A sample taken from a process pipeline or reactor should represent the exact constituents of the process without any contamination. Contamination of a sample can create incorrect test results and cause further process problems. DDPS’ range of samplers has several design features built in to overcome contamination problems and provide a true representative sample. Our range of sample dispensing options and secondary containment solutions are designed to suit the process needs of the pharmaceutical, chemical, biotechnology, food and beverage and petrochemical industries. Sampling solutions of all levels of sophistication are available from simple manual sampling to remote automated sampling and analysis systems. Toxic, flammable and corrosive media are safely sampled using systems with all wetted parts in a variety of materials of construction.
DDPS' range of inline samplers are designed to take a representative sample from a process pipeline. The sampling range includes volumetric samplers. Whether the process pipeline is running horizontally or vertically we have a range of sampling valves to suit.
The surface mount sampler is a new type of sampling valve which can be bolted on to the side or bottom of a vessel or large pipeline. In the case of a vessel mount, the valve is bolted to a pad flange on the side of a vessel.
Batch processing within reactors can be sampled with ease using DDPS' range of vessel mounted sampling systems. Samples are typically taken from a dip pipe mounted at the top of the vessel. The sample can be drawn up the dip pipe using a variety of methods:
Site vacuum
Eductor
Recirculating Pump
Pressure within the vessel
Each of the different methods have their advantages and disadvantages, our engineering team are at hand to discuss these before embarking on any particular build. Vessel samplers can be supplied with all wetted parts manufactured from corrosion resistant materials, our standard range of samplers has a temperature range up to 350ºF (180ºC) and pressure up to 150 psig (10 bar g). Our vessel mounted sampling systems are varied in their construction and often designed to meet certain specific requirements of the customers existing plant.
Depending on the properties and hazard risk of the sample to be taken, DDPS offers a variety of dispensing solutions that can be tailored to best suit your process requirements.
DDPS uses a modular dispensing connection on all its sampling equipment so that different dispensing options can be easily connected to the sampling system. By using this modular sample dispensing approach we can best match the type of dispensing option supplied with the minimum of cost and effort to the your specific requirements for containment and operator safety.
