  • Condensate System

    When steam or hot water (waste heat from elsewhere on the plant) are used as heat source, the condensate system (in case of steam) or water return system (in case of hot water) collects and stores the vaporizer heater bundle effluent. This effluent is checked for traces of fuel to make sure the system remains perfectly sealed. If no contamination is detected, the condensate is stored in a tank, prior to being forwarded back to the heat source for re-use.

  • Condensate Storage

    The condensate storage section holds drained material from the filter separator (and/or Knock-out drum) until it can be hauled from site. As elsewhere in our system, we use proven and reliable technology and can customize the design to your exact requirements. The vessel can have an unlimited range of volumes, depending on your specific needs. Options include single-wall tank or double wall for additional containment safety, a vacuum leak detector, condensate unloading pump, various level measurements, and a flame arrestor for maximum safety.

  • Chemicals

    The process industry is changing. Chemical industries have to deal with changing views on energy, logistics, space, environment and safety. Integration of existing process systems with recovered or renewable energy sources. Petrogas works comfortably in both green-field and brown-field projects, our skid-based plants are part of the integrated solution.

  • Absorber

    The Absorber removes dissolved liquids, like water, hydrocarbon condensate, aromatic hydrocarbon contaminants and BTEX. TEG flows generally from top to bottom in countercurrent with the saturated feed gas. The contacting devices may be packings or trays in combination with several types of internals. Water rich glycol leaves the Absorber at the bottom of the vessel. The dry gas leaves the Absorber at the top via a demisting device to remove entrained droplets.

  • Inlet Separator

    The Inlet Separator scrubs the feed gas from free liquids, like (salty) water and hydrocarbon condensate, and suspended particles before it enters the Absorber. In case large amounts of water, condensate are expected this can be collected in the Inlet Separator also. Not removing these liquids from the feed gas may result in higher glycol losses, increase foaming and increase the Reboiler duty. The Inlet Separator can be stand alone or an integral part of the Absorber.

  • Flare System

    Unwanted gasses and condensates can be disposed of through a flare, reducing the emission of green house gases into the environment. Substances drained from the main system can be accumulated in a slop tank, the flare is fired up when this tank reaches a given level.

  • Liquefied Hydrocarbon Gas Conditioning

    Evaporator systems must work safely and efficiently at all times, so we build quality and reliability into our skid-mounted units right from the start. Every component, down to the valve seal material, is selected for its optimal suitability for every specific situation. Also the operating principle is fine tuned to each case. That’s why many of the world’s leading Engineering, Procurement & Construction (EPC) contractors and end users turn to Petrogas for peace of mind. We have supplied evaporating systems to refineries, power plants and industrial consumers.

  • Steam Heating Networks

    Petrogas is continuously looking for opportunities within the renewable markets. Recently we started to work on the construction of an award winning project ECLUSE. During the ECLUSE project we will lay a network of steam and condensate pipes between the thermal Indaver/SLECO processing plants and a number of companies in Waasland Port. This will enable the companies to purchase heat according to their own requirements. The heating network transports steam – generated during incineration – through an insulated steam pipe to those using the heat. The transport is done efficiently and without appreciable loss using superheated steam at high pressure (40 bar) and high temperature (400 °C). The hot water passes through condensate piping back to Indaver/SLECO where it is used once again as feedwater in the steam boiler. The pipelines will be around 5 kilometres long and will be laid partly underground, partly above ground. ECLUSE applies a solidarity principle for its heat extractors.

  • Glycol Dehydration & Regeneration

    Natural gas streams produced by the wells or extracted from storage resevoirs often contain large amounts of water (vapour). Removal of this water from the gas stream is necessary to protect equipment further downstream from damage and prevent hydrate formations that may cause complete line blockage and corrosion. Glycol dehydration is the preferred liquid desiccant system that is optimized for the removal of large quantities of water from natural gas and natural gas liquids (NGL). Glycol Dehydration systems are the most common and economical means of water removal from these streams. In practice the glycols: Mono Ethylene Glycol (MEG), Diethylene Glycol (DEG), Triethylene Glycol (TEG), Tetraethylene Glycol (TREG) and Propylene Glycol are commonly used absorbents. TEG is the most frequently used because it offers an attractive balance in initial costs and solvent losses. Water is separated from the gas when the glycol is brought into contact with the gas in the absorber column at an elevated pressure, absorbing the water. The water rich glycol is reconcentrated in the regeneration package by heating the glycol at approximately atmospheric pressure to a temperature high enough to drive off virtually all water and other contaminants. The purified/ lean glycol is then cooled down and recirculated to the Absorber. Saturated/rich glycol is then pumped to the glycol regeneration package. This package strips the absorbed water, salts, and contaminants from the Rich Glycol. The purified/lean Glycol is then ready for reuse in the dehydration process. This combination of a Glycol based Dehydration system with a Glycol Regeneration package creates a closed loop system, minimalizing glycol losses and optimizing efficiency.

  • Buffering

    The buffer consists of a compressor, a buffer volume and an outlet system (usually a heater and pressure reducing system). The goal is to store enough gas to keep the gas turbine running if the gas supply is interrupted. The buffer must provide gas for long enough to allow the turbine control system to perform actions like switching over to backup fuel (usually diesel), start pumps and adjust burner settings. Buffer volume is customized to each project, since each combination of gas pressure, consumption and composition requires a different volume.

  • Gas Filteration & Separation

    The filter separator removes foreign materials like debris, dust and liquids to prevent them from damaging downstream systems. We monitor any rising differential pressure between inlet- and outlet of the vessel, which indicates that the filter elements should be replaced. We have worked with gas supplies having high acid and salt content, always conditioning the gas to give a clean dry stream to turbines for maximum up-time. Filters are automatically or manually drained, and there are various mounting orientations for easy operation.

  • Fuel Gas Conditioning

    Gas systems must work safely and efficiently at all times, so we build quality and reliability into our skid-mounted conditioning stations right from the start. Every one of our turnkey systems is factory-tested: we QC everything, from the actuators on the inlet valves to the filter cartridges in the final filters. That’s why many of the world’s leading Engineering, Procurement & Construction (EPC) contractors and end users turn to Petrogas for peace of mind. We have supplied gas treatment systems to some of the world’s largest combined cycle power plants, natural gas distributors, and processing and industrial plants.
