    • A system and process for processing a predominantly aqueous phase solution separated from an emulsion coolant recovered from can bodies in a can manufacturing process to recover reclaimable oil. A recirculation line is provided between an ultrafiltration device and a processing tank which receives a predominantly aqueous phase solution produced by acid cracking processing of the emulsion coolant. A substantially constant waste concentration level is maintained in the processing tank and, consequently, through an ultrafiltration device by bleeding concentrated retente from the recirculation line. The substantially constant waste concentration level extends the cleaning cycle period of the ultrafiltration device by an amount consistent with the ability to process concentrated retente bled from the recirculation line. The ultrafiltration device produces a permeate effluent which is consistent and suitable for discharge.
    • 一种用于处理主要水相溶液的系统和方法,所述水相溶液与罐制造过程中从罐体回收的乳液冷却剂分离,以回收可回收的油。 在超滤装置和处理罐之间提供再循环管线,处理罐接收通过乳液冷却剂的酸裂解处理产生的主要水相溶液。 在处理罐中保持基本上恒定的废物浓度水平,并且因此通过从再循环管线中渗出浓缩滞留物通过超滤装置。 基本上恒定的废物浓度水平将超滤装置的清洁循环周期延长与从再循环管线排出的浓缩滞留物的能力相一致的量。 超滤装置产生一致且适于排放的渗透物流出物。

    • Used oil and water emulsion coolant recovered from can bodies in a can manufacturing process is processed to form reconstituted emulsion coolant by washing emulsion coolant adhering to can bodies off of the cans with an aqueous solution having a pH less than about 2.0 thereby forming a mixture of the emulsion coolant and the aqueous solution, heating the mixture to an elevated temperature sufficient to break a substantial portion of the emulsion coolant into a predominately hydrocarbon phase and a predominately aqueous phase, separating the predominately hydrocarbon phase from the predominately aqueous phase, adding a sufficient amount of water to the predominately hydrocarbon phase to reconstitute the emulsion coolant, adding a sufficient amount of an emulsifying agent or agents to the predominately hydrocarbon phase and the water to emulsify the predominately hydrocarbon phase and the water, and filtering the predominately hydrocarbon phase, the water and the emulsifying agent to form reconstituted emulsion coolant.
