Additional Combinations

BORSIG Process Heat Exchanger GmbH supplies HT shift waste heat boilers which are arranged behind HT shift reactors to recover heat from process gas.

The HT shift waste heat boiler is fitted with seamless straight tubes. Due to low gas temperatures thick tube sheets are provided.

The tube ends are hydraulically expanded. The tube bundle is provided with support plates and tie rods.

BORSIG Process Heat Exchanger GmbH supplies steam drums for high steam pressures up to 16,500 kPa and steam flow rates up to 500 tons/hr. Steam drums are provided with demisters for steam purification. Cyclones can be provided. All drums are furnished with separation chambers for defined internal flows, with vortex breakers, thermos sleeve nozzle for BFW inlet, BFW distribution pipe system, chemical dosing device, continuous blow down pipe, instrumentation nozzles and oval manholes with self-tightening pressure sealing covers. We can deliver the steam drum with complete instrumentation.

BORSIG Process Heat Exchanger GmbH supplies feed water preheaters for a wide range of applications in the petrochemical industry.

The feed water preheater can be equipped with straight tubes as well as with U-tubes. The boiler itself has thick tube sheets due to the low gas inlet and gas outlet temperatures. The tube ends are hydraulically expanded over the tube sheet thickness. The tube bundle is provided with tie rods and baffle plates.

BORSIG Process Heat Exchanger GmbH supplies steam attemperators for controlling the superheated steam temperature. Steam attemperators can be integrated into the steam drums or designed as separate unit connected to the steam drum by down comer and riser piping and function on the principle of natural circulation like a single waste heat recovery boiler. Steam temperature can be controlled by an internal bypass valve.

BORSIG Process Heat Exchanger GmbH supplies gas/gas heat exchangers for petrochemical plants. The gas/gas heat exchanger is fitted with seamless straight tubes. The tube bundle is provided with baffle plates and tie rods. To compensate the high temperature difference between tube and shell the exchanger is provided with floating head to compensate resulting compression and expansion stresses.
