Redesign of Washing Process of Cartridge Case Using a Combination of Acids, Detergents and Anti-Tarnish Compounds	2017	6	.pdf	application/pdf	3389	133	48	Methodologies like Retrofit Design Approach and Hierarchical Decision Procedure by Douglas were combined for: 1) determining input Information, 2) developing diagnosis and identifying improvement proposals, 3) establishing input – output structure of the flowsheet, 4) defining critical variables of the process (CVsP), and 5) designing new units that support the change from batch process to continuous process. % liquid ρ kg/m3 χ % Production volume by shift (7.5h) Time of loading cartdrige cases to washing tank in min Manual operate valve Process Time of cartdrige cases unloading from washing tank in min Water Time of mixtures loading in min On-Off Valve Steam Time of mixtures unloading in min Time of mixtures preparation in min Washing time min/batch Input streams: steam 1,3 Output streams: draining of mixtures 5 Barrel 1 Mix detergent and hot water Barrel 2 Mix degreaser and hot water Barrel 3 Mix acid solution 1 and water Barrel 4 Mix acid solution 2 and water Washing tank 1 Washing tank 5Washing tank 4Washing tank 3Washing tank 2 1 2 3 4 5 V1 V3 V2 V4 V9 V5 V10 V6 V11 V12 V7 V13 V8 V14 V18 V21V20V19V17 V16 V15 1503 During the evaluation of batch process variables using CPVs – Determination Matrix (see Figure 2), only seven process variables were selected for to be evaluated: materials pH (detergent, degreaser and acid solutions), temperature of water °C, foam density kg/m3, detergency efficiency %, liquid mixture density kg/m3 and concentration %.	cache/cet-2314.pdf	txt/cet-2314.txt
