Petrochemicals
Catalytic processes with LEWA pumps
Petrochemicals generate starting products for the manufacture of plastics, pharmaceuticals, colorants, detergents, and other products. The most important operations are the various splitting or cracking processes (e.g. steam cracking, hydrocracking). These processes convert long-chained hydrocarbons (e.g., naphtha) into short-chained ones.
LEWA supports your production plants with effective additive metering, as well as with the conveying and treatment of washing water and sour water.
LEWA offers you specialized solutions for the metering and conveyance of the required chemicals and products. We design pumps and systems to suit your requirements and offer you all-round support for processes such as hydrocracking.
Areas of Application in the Petrochemical Industry
LEWA pumps and metering systems are used in the petrochemical industry for many processes in the hydrocracking and steam cracking sector.
| Product applications | Chemicals | Process/System |
|---|---|---|
| Metering chemicals in the petrochemical industry | Deposit inhibitors | Distillation plant, reformer system, cracker, coker |
| Tetrachloroethylene | Reformer system, cracker | |
| Defoamers | Distillation plant, reformer system, cracker, coker | |
| Emulsion breakers | Desalination plant, distillation plant | |
| Corrosion inhibitors | Distillation plant, reformer system, cracker | |
| Metal deactivators | Cracker | |
| Sulfiding agents | Reformer system, cracker | |
| Lubricity improvers | Reformer system | |
| Oxygen scavengers, oxygen binders | Cracker |
In addition to the hydrocracking and cracking process, we also support other typical refining processes with distillation plants.
