Overview

Pre-engineered flare systems ready for rapid site mobilisation

CRA’s Rental Flares provide a rapid, reliable solution for temporary gas flaring during maintenance, commissioning, plant turnarounds, or emergency conditions. Delivered as skid-mounted, trailer-mounted, or modular systems, they are designed for quick mobilisation and safe operation, and are designed in line with the applicable flare standards. With proven designs and global availability, our rental flares help facilities maintain safe operations without disruption.

Technology Explained

What is a Rental Flare?

A rental flare is a pre-engineered, packaged combustion system designed for temporary deployment at sites that need safe gas disposal during planned shutdowns, commissioning activities, plant turnarounds, or unplanned emergency conditions.

How it works

Rental flares arrive fully assembled and move from delivery to operation through a standard mobilisation sequence rather than on-site construction.

1
Fleet Sizing

Capacity and configuration are matched to the client's gas composition, flow rate, and expected duration before a unit is selected for dispatch.

2
Pre-Commissioning

The selected unit is assembled, pressure-tested, and commissioned at CRA's facility, with pilots, ignition, flow control, and instrumentation already integrated and wired.

3
Mobilisation

The skid or trailer ships to site and is positioned according to the layout agreed before dispatch.

4
Site Connection

Connections are made to the site gas header and utilities, and the unit is brought to operational status after the pre-start checks.

Key Benefits

1
Rapid Deployment

Pre-engineered and packaged units enable quick setup for emergency or planned events

2
Operational Flexibility

Handles a wide range of gas flows, pressures, and compositions for diverse site needs

3
Safe Operation

Integrated pilots, ignition, and controls designed in line with international flare standards

4
Minimal Site Impact

Skid or trailer-mounted units reduce footprint and ease installation in constrained areas

5
Global Availability

Rental fleet accessible worldwide, backed by CRA engineering

Frequently Asked Questions

When should I rent a flare instead of buying one?

Rent a flare when the need is short-term, urgent, or non-recurring, typically when the duration is under 6 to 12 months, or when capital constraints make buying impractical. Renting avoids capex, depreciation, and storage between uses. Rent makes sense for a plant turnaround or commissioning that needs temporary gas disposal, an emergency response while a permanent flare is offline, a pilot project or trial, pipeline blowdown, hydro-testing or one-off gas displacement, or when capital approval is delayed but the need is immediate. Buying makes sense for permanent or recurring multi-year flaring at a fixed site, where rental costs across the full duration would exceed the purchase price.

What rental terms and durations are typical?

Rental terms typically range from a few weeks to multiple years, with standard contracts at 1, 3, 6, and 12 months and longer-term agreements available with reduced monthly rates. Terms cover the unit, controls, ignition, optional operator support, and routine consumables such as pilot fuel. The typical commercial scope sets out mobilisation and demobilisation charges, the monthly or daily rental rate, which declines with longer commitment, operator or technician support if requested, maintenance and inspection responsibilities during the rental period, insurance and liability terms, and return condition and damage assessment terms. Project-specific scope such as sour service or an on-site engineer is added as required.

What's included in a rental flare package?

A standard rental flare package includes the complete flare system ready to operate: flare stack and tip, pilot burners, ignition system, control panel, gas inlet piping, and skid or trailer mounting. The stack height is set for radiation safety, the flare tip is sized for the design flow range, the pilot system is continuous with redundant ignition, the PLC control panel has an HMI and alarm logic, and the gas inlet has a flange and isolation valve, with pilot fuel from process gas or integrated propane. Optional add-ons cover an on-site operator, remote monitoring, additional fuel tanks, custom controls and sour-service material upgrades.

What decides how fast a rental flare can be on-site?

The time to get a rental flare on-site depends on the fleet location relative to the site, the transport mode by road, sea or air, site readiness in terms of pad, gas tie-in and electrical supply, which can be prepared in parallel, customs clearance for international shipments, and site access constraints such as crane availability for skid units. Pre-engineered units in the rental fleet are kept commissioned and ready to deploy, which avoids the design and fabrication lead time of a purchase. Air freight can be considered when the timeline is critical and the project economics support the cost.

What standards do rental flares meet?

Rental flares are designed to the same design standards as permanent units: API 537, API 521, EPA 40 CFR 60.18, EU IED as applicable, and project-specific local requirements. The flare stack height and the radiation exposure at grade are set in line with API 521 for personnel safety, and the pilot and ignition arrangements follow the same engineering practice as CRA’s permanent flares. The standards that apply to a particular deployment are confirmed with the client when the unit is selected.
