Vaporizers for Well Service
Product Code : VWP Series Vaporizer
Brand Name : Cryoquip India
Cryoquip has recently developed a range of vaporizers for the well service industry to provide large volumes of high pressure gas for use in oil, gas and geothermal well extraction enhancement, and also refinery cleaning, purging and other remotely located chemical purging applications.
The VDFC and AFDV series vaporizers, are truck mounted direct fired diesel liquid nitrogen converters capable of intermittent flow rates from 600,000 SCFH (17,000 Nm3/hr) to in excess of 2 million SCFH (57,000 Nm3/hr) of high pressure nitrogen gas for use in oil well extraction enhancement, refinery cleaning and other remotely located chemical purging applications. These vaporizers / converters had to be portable, independently powered and compact enough to fit into a very restricted space on the back of a multi purpose well enhancement service rig.
In response to other problems encountered by the oil industry in which much smaller, but still high pressure, nitrogen flow rates are required, Cryoquip has developed the VWP series of vaporizers. The vaporizer is designed to be truck mounted and self-contained. It is extremely compact in design and fits a minimal volumetric space relative to its capacity. Liquid nitrogen is supplied from a storage tank to an on board high-pressure liquid nitrogen pump. The high pressure liquid is pumped through a specially designed stainless steel endless coil that is situated inside a water pot which is supplied with hot water from the engine of the unit. The vaporizer is capable of operating at pressures up to 10,000 psig or 690 bar. The vaporizer is plumbed into the engine cooling water circuit and the engine heated water provides sufficient energy to vaporize between 90,000 and 180,000 SCFH of high pressure nitrogen gas. This gas is used to fracture wells where the flow rate demand is relatively low, or to provide emergency back up nitrogen gas.
