and technical transformation of the plant which has a limited reconstruction space and presents difficulties to undergo capacity expansion of its heavy medium and slurry water treatment systems. Analysis shows that the use of the 3-product smart TDS separator can well tackle the above-mentioned problems and enable the H. M. vessel to operate with a reduced load and wash down to a smaller size. Other attractions brought about by the renovation work include higher separating sharpness, curtail of operating cost, ability to produce diversified products and improvement of economic performance.
