Cool system for hot tyres AERZEN Hungaria supplies packaged units for butadiene treatment plant A leading company in the Central European petrochemical industry relied on AERZEN’s products and professional competence in the construction of a new butadiene treatment plant. The system consists of three compressor packages VMY 156, one air-cooled condenser, three evaporators and one propylene vessel. Cooler system made by AERZENCompressor packages supplied by AERZEN Hungaria are making an im- portant contribution to automotive mobility: one of the biggest plastics manufacturers in Europe is using the packages in its new butadiene treatment plant, generating the raw material for synthetic rubber, and thus the source material for tyre production. At the location Tiszaújváros (Hungary), the plant has, since spring 2015, been producing 1.3 butadiene for the Hungarian factories of many internationally known tyre manufacturers. The cooler system at the plant was supplied by AERZEN. This consists of three VMY 156 compressor packages, one air-cooled condenser, three evaporators and one propylene vessel. Always 150 per cent refrigerating capacity In operation case 1, 545 kW of refrigerating capacity, and thus the application of two VMY 156s, is necessary. In operation case 2, however, 320 kW of refrigerating capacity, and thus only one VMY 156, is necessary. Thus, the system always supplies 150 per cent refrigerating capacity and one packaged unit is always available as stand-by. This is important, because butadiene must be cooled continuously, as otherwise it will polymerise and stick to the surfaces of pipings and tanks. For this reason, the system has three evaporators. The first evaporator cools the butadiene, when it comes from the plant and is led to the two spherical tanks with a size of 2,500 m3. The other two evaporators provide additional cooling. Besides the production of the cooling system, the team from AERZEN Hungaria was also responsible for its installation at the customer’s plant.
