The invention relates to a method for recycling metal pickling baths, including rinsing baths and air washers.
The coolant, at 90°C, can bring the cleaning baths up to temperature via the heat exchangers.
The spent adsorption material that has been used in the adsorption process is thereafter used as neutralisation agent for the neutralisation of waste acids, such as spent pickling baths .
Since 2001, the Indaver ARP (Acid Recycling Plant) has been recovering hydrochloric acid from three pickling baths at Tata Steel, Ijmuiden, in the Netherlands.
The pickling baths, pasta, spray picklings and electrolytes produced by GSM are constantly refined and tested, with regard to health and environmental aspects.
And we wanted to use the waste air from the compressors to heat our component cleaning baths," explainsSiegfried Schmid, Managing Director at ZBG Motorentechnik.
The Chemirec® process has been conceived as a highly innovative solution for the recovery of hydrochloric acid (HCl) from the effluents of exhausted metal pickling baths.
Life Dime has been conceived as a highly innovative solution for the recovery of hydrochloric acid (HCl) from the effluents of exhausted metal pickling baths.
The invention relates to a method for recycling metal pickling baths, including rinsing baths and air washers.
The removal of a coating from components after they have been used is often achieved using various acid baths and salt melts.
Disclosed is a dry etching method which enables to reduce etching products in the etching process and improve in-plane uniformity with respect to the etching object.
Disclosed is a resist stripping agent which has excellent stripping properties, which has no flammability and therefore is safe, and which does not cause corrosion of a conductive material and therefore has excellent anti-corrosion properties.
A fresh stripper liquid is suitably added to the stripper liquid from which the resist components have been removed, and the resultant stripper liquid is reused in the stripping step.
The etching rate ratio between palladium and gold (etching rate of palladium/etching rate of gold) is not less than 1.
The present method is a method of electrochemical stripping analysis comprising an electrolysis step and a stripping step.
