Solvent recovery in the pharmaceutical industry is not as simple as buying a device: there are many kinds of solvents, large fluctuations in batch working conditions, intertwined emission and reuse requirements, and the device can really run only if it matches the process. LuoyangWohong PetrochemicalEquipment Co., Ltd. provides the overall solution of solvent recovery for pharmaceutical enterprises, starting from exhaust point diagnosis, to process route adaptation, device supporting manufacturing, on-site installation and debugging, to operation training and long-term operation and maintenance support, and delivering complete sets according to the actual situation of the workshop.
The first step of the scheme is point diagnosis: combing the exhaust gas of crystallization, centrifugation, distillation, drying, vacuum pump and other links point by point, classifying according to concentration and gas volume, and determining which ones enter the recovery unit and which enter the purification unit. The second step is process adaptation: according to the solvent component selection of condensation, membrane separation and its coupling route, determine the condensation temperature, membrane module configuration and buffer design. The third step is equipment matching and delivery, including collection pipe network, recovery skid-mounted unit, control system and measurement sampling facilities, unified design and unified construction.
The first is batch adaptation: pharmaceutical production is intermittent, the amount of tail gas fluctuates greatly with the batch, buffer tank and automatic control adjustment are standard, and the condensing unit is selected according to the peak value. The second is component adaptation: ethanol, ethyl acetate, acetone, dichloromethane and other solvents are commonly used in the same workshop. The scheme is designed according to the main components and is compatible with batch changing conditions. The third is reuse adaptation: the inspection of the recovered solvent is connected with the reuse route and the workshop quality system, so that the recovered solvent can be really used back instead of being collected.

It is suggested to look at the effect from two dimensions: the environmental protection dimension looks at the improvement of discharge outlet concentration and workshop air quality; The economic dimension looks at the decrease of solvent unit consumption and the amount of recycled solvent. When the plan is delivered, the measurement and ledger are established simultaneously, and the operation data is issued every month, so that the return of governance investment is clearly visible.
The scheme is designed according to the main solvent, checked according to the range of components, and the buffer design absorbs batch fluctuations by adjusting the temperature level and load during batch change.
Sure. After evaluation, the old device can be retained or incorporated into the unified pipe network, and the scheme is designed in a combination of old and new to avoid duplication of investment.
The period from survey to commissioning depends on the scale of the plant and site conditions. The overall plan is given a clear schedule at the contract stage, and the construction is combined with the maintenance window arrangement.
