In this flow diagram, a process known as high density sludge (HDS) is employed to help promote precipitation. The heart of the HDS process is the pH in the HDS or densification tank which needs to be at a pH of 11.5 or higher. A change of state takes place at the higher pH and the process works better.

Mar 26, 2013· Pickling is the process of preserving foods in brine or vinegar or a combination of the two. Brine is made by combining salt with water in proportions to make either a weak, medium or strong solution. In some instances, salt is added directly to the food in the dry form and the brine is formed as juices are drawn out of the food.
Pickling is the process used to remove weld heat tinted layers from the surface of stainless steel fabrications, where the steel's surface chromium level has been reduced. PICKLING AND PASSIVATING STAINLESS STEEL 2. Comparison of Descaling, Pickling, Passivation and Cleaning

Integrated Data Reconciliation with Generic Model Control for the Steel Pickling Process 987 Korean J. Chem. Eng.(Vol. 20, No. 6) (10) (11) (12) Here, it was assumed that all process variables are measurable without noise except process flow rates with measurement noise of ±1% of true values. Therefore, steady state data reconciliation is
1. Total process water usage in the steel industry is about 5,740,000,000 (5740 MGD) gallons per day. The untreated process wastewaters contain about 43,600 tons/year of toxic organic pollutants, 121,900 tons/year of toxic inorganic pollutants, and 14,500,000 tons/year of …
Sep 20, 2013· PHAR process. Pickliq hydrochloric acid regeneration (PHAR) is a process for regeneration of spent hydrochloric acid from steel pickling. The process is applicable to any size pickling operation. In this process SPL typically exits from the pickling line at around 11 % to 13 % iron and 2 % to 4 % free hydrochloric acid.

A dynamic model of the continuous titanium pickling process, as shown in Figure 1, for the change in volume and temperature will be developed for all of the prerinsing, pickling, and rinsing steps based on the following assumptions: (1) There is perfect mixing; thus, the exit temperature is also the temperature of the bath contents. And the heat of mixing is negligible compared to the heat of ...
Jan 01, 2006· The steel strip passes also without stopping through the pickling process, where the coils are welded tail to head at the process entry point. The pickling section consists of four pickling tanks and there is a cascade flow of pickling solution counter-current to the direction of strip movement.
