Design a lubricant production system that can produce 1000 liters of lubricant per hour for use in heavy machinery. The system should be cost-effective, environmentally friendly, and able to meet industry standards for quality and performance. Include a detailed process flow diagram and a list of the necessary raw materials, equipment, and safety precautions for the production process. Additionally, calculate the total production cost per liter of lubricant and propose strategies for reducing production costs without compromising product quality.
