Abstract: The present invention relates to the optimization of the processes relating to the activities performed by Onshore Production Rigs simplified with the placing of loads on wheels. The use of the equipment on a single board, called a Compact Peripheral Unit (UCP), considerably reduces the quantity of loads moved in the rig dismounting, transport and mounting (DTM) process. As a result, in addition to optimizing the layout on leases, the DTM costs and time are reduced, together with the risk of accidents.

Abstract: A mixed-bed catalytic system and its activation for direct synthesis of dimethyl ether from synthesis gas are described, comprising a catalyst for methanol synthesis and the zeolite ferrierite in its acid form as the methanol dehydrating component, the two being mixed physically in the form of powder of defined granulometry or as pellets. Another object of the present invention is a process for production of the acid form of the zeolite ferrierite. Another object of the present invention is a process for direct synthesis of dimethyl ether from a synthesis gas, using the catalytic system of the present invention.

Abstract: A process to reduce acidity of hydrocarbon mixtures (1) is described, that includes sending a hydrocarbon stream to a Microwave Treatment Unit (MTU), with a fixed stream or mud bed of microwave absorbent materials, pure or in mixtures, such as coke fines, spent catalysts that have already been used in FCC units or hydrotreatment (HDT) in a refinery, or even new catalysts which may be sulfided or not, under processing conditions.

Abstract: A process for the selective controlled reduction of the relative water permeability in high permeability, oil-bearing formations, with negligible reduction of the permeability to oil. The process comprises, for sandstone reservoir rocks, a first layer of cationic polymer, followed by a brine spacer slug and a second polymer layer made up of a suspension of anionic polymer and an anionic or non-ionic microgel, optionally this configuration being repeated. As a result the thickness of the polymer layer is considerably increased, which permits the process to be used in high permeability formations. For limestone rocks the first layer is made up of anionic polymer, while the second layer involves a suspension of cationic polymer/cationic or non-ionic microgel. The polymers are all injected as aqueous suspensions in brine or seawater.

Abstract: Described is an injection charging system in delayed coking drums (11), comprised of at least two injection pipes (11a) connected to the sidewall of a coking drum (1) in its tricone portion, and fed by a circular distributor crown, in order to allow coupling or decoupling of the large lower flange (11e) of the coking drum (1) without needing to disconnect the injection system (11) from the pumping and heating system (10).

Abstract: A modified alumina is useful as metals passivator in fluidizable catalytic cracking catalysts. The modified alumina is prepared from a hydrated alumina, e.g., gibbsite, which is reacted with a low-molecular weight organic acid, e.g., acetic acid, forming aluminum salts. Calcination of the modified alumina results in decomposition of the aluminum salt.

Abstract: A system for separating catalyst particles in the catalytic cracking of reacted hydrocarbons includes an unconfined cyclone device made up of a diplegless cyclone opening directly into a large volume separator vessel downwardly through a mouth and upwardly through the annular space between concentric pipes. The concentric pipes are connected to the other components of the system as well as the hydrocarbon fluid catalytic cracking process carried out in the system.
